So, I blew a speaker in my Ampeg SVT-410HLF cabinet, which I play through with a Gallien-Krueger 800RB head. I really have very little understanding of ohms and impedance, and I want to make sure that if I can't get the speaker fixed for a reasonable price, that I buy a speaker with the proper ohm rating. I'm currently looking at the <A href="http://www.usspeaker.com/legend%20bp102-1.htm">Legend BP-102</A>. It has the same voice coil size as that listed on Ampeg's site, and it actually looks very similar to the damaged speaker I pulled out of the cabinet. However, the cabinet is a 4 ohm cabinet, and the Legend BP-102 is an 8 ohm speaker. The speakers are bridged in a bass cabinet like this, reducing the overall impedance to 4 ohms, right? Will this replacement speaker be suitable?
