Open Baffle Opinions - I Won't go back to Boxed Speakers Evr Again (maybe....)

My very last DIY effort after doing the DIY Speaker thing (for myself only) for 35 years (only 5 pairs built in that time). These are my best effort WRT to sound quality. Bass down to 30Hz, sweet treble and midrange to die for.

All Parts Express Drivers. GRS Planar, GRS 12" (Qts = 1.27) Woofers, and Dynavox 5 1/4" midrange/midbass Drivers. All in $600. Still some tweaking to to on the Cabinet and the Crossovers. A simple 1st Order 16uF Sonicraft Capacitor on the Tweeter and a 2nd Order Bandpass on the 3 Dynavox Drivers. The H-Frame Woofers section is powered by an ICE Power Class D (1000W@4 Ω). Two for stereo of course. MiniDSP dialed in for a 250Hz Linkwitz-Riley 4th Order LPF, the Bandpass is 250Hz - 2500Hz, and the Magnetic Planar BG knockoff by GRS takes over at 2500Hz. No L-Pads anywhere !

My question is what is the Phantom Center like ? Mine is not as focused as I’d like it to be. But my God, the soundstage, imaging, front to back depth is amazing. Clarity like I’ve never heard before form a Box Speaker and the Bass is like I’ve never experienced. No Box Boom. 40Hz all Day and I can hit 30 Hz with very little attenuation

I agree with the OP. Once you’ve experienced OB’s you’ll never listen to a box again. Fact is, my first set of speakers were boxes but featured a Heil AMT. I enjoyed them immensely. Since 1980 I’ve owned electrostatics. In 2010 I discovered OB’s made by an audiophile whose main gig was producing 30’ boardroom desks here in Seattle. The man had serious woodworking skills, and his OB’s were sensational. He began building speakers which had a following. He built the Hawthorne Rainiers which featured a huge Heil version in their center. For woods he’d use Sapale or the finest Birch you’ve ever seen. I owned two different pair over the years which featured 15” woofers. It’s the finest natural sounding bass I’ve ever heard. Yes, once OB, never back. Fact is, there’s a ton of OB options nowadays.
