IMF tls 80 problem

[09mike69]

Well had a chance to try them but unfortunately still the same, very low output from both tweeters.
Low output meaning inaudible.
Sent pictures of the crossover to falcon acoustics and it has been mucked about with.
Also the b110's are not, they're a seas look a like !.
These speakers are the early version of the imf tls 80 that were called transmission line speakers.
Falcon don't have a schematic for this x,over either.
Any help, suggestions.
Thanks again
Mike.

Buy a DSP unit and run them active? You'll need multiple channels of amplification but you could use cheap chip amps for mids and tops.

Build an entirely new passive crossover based on that for the TLS80? It will probably work fine.

Have you looked at the TLS 80 crossover schematic: https://www.google.co.uk/search?q=im...client=gws-wiz

It should provide an idea of where things may have gone astray.

I wouldn't know to use dsp.
the x,over board layout is different to the tls 80 so I can't use one to copy.
Falcon sell a x,over that will work in these I'm waiting for a reply from Jerry on price.
Also I'm starting to think that this problem could've been caused by the mod done by South Coast speakers. It seems odd that both speakers have the same problem.
If you look at the crossovers they have two parallel wires on the board, should there have been caps here ?
Mike.

I have only just come across this thread. Did you get the crossover sorted and the speakers working properly?

I bought new cross overs from Jerry at falcon acoustics. They sound very good.
