Re: 2 PI - maximum volume to avoid Helmholtz standing waves
How about a sideways 2Pi:
Hey Wayne, can you crunch the # to see where the best position for the driver and port are?

Thanks!
I will try to keep the enclosure very close to the small bookshelf, and will keep looking for those spreadsheets.
I will let you know my findings
Saludos,

Re: 2 PI - maximum volume to avoid Helmholtz standing waves
I can't say 'cause I haven't done that. On the little model, I'd be pretty comfortable that it wouldn't cause ill effects but I wouldn't be as confident on the larger tower model. The bigger boxes are where things get dicey, and you'd be surprised how ...

Re: 2 PI - maximum volume to avoid Helmholtz standing waves
Yes, I was looking for those spreadsheets a couple days ago, based on your suggestions to other users, but sadly they are not available anymore (it says "restricted access").
If I rotate the bookshelf version 90ยบ then I end up having 10 x 22 i...

Re: 2 PI - maximum volume to avoid Helmholtz standing waves
Thanks Wayne,
Which software do you recommend to run those models before being physically built? (hopefully something not very complicated).
I've checked this software:
1. BassBox Pro (same or very similar to the Eminence one)
2. WinISD
3. Pass...

Re: 2 PI - maximum volume to avoid Helmholtz standing waves
The bookshelf version is small enough that standing waves are in the upper midrange where the insulation is pretty effective. They're damped very well. But larger boxes boxes (like the tower model) have standing waves in the lower midrange and upper mi...

2 PI - maximum volume to avoid Helmholtz standing waves
Hi Wayne,
I'm preparing myself to build a pair of 2PI to be used primarily as stereo speakers (not for home theater or anything like that), so they need to be as full range as possible.

Re: 2Pi Help...
Hi etet

2Pi Help...
I have had my orignal 2Pi speakers for a few years now and every time I try something new I always end up going back to them. Now I need to build a set of 2Pi towers for a gift but there is an issue. Due to space and aesthetics they can be only 41" (e...
