Open Baffle Opinions - I Won't go back to Boxed Speakers Evr Again (maybe....)
https://photos.app.goo.gl/cg64ScibP75b1YVF6
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 added a side panel (behind the baffle) on both Speakers facing inwards to each other with acoustical foam. 10° of toe in and the Phantom Center is back baby ! It's not razor sharp but it's better than it was yesterday. The Treble is a bit subdued now. But that's to be expected. My ears will adjust. To me when someone says the Treble or the Speaker has lots of air, that's a hot Tweeter. This is great when you want to hear the Fart of a Knat, but to my ears it can be fatiguing. No Tinnitus here, just 51 1/2 years of age. So long as the vocal sibilance's stay dead center along with the Kick Drum & Snare Hits, I'm good. I have some mono DSD files legally purchased/downloaded and will try them out tonight. Right now, it's a 70's Vibe, CSN, & Y, The Eagles, James Taylor, Joni Mitchell, Carole King, and whatever else I'm either Streaming (AmazonHD/Bluesound Node 2i) or Spinning (SACD/CD). Thanks for all the encouragement and advice folks. I still have tinkering/tweaking to do. |
