I suppose if you put a modern flyweight amp into a chassis machined from something heavy it might be convincing. Many of us came of age pursuing audio gear with beefy transformers. Weight was a proxy for build quality. FWIW - I was on the fence until my JBL 708p arrived, in all their Class D...

I'm having a rudimentary concept problem: each membrane is driven from two "corners" in the array? How does this avoid bell modes? I would be very curious to see efficiency figures.

What little I know came from building Troels Gravesen's designs. Note that crossover boards need not be all on one "plate" as the signal feed wires, or serial connections can be used to span more than one backing plate. It has been my habit to install crossovers first and leave the driver...

What's the seating distance from the screen (which would be in front of the array)? This looks like a fairly standard movie theater layout.

Never warmed up to my F2, I always preferred something smaller. The Leica M3 was my "everyday carry" in the 1980's. Paired with the Summicron 35mm f2 (what I could afford) it was excellent.

What are they like, if they are aligned to cross in front of you?

Elmer Bernstein gets my vote.

Good idea.

I had a set of Definitive technology floorstanders that were bipoles. My dumpster salvage MMG were better. (Corrected Bipoles)

A dipole radiates equal amounts of sound pressure to the front and back of a listening space, regardless of enclosure design. This limits sidewall interactions and can create a secondary wavefront. If positioned correctly in a room, this can offer an audible signal that emulates the way live...

Certainly this bears further examination, under the standards accepted here at ASR. Your attitude, however is a bit "Dutch" for my taste.

Ex-scrabble, maybe.

The 405 is a dated design. I would not recommend the original, let alone a copy.

The Klipsch design requires little power but is very sensitive to noise. I have fond memories of the Unison line, which was solid and quiet. https://www.hifidiprinzio.it/en/amplification/integrated-amplifiers/unison-research-unison-research-unico-secondo.html If available second hand, the...

Where are you on the planet, Giuseppe?
