Crossover

[Mr. Pickle]

So on my cab, it doesnt really have a crossover, it's just more or less the head connected right to the speakers. it seems when i start getting pretty loud, the 2 10's (it has 1x15 and 2x10's) seem to start clipping and the cone seems to start to rattle (more horizontally i guess, they kind of pop in and out instead of vibrating, and it's not due to being loose or not having enough weather stripping, etc.) and make this weird low freq. slow vibrating type noise. is this due to not having a real crossover or is it just the head? (bx3000t)

k,

Too much power? What is your cab's rating, frequency and power? You really won't need a crossover unless you have a tweeter, in which case you can make one by just adding a capacitor.

[Mr. Pickle]

they're all carvin woofers and are all rated at 600 i believe

[bbbbass]

Hmm, I guess I would have to hear/see it to know exactly. Carvin's are well built, and hopefully your problem has an easy solution.

well, most of the time a crossover is used to separate the signal from the woofers and the high frequency drivers (i.e. tweeters, horns, etc.). It sounds to me like the 10's in your cab are being driven too hard, or you're clipping your amp and sending a DC current through them which will cause them to fart out like that. I can't really imagine using a conventional crossover to separate between a 2x10 and a 1x15 (although, my Fender TBP-1 does have that function)

[Mr. Pickle]

well do u have any suggestions on how to fix this?

Well, without knowing exactly what it is, a reduction of bass frequencies in your EQ might do the trick. A reduction of one of your gain stages might fix it if its a clipping problem. Otherwise.... not sure without seeing/hearing it first hand.

[Mr. Pickle]

reducing the bass does help but when we're really playin loud my bass has to go way down, and i dont like it

[WHoRRID]

then u may want/need to invest in a new head.

[edgebass5]

^^^Exactly, it sounds like a case of wanting more than your equipment is capable of

[Mr. Pickle]

well thanks guys, that is actually kind of good news b/c now i know i need to get a new head before a bass. i've been lookin into those options you gave me edge, they seem really cool.

inform me though, if i have to turn my bass down to make it sound better, what is my equipment lacking? not disagreeing, just want to know.

It might also be that your head isn't pushing the cabs enough. It sounds like you're getting a very simular reaction to when I was trying out heads and cabs, and the head just didn't push the cab enough...

[Mr. Pickle]

alright well here's whats next. i found a qsc rmx 850 (the power amp edge suggested) on ebay for $190. I guess my question is, do power amps just come with power cords or is there something else that should be with it? it seems like thats all it would need, but i've never bought one and i dont know. thanks
