I have 2 Boston G5 Car Audio Subwoofers (sound quality type) For home use?
 
Is there any way to tell from the Parameters in my manual if this subwoofer will be a good candidate for Home use? Reason why is I have 2 of these sitting around and I have the itch to maybe incorporate these into my new 2ch. So would that be a 2.1? or 2.2?

If I posted the parameters could someone help and guide me through please?

Hi Derek,

A T-TQWT using a single driver would be enough for use as a main high SQ HT sub. :)

Based on those specs, I cant see any reason why not.

How would I go about finding which kind of enclosure is right for the G5.
What is a T-TQWT? I looked at the picture that bjorno sent and I cant enlarge it to see what he was trying to say.

EDIT: I found the expand button for the pic. WOW I really have not a clue what im looking at here. Can someone summarize the the graph that bjorno posted please?

Thanks again
Derek.

Those are really nice drivers. They will work well in sealed or ported enclosures, as well as a lot of the more esoteric stuff like bandpass boxes or tapped horns.

Run them off a decent pro-amp, you'll have plenty of power.

Bjorno's response is a compilation of hornresp screengrabs. Hornresp is free software that many of us use to model front and back-loaded horns, tapped horns, and TTQWT (Tapped, Tapered Quarter Wave Tube) enclosures.

We all have our favorites, we all have our reasons. Personally, I like the performance of these drivers in a tapped horn, but it is not a small box.
