I tried the BK Advance for a week and was underwhelmed, and having them bottom out is the worst sound I’ve heard to date, including clipping a subwoofer. Perhaps the LFE would have provided me more of what I was after, but it was a short lived demo for a reason. 20-30Hz TR is fairly easy to get, so I expected more out of them.
A huge shout out to the BOSS thread and its recommendation, as it’s truly awesome for the money. For the price of one BK, your 300w amp will easily power 3 of the recommended JBL 12” drivers and materials to build a simple setup, should you need that many. Yes, the BK take up a little less space, but for the money, the TR provided from a BOSS is unrivaled.
I’ve got Crowson’s as well, and they do shine for very deep ULF, but a BOSS is phenomenal for the money and can be scaled to your setup. I’d recommend it over anything else for the money ten fold.
Good luck in your bass adventures!
