My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Romy.
The Dannoy's are the main left and right front speakers, with self built Edgar horns for the side and rear speakers, and various cone speakers for the 7 overhead channels. Each floor horn has a separate subwoofer, with two extra subwoofers for the subwoofer channel with 4 12 inch drivers each.The sources are an OPPO BDP 205 4K disc player, a self built computer for my 8 terabytes of music and movies, with the music from cd's my vinyl processed to 24/96 and about 300 15 ips analog tapes from 2nd or 3rd generation master tapes from major studios transferred to 24/48 files, and Apple, Amazon fire and Roku units for television and streaming. All of this is controlled by a Trinnov 20 channel preamp processor, which does dsp speaker and room correction, and now as the crossover for the Dannoy's. The Dannoy’s are crossed over to a pair of JL audio f113 mark 2 subwoofers at 60 HZ.
Over the past three months, following Romy's advise, I have purchase two sets of tannoy red 10 inch drivers, the best two in the Dannoy's, and two Yamaha B2 amps from Japan, which use vfets, which have the advantages of both tubes and solid state output characteristics. So the system is a combination of 30 year old speaker and amplifier technology run by the latest and greatest digital signal processing, with relativelyy inexpensive wiring, most of which high Enders would laugh at.
Over the past three months, I have experimented with various iterations of the Dannoy's configuration, adjusting the stuffing, positioning, tightening the driver's various screws, which were loose giving a subtle distortion to the sound, but especially the various crossover options. Thes we’re using two different sets of the original tannoy crossovers, a set of new passive crossovers from England, and finally using the crossover potential of the Trinnov preamp processor. While I have not been able to obtain the sound which so enamored Romy at his place with the same speakers, using the Trinnov crossovers, I have obtained what I consider to be the best sound in my room in 40 years. Using just the DANNOY left an right channels, the sound on the best recording fills the front third of the room extending beyond, behind and in front of the speakers with a clean and full sound stage. When I turn on the surround channels, the room fills, especially with 5.1 channel surround recordings, and when using AURO 3D processing. With the lights out, on a very few great recordings, one can really feel one has been transported to the original concert hall.
For the first time in over 40 years of experimentation, I am actually satisfied with the sound, and am afraid to change anything which may damage what's been obtained. So kudos to Romy for guiding me to this point. Now all I have to do is figure out how I'll break down my 50 Hz. Horns filled with 500 lbs. of sand without damaging the sound.
