Cannon TLS 1030 Speakers

So, my recent foray into vintage audio is having ripple effects around our place. My father in law has a set of Cannon TLS 1030's sitting around. The foam surrounds are gone.

Is it worth having these repaired? No idea what's involved with getting speakers fixed - is it expensive?Resized_20190610_115835_1992.jpg Resized_20190610_115835_1992.jpg

Cannon speakers are good but not great. They were made by ESS, with Motorola piezoelectric tweeters that can sound decent. I'm pretty sure these have a passive radiator in the back, which will also need to be refoamed. Make sure the radiators are still there; if there's just a big hole then you'll have to source those as well. I wouldn't put too much money into them; I'd probably go for inexpensive generic surrounds and call it a day. It's probably not worth doing if you're not going to do it yourself.
 
DIY refoaming is fun, rewarding, and not much money involving.
Before refoaming though, make sure all drivers are alive and kicking ...
 
Had a pair decades ago. Flat passive on the back but I can't remember if they had a piece of hardboard on it as a weight (like the ess cousin). Very efficient design, good sized magnet on the original woofers. Worth a refoam. Punchy, west-coast sound.
 
hope someone still knows something about these Cannon TLS1030's.
I am replacing my woofers and the 10" passive radiators on the back.
one question, the new passive radiators are quit a bit lighter in weight than the original ones.
if I glue a layer of cardboard to the back of the disc it's very close to the same weight. should I do this are is it not worth the hassle?
I have read that a change in the mass of a passive radiator changes the tuning of the system, heavier radiator gives a stronger low end response..
any thought????
 
My Dad bought a pair of the 1232's. Of which I now have. Taller version of the 1030's. SimplySpeakers has (or had) the foam kits and the passive radiators to replace the bad ones you have. Fairly simple procedure replacing them. I believe these came out around 1978-1980.

You should match the mass of the old PRs with the new ones, except if you're replacing the woofers, the tuning will no longer match, and all bets are off. What was wrong with the original woofers?
 
Swechsler, The woofer in one of the cabinets was shot and repairing cost higher than replacing with a more potent woofer, heavier magnet, higher SPL rating and higher watt rating.
so I bought two of the woofers so both cabinets will be the same. Do I need to use the software to try tune the cabinets then?? I tested the speaker with the drivers in the cabient and no passive radiator on the back, open hole on the back and no fiber fill in the cabinet either, so bass wasn't as full as it can be but it was still exceptional sounding. It seems like with the box sealed and the P.R. on the back it should be a great sounding speaker, not the same as it was but maybe better???
 
A cabinet with a passive radiator is essentially a ported cabinet, so yes, it needs to be tuned, and in general, dropping a new woofer into a prebuilt system is rarely a recipe for success (this point has been made many, many times here over the years). You may find that the woofer you chose is not ideal for the cabinet volume no matter what tuning you give to the PR. Or you may be happy with the sound, but that doesn't necessarily mean that it will be accurate or flat.
 
Thanks for information, It probally doesn't matter to me these days anyway, at 70 my hearing is just a fraction of what was back when I bought those speakers back 1977. Hearing aids have gotten back a little bit of high end rsponse but nothing like it used to be... I won't know how close to flat response they will sound unless someone else litsten to them for me..lol
 
I've seen that video on tuning a cone type passive radiator but mine is a flat one. Just a flat foam disc with cardboard on the back. there are no Ts parameters for the flat radiator on the manufactures web site either. so not much help. Also the end section of the video he tells you how to find the tuning frequency of the passive radiator with the rice, but he doesn't say how do you tune it by knowing what the tuning frquency is??
 
Swechsler, not sure if if it's possible for someone to be able to figure it out, but this is the woofer I put inmy cabinet that is 23.5" H x 13"W x 12.5" D i came up with a volume of the cabinet is 62.6 liters, attached the spec sheet on the woofer,
also the passive radiator has no specs to use WinISD here is a pic of it. the weight of the passive radiator is 33 grams not the 54 grams the web site claims it to be. Can you tell with what I've shared if it will work and or how good or bad it will be?

I've already written most of what I know, I'm not a speaker design expert (I just know enough to be dangerous) so I can't tell you how well what you've got will work. You can weigh the PR down for tuning with steel washers glued to the back (I'd probably do it in sets of 3 to keep the distribution even over the surface). If you have the patience you can tune it by ear (do one speaker, add a little weight at a time, listen, compare with unmodified, repeat). You're probably not going to get super low bass with a Fs of 48hz though.
