I would definitely find one you can demo. IMO they have a really nice sound, but it’s definitely a little different than other options out there I think.

I've made some good progress. I finished painting everything and have installed everything but the back two surrounds. Just have a little left to do on them. The paint turned out great on all of the speakers. The L/C/R in black have just a little more texture than the white subwoofer got. I just used a Wagner Flexio 3000 sprayer from Lowes. Once I learned to thin the paint way more than would seem right, it sprayed really well. Almost the consistency of water. The PPG Breakthrough thins with water. It can be recoated within an hour so depending on temperature and how thick it was applied. After a few days it is very hard, but hard enough to work around after a day or so. I'll get some close up pictures some time soon.


So far everything sounds really nice, and very clean and crisp. The overall power is a little underwhelming though, so I need to triple check for leaks again and make sure I have all my settings right. Any ideas of what else to check? The other BFM system I listened to was punchy and tactile. Mine will get loud but its just not as bold as what I listened to. Im Running a Denon X3400H with Audyssey XT32. I think I did an ok job on setting that up, but I'm also sure I have some to learn about it still. Maybe that's where some of my issues lie.


The side surround speakers work extremely well. I was surprised at how nice they sound and how loud they get considering that they are in an undersized enclosure, and they only crossover they have is a cap for the tweets. The are about 8" from the ceiling and pointed up (constraints of the room and the wife). This does work for surround sound but adds some odd imaging at times since everything is way above ear level. Not so bad I can live with it and be happy though. There seems to be a lot of high frequency content on those channels that I never knew was there. Maybe I can unsolder the tweeters and make those channels more vague.

Very nice. I wish the tweets were better quality, many came apart on me. I would find the magnet structure on the bottom of the cab or hear a thunk when screwing them in. The glue was not very good on many of them. I guess a bad batch? I believe I have enough drivers and tweeters for 3 more TLAH. I am using my left over upgraded drivers first. So far I am finding that Dayton woofers and tymphany tweets are the best.

Now I'm super nervous. I had 5 tweets that were broken when I got the shipment. They were crushed, but didn't have any with magnet separation. Leland @ Speaker Hardware, sent me 5 to replace them, and the magnets fell of in my hands as I pulled them out of the package. He is sending 5 more, so hopefully this will be a different batch. I think the first ones I got will be ok, as I didn't have a single problem with 37 of them. Even the ones that were crushed, the magnet is still stuck on well. With 41 of them on this build, it would really suck if they started falling apart.

That picture that says "Christ" needs to be changed to "Christ!"

I wonder how much dispersion that center channel has compared to a 15" wave guide.

Looks awesome!

I assume the opening of the sub is pointed at the wall to the left in the pic? Although not as symmetrical, if you move it closer to that corner, you will get a little more room gain and extension.

However, I bet the loss is in the calibration. Are you using the Reference setting in the Audyssey menu? I run Reference and usually bump my amp knobs up a couple of clicks to suit the material and my personal bass tastes

That front wall came out looking great! Again, great choices on drivers and colors there, it came together in the best ways!

I’m not familiar with the wave guide. I don’t have to blanket a very wide area but the curve array covers it well.

You can go into the subwoofer distance setting on the denon and add distance, from what I learned with my setup maybe start with adding 4ft. Sometimes there can be some cancellation between the sub and speakers and adding distance can help take out a massive null if there is one, its typically around the crossover level.

A umik1 and REW can help you understand exactly where your issues are though, weather its midbass or low end, or across the board. But Like alot of people can already tell, while it looks the best, that positioning isnt the best for sound.

Thank you sir. Mouth of the horn is actually pointing at the wall under the screen. It’s only about 4” away and I wonder if it’s oart of the problem. It turned out larger than my wife though so putting it in the corner might be of benefit anyway . Isn’t there an optimal distance for it to be from a corner wall?

12-24" from wall works good. 18" is best.

AVR sub Distance should be approx 12 feet further than the actual distance. Auto calibration will account for this if you're using it.

@Samps nailed it. You are certainly losing out by having that mouth nearly covered. Once you get it to an optimal location, you will have to calibrate Audy again to set the responses and distance properly.

I’m sure it’s probably in the worst possible place since that’s how it usually goes. I have the umik and rew but need to do some serious reading since I’m not really sure how to run it correctly and then interpret the results. I’ll try fudging the distance and see what that does.

"You can go into the subwoofer distance setting on the denon and add distance"

there is also the "Sub Distance Tweak", which initially says to change sub distances equally, sometimes more, or less

however, in a different room -YMMV - and so may the distance changes

in my 10ish x 10ish mancave,

a few thrilling and productive hours of REW got me this improvement . .

Auto cal must have done just about right, it put it at 27’ and my center at 15’. I’ll try 18” in the corner. Should I put it 18” from both walls or just from one of them? Not that it should be a big deal to test both ways but this thing weighs as much as a tank!

Ideally you would have the sub right up against the wall (closed side) with the mouth (opening) pointed at the adjacent wall 18" away.

If that won't work in that room, you can try placing it behind your seating with the mouth right up against the back of the seats. Maybe leave a few inches of breathing room.

I used 10db offset until I went with a house curve in the inuke amps dsp.

Yeah, Leland took care of me as well. I still have a box of 53 of them sitting here. They sound great, but build quality is terrible on the tweets.
