Over the years i have built several home systems, including amps and speakers. This, at least for now (what isn't) is the fruition of all that work.
Twelve months of careful, sometime spainstaking fabrication. It started when i had the opportunity to visit Mr Linkwitz and hear first hand his Orion speakers. I have been fortunate to hear many great systems, including Macs, Sonus and a $100k steinway, and to my ears this was one of the most spectacular. Mr Linkwitz sells the plans to his system and warns that it is a serious undertaking but as my audition had demonstrated well worth the time and effort.
The system is comprised of dipole speakers, 5 drivers per channel and a fully active crossover. It requires 8 channels of amplification.
The primary drivers are seas excel with peerless woofers. I fabricated my baffle from reinforced CNC milled 1/8" aluminum plated. The sub section is isolated from the front baffle with neoprene and spacers.
I understand the tendency of owners to wax lyrical about their own gear, the DIY kind, but in all honesty, in terms of speakers and amplification I am extremely happy with the digital front end. The Benchmark DAC is superb, all the reviews and occludes are right on the mark. The Mac offers a great interface and ease of use.
The analog front end is more laid back. The channel separation is a little fuzzy. It may be the cartridge or the somewhat dubious Linn tonearm wiring which is something i need to investigate.
Thanks for looking and comments. I anticipate many, many hours of listening joy
System edited: Added VTI equipment rack. Follow my trails and tribulations as i attempt to remove unwanted foot fall from a rack mounted turntable... not pretty
Hi Gary, Nothing really special about these Orions except that they are the latest version which uses a rear firing tweeter wired in series to the front tweeter with a small resistor to slightly lower the output. The rear firing tweeter has its own baffle which is probably why from the image the baffle looks like a continuous tube. The image is misleading as the mid site completely free. Check out the following link to the build thread on DIY Audio:http://www.diyaudio.com/forums/multi-way/156315-orions-completed-aluminum-baffle.html One of the posted images is a photograph of the rear. The base unit goes low but is not a sub woofer, again it is two woofer wired in series with the rear facing back. The cabinet appears closed but the front and rear are acoustically transparent. Each channel is 5 drivers all configured to produce the sound of a single dipole speaker. The baffle is fabricated from aluminum plate, broken and milled. Let me know if you have any other questions. I would be happy to offer what help i can. Cheers Meil
