FINALLY... I'm getting to work on my 'parts bin' Osprey-BR. I installed the CDs in the woofers and mounted them in cabinets from a pair of Klipsch KG52, which are about 2 cubic feet (56 liters) in volume, one foot (30cm) wide baffle, 12.5 inches (32cm) deep, 37.5 inches (95cm) height.
For now, I'm going to mount the crossover parts externally, on a board, so I can modify parts as needed before finalizing.
I'm a little worried about baffle step effects from the skinny baffle causing a mid-boost. An app called "The Edge" calculates I'll get a boost around 550Hz. We shall see...

The crossover boards are UGLY, because I had to parallel smaller value capacitors to build up the needed crossover values. But I now have both speakers playing. I've only listened to the speakers driven by my old Panasonic AVR, but I know that sounds acceptably good, so I believe it's a fair test.
First impressions are:
Thanks for the great design, Michael!
First impressions are:
- Very sensitive/efficient. It takes very little power to get LOUD.
- Detailed. Lots of clarity. I like that.
- Voices on TV sound very 'live' and present, without a metallic 'sheen'. That's tough to do, because TV sound mixes are usually really hyped up for vocal punchiness and dialog clarity.
- Percussion and drums sound amazing. 'Fast', punchy, dynamic -- yet delicate when called for (triangles, cymbals).
- Light in the bass, but there is bass there. It is a 'lean' balance right now. I will need to work on the cabinet tuning some more.
- DYNAMICS! When something is punched up loud in the mix, YOU KNOW ALL ABOUT IT.
- Imaging is getting more stable the more I play them. I think they're actually breaking in.
Thanks for the great design, Michael!

I'm curious about building one of his bandpass subs to pick up the real low end.
Fast, punchy and dynamic really does sum up this speaker well.

I'm not sure if I did this right but here is what I get with REW with the mike right even with the edge of the speaker.
any idea why there is the drop at about 600? Is it normal or did I just do the measurement wrong?
The 'official' one doesn't show a dip there and mine also tilts up more above 10K.
