 Yes, a lot less

 

It won't use the variable resistive coil as that is not developed as a product yet but its a 3" coil, copper over the poll, larger magnet.

 Ahhhrrooo? Not variable coil? So is it not LMS tech anymore?

 

I'm cornfused. :P

 

Lol, guess I'll just wait til you get to play with it.

Dang Mike you don't miss much do you?

Scott I believe that Kyle meant that the coil will not be his new linear design from the patent application but will still be the current variable LMT coil.

Ah. Gotcha. Thanks for the explanation.

I had a bit of help, I probably wouldn't have heard about it as quickly otherwise, but I do pay attention to patents, as one can learn a lot from them. Also used to spend a LOT more time talking speakers than I do now. Was hoping I'd see Kyle's patent put to good use sooner rather than later, because it is a FANTASTIC idea. Simply put, Kyle has "fixed" several of the issues with LMS coil and motor. 

 

Hoping that we can see the state of the art take a step forward, and sounds like there have been a few significant steps with this one. Also thrilled that there is some R&D taking place at TC.

Yeah I am hoping Kyle gets his protoype driver with his new coil tech done soon so I can play around with it but who knows when that will be. I don't know I guess the guy is just lazy it's not like he has anything going on. :D This new 15" TC driver has me interested too...

 

Here are some of the things that are definitely getting tested eventually (That I can talk about. :ph34r: ). Some of these have been on the agenda for years...

 

Sealed JBL 2242HPL

25Hz vented AE TD18H+ Apollo

Sealed AE TD18H+ Apollo

MTX 9515-44 tiny passive radiator box with dual 15" VMP's (18 and 30Hz tunings to correspond with typical HT and car audio tunes)

Extra small sealed LMS 5400 Ultra and larger sealed MTX 9515-44 tests (to collect data to have directly comparable very small sealed and medium sized sealed for each driver and use to evaluate the effects on output, distortion, sensitivity, etc...)

LMS 5400 Ultra dual 18" VMP passive radiator system with 18Hz and 30Hz tunings

BMS 18N862 Sealed

AE TD15M Apollo sealed and vented (need to build a 15" enclosure for vented.)

 

Additionally there are some "special" projects of mine that will be getting evaluated eventually. I also have a number of raw drivers on my want list to look at.

 

As far as commercial stuff it is up to Mark, Tom and Jeff on the subs that everyone seems to wants to see the data for (Yes I do correspond with all of them).  I would like to get something from Danley eventually. I would also like to look at one of Rythmik's sealed high power 15 systems, more of the low dollar $250-$600 range subs and I want to look at the Klipsch SW-115 eventually too as it is going for rather low prices on the net and is a bit of an unknown quantity in the $650-$900 range. A THT, F20 or other of Bill's or LilMike's bang for the buck designs would be fun also.

 

I also have a number of investigative things I would like to do like measuring the gain of at least a few more vehicles and rooms and doing some distortion measurements with push pull drivers versus push push.

^  ^  ^

All good stuff there, especially interested in anything related to the AE TD18H+ Apollo

 

 

But this;

I also have a number of investigative things I would like to do like measuring the gain of at least a few more vehicles and rooms and doing some distortion measurements with push pull drivers versus push push.

Is very, very cool. B)  Reciprocal gains from the room, push-pull experiments, great stuff ... love to read it. Keep us informed/let us know how to help.

 

Something I think would be an asset to the work you're doing here is better quality free air driver excursion videos. Please, no offense intended, however the previous ones could certainly be better.

 

As always, if there's something needed from the community here, I'd think the majority would sure like to help. I can't speak for everyone, but I know I'd help most anyway I could.

 

Thanks for everything.

It would be a bonus to also get the missing UXL-18 THD measurements.

 

LMS-R2????

 

Whoa!  I did not know about that one.  Is it is step up or down from the current 5400?

Its an in between, larger motor than the R and more excursion More sensitivity , but still.a 3" coil

Very interesting!  

Is there an ETA for this new monster?

No eta, it has a new surround which is currently a 15" BUT 18 is planned

Thanks for the support, i need to get my butt in gear, been working on some pro projects which have consumed much of my time, ill plan to put work into The prototype this year for sure :)

I appreciate the enthusiasm!

Cool. Seriously one of my all time favorite 18's are my Sound Splinter RLp18's which TC manufactured. I always wanted a version that was always around but also maybe with your LMT coil. Basically an 18" version of the LMS-R. Something for someone who wants the LMS-Ultra but doesn't need shoebox sized boxes and/or 4kw input power capability. Bbbbuuuutttt I'm sure there is a reason these things don't exist. Probably make it harder to sell the Ultra. Mmm... maybe. :D

I'm sure WiSounds would put one of those (or eight) to work...he always loved the 5100 driver.

Really? Damn. I haven't heard from Justiin in ages. Didn't even know he had one of those drivers. But... what you say is true! :D

We can update that Ultimax15 right on up to the upcoming Ultimax18 now. :D

Yeah...Agreed. Nothing against 15's but if there is a whole family of drivers I'm typically going for the biggest one.

 

 

Kyle,

 

That grille looks expensive buddy...Also you won't mind If I stuff a couple of the ports and see what happens to the tuning on that?

Is it possible to get some reviews of "Flat Pack" subwoofers?

I don't have any skill with tools and these flat packs seem like the perfect thing for me to do a sub build. They only need wood glue, some clamps, and a little patients.

I think I can do it.
