Just a quick update: speaker for the show in final stages and to be packed and shipped from early next week to Dallas.
The backplate in video if anyone has noticed does not require AC. We will have both regular and new backplate at the show.
Please note – it’s not a replacement, it is an option. Look forward to comments and questions.Sharing the room with LTA and they will have the usual suspects:
AERO DAC, MicroZOTL preamp and ZOTL40 REF+monoblocks.
Dr. Vinyl I believe will have DS Audio (grandmaster EX)-
Can you explain how the new backplate works without power to maintain a charge on the panel? It definitely has the benefit of convenience.

Very nice to have your question … I hesitate to post too much because sometimes only feedback I receive are to ‘be quiet’ and really have no idea how many actually look in here.
Some details on the back plate:
1st – remember its not a replacement, it is an option.
Exceptionally convenient for export to other countries which require regulation/certification for products with AC input (cost/headache) also hopefully a very easy way to introduce to first-timers as they don’t have the knee jerk reaction when they see ‘another electrical device’ to deal with. And then also don’t need a separate power module for different voltages around the world so simplifies production. And of course easy to place in any room without a bunch more extension chords.Roger has devised a way to power membrane from the amplifier’s audio signal – initializing the charge to membrane when 1 watt of power enters back plate thru audio cables. It takes only 1/8 of a watt to charge. How much the panel needs is carefully controlled by the amount of power music is demanding and being pushed by the amplifier to panel using a very small percentage of that wattage. We will have both original and new back plates at the show so easily compared.

General invitation to Room 1201 at SWAF in Dallas this March 21-23rd.
Dr. Vinyl with LTA (and more details to come) will be showing.
A new (in progress) G7-7C Majestic will be at the show.
The room is larger than normal rooms (18′ x 20′) and also has slightly over 9′ ceiling.Things of note, a beautiful wood/grille combination – Maple with ‘Fir’ from Guilford (Duvaltex) photos attached.
Also of note: something rather special for backplate – an idea can be seen here on youtube. A huge step forward for convenience and ease of acceptance in general (we sincerely hope). More to follow.
