i play an old p through an old svt and i need to replace the speaker in the newly added 15" cab that i want to use with it.any thoughts on what would be a good and what would be the best speaker? also what would be a fair price?and what´s the deal with ohm?the svt has 4 ohm-will it hurt it if i connect a 8 ohm cab and play loud through it?thank you

what cab is it? Speakers need to be matched to cabs. The dimensions and porting of your cab determines the speaker that will best sound in it. 8 ohm speaker will work but only get half of your power. The downside is if you go with a 4 ohm speaker then you won't be able to add another cab in the future. Your old SVT would easily push (2) 8 ohm cabs. You need to post what cab it is so people who are more knowledgeable than I am can jump in and give you a better idea of the proper speaker to use. If it is a custom cab then you need to post specs on the cab.

Yes. It is likely to cause serious damage to your amp. The output is rated for four ohms. Get a four ohm speaker.

you will not damage the amp running an 8 ohm speaker in a 4 ohm cab. The 4 ohm is a limit and anything above it can be used but you will not get the full power. (2) 8 ohm cabs = 4 ohms and can be used. But you cannot use (2) 4 ohm cabs because that equals 2 ohms and would go below the limit allowed. There are a few posts on the this forum that clearly explain Ohms. I was unclear when I first started and TalkBass helped me out.

with thought behidn what he said, an 'old' SVT would imply that he is using an all-tube head, which WOULD cause some considerabled damage.

Dude, that's for solid state heads, not tube heads. And an SVT can do 2 ohms but not 8.

did not know that about tube heads. I had a tube svt head back in the 70's and did not have a clue about ohms then. All I knew was that my (2) 8x10 cabs sounded great. I am going back and read the amps FAQ and catch up. Thanks for the info and sorry about the incorrect info :crying:

Eh...I've been there before...many times. At least you were correct as it relates to SS amps. Much of my stuff was just wrong. But like I tell people, I'm a musical genius, not an electronic genius ;)
