Just for fun...
Building a pair of Linkwitz Orion v.3.x.x speakers kept me busy all through April this year. I had bought parts all the way back in 2007. Talk about procrastination!
The project was much more difficult than I'd first thought. Between cutting the multiple curves on the plywood, the no-screws midrange mounting (to prevent transfer of vibrations into the baffle), sourcing odd parts, the painting, multiple layers of clear-coat, endless sanding, & finally wiring 8 thick cables to 8-conductor Speakon plugs & jacks -- it took me over a month working nearly full time! Admittedly, I'm not an expert woodworker, and I did want the end result to look good. The most elaborate & complex audio DIY project I've done -- even though I was working from plans and a guide. There are lots of details that need to be finessed. I'm pretty happy with the end result, both visual & aural.
My experience with these speakers (version "+" w/ Linkwitz supplied electronic xover) has gone something like this:
1) excitement & relief at finally completing the damn things & hearing them at last!
2) delight at the big sound, obviously broad bandwidth, and great dynamics -- combined with dismay at an oddly "horny" midband (vocals, etc), heavy midbass
3) extended fine-tuning with positioning & active crossover driver levels resulting in much better tonal balance -- but still feeling the need to tweak JRiver EQ controls to compensate for better/worse recordings (especially the worse ones as the speakers seemed mercilessly revealing)
4) room acoustics compensation applied with software & multiple freq response tests at seated position with lab quality mic & associated gear...
5) ...resulting now in just about the best canned music I've heard in 40+ years of high end hifi experience. Extremely transparent, tonally accurate, very dynamic, not just a window to the music but an open garage door. I rarely feel the need to adjust tonal balance for bad or odd recordings now.
