what i mean by that is .... can this amp go loud enough to play along with the loudness of a drumkit

http://www.guitarcenter.com/shop/product/buy_ampeg_ba112_50w_single_12_combo?full_sku=48177 6

its a Ampeg Ba-112 50W

so can it?

probably, if EQed right and the drummer isn't a friggin' madman beating the crap out of his kit.

generally 50-70 watts is required to get over a drum kit.

The drummers I've usually played with I like to have 200 watts bare minimum. 350 to 500 would be enough to have some headroom. But it depends on your drummer and the genre too...

I'm running appx. 160 watts (300 watt head @ 4 ohms run @ 8 ohms) into a 15" speaker which gets me by fine, not as much headroom as I'd like to have though. I wouldn't go much lower than that.

I used to be able to fill in sound with a lousy 25 watt traynor amp.

I couldn't be heard, but you could tell when i stopped playing.
So my guess is yes, you could beat out the drums.

Aren't YOU the one who made this thread? If you know how loud the drums are, why make it? :rolleyes:


What I'm assuming SoM is saying is that he could be running it at lower wattages, but it would be pushing his head a bit more than he'd like. By running a louder amp being moderately pushed instead of maxing out a less loud amp he's going to have a cleaner signal and probably more longevity from his equipment.

Very astute. I was really just busting balls about the PA, glad everyone picked up on that :p

No really, you sound so much better and clearer with a big amp with the vol set to 2 or 3. Yeah I used to jam with a Peavey Standard, overrated at 130 watts and it got so hot you could fry eggs on the back of it. Eventually the power supply on that thing just melted...

WATTS DO NO EQUAL VOLUME
You can get away with a practise amp if the drummer you are playing with is any good and understand dynamics.

For a band practise you can easily get away with something like a fender rumble 100 or a good 12"-15" speakered combo.
Its nice to have big rigs but its also nice to not be crippled so don't invest in a massive rig if you aren't gigging regularly.

But man, some gigs I wish I had 4x the power I have, some of the big 700 person venues round here have ****e PA's and idiot soundmen.

db or spl = volume. this is directly proportional to Watts and sensitivity.

edgebass5
11-17-2006, 10:08 PM
db or spl = volume. this is directly proportional to Watts and sensitivity.

Well, the argument goes like this: How loud is 1 watt?

That's the be-all-end-all statement of the whole thing. Its pretty much infalible as far as I'm concerned. Obviously a 1,000 watt amp has more volume potential than a 10 watt amp, but the fact of the matter remains that 1 watt into cab A will not produce the same db's as 1 watt into cab B. Nor will it sound the same, nor will it be perceived the same, etc. etc. etc. etc. etc.

To quote directly from the Acme website:
The sensitivity, power capacity and maximum output of a loudspeaker are related by a precise mathematical relationship:
Om = (10 x log Pm) +S1, where

Om = maximum output
Pm = maximum input power
S1 = sensitivity measured at one Watt/one meter

....Show me what part of that says that 1 watt = X db and I'll promptly pull down my pants and shove any one of my basses right up my butthole! :lol:

11-17-2006, 11:36 PM
Well, the argument goes like this: How loud is 1 watt...

Your butthole aside, the fact is that 10 watts into cab A is louder than 1 watt into cab A. So the power of your amp has a lot to do with how loud you can play. How many people do you know that will stick with their 15 watt bedroom practice amp and just add a more efficient speaker so they can gig with it?

I could say "string tension does not equal string stiffness", it's just as stupid because its a blanket statement that only addresses one of many factors. But in a given rig, if you replace the head with a bigger one you'll be louder (assuming your cab can handle it). It's physics 101...

Roogen
11-17-2006, 11:56 PM
Well first of all watts are a measure of power...

So a really crappy amp can use 400 watts and sound no louder than a 50 watt amp. Its how efficient the amp is with the power it consumes is what you have to consider when buying.

Argue against my whole statement as opposed to a portion of it. And directly proportional means something different than equal to.

And the equation that you have posted here shows the direct correlation of the power amp's power supply, which you and I discussed approx 7 months ago - you saying that the power supply didn't affect the output power.

That would then be the power consumption rating, right? We're looking at the power output rating. And then with your point we still wouldn't be talking watts, we would be talking ratings.

Hopefully I can help clarify this complicated issue. Please take this simple test...


1) Turning your volume control clockwise does what?

a- Increases your hormones
b- Increases the airspeed on an unladen swallow
c- Increases your volume

Answer: All of the above (you're scaring the swallow...)

2) It does this how?

a- By modulating the gravitational field of the planet
b- By putting beans in your ears
c- By increasing the power to the speaker

Answer: c, unless it's lima beans that taste like starch

3) What units are used to measure amplifier power?

a- Lima beans
b- Swallow poop
c- Watts

Answer: 42, the meaning of life


Edge, does this help?

Wow, incredibly well-done! I'll be the first to admit that answer b to question 1 made me laugh.... but I have to wonder are you talking about an african or a european swallow? Surely an african swallow would not be scared by an increase in amplifier volume... the damn things can grib a coconut by the husk! if only they were migratory.

Now, the point that I'm making.. and have been making for a long time.... Is that amplifier power is only one part of a much large equation. So to answer question 3 yes, amplifier power is measured in watts. However, put 1 watt into a cab and its going to produce x db's. Put that same watt into another cab and its going to produce y db's. Its akin to people saying that a 1x15 cabinet will be deeper in tone than a 2x10 because the speaker's a larger diameter. You can't look at amplification in such a narrow way.

I fully understand that 1 watt into cabinet A won't be as loud as 100 watts into cabinet A, but that's not really the point of my argument.

People will constantly say things like "I used to use a 60 watt amp and get over 13 guitarists all using marshall full stacks and a drummer who's kick drum was actually an elephant laying on its side." The 60 watts part is irrelevant. Give me 300 watts and an Ampeg 1x15 and I doubt you'd be able to hear me in a full arrangement. Now, give me 300 watts and a Bill Fitzmaurice Omni 15... I bet you'll hear me with gusto :thumb:

...until the aforementioned elephant decides that the swallow in the room is pissing him off and all hell breaks loose :p

alright, i'm not getting in the watts/loud debate, but in most cases, that specific 50 watt ampeg amp wont be heard that well over a drummer, let alone more bandmates. It would be wise to just spend another hundred dollars or so and get some 1x15/100watt combo, ie ba-115, ampeg b-100r, rumble 100, crate bt100, maybe one of the new behringer amps. <--not sure about all of those, but for a little more it would be worth it over the ba112. just my thoughts.

haha, i just remembered about the newer fender bassman amps, it looks like the Bassman 150 would be nice, still has the 1 12" speaker, but 150 watts, so it would be twice as loud. hehe.

Too bad it was the last post on the page because no one else will ever look at it :p

I think we understand each other. I agree that it's important for people to realize that speakers have different sensitivities. And some people may not realize that a 3db increase in sensitivity is the same as doubling your amp power.

For me, I only use stacks, I've never owned an "amp" other little practice amps. I choose cabs based on sound, portability, power handling, and load (ohms). Then I add a head that can drive it to the level I need (ie, want). So for me, amplifier power is a VERY important factor.

That's not what I'm saying at all, you haven't read my posts clearly. Look at it this way:

Wattage A into Cab A results in Volume X
Wattage A into Cab B results in Volume Y

Saying that you have "blank" number of watts gives no indication of how loud the rig will be. As another example, I drive my rig with a 1600 watt QSC PLX1602 running in bridged mono into a 4 ohm load. If you used an 800 watt amplifier with my rig it would be just as loud as my 1600 watts since probably only 500 are being used to drive the cab most of the time. The remaining wattage is nothing but headroom, yet despite the fact that one amp is twice as powerful as the other, there's no discernable volume difference.

:thumb:

A lot of the confusion about the ACTUAL power output of amplifiers comes from the fact that there is no standard benchmark under which amplifiers are tested.

A while back I did a comparison between the Mesa M-Pulse 600 head that I used to own and an Ampeg SVT-4Pro (running in bridged mono with an appropriately wired speakon cable). The 4Pro is something like 1200 watts into a 4 ohm load if I remember correctly, whereas the Mesa is 600 watts into a 4 ohm load. The Mesa was just as loud as the 4Pro all the way to the point of being uncomfortably loud. This makes me think that the frequency used to test the Ampeg was much higher than the Mesa giving it a seemingly higher power output rating. Since no one lists what their test frequency actually is its pretty much impossible to get any truth out of listed specifications... 'tis sad, 'tis true :lol:

EDIT: Something to note about the comparison I did. Both heads were going into the same cab, therefore neither could be run at the same time. Both amps were set to their respective flat EQ positions. Most noteably, the cab in question farted out before I was able to get either amp to start distorting, so the 4Pro may very well have beaten the Mesa at the very top end of its output... but it certainly wasn't shaping up like that based on volume/gain knob positions.... Just thought I'd say that to clarify :D

EDIT: Oh, and furthermore, not all 2x12's, or 4x8's are created equally. One manufacturer's 2x12 design will more than likely have a different sensitivity at a given frequency. Until manufacturer's start publishing SPL charts measured at an equal benchmark across the board its impossible to accurately compare two speaker cabinets by any method other than actually listening to them.

I understand what you are saying and I agree that it is correct, but I don't think uoy are understanding my point clearly.

I said watts is an easy way to ROUGHLY measure how loud its going to be. Thats not to say that a 100W amp is going to be 24.678483dB louder than a 25W amp. It's more like a 100W amp is going to be louder than a 25W amp, but we don't know how much because watts does not equal volume. It has a lot to do with it though.

That's so stupid. You cannot change two variables at once and get a valid outcome. A better setup would be a 25 watt amp with a good speaker, and a 250 watt amp with the same speaker. Which will probably be louder?

I still don't agree that watts can even be a rough indicator of volume. As I've said before, wattage A into cab A will produce a different volume level then wattage A into cab B.

Now, let's look at a different scenario: Wattage A into cab A versus wattage B into cab A. Since doubling the amount of wattage fed into a speaker cabinet does not double the volume it becomes very blurry to ascertain volume increase based on watts. Theoretically it will require roughly 10 times the number of watts to equate to double the volume out of a speaker cabinet. So how many more decibles can you get out of cab A while pushing 300 watts into it versus the same cabinet being powered by 500 watts?

Add to that the non-common benchmark at which amplifier power is measured, and no clear way to tell what your amplifier is actually putting out (save for actually metering the output with a multimeter), and you're STILL left with the fact that watts do not give a clear indication of how loud a rig will be.

I've made my point several times over, and have done so in a multitude of different ways in this thread. I'm done debating over it. If you want to believe that watts are more than a small piece of a very large puzzle then be my guest, however wrong you might be...

That's so stupid. You cannot change two variables at once and get a valid outcome. A better setup would be a 25 watt amp with a good speaker, and a 250 watt amp with the same speaker. Which will probably be louder?

Why not, these variables change from amp to amp.
Thats why you cannot use watts as any kind of indication to volume.

But if we are talking two rigs the same minus wattage, it is indeed at least a rough indicator.

Edge, you have to understand, this is all in your analytical mind.

This is the real world:

We've got two Hartke amps, both of the VX series, both are 4x10. One is 300W, one is 500W.

Which is louder?

No way in hell a company will make an amp less louder and have more watts than another model of theirs.

Watts CAN be used to know which amp is louder in the right situation. The right situation is a bitch to get (I mean, same brand, similar models, roughly the same speaker configuration), but it's attainable.

Sure, it's possible the 300W is louder than the 500W, but a company wouldn't pull off this MINDFREAK on anyone.

I realize that I said I wasn't going to debate this anymore, and I apologize for feeling the need to get back into it... but your post has really missed the mark of what I was saying entirely.

300 watts into a Hartke VX cabinet is not going to be as loud as 500 watts into the same cabinet. That's a given. I'm not arguing against that at all. If that's what you think then you really need to read through my numerous posts on the subject.

As to the "real world" comment. I am discussing the real world. People suggesting that wattage is an indication of loudness are the ones discussing some fantasy world where all speakers and cabinets have the same sensitivity and frequency response, where all amp companies set their maximum output wattage by means of a common benchmark and publish truthful and accurate SPL charts, and where magical unicorns bless all players with the ability to play like Wooten, Pastorius, Hamm, and Sheehan at the same time... Here in the real world watts do not equal volume, nor do they serve as a useful reference point to ascertain the potential volume of a rig.

Saying that they do is like saying "Hey that house must be really nice because it has a really great looking front door." Sure the door might be nice, but what's the rest of the house like? Is the roof in need of repair? Are the carpets stained and filthy? Sure the amp puts out 10,000 watts, but what's it hooked up to? Is it going into a high-efficiency folding horn style cabinet, or is it going into a low efficiency direct radiator style cabinet?

The volume of a given rig (with no effects or other devices in the chain) is equal to:
output voltage of the bass - input impedance of the preamp + output voltage of the preamp - input impedance of the power amp + output wattage of the power amp / total impedance load of the cabinet(s) + output sensitivity of the cabinet(s) factored against EQ settings exclusive of their effect on the overall output voltage of the preamp, room acoustics, and any mental placebo effects of the user

If you can condense that equation down to the point of saying watts = volume then (to quote Bill Fitzmaurice over on Talkbass), I'll eat my cabinet, all the way down to the magnets. :lol:

I was only arguing the part where you said watts was NO INDICATION AT ALL regarding volume. You analyze too much, including my posts (mainly saying this because your reply goes MUCH farther from anything I had implied in my post).

Watts can indicate which is louder in certain scenarios. You can't indicate how much louder it is, but yo ustill know which one is louder.

And the "real world" comment mainly regard brand name companies and their way on working. People can think what they think, I didn't refer to them at all.

:lol: at what this thread has become.

I give up arguing ok cause I really don't know that much about what I'm talking about.
