Paradigm Titan Bookshelf Speaker Rebuild

Repairing a set of Paradigm Titan high performance speakers.

[@johncopley974]

I’ve done several refoaming jobs on JBL, Pioneer, ADS etc. Always used the 9 volt battery method. Great video as always.

[@allenyoung9092]

Wow! They really have a nice sound never experienced a repair like this will have to try doing this love your videos outstanding...

[@sonyajones]

Nice work! I've ordered some repair kits for several speakers that need re-foaming. I had just kept pushing them to the back. Have some Pioneer and a couple of 60 year old 12" Magnavox speakers that need re-foaming. Love the videos, Dave. Thank you.

[@tedclement5320]

Do tell where you got foams for 5 bucks. I have a V3 set that need some love.

[@brunolagace1135]

I did a few of those. The most expensive one was a JBL I replace the spider the cone and the foam. I did a few Altecs and one Paradigm Sub. You need to take your time and clean everything well went your are not use to it. Those little Atoms do sound great I think they have a Vifa tweeter in them. The woofer was made by Paradigm. The older Paradigm were the best I still have a pair of Paradigm model 9SE MK3 that I use every day and a pair of Atom in my surround system.

[@Michael-li3id]

i just inherited these exact same speakers, and need to refoam them. thank you sir.

[@12voltvids]

Lee's electronics has them.

[@stevegottwald386]

Hi it's very nice to see how you fixin this speaker! Great work

[@larryhuff3383]

I guess the positioning of the spider is more critical for proper gapping. If the spider doesn’t need replacing then this method of cantering works well. Otherwise shims are needed to properly space the voicecoil. This is a great tip by the way..

[@12voltvids]

Shims only needed if spider is removed such as for a voice coil rewind. If the voice coil is shot i would be trashing the driver myself.

[@larryh8072]

I would agree if the drivers are not that expensive. It may be cost effective to recone some high end drivers though. Some guitar amp speakers can cost quite a bit for the drivers.

[@b.powell3480]

Hi Dave ! Great video ! Great set of speakers ! Now, you can drown out the sound of your neighbors lawnmower when he's out mowing ! Lol 😆 !

[@djijspeakerguy4628]

By the way, the glue that was originally holding the driver down on these was only there from when the front baffle was attached to the sides of the box. In those days, they seemed to have assembled the box after installing the drivers. The v2 through v4 were assembled differently and did not have that glue around the border, only on the corners of the box.

[@christopherrichardson8026]

Where did you find them for 5 bucks? Thanks for the video.

[@bobsoft]

I had my KEF speakers rebuilt at Speaker City. Next time I will do it myself.

[@12voltvids]

They charge an arm and a a leg

[@ubernerrd]

Nice work. What app are you using for the spectrum analyzer? I tried looking on the play store but there's a bunch of different apps which don't seem to match.

[@12voltvids]

Sound analyzer.

[@carlosoliveira-rc2xt]

Are you sure it was vibration affecting the clock screen?

[@12voltvids]

Yup

[@tyronenelson9124]

I have a pair of weird old b&w bookshelf speakers, these ones have a red led on the front that comes on as the speakers cut out if you over drive them.

[@carlosoliveira-rc2xt]

They'll sound better if you take that out of the circuit.

[@garryself]

Now I know the Lee's surrounds definitely fit I got to go get some! I take it you got the JBL 6-3/8" OD ones?

[@12voltvids]

Look them up on web site. They list the sizes.

[@garryself]

@@12voltvids they do. That was the closest match I could find and was the one I wrote down.

[@greengrayradio1394]

Good refoaming! I suspect your class D amps has so much RF on the outputs that it interfers with tne clock monitor

[@12voltvids]

Shouldn't be rf on the output. That's the job of the lpf to cancel out the switching signal.

[@greengrayradio1394]

@@12voltvids Yes, it is. However, I have seen/heard "class D" amps with insufficient filtering causing massive EMI from the switching

[@charliea1963]

I bought a repair kit with shims, is this a waist of time dave? I went with rubber instead of foam.

[@12voltvids]

Shims unnecessary unless the spider needs to be reglued.

[@12voltvids]

My Polk's use rubber suspension. These blow the Polk's away.

What little amp are you using?

[@lezchislett51]

How on earth is the back removed screws out it wont budge.

[@12voltvids]

Its tight. I had a hell of a time getting in.

[@len9518]

Foam centers itself. Remainder of black material on frame should have been removed first, and replaced afterwards, but result was acceptable.

[@12voltvids]

Black material on frame was not removed as that would lower the foam mounting point and the original was glued to the cardboard. The idea is to not change the angle and have the foam pulling the cone down.

[@carlosoliveira-rc2xt]

The speaker was $200 CDN retail. Keep things in perspective.

[@jeremytravis360]

I still have an old Lowther PM6 which I'm told I can still send them

[@EldaLuna]

nice was wondering if ever get to these that was pretty fast.

[@edstud1]

He never discloses where he got the repair foam?

[@12voltvids]

I went to the local electronics parts store. Lee's electronics in Vancouver. They stock all the popular sizes and they are cheap.

[@ИванИванов-л1ф8э]

don't repeat, this is the worst job one can do. 1, poured a lot of glue. which increases the weight of the diffuser. which affects the characteristics of the speaker. 2. did not center the diffuser, for this it was necessary to peel off the protective cap in the center and insert a thin material into the gap, otherwise it will be skewed and the wire winding on the diffuser will rub against the core of the magnet. 3 did not clean the basket from the old suspension.

[@12voltvids]

Running the speaker on 50hz oscillator centers the cone. The glue used was special speaker cement which does not add to the weight. The speaker sound fantastic. I use them every day on my bedroom system. Have done many speakers this way. The only time you need to shim the voice coil is if you open the spider. That is what centers the voice coil. Pumping the speaker at 50 hz will center the cone on the surround as the glue sets up.

[@zhrob1]

@@12voltvids Is there any other way someone like myself could centre it without having the 50 Hz tools...? I was hoping to fix my an old 3 way Sanyo speaker.

[@12voltvids]

@@zhrob1 you can get an app for your phone to generate the 50hz tone. That is if your phone has a headphone jack to connect to an amplifier.

[@zhrob1]

@@12voltvids thank you sir. And btw I like your taste in the 80s style watch!

[@jeffclark5206]

So many downvotes already. I can only assume its because you didn't center the foam, that triggered my OCD lol.

[@12voltvids]

The foam is centered. That is the reason for the 50hz tone. It centers up the foam with the cone before the cement sets. You can be off a fair bit and once the speaker is fired up the vibrating will center everything. At least that is what the speaker tech from PSB, at the seminar i attended 30 years ago was telling us. That's why you fire them up before the glue sets too much.

[@12voltvids]

John shithead has already demanded KZbin take this one down at least twice. Next my public email will be spammed with religious crap again.

[@jeffclark5206]

@@12voltvids I was referring to the outer foam that attaches to the frame not the cone portion. In the video there is a good gap on one side but no gap on the other. In my mind it would make the foam slightly distorted.
