i dont really have 4ft clear space even,wil i stil get some gain/?
but how much :-S

also,should i measure my room and guess the resonances?because its a bedroom,and its 1.9mwide,and approx 2x that in length.its low ceilings also.

2nd question : is the 6ft clear space reccomended alot,becase the 'response on the pispeakers site,show that the speakers by themselves are often -6db at 50hz for example...so i dont want that situation with no room gain because its crammed with furniture :-D

am i right saying that u can have much smaller boxes because the resonance can be higher ,using room gain?
and its simply a ported box ? with those side slots?

if so,send me some plans wayne :-D im interested in a few Db more effiency for free :-P
meanwhile,il test out the pi align program :)

• my crapy site,oneday il fix it

Certainly, the best room would be one with clear wall space from the corners, adjacent room boundaries would be rigid and opposing boundaries would be perfectly reflection-free, either open space or fully absorbent. Obviously, this is not the case. The adjacent boundaries aren't fully rigid, nor are the opposing boundaries absorbent. But I've found that homes with a concrete slab and framed drywall construction provide a good environment for cornerhorns. The drywall is lossy, and it and the insulation behind it tends to damp the room. That's probably the single biggest thing in small rooms, you really need this damping from walls that have some give. This damping smoothes room modes, making bass more uniform.

volfenhag or performance technique or somthing?/?
like 50 -80 US $

maybe here ,if ur lucky it was awhile ago..

Do you remember in Good Morning Vietnam when Robin made up the interview with gun Sargent and he asked him what to play? He said he didn't care, just play it LOUD ???

I'm guessing the same can be said at your home :o.

Grant.

actualy,i prefer Low Q bass,no room walls buzing and midfi sound(whatever that is defined as)

does it make any diff u if u run ur NORMAL sub in the corner,then run a Pi 6 in the corner?? ???? ./cos i already have it there..
:-)

like i said,if that room sucks,i got 2others, 4.5x5.5m.

so there :-P
