So it would cost about $900 just for the drivers and crossovers to build a pair of surrounds?

Consider another $100 at WORST for materials and you have a pair of killer surrounds for around the same price as a single slanted8 biggrin.gif

All right now you're speaking my language! Hurry up and get this project going!....LOL

I have a buddy that's an unreal painter, he does customer stuff for the motorcycle industry and is willing to put his magic on some speakers if I build some. Probably cost me a case of beer.

A case of beer is my kind of talk! haha. I have done many a job being compensated by some hoppy goodness.

Bumping the thread for some good news.

The first coaxial kit is complete and it sounds great. MTG90 and I messed with some expensive coaxials, cheaper ones, and different compression drivers. The end design might surprise you. It uses the 10" Eminence and works well in a very small sealed box, small ported box, or even a ported tower that you could nearly call full range. We've built a couple boxes and put a lot of power through each one and they all passed the test. For the past couple days I've been running it full range in a short ported tower and it's pretty crazy how much volume even a single one of these can put out. And it sounds clean and smooth doing it. Easily plays at high enough volumes to be used for main speakers in a large home theater, let alone surrounds.

Efficiency is in the mid 90's.


Price?

I don't know exactly what the flat pack cabinet will cost yet, but I do believe the entire kit should come in around $155........with the smaller flat pack!! biggrin.gif

That doesn't count shipping though. I'm hoping to get everything together and try to figure in "free shipping" for around $170, $175 or so with Paypal fees, packaging material, etc. I'm not sure how much the package will weigh with the flat pack yet, but it should be around that price.

Wow, awesome!! I'll definitely be buying some of these.



Which CD?

This is the best news for new speakers I've heard in a long time. Any ETA on ordering? I'm pretty confident I'll want 4.
post #340 of 867
Wow. Awesome. I'll be in for a pair as soon as they're available. Thanks to all who contributed!
post #341 of 867
I will definitely be up for purchasing several of these!

Erich, did you guys do any comparisons with the B&C 8CX21? I wonder how it would compare to this 10" Eminence?
post #342 of 867
Hey Erich,

How small is "very small sealed box"?


Cheers
post #343 of 867
This should probably get its own thread - but PE says the Beta-10CX has F3 of 103 Hz in 0.56cuft. I assume that's the driver in question, and I would bet the volume is a hair more than that.
post #344 of 867
The small sealed box would be about .6 cuft. You can't always go by those numbers on the PE website. Sometimes their box calculator puts 15" woofers in .5 cuft boxes. I think it's just an automated program they use for each woofer model.

We didn't compare it to the B&C 8" coaxial because there really wasn't much reason to once we got done with the 10" Eminence. This speaker sounds great, meets the price point, puts out plenty of volume, and can be used sealed, ported, for surround duty, and even full range. And to top it off, the drivers, crossover, and the flat pack will sell for less than the smaller B&C. And I doubt it would be better anyway.
post #345 of 867
Any angled baffle on these?
post #346 of 867
Depending on when they are avaialable - sign me up for at least two ...
post #347 of 867
Sweet! Merry Christmas to me!
post #348 of 867
wow...great news. I'd like to replace four 8" ceiling speakers with these. Any ideas about off-axis response? I could build these on an angled baffle recessed into a box in the ceiling to get some angle, if necessary.
post #349 of 867
Awesome. This is the news I have been waiting for. I can hear the christmas jingle in my head singing - "Merry Christmas to me, Merry Christmas to me"
post #350 of 867
Maybe I can get a few box designs cut if that makes any sense to do.

One would probably just be a 12" cube. Or maybe one that was a little taller and shallow.


If anyone wants an angled box, I'd need the dimensions. I have no idea how much extra a box like that would cost because mitered angles would need to be cut on a few pieces after it comes off the CNC machine.
post #351 of 867
not that I'd expect a premade box that would work for a ceiling mount, but something like this for those of us without walls to mount to would be awesome.

This one!
post #353 of 867
Erich, do you have a time table as to when these will be available in flat packs? As soon as they are done, I will immediately be ordering a pair. I still have two of the B&C 8CX21's that I will likly build to compare, and will probably use one pair as surround rears, and the other as side surrounds!
post #354 of 867
It would be good to figure out the shape of the box first so I can get them cut.
post #355 of 867
Hi Erich,

What is the driver depth on these?

Thanks,
post #356 of 867
I read 6.5" including the CD mounted but don't quote me on that.

Yep, that is wonderful! Which CD did you end up with and do you have any sweeps for it? In 1 cuft the f3 should get you down around 80hz sealed, which is about perfect for surround duty. I have to agree the emminence is solid and has crazy output. Maybe people will start to finally see what I have been enjoying for so long. I would love though if you or mtg90 would shoot me the CD you used as well as the new XO network so I could A/B it with the selenium and with the APT-50 to see how they all stack up against each other. Are you game for that Eric?

YES!!

My reaction:
post #359 of 867
Are 8" models still a possibility with this news?
post #360 of 867
Thread Starter 
yes, I still plan on doing the 8" beyma model, but it will be significantly more (probably double) that of this build, but should yield some excellent results as well. Had some random expenses come into play that have significantly hindered my order on them.
