Re: 3Pi Sub plans, and some other questions.
You've got mail! Vented and sealed subs are generally pretty tolerant of modifications. They are acoustically small, so standing waves don't setup inside. So basically, as long as the internal volume and port remain the same, you can expect performa...

Re: LSAF 2018
My room sounded great, especially for a hotel room. To be honest, I've done this show for nearly 20 years now, so I have it down. I know exactly where to put my speakers and how to setup the equipment. I always bring either seven π constant dire...

Re: Custom home theater room
I've had the most consistently good results from rooms on concrete slabs with framed drywall construction. Drywall is pretty lossy and acts like panel absorbers. Rooms on hardwood floors over crawlspaces are often problematic though. Second floor room...

Re: Concrete Vs other types of wall
Concrete surfaces on all six sides (4 walls, floor and ceiling) are problematic because there is so little damping. Reflections are strong and room modes are terrible. Even if you tame the high-frequency reflections with absorbent materials, room mode...

Re: Dead Spots
Yes, that is typical and it is the result of room modes. Read about multisubs and flanking subs. That's the way to get smooth bass which is uniform in all locations in the room. In the meantime, you may be able to mitigate the straight-on dead-spo...

Re: 7pi plan and guidance request
That room will work very well with constant directivity cornerhorns. The seven π constant directivity cornerhorn generates 101dB/W/M and is capable of over 120dB/M at full output. I would put the seven π cornerhorns along the 15-foot wall, just as ...

Re: 7pi plan and guidance request
If you have the right corners, I would suggest using the 2226 drivers in seven π constant directivity cornerhorns and make subwoofers from the 2242 drivers. Put the subs in opposite corners or somewhere distant from the cornerhorns, in a multisub config...

Re: Custom home theater room
Most times, you can work with what you've got and expect at least reasonably good performance. There are some very difficult rooms though. Examples are basements (or any room with hard walls), very long narrow rooms, very small rooms and rooms with hig...

Re: Small rooms are harder to get good sound?
Yes, small rooms have more problematic room modes than large rooms. The larger the room, the further away the reflections are. This is good both for delay and intensity. Rooms that are very large act more like an anechoic (reflection free) environ...

Re: The subwoofer volume and crossover
I was generalizing the concepts and using "round numbers" in my earlier post above. Flanking subs are setup to blend generally in the 100-200Hz region, but in practice the blending region is shifted a little lower than that. Distributed mul...
