My boss owns a rental hall and purchased a JBL MP418SP about 4 years ago for use on the dance floor. He put it in a storage closet about two years ago and hasn't used it since. I recently thought about trying it out in my living room as a mid-bass module for use with my dual av123 MFW-15 subwoofers. It is capable of very high output from around 45 Hz and up. It might be a fun experiment.

Of course you need a much larger box or limited low frequency extension to get significantly louder. If you are building a subwoofer to not go lower than 35-50hz which will be augmented, i would say in most cases that a few quality 15" drivers in the right location will trump the larger drivers in more manageable box sizes.

My doors are just 32" width. I think the TH-221 half cut/Terraform XL would just make it so as to fire the port through the doorway. LOL! I could put it on a custom trolley board and roll it into the storeroom when I'm not using it.
But seriously nowadays the main factor for most must be economy/$$$. No money, no talk even if it has the best value out there.

Now back to making those new Audiopulses pls! LOL!
