Just beginning the project, but I have been working with Rick on a L/C/R setup to go behind an acoustically transparent screen wall. I am currently using Jim Holtz/Curt Campbell statements V1 mains and a Statements V1 center channel. If you're familiar with these speakers, they are a very large WMTMW design for the L/R and a large 3-way center channel that all use variations of the Dayton reference aluminum drivers, Tang Band full range 4.5" midrange, and the Fountek NeoCD3.0 ribbon tweeters. I have been very happy with these speakers for both music and movies for the last 7 years. I cannot recommend them enough for a relatively affordable high performance DIY speaker with great dynamics, clarity, and top-to-bottom coherence.
My situation will be changing and I will be moving to a new home where I have an opportunity to dedicate a space to a music/home theater with an acoustically transparent front stage. Hoping this will be the last and best setup, I decided to go all-in with a Selah design as I've always wanted to take advantage of Rick's crossover and design expertise with high-end drivers. The requirements that I communicated to Rick were: Dynamics for reference level music and home theater, ability to use the L/R without a subwoofer for music, bass extension that could cover any music, and midrange/treble that equaled or exceeded the Fountek ribbons. I also wanted to use identical speakers for L/C/R with the center being located behind the screen.
After a number of productive conversations via email with Rick, he suggested the new Illuminismo kit speakers to achieve the goals I requested. Rick has been great to work with and has been extremely prompt and thorough when communicating. So yesterday, I received part of the Illuminismo L/C/R kit and the balance is on the way this week. All SB Acoustics Satori drivers in a large MTMWW arrangement. Check out the kit page for details.
I will try to document some of the build on here, but I cannot promise a timeframe with work and family obligations (and a torn rotator cuff!). I will however post pics as I can and will certainly provide some impressions once they are completed since this is a newer design based off the discontinued RC5. As a teaser, here is the "waiting to be launched" section of my office.
