Ok, I've been looking for the real old drivers for the worlds oldest tms-2s, to make them original.
So now I got these two 15" with no turbobadge, did anyone see anything like this before?



They're from serial number 250, they also have cd-101 that looks like new, they've been stored inside for all those years! I plan to put these inside serial 2 & 4 together with some real old turbo fane 10" with quite small magnets. So, after 5 years I think finally become original like they once were.

Ok, I've reached the conclusion that they must be original as the old 10" drivers has the same funny small backplate. I started a separate thread on the subject not to hijack this one:-) -Look here:

Can anyone help with info on some tms3 cabs I have?

They have ls-1504 bass, 1001 mids (all 15s and 10s have the silver/blue labels) and a jbl 2445 top end BUT have "fitted with the v-2" on the input plate suggesting the 2445 is not original?

They also have a 500uf cap across the mids and two small blue poly caps on the hf with a small resistor. Is this just a protective device in case lf gets mixed up into mf/hf channels?

Was there a passive mf/hf version and does anyone have the xover schematic?

Lots of questions I know! :D

Whow, those are old fane drivers aren't they?

Crossover schematics used to be on the turboserver until it got all behringer.
Unfortunately I was not smart enough to download all:-(
In a week I'll pickup 6 pcs tms-3, then I can look in them.

One thing sure is strange: To my knowledge the V-2 was fitted in the later tms-3s where the earlier model had that awfull jbl weapon inside. But your model sounds like an earlier version with those drivers (later ones had PD ls-1507 & ls-1004) I have 4 pcs brand new ls-1507 and used 1004...

Perhaps they downgraded it to the old version to be similar to the others?
Also I believe that quite a few deaf american would prefer to have their ears ripped from the distortion of a jbl 2445 just because of the "jbl" mark and "made in usa" (which is probably mexico:-) Get rid of these ASAP.

You can buy 1" drivers joiners similar to the turbo, also you can get the beyma cp-350 driver used around (the "ti" model is a later version)
But I think you'll be better of with bms. Some use 4550, I prefer 4538, looking at the specs the 4550 appears to have more power, until you look at sensivity, then it becomes obvious that they should play equal as the extra power is lost in less sensivity.

I don't know how well the "V-2" works or how much it affects the sound, also I have no idea how well the high-horn is designed or how well the thing performs above 10khz, some measurements sure would be nice :-)

Yeah I emailed "turbosound" and just got the "contact your local service agent" weak customer service bullsh1t.

Yes it is an old version, apparently owned by one guy from the early 80s, then bought by someone who I have found has a 12 minute video procrastinating about how he will restore them (on youtube) and waffling on about the old days of real audio. He then has a second video when he inexplicably spends DAYS trying to hand sand one back after stripping it of all hardware and going on about having all the drivers "realigned" or some garbage. That exact stripped down cabinet (and the other original) are what I bought. Apparently after talking sh1t for hours he gave up.

The 2445s look rather old so I'd say they have been there a while (probably 20 years). I do have some semi decent RCF 1" kicking around (N450 I think?) But not sure they'll have the balls to keep up...Probably even do ok with some Paudio Bm750s.

An original xover design would be amazing if I can find it, even just for the lowpass section(if they were actually low passed) I can make up a new one for the high end from there with an RTA and maybe the Dayton software.

google for turbosound tms-3 and look at the spec sheet.

They have no crossovers at all
They're 3-way active boxes.

I'll check if there's any protection circuits in mine...

Yeah I thought they were active but have read somewhere about passive versions? Only on the mids/hf obviously.

If they don't exist I'll just go active either way. Actually going to turn the top end into 211s(which definitely had a passive xover) and have 215s seperately as 134kg is just too much.

OH NO, What an abuse of a pointsource system to place it on a line! 4DPA got it right :-)
You have comb filter chaos all over the place, that's for sure, but furthermore the subarray is sooo long it get's caridod unless sides are delayed.
This sounds awful, what an abuse of good speakers (THL is quite new turbo in my eyes:-)
