I have a sealed 15 in cab. I had it built for me a long time ago and want to replace the JBL speaker presently installed. The cab is a cube cab that was popular in the 90's. I need suggestions on what would be good replacement.

Speaker replacement

Hello! What frequency range do you need for your replacement specification? In other words, what does your new speaker need to go down to to satisfy your requirement?
Nothing is wrong with the speaker except it is a 8 ohm and I need a 4 ohm. As to sound I am looking for something to reinforce the low bass, through low mids. It will be part of a bi-amp system.
The output difference between an 8 ohm and a 4 ohm is not that much. Even if it allowed you to double your wattage, it would only gain at best +3db (and that is if the speaker can cleanly turn all the extra wattage into sound).
Also, if bi-amping, you would only need a 6" driver to handle the rest.
The cab i will be using with it is a 4 ohm cab, biamp or stereo mode. ... also if i use it alone my thinking is my amp pushes more wattage and will give me more headroom.
Legend Ca154? Seems about as close as possible to ticking all boxes. F3 just under 90hz in a small sealed box according to eminence provided designs.
The cab i have is 2x2x2 sealed .. Might be a bit bigger. The specs on that speaker 2.5 cubic feet in a sealed enclosure.
If you are running bi-amped, it's not necessary for both cabs to have the same impedance. The outputs of a bi-amped setup are independent, basically a stereo amp, and they can have an 8 ohm load on one channel and a 4 ohm load on the other.
As Bass_Pounder pointed out, you really aren't going to get that much louder on output. You're not going to get double the volume!

Well I would like to thank everyone for helped out. I'll just keep it the way it is. You all convinced me I'll be wasting my money.
