i have a profile 600 msx amplifier and a thunderform what is a high quality subwoofer that will bump in this enclosure without modification to the enclosure.

Find out the specs on the existing sub in there at www.mtxaudio.com then find the volume of the enclosure.

Subtract the volume of the sub from the volume of the box, and you'll be looking for a sub with the same edge diamter (not cone diameter), mounting depth, and volume requirements.

It's been a while since I've looked at subs, but the JL0s might work, Polk, and IDQs might be a place to look that require small volumes.
