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: Questions about Pi Speakers
I agree with you. One of the first things I observed was that high-efficiency loudspeakers were preferable to speakers with lower efficiency. I'd say sensitivity it's second only to tonal balance in importance. Next would be directivity followed by ...

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: Are subwoofers worth it?
If you can tell the subs are on, you don't have 'em setup right.
I used to prefer systems without subs until Todd Welti introduced the multisub concept in the early 2000s. I expanded upon it to include the concept of flanking subs. Both approaches s...

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: 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...

Re: Why is drywall bad?
That's true. Rooms with framed drywall construction are much better than rooms with brick, stucco, concrete or rock walls. The drywall panels vibrate enough that they absorb some of the bass frequencies, and so act a little bit like panel absorbers.

Re: Small-room acoustics
Actually, small rooms are harder to work with than larger rooms. The reflections and room modes are more intense in a small room. Speakers that can provide uniform directivity help reduce problems in the reverberent field, above around 200Hz, and as yo...

Re: The subwoofer volume and crossover
The answer to that can range from simple to complex. So let's start with simple, move towards more complex topics and then leave it to those interested to research further.

Re: Placement of the speakers
Left and right mains should flank the video screen, and be at the same vertical height as the screen. The center channel should be centered and at the same height as the screen. That's only possible of the screen is acoustically transparent, so some pe...
