Oh yeah, can't wait to hear about the Beymas.

Haha, the candle is my last remnant of Christmas still laying around. Can't give up that sweet sweet frasier fur smell just yet smile.gif My trees sucked this year and didn't get the fragrance around the house very well.

Depending on my results, and how well I feel these perform (I am very confident here) I will start working on slant style boxes, up until the point that Erich might offer them. I will get more pics once I drop the beyma in my emmy box, but the same form factor is what I hope to accomplish in the end.

You worked fast on that! Did you notice how the flat packs went together better than the last ones? I had the second round of those .67cuft boxes cut with wider rabbet joints so that any slight thickness variation in the Baltic didn't cause any issues. How did you like the crossover board?

When you get those done and slightly broken in, you have the thumbs up to REALLY crank them up loud. If anything pops, I'll send you new parts. biggrin.gif

Guys, sorry for how long it took to start shipping these out. I got bogged down with things in the past 2.5 weeks and it was hard to get caught up. The group buy on the Anarchy, and shipping container with SEOS waveguides has been a lot of work.

These will be finished just the like Fusion 8's i did (see my build thread) Duratex front and a stain+gloss finish on the rest

TBH they went together fine, i didn't have any issues with the other ones so its hard to say if it was better or not. crossover board was pretty nice, only noticed a cpl things with it. Holes for the iron core inductor are not labeled. but are obvious as they are the only 2 free ones with everything else in. The lead wire on the inductor almost didn't fit through the hole. no included schematic (some may want it)

I didn't include the schematic for the 8" model because the parts are drawn on the board and the 2 resistors are the same value. So I don't think they can be assembled wrong.

I did notice the holes for the inductors are a bit close. They fit, but can be drilled out with a tiny bit if needed. I was assembling a different crossover and decided to drill out the input holes a little bigger to use some larger wire.

If you think it's necessary, I'll try to get those holes increased in size on the next batch.

Erich with the amount of work you do for the DIY community I don't think you need to apologize for anything.

yea id increase the size of the hole slightly, reason being 1 wire on the inductor is always a bent mess. the one that is nice and straight goes in fine, the other not so much

Yeh I do. No one wants to wait 2 weeks or so for audio stuff. There are changes coming though, so things will get better.

Yeah I had to wait three weeks for a center channel that I a getting cheaper then I would from parts express ... that will crush my previous speaker . I am really getting shafted eek.gif

Erich ... the only advice I could give you is to let people help you when they offer. I am a teacher and for years I would go in sick to work thinking I had to be their. You know what I found out when i booked a toc ? The world goes on. Yes sometimes they mess stuff up.. but often they do just fine. Keep up the great work smile.gif

The main thing I do is package stuff up and try to organize what's coming in. Sadly, there aren't many people that can come here for a day of help and know how to package up a pair of Fusion-12's. smile.gif

I'm hoping to stream line things in the next few months and get it running smoother.

Either way, back to the coaxials. biggrin.gif

No you have two IPR's. one bridged per driver. That outa do it smile.gif

Just kidding, I know the IPR's don't bridge. so one per channel should suffice for now...

I am sure they would sound awesome with more power. Not sure if anything more than 1000watts will be a difference. I have my 80watts rms SLA's on 1500watts power amp. They sound MUCH better than my 110watt AVR.

They are more likely to sound better from above or below as well as from off to the side, because, well, they have no top or bottom. Great choice for surrounds for that reason.

Lol...something like that. Otherwise referred to as "dispersion pattern."

Coaxial defined means, "mounted on a common axis."

The beymas, for instance, are a two-way coax design with a compression driver mounted to a speaker to cover more of a broad frequency range from a single point. This wiki article breaks it down in more detail if you want to look into it further.

I don't have the $$ right now for any of the JTR surrounds, but if these could keep up they would fit nicely into my budget.

You are taking this to the GTG this weekend right?

3 - JTR 228's LCR (game room)
4 - DIY Sound Group V-8 Coaxials in slanted boxes (game room)
4 - PSA Triax's (game room)
3 - DIY Sound Group V-8 Coaxials in Ported Boxes for LCR's
2 - SVS SB13+'s (living room)
1 - SVS SB12-NSD (bedroom)
