Even Earl uses floor absorbers and ceiling diffusers to tackle the floor and ceiling reflections.
Thanks for reminding me of need for this acoustical room treatment. It will no doubt be essential for success when I install my horn system.

The temptation with any supertweeter is to turn it up a few dB so you can hear it do its thing. Not that different than turning up the sharpness control on a HDTV.

What I did hear was clean as a whistle (no apparent distortion or overload), and no issues from the vertical diffraction horn. I think the absence of a hard, reflective phase plug probably makes a difference.

Credit where it's due to the Wavelength electronics (source and amplifiers). Very transparent, dynamic, and with good tonality.

Ditto surround sound channels. They are usually up too high, so that you will notice them.
That's one of the first things you learn when doing THX or other cinema alignments.
Take the Speaker Voltage Test!

Hi Lynn,
Seeing the beyond Ariel thread compelled me to pen a brief 'thank you' directed to you. Back in the early days of the Ariel I built a pair and fell in love with the sound. I had never really heard tube based HiFi before, nor speakers of the quality of the Ariels. Frankly, it all had a profound effect on me. After listening to the Ariels for a few years--trying different amps and pre amps, turntables, cartridges, etc. with them, I moved on to other speakers of various types--always looking for that synergistic combination that would totally enthrall. And, like many others, I lost my way.
In the last month, I went back to where it all started for me. I put the Ariels back in play, dragged out the monstrous W75 Allan Organ 6550 ultralinear amps modified to triode mode and am trying to get my Dynaco Pass 3x pre amp dialed in. Even with this 'work in progress' pre amp situation I am enjoying beyond description the sound being created.
So, just wanted to tell you how much your selfless contributions have given me so much joy.
Thank you.

Do you have pictures of your floor to ceiling array?
