Stereolith Loudspeakers Question

When matrixing is used, maybe. Additional drivers are on their way. Hope to have something working soon.
Did you ever get to measure the level of first side wall reflections vs. direct sound in your box?

Do tell us more

I measured with soft dummy head:

See post # 153
Stereophonic Sound from a Single Loudspeaker

At the listening position side reflection is at least 5 dB stronger than the direct sound for a side amplitude panned sound. And, the difference between left and right ear is even more bigger ! I think left-right separation is the key for succesfull image steering.

Just more FRS8's.

Is there an impulse response as a sound file I could download?

You mean like in two speakers to the left and the right in front of the listening position? That has been invented already - it's called stereophony

But unfortunately it does not work very well

No, I mean getting the perceived effect of interaural cross talk to a enough low level, so that for example small head movements do not produce perceivable image shift due to comb filtering of the interference pattern.

Just surfing..

It appears that side firing single box stereo speakers are generally more common than would appear if only reading this forum.. on the other side of the world.

There are numerous of these designs, a tube or box, two full range elements on two sides, and a stereo speaker is born !

Handy. And as we know, it sounds very good in a small room
