mkay, all other mfg's can now find another business, tc just owned them

There's lot's of great looking new toys. I was just surprised to see assembled loudspeaker systems.

And yes the 'pro' designs with their Neo motors are very intriguing. The frame design is the one used for the original Stryke HE15.

Yeah, I'm with you there. I can't help but think something will be wrong with them (aside from the price). With a 4" VC the inductance is gonna have to be high. I can't imagine the power that thing is gonna have to make to have a high efficiency with aluminum cones. I wonder if they are putting any copper in the motor? I can't wait to see what they test like.

BTW, here are some 'spy' photos from TC sounds

That driver is an evolution/response from/to the original Aura 1808 drivers. BASSMAXX has used them or similar drivers at various times and the driver shown is used by WorxAudio in their big, vented pro-subs.

While I know there are various implementations, I know that some have been underhung, which does help keep the Le reasonable with a 4" VC that has lots of Xmax. Very interesting stuff.

Good catch....:wink:

Here's a pic of the 1808 for the new kids that don't know want it is......

That's just sick...

[Jack Gilvey]

Nice stuff, it'll be interesting to see some real test results on them.

[AJINFLA]

Yes, the Neo motor is nice, but the combination of highish efficiency, high xmax and aluminum cone makes me believe that the speaker gods may be listening to my prayers. Pro units and pistonic cones = oil + water.. until now.
I had to search the ends of the earth to find a metal cone pro mid, but this gives me hope that we may be (finally) heading in the right direction for dynamic driver design.
If the recent rash of new coaxials weren't enough and now this. Very cool....for me at least :T

lol, no. Just the sight of drivers with bulletholes makes me a little sad inside, thats all. :T

ah, now I get you

[ThomasW]

That's no less than $1000 worth of Eclipse drivers...

Hey guys,

Those are our newest pro drivers, we recently increased the amount of neodymium in that motor by two fold for a lot more Bl product and efficiency, and yes, there is copper too, copper is your friend, inductance and flux modulations are always difficult problems when designing drivers, things we address constantly. Also (as of Monday) put a new voice coil inside that puppy. Yes, its under hung but it has a titanium former to eliminate resonance and eddy currents and it can take a great amount of heat without damage, three very common problems with coils, especially in high efficiency applications, and especially especially when you are horn loading a driver which this one can be used for. You would be amazed at what kind of anomalies are revealed in a horn loaded subwoofer.

Our new site is still in beta phase, I have already found a few spelling errors, and its embarrassing, I did the new site myself so I take the fall for that, I should have all the rest of the content in there within the next few weeks and it should be rock solid.

As far as line source goes, well I don’t want to give too much away, but as shown in the site, we will have 7+ foot tall neodymium ribbon tweeters inside that speaker. We will sell the tweeters on our site for DIY purposes, but I can’t give a timeline. But yes, these are 7 feet tall with no breaks, not individual ribbons. We will also have shorter and taller versions too.

The speaker in the picture is one of our prototypes, actually that’s a rendering of it I did in 3D Studio Max, but it looks the same as the original speaker which was not available for photography because the pair was stolen by our CEO. I gave Thilo crap the other day because he took it home and I kid you not.. The first movie he watched was Brokeback Mountain. I mean common, I would expect nothing less than Jurassic Park or Star Wars with special effects galore and he pops in the Brokeback DVD, lol.

Mark: I’m loving the renderings of the new BMF on the av123 forms, that thing looks to be downright awesome and I'd love to own one. Best of luck!

worx is a bit different, can't really talk about it, but I love that speaker.

Very impressive description, but where are the spec's?

[Mark Seaton]

They (WorxAudio) only sell the driver in completed, pro-sound cabinets, so for them, the specs don't matter much other than what it does in-box.

I love it, I can deal with the price if you're making something outstanding. This sounds outstanding. :T What kind of efficiency neighborhood are you in?

Hehe... saw a few typos. I figured you guys were up late doing the site.

I never pictured Thilo as a 'cowboy', but he probably looks great in chaps. :B

Good luck on the new lines.

[Amphiprion]

I am most excited about their higher efficiency LMS drivers that will be coming out, their pro drivers, and their upcoming line of passive radiators (as confirmed by a TC rep on avs).

The PA3200 listed power handling as 1K to 20K... that should be REALLY loud

Patented?

On this page:

http://www.tcsounds.com.unixweb-7.n.../tcproducts.htm

Text reads:

"Our brand new LMS Series subwoofers take advantage our or new and unrivaled patented linear motor technology."

Is this technology really patented, or just patent-pending? If the later, this should be made clear.

Naultilus (the exercise machine company) was recently held liable for false advertising when it claimed a part was "patented," when it was not:

http://tushnet.blogspot.com/2006/04...rtising-of.html

The patent law providing for fines for false advertising and marking:

I'm not a lawyer, but a technical guy with a pet peeve for incorrect patent advertising.

[oxcartdriver]

From the TC sounds web site:
The LMS-4000 borrows our robust TC9 motor and takes advantage of our new and revolutionary Linear Motor System technology (Pat. Pend.)

Karl,

Pet peeve or not, email or PM's are the proper method for addressing this type of question...

[Jack Gilvey]

I'm trying to model the TC-1000 12" SVC but the Unibox-derived specs don't jive with what they list, it also appears to need a huge box for maximally flat. Can someone check it for me? This is what i got from their page:

12" TC-1000 SVC
Qts 0.470
Qes 0.515
Qms 5.308

[Jack Gilvey]

This driver is the ideal candidate for anyone looking for powerful clean bass with suburb quality for either the home or mobile environment.

I wonder if the inner-city model is tougher...

[Mark Seaton]

Do note that Cms should be 350um/N, or 0.35mm/N. They forgot a micro prefix.

I haven't modeled that driver yet so can't comment on much more.

I was having the same problem with that 12" TC-1000 in unibox. It was suggesting a 6ft^3 box for a Qtc of .7, IIRC.

[Dennis H]

The Vas and Cms aren't internally consistent, even with the missing micro character. I suspect the Vas is way too big, which would give you too big a box, but who knows?

[Jack Gilvey]

Yeah, Vas might be the culprit, we'll see what TC says. It came up in this thread from their forum , and they were going to look into it.

While we're here, what's the difference between Res and Rp, and between Ls and Lp?

[Hank]

we will have 7+ foot tall neodymium ribbon tweeters inside that speaker. We will sell the tweeters on our site for DIY purposes, but I can’t give a timeline. But yes, these are 7 feet tall with no breaks, not individual ribbons. We will also have shorter and taller versions too.

THAT got my attention :B How will the pricing compare to the B-G's sold by Parts Express?

Interesting sub drivers - should be some good IB applications in that lineup.

[Dennis H]

THAT got my attention :B How will the pricing compare to the B-G's sold by Parts Express?

Yup, that's quite a teaser. Everyone wishes they could buy the long Maggie true ribbons but they aren't for sale.

[Scott Simonian]

A much needed...bump.

[Jack Gilvey]

Well, since it's bumped, I did get a response on those specs for the TC1000 12" SVC and it was the Vas that was off:

Res = 4.235 Ohms, DC resistance
Ls = 2.043m H, series inductance
Lp = 1.844m H, lossy series inductance
Rp = 2.374 Ohms, loss across Lp
Dia = 250m meters, effective
(%shift) 33.8 %, resonance with mass
Vas = 118.5 litres, air volume equivalent
mms = 168.6 grams, effective mass
cms = 350.3u m/N, compliance
