HTB2 sub placement
I have an HTB2SE, and I finally just picked up a second sub, HTB2, on ebay to hopefully even out the bass response.
I'm going to try front/center with rear/center of the room, as well as both up front with 1/4 width placement. My question is, since these 2 subs have passive radiators making them fire in both directions, how close should they be to the wall?
Bonus question: Does anyone know the difference between the HTB2 and HTB2SE? I've looked all over online and even e-mailed KEF with no response. My SE sub actually says "HTB2" on the bottom - no mention of SE. However, it came in the SE kit, and it weighs just barely more (as indicated by the SE vs. non-SE specs). The units are identical on the outside except for one difference: the bass boost switch on the SE has 0, +6db, and +12db, where the bass boost switch on the standard I just got has 0, +3db, and +6db. If anyone knows what the actual sonic difference between these 2 are, I'd be really interested. I ran a sweep on both of them, and they seem to output the same.
