Spent last weekend to pick up four pieces of TMS-4


http://200sx.kicks-ass.net/djhypnoz/img504e2fa7550a9.jpg

Have tried to read as much as I could on this forum about these TMS boxes to not make a fool of myself when buying them.

But when the ad came out last week knew that I would not have any time to reflection if I would like to buy these four boxes. I have followed the secondhand market in Sweden all summer and TMS-4 is not out long before ads disappear (if the come out on market at all). So unfortunately the deal went much faster than would be optimal for finding out what was in the boxes.


I took some pictures when I looked what was in the boxes before the purchase.

All Mid Drivers I think looks like original Ls1001 and even whole without any damage?

Even all the 18" looks like original Ls1801?, but two were unlabeled and has smaller midholes in the magnet than the two with original label, someone who knows exactly what kind of element this is, early Ls1801 perhaps?

Two boxes have Hf BBC drivers and are also the original i guess, its Early B&C Drivers (Name of company was BBC Speakers untill 1988)

Hf Beyma CP-300 drivers are also the original what I have read on this forum?
To bad one of this was blown and its seems very difficult to get hold of new Diaphragm.
(only one blown driver of total twelve is kinda ok anyhow i guess)

Please comment on anything you can contribute.

Ps. Wish it would be Tony Andrews "Tony A" signature on the picture, but is more likely "Ray" i guess?

All you boxes should have the beyma HFs in, should be CD-102 badged but it was a beyma with the LS-1001 and LS-1801.
 
The x-overs are PX 4.0, but TBH rip them out and and put a pair of NL8s on each boxes and run them 3 way active.
 
Looks like a nice set of TMS-4s, also I wouldn't use the NL4s in that current config, shared 0v lines on cabs are the stuff of shredded amps, if you wanna run 2way over NL4 then wire each XLR seperately to the NL4!!!
 
Unlikey John or Tony made these, AFAIA they were never that "hands-on" onece the boxes were in production.
 
I am guessing you have the old TurboSound North road, London badges on them as apposed to the later Star Road, Partridge green one...
 
Real peice of history....
 
Some of mine having fun this Summer..

Im probably wrong but when i look at turbos "COMPONENT MAP" it seams that my early Serial numbers dont even is in this file..

S/N 101454  ..  so my guess is that CD-101 (Beyma CP-300) is original in this box Like the rest of early serials:

010726 -012166             LS-1801

LS-1001

CD-101

PX-4/111*

right or wrong?
-------------------------------------

I will do as you recommend and run 3-way active in the near future, but would have liked to test them as they are now with my own amplifier (I heard them on the purchase of the sellers amp´s). Partly because it is a cost for DSP and additional amplifiers, but also to get my own idea of ​​before (passive) & after (active) :)
-------------------------------------
I will skip the  NL4s, thanks for this Council

---------------------------------------
someone else who has idea about them unlabeled 18" ?

----------------------------------------
shagnasty: Your setup looks good, better then 4 "TMS-4" per side :) easy to stack!

I'd cut the wires to the NL4s before even using the XLRS or just wire all 4 not just the 3!! Smile

I still have a CP300 diaphragm in stock if you need one.
Or if that suits you better, a CP-350 diaphragm is the same and can be made to work in CP30 and CP300. Just need to cut off the slide connectors and a few mm of plastic to make it work.

Peter Jan You made my day :)
 
Have you modified CP-350 diaphragm in cp-300 yourself and made it work? If so, have you compared the sound after with an original Cp-300? 
Is there no changes on 300 vs 350  diaphragm more then connectors (and some plastic)? 

whats your price for the original Cp-300 
diaphragm?

I have replaced many like that when Beyma was temporarely out of stock with CP30/300 diaphragms when those drivers were still in production. Most in original Beyma drivers, but also a lot in TMS-3's (before EV DH-3 was mounted). And later on it was out of necessity when production of the CP-30 and CP-300 drivers stopped and diaphragms became unavailable some years after. The voicecoils, the aluminum membrane, everything is the same between the 3 types, exept for the connection by means of solderlips for 30/300 and slide connectors for the 350 and the extra plastic overhangs where the connectors sit on. The cutting, grinding or however you do it, is needed to clear the hood of the CP-30. Yes, only the CP-30, not for the CP-300. Long time ago I had to do one and I wasn't sure anymore about the need for cutting/grinding material to make it fit, so I took a CP-300 (still have some on the shelf) and checked it. DCP-350 fits perfect without issues whatsoever. So does a DCP-350Ti by the way, but the different diaphragm material (Titanium) makes for a somewhat different sound. Maybe not an option in this case or at this time, but just keep in mind that it's an option that may be useful in the future.
Anyway, to answer your question, there is indeed no difference whatsoever between diaphragms of CP30/300 and CP-350, other than the connection and the extra plastic material. There was a change from glassfiber/paper coil former to kapton coil former, but that was a running production change for many models, not just a one model change to another. Driver structures are somewhat different, phase plug/slots aren't the same, but diaphragms are identical.

Well, to be honest... if Beyma is easily available in Sweden, I would just get some brandnew DCP-350. What would be the price ? 30-35 Euro something like that. If I asked 10 euro for an old DCP-30/300 plus the amount to send it over, you might end up almost the same price as new. But if you are okay with that, sure I will drop one at the Postal office for you Wink

Not 100% sure, but from the look of it, I would say Fane.
