I'm not so worried about the quality of the bass as the direction of the bass and the ability to position the speakers.
Ports mean they need sufficient distance from a back wall.
Here are two unibox sims I have, one ported, one sealed.
Simulation is of 2 drivers in parallel.
You can see that you wouldn't lose much going sealed, because of the low Qts.
The Qts of this woofer is almost identical to an LMS 5400, yet almost everyone uses the LMS in a sealed configuration, though I realize the application is not the same as one is a subwoofer and the other is just a woofer.
I'm interested how a supercharged version of the B741 would sound using 4 x Scanspeak 18WU drivers in sealed configuration as compared to the original design.
Most likely it's a waste of $650 per speaker, but that's exactly why I'm curious.
Also, how would changing the shape of the cabinet for allow for BSC affect the performance?
It's interesting to see that the the crossover frequency has a wavelength the same as the width of the cabinet.
How does this affect the overall sound?
