Don't mind the crap living room condition. I'm in the process of remodeling. Gotta love trying to refinish the space you're also living in... The equipment rack is being relocated once I tear out the closet door.
A few assembly updates. I went with stainless hardware for a little contrast. Literally zero finish work done, as I wanted to test everything out before I went through the trouble. No sense doing the finish work if I don't like the sound results!!! So the cabs are still covered in glue and haven't seen a lick of sandpaper yet. For scale comparison, that's a 65" TV.
you might want to adjust your CNC program for the woofer cutouts. The holes were fine but the rabbets were too tight to get the baskets to seat. I had to run through them again with a 1/2" rabbet. Only an extra 1/32" of material would have probably done the trick, but I didn't have the right bit/bearing combo to do that so I ended up closer to 1/16". It worked out though because the woofers now have a very slight gap around the basket to match midrange drivers.
I was originally thinking veneer but long-term I'd like to get these behind an AT screen when I move in a couple years (wasted work?). So now I'm thinking a 3/8" roundover on all the corners and take them to Line-X. And I still need to design/build grilles. Plenty of time to decide... Any other suggestions in this area would be welcome.
I'm powering these through a Marantz AV7702mkii Pre-Pro and their MM7055 5ch amp. So ballpark about 140W each. I suspect probably more like 125W each with all channels driven.
One thing I haven't talked too much about yet is the sub pairing. It's a 10ft^3 enclosure tuned to 20Hz, with 4 Hertz HX300 12" subs. Powered by 2 Crown XLS2502 running 4ohm stereo so I'm hitting them at approximately 800W each. I had heavily considered going IB with 4 18" drivers but didn't want to have to deal with putting the floor back together when I sell the house. They keep up with the 1299s just fine while barely clipping the -10dB light on the amps. I'll need to get the empty enclosure on a scale when it gets finished. I needed a dolley to haul the stupid thing before it even got drivers installed!
I was a bit scared to fire these up for the first time. I haven't had great experience with horn drivers in the past, so this was a bit of a leap of faith for me. I started with 2ch music as a baseline and then swapped to movies. A few thoughts:
* Audyssey clipped the output levels to -12dB and set Xovers to 40Hz. I had to boost the subs +12dB to blend properly. There's that efficiency for you!!!
* I was shocked to find how smooth the upper frequencies are, and how well the dispersion creates a 3D sound field. I had to check to be sure I had everything set to stereo instead of all-channel-stereo.
* High frequency smoothness is a bit of a double edged sword. I find myself cranking the volume because it just sucks you in, but you don't realize just HOW loud you're running it until your ears start ringing. I never thought I'd consider using the volume limiter in the Pre-Pro.
* I may need to throw a MiniDSP at this setup because Audyssey just isn't doing it for me. It's throwing some pretty wild correction curves out there. For the most part it's good but removed much of the lower end house curve and did some strange things to female vocals. I like to use Celine Dion as my female vocal benchmark, and Audyssey removed her room presence. Maybe the Audyssey pro-tune kit would do the trick? More data on this to come, but I think Audyssey just doesn't have enough EQ adjustment range to get everything right. Which is a shame because it otherwise does a great job of setting up a nice large "sweet spot" for the listening area.
* Movies have great impact. Subs could use a little EQ finesse but otherwise blend with the LCR beautifully. You almost can't even tell there's a sub in the room. (in a good way, as in the sub doesn't call attention to itself)
