These look quite nice ...

Wonder what the cost will be as their current 7.1R is $3k a pair!

Looks like one to me.

Wonder how "stable" those would be without being affixed to a stand or some sort. Hard to say without dimensions, but they do not look deep or wide...

Those look like the driver's Seaton uses in his.

With nothing to give it scale it is hard to say how large they are. They look pretty large.

They do look nice, maybe ~32" x ~12"

I'm guessing they're a limited bandwidth sub required type piece,..but who knows. I too am not familiar with the HF element. One thing I'm sure we can count on, the cabinetry is likely first rate.

I'm happy with a "sub required type piece".

Their 7.1 is $1200 pair. I can't imagine it's more than $2500/pair.

Dumb enough to spend lots of cash on this junk!

The woofers, it's safe to say, are 8" models. B&C and a couple others I think use those octagonal-flange baskets.

Hmmm ... wonder what makes the 7.1R's so much more expensive?

http://www.funkywaves.net/catalog.cfm?item=fw7_r

Outside of the 1" thick aluminum baffle that is. Don't know enough about ribbon tweeters and cross-overs to gauge the cost.

In any event, I love the high WAF of the black ones posted above.

That baffle can't be cheap to buy or machine.

And that speaker is also translam, which adds considerably to materials cost. As well as finishing time, most likely.

The new one looks like traditional wooden board construction, but with good attention paid to minimizing diffraction with large roundovers.

i wonder if this is the horn:

http://www.tradekool.com/selling-lea...-RT-62041.html



and my guess on the driver is the b&c 8NDL51.

the coax used in seaton's has the tweeter firing through the woofer. since this one has a tweeter, the coax would be redundant.

Listen. It's All Good.

Translam?

nice catch.

that does not look like a compression driver in that horn wi...more like a ring radiator tweeter. is that driver that different?

sure looks like one of these to me:

Those monitors are nice but not what I had in mind. Having recently talked to him regarding some speakers, he told me they plan on building a 2.5 tower version of the ht7.1 but right now it's not a top priority... it sure sounds like they're busy expanding the business.

And that's a good thing as the C to C spacing of the two midwoofers suggests a serious design flaw.

Can't you overcome phase and dispersion issues by using different crossover points for the mids?

That is not a good generalization. You do not know the XO point, the slope or the listening angle where the null is. Those will dictate if the C to C spacing is an audible issue.

The 7.R is expensive for a couple reasons, the biggest is the solid aluminum baffle, fyi they can be built with a plain wood baffle for $1000 less per pair. The enclosure is stacked laminated plywood, this used a lot of material and time to build. It also uses premium crossover components.

For the MTM we are basically done the crossover design and should have some final response measurements in a week or two, both on and off axis, in the vertical and horizontal planes, so far they are doing very well. The crossover point is ~1350hz. Overall size is 30"h, 11"w, 10"d. They are ported with an f3 of 60hz, they can also be sealed for an f3 of 120hz, f10 60hz. The tweeter is a Planar.

Price per pair is expected to be 2000-3000 depending on finish.

Here is a picture of the 8" mid bass.

Nathan,

Very, very nice,...is the HF element the Beyma pleated diaphragm/waveguide combo? If so, it's nice and very tightly controlled vertical,..almost line array like. Regardless which HF driver, this thing appears very nice.

I'm pretty sure that is not the TPL-150H unless they built their own waveguide. The screw holes are different. I doubt they'd use a $500 HF driver and sell them for only $1000-1500 each. The woofers are likely $150-200ea.

Yeah. Likely the same one Danley uses on the 3-way molded horns, and possibly elsewhere as well.

Yes, you're right,...the mounting holes are quite different. My wishful thinking perhaps. I'd love to see a commercial offering, or diy for that matter, using the Beyma design.

There have been several DIY uses of the TPL150 that I can recall. Dig around at diyaudio and some will pop up. Google too. Klang and Ton (IIRC) also did some measurements of it about 3 or 4 years ago.
