Tonight listening to music fairly loud, hitting the peak limiters in the iNuke 3000 DSP, suddenly I had red rings of death. I did have a saved preset file, and also some screen shots of the DSP settings. The amp made 6 years before it failed.

I like your format. Even though the room will dominate in the actual measured response, outdoor GP is the best measure, since all devices are on an equal playing field. A 'FAQ' or frequently asked questions section on your website can answer a lot of the same repetitive questions that can tie up your time replying to inquiries. Well informed customers can then email you for additional information on your products.

Now that I have spent time with voicing the speaker, I haven't worked up the ambition to dial in a crossover on the Behringer DCX 2496, and move to the QSC power amps. Not to mention the other projects on the go! Cold weather puts a damper on working outside.

You just need the right guy to move and install those wooden refrigerators. https://en.wikipedia.org/wiki/Magnús_Ver_Magnússon

In a low volume setting, I would agree. Once the levels get above where the typical domes run out of excursion, there may be some that can tell the difference.

Life has been busy, second and third are partially finished, but not complete.

The product page says edgewound coil: https://www.svsound.com/products/pb16-ultra Taking a stab at the finished enclosure dimensions after bracing and ports of ~ 7.5 cubes and plugging in the numbers in WinISD, letting it autocalculate the unknowns, the actual power across the coil looks surprisingly low, with a 47 ohm impedance peak in the 40 hz range.

Absolutely. In the Maelstrom-X drivers, there was a big nut glued behind the dust cap. Of course, one could go to a metal cone, which would aid in heat transfer, but that step is $$. Paper cone and $3.00 nut is more cost effective to use.

Perhaps, all though I would like to see a bit more compliance than their typically rock hard suspensions, and more throw.

Now box # 2 has 4 sides and most all of the bracing glued and screwed in place. More biscuits were used compared to the first one, and alignment of the panels is a lot nicer. Starting on #3, but weather is going to hold me up for a few days. With parts cut in multiples and pre-drilled with the Kreg jig, assembly is a breeze. Also, it helps having 20 pistol grip clamps in addition to the corner clamps.

Starting assembly on number 2 and 3.

Playlist shows up for me, but I haven't subscribed to TIdal, so I can't tell you if you can play from it.

Agreed, humans can hear below 20 hz, but that also requires high sound pressure levels, and can be masked by higher frequency content reproduced at the same time. Agreed, this article was put forth prior to the birth of the compact disc, DVD, DVD-A, SACD, Blu-ray, etc, when only tape, vinyl and shellac were the playback mediums.

Try searching for "Audio Specifications and Human Hearing" by Mark F. Davis May 1982 Stereo Review Magazine.

This subject was touched on in the last thread on instantaneous loudness, where the topic moved to perception of sound, and some good discussion resulted. MFD_SR.pdf

I like your idea, and it wouldn't be hard to implement in your case. I would be interested in hearing your subjective impressions of the pseudo line.

Kvalsvoll, have you tried any of the Danley Sound Labs recordings? http://www.danleysoundlabs.com/tom-danleys-mic-recordings/ A friend of mine who has spent many hours behind the handlebars of a shovelhead was downright shocked at the realism afforded by the recording of Donny's Harley. You could 'feel' the individual cylinder pulses from ~ 4 meters away. I tried uploading the zipped file, but it exceeds the attachment limit.

There are a few Cirque du Soleil recordings that are on Youtube, you might have to search for good uploads. Having attended a few of the shows in person, I have to say that the recordings are very good representations of the actual events.

A baffle of infinite size can be considered a 180 degree horn. The acoustic impedance will change rapidly from the mouth of the horn to the baffle. giving rise to diffraction, unless there is absorption, or a very large radius at the mouth where it transitions to a baffle, but this also depends on the frequencies of interest from the horn, the dispersion and the physical sizes of the device in question. In other words, diffraction and re-radiation is still a real problem for horns of finite dimensions.

The .PDF from Electovoice is no longer available on their website, but I had a copy on my computer. Xi-Series,%20Merlin%20ISP-100.pdf
