Hi, yes the super compact, he could have replace the tweeter, the mids is foam surround, all the mk I , usualy have the mids EMI like your Tls 50 (Als 40, tls 50 et super compact) or sometime Peerless mids was used, not too many, even the woofer can be peerless, not kef sometime.Anyway the Audax is fine, same as Peerless.

These were a Kit speaker system utilising the Bailey design transmission line concept, utilising the "Concerto" driveline.
These were advertised as "Try a Triangle" as all the internals were triangular shaped and thus were designed to cut out resonant frequencies due to non symmetrical internals that cancelled out reflections.
My very first TL's were a set of these which I replaced 10 years later with a set of TLS-80 Mk II's and then added a pair of RSPM Mk 5's (first Improved's) to the mix. I still have both sets in current usage.
Ok these sound amazing..but they have no info..it just says in a metal sticker , STUDIO and serial # which both are identical.
Does anyone have any info on these?
Sound is amazing on one..the other has a static sometimes. Havent checked speakers or tweets with my odometer.
Im just happy i have another brit in the family...i have some rogers studio 1 some jr 150s and now these...cant wait to see whats the static is about..hoping its a cap.

Congrats!!
Do you have a photo of the metal decals on the back? Someone here might be able to decipher the specific model from that.
regarding the intermittent static- do you have a tone knob on the back to adjust the tweeters? If so, it might benefit from a deoxit cleaning to remove dust and corrosion, similar to what we have to do with volume knobs on receivers. Otherwise if you notice the static happening on dynamic sections of music etc it might be a loose wire inside the cabinet.
The falcon acoustics crossover kit will help you replace the worn-out caps if you suspect that’s the issue, and you can inspect many of the wires at that time.

Also whats that around my main driver..its like silocone
Looks like the center dust cap , or the center of the cone came free from the voice coil. This may be the static your hearing. Id see if you could get a better look at the drivers. Maybe have some one go over them that specializes in speaker repair if you're not up for the job.

Actually imf made them like that..i have a very rare imf studio. Epray has a single one for sale ..look up imf international, the studio model..you will see that this one also has the silicone..very rare indeed

yeah so on the silocone, Falcon said they should not be hollow..which they are..so they need to be replaced..Thank god I think I bought a some dalesfords a few years ago i have in a box.
on the tubes, alot of people have tried to upgrade the tubes with other material. THis will ruin the IMF sound..read the link on how they chose every part of this speaker for its tonal quality.

Hi, I have seen many studio or TLS 50, the early model could have different woofer brand,usually peerless or kef, your's is a Tls 50 call studio, why I don't know, the midranges tube have a roll of foam, nothing fancy like it said in the description, it is only advertising to make it more special. If you remove your woofer it's gonna be SP1014 kef.I like to have a look at your x-over. I have a pair of prof mk 3, modify the midranges tube inside with adding active carbon half inches thick, because it's known that at high volume the sound get mix with the woofer T-line and it need to be more insulate and not true you will ruin the IMF sound and the contrary. That is my experience,Yvan.
from Falcon's website, it looks like the Dalesford could be a close match to the Kef sp 1014's, is the Feroba the same size?
what did you mean about them being "hollow," is the cone separated from the voice coil?
where are you located? hifishark shows a few sp1014's currently for sale, only one in the US thought (much more common in Europe of course)

Its very odd silicone..probably was there for a long time..it has become jello like and i can probably exacto knife it out. Im in Virginia. I think im just going to go with dalesford it turns out i only have one woofer so need another one..just posted WTB in barter town
Hello everyone, I have picked up a nice pair of tls 50 mk1 and my tweeters don’t work, all other drivers do. Has anyone replaced the original peerless tweeters with the new audax tweeters than falcon acoustics sell? They are a direct replacement according to the website but I’m keen to here peoples opinion on them first before I buy them. Thanks Mike
