Just for fun I decided to build with only what I had at home. No going out for ANYTHING. Not even fasteners or wood (you'll see how strict I was about it below).
The baffles are 48" x 13" glossy white panels from the Ikea bargain bin a few years ago ($2.50 a pop - I couldn't resist buying 10 - these are the last 2). The woofers are some Eminence 12" prototypes I swapped for >10 years ago. The TS parameters are hand written on an Eminence label on the magnet. The upper drivers are some unknown pro-sound 12" coaxials. They look like B&C from the basket, but who knows. Also acquired via swap several years ago. Crossover is active via MiniDSP 4x10 and amplification is a Savant 8125 (8 x 125W/ch of class D). Blocking caps for the tweeters are a bunch of 10µF poly caps I bought a bag of some years ago. Here is the last 6. I had no binding posts, so I used audiophile approved wire nuts (don't laugh, they work just fine).
The woofers go 50-300Hz @-48db/oct, mids to 1.4kHz @-24db/oct, and tweeters also at -24db/oct. There are 3 subs sprinkled around the room for <50Hz duty. Plenty of PEQ is used. Some of which is due to the drivers and open baffle operation. Some is due to the room. Either way, it's EQed to about ±2db from 30Hz to 19kHz before my preferred house curve (which tilts down at 1db/octave from 30Hz to 9kHz then flat).
They sound pretty nice. Lots of slam from the big mids. No bloat from the OB bass. They can play much louder than I can tolerate. Brass/horns sound very nice, but I've heard better cymbals. Also imaging is not fantastic, but the room and OB aren't helping here. They're fun, so I'll keep them for a while. I have more drivers around, so I'll probably knock something else out this summer.
In storage
I have a pair of:
- JBL 2217
- Dayton PS220
- Celestion 5" mids (whose model # I can't recall)
- Dayton PT2 planar tweets
- B52 PHRN-1014 waveguides
- Several misc tweeters of unknown provenence
So maybe a JBL L100 revisit with the 2217s, Celestion mids, and whatever tweeter works out (the Celestions are pretty flat out to 6kHz, so a 2.5 to 3kHz XO to the tweeter makes life easy for the tweeter). Or maybe I'll bend my rule and get some CDs for the B52 waveguides. Who knows...
