The best speaker you ever heard?

Which of John's speakers was that?

Squarewave Speakers states:

So if the loudspeaker cannot reproduce a square wave much less it cannot and will not reproduce music accurately. THAT IS A FACT AND NOT AN OPINION!

True Dat !

Squarewave.... didn't JD speakers use odd order X-over's, i believe very similar to the Duntech's prior.

Do you produce speakers of your own design for sale commercially?

Yes, ability to pass a square wave is also a claim to fame for full range walsh drivers like those found in original OHM Fs and As.

That was their strong point. They had other weaknesses, mainly reliability and ability to go loud.

Newer OHm Walsh line speakers address those weaknesses however their 2 way design using the wide and not full range Walsh driver also now compromises ability to pass a square wave to some extent as a tradeoff from what I have read.

Is there a full range speaker that can pass a square wave without other significant compromises available today?

Duntech always touted that the Sovereign and Princess could accurately reproduce a square wave, and had the graphs to back up the claim. I believe they are still in production, though I have not checked their website for a while. Dunlavy as well, as was noted above, though they are no longer in production, sadly. I'd be curious if other speaker manufacturers make this claim.
