Re: Midhorns and boundary loading
Both horns will have nearly the same response in small to medium sized rooms (provided driver breakup doesn't do weird stuff above 1kHz). The differences will be a little easier to notice outdoors. Even there, the biggest difference will be fullness of...

Midhorns and boundary loading
The 9π midbass and midrange horns were designed to work properly in true freespace, flown outdoors. When used indoors, you can usually use a smaller horn.
I've found that horns designed for use below 300Hz are able to get boundary loading in small ro...

Re: Help please ... from the bottom up
Response for the tower two π speaker looks like this:
This is a pseudo-anechoic measurement, so the bass isn't shown. The towers have nice, deep, full bass though. To put numbers on it, f3 is 40Hz and f10 is about 30Hz.
Its impedance curve ...

Re: Reports from LSAF '09
I thought it was a great time. Turnout was good and the hotel was really pleasant. I'd be happy to come there again next year.
You know, if you're a small niche business, then you have to invite customers to your shop or home to demonstrate your produ...

Re: 7 Pi treble edge!
I think multisub is the way to go, in spite of the extra complexity. If you're looking for the best bass, the multisub approach is the way to get it.
Beyond that, there may be some issues in the upper modal range, which is actually fairly low in freque...

Re: Subwoofer help
My advice would be to purchase more than one of whatever you choose. By placing a few bass sound sources around the room, you can make bass response smoother. The peaks and dips caused by standing waves in the room are averaged out - where a valley in r...

Re: Questions on the 12 and 3 pi subs
Check your mail - I've sent plans.When using subs for prosound, use baltic birch. It's much more durable and it's lighter than MDF too.You decision about whether to use one 12π hornsub or a small group (say four) of the three π subs should be entirely di...

Cornerhorn implementations
I'll try to answer your specific question first, and then move on to "the bigger picture."
The Omega 15 is a better woofer than the Delta 15. Not that the Delta 15 is a bad woofer, I find it very pleasant sounding, but the cast frame, lar...

Re: Three Pi Towers ?
You can certainly make the cabinets larger, but you'll need to modify the port to keep the same Helmholtz frequency. The Delta 12LFA works well in cainets fom 2.0ft3 to 6.0ft3 tuned to 30Hz. Larger cabinets develop deeper bass.One thing to watch out for...

Re: Single sub bad - multi subs good
I agree with you about running subs and mains as stereo pairs. If outdoors or in a very large room, I'd also agree about keeping subs and mains within 1/4λ at the crossover point. That's essentially what you're saying, I think, when you talk about being...
