TDL RTL3 Blown Mid Bass unit
 
Hello,

Just checked my pair of TDL RTL3 loudspeakers and one of the mid bass units is open circuit.

It has written on it 172-NS-06 and has squared off corners.

I beleive it is a Monacor drive unit and someone mentioned it may be a variant of a SPH 175 available.

Can I use one of these instead ?

Or does anyone have a original Mid/Bass for sale?

Any help appreciatted

Nice one,
David.

The current revision 175 will almost certainly have very different specs so the only way you would get consistency is to get a driver out of another pair of RTL3's. I'd keep an eye out on ebay as you get some TDL stuff from time to time.

Hi ,
Lockwood Audio (Ruislip Middx UK) had piles of TDL drive units a few years ago . Maybe worth trying them ?

cheers

Infact, it was the same driver used in the RTL2 IIRC:

Some spare tweeters going there for cheap too. But that's probably how much they're worth anyway ;)

Hello,

Thanks guys for the help. Yeah, I will probably pick up a pair of ebay!! as you say get a cheap pair of RTL2's and it will give me some spares.

The major problem with these speakers is there low impedance presented to underpowered amps (with a lack of current rather than voltage) causes clipping etc.

Vikash, I was wondering what tweeters you would recommend. ?

Have recently upgraded the crossover. Had burn't out resistors and caps and I put in decent film polyprops. Air core inductors etc may be an improvement also. Might do that later.

May have to hand draw (reverse engineer) the Xover schematic. Anyone got it ?

Thanks again.

You could try Speakerbits in Melbourne Australia

From their website-
TDL 5" magnetically shielded bass / midrange. These are genuine TDL spare parts - no data available though. The cones are a very nice coated paper / surround design. Uses would include centre speakers and small shielded monitors.
Stock code : ST115

They are in their Clearance pages $22 Australian
