Busted subwoofer, anyone built or assembled subs before?

They're budget subs as was PDR-10. You might want to upgrade to two of these ;-)

It was very much a budget sub when I bought it, probably 24 years ago, but for the usage it gets I'll only change or upgrade when it gives up and dies, it probably still gives a lot of subs a run for the money. Although the repair option wasn't something I even knew about, it's certainly something I would have considered.

The Linn AV5140's it works with also reduce the need to change (active with Tag 5x100's).

£1400 isn't bad, compared to some brands. Tonewinner is new name in subs, so unsure of long term reliability and availability of replacement plate amps

Checkout Perlisten, JTR and Ascendo. I wouldn't spend that sort of money on a sub, of of those big subs is equal in price to all my subs and my front LCR array.

Bit of an update if anyone cares...

It sounds sooo good now.. So much more tight /punchy/ controlled whilst still delivering the under 50hz esoteric sub bass.

Playing a 20hz sine wave is audible..

Well audible is probably the wrong word to use but you can feel the pressure in the air..

but it still kicks hard at higher bass frequencies when listening to music as the music demands.

I suppose that's kind of obvious as the performance would have been steadily degrading as the foam surround slowly lost it's integrity over the years until it finally split and allowed air to move freely from inside the box to outside the box.

11/10 repair... For 15 quid, you've got nothing to lose unless you fancy spending £300+ on a new active sub, or even say £100 on a replacement driver.

I'm absolutely stoked with the repair!

My neighbours, probably not so much.

Nice job, nice to see people saving their cherished equipment with a bit of time and research on fixing the problem. Less E-waste and saving something you enjoyed to enjoy for longer. From the original images it clearly showed it was finally age that got it and sadly that is the case for a lot of equipment even well cared for will finally show aging and need some restoring.

Good post this will encourage more people to do the same and make them realise they can save their equipment in a cheap and satisfying manner, I'm sure the experience has made you appreciate the speaker design and how it all works.

This sort of ethos was one of the main reasons I went with a BK Electronics sub, after reading many people say that they will readily replace parts and at a reasonable price. I really hate this throwaway industry we seem to have moved towards. Repair rather than replace where possible gets my vote.

Yep already watched a few vids of people doing it.. I picked up one tip to get the surround centered with the voice coil without cutting the dust cap off and fitting shims...

Once the surround is glued to the cone and set...

... if you wire a standard 'square' 9v battery up to the speaker, the cone will go to full extension, allowing you to put the glue on the chassis, under the foam, then disconnect the battery so the cone and surround drops down perfectly straight onto the glue.

Ive got the same sub and have to do the exact same repair, I guess they are all failing at the same age.

Any tips please and any vids you watches to help?
Maybe a mini step by step guide so thst i dont mess it all up?! Thanks.

The main thing is take it slow and don't rush it.. Do it over a day or two if possible, so you can walk away from the job and come back to it.

Removing the bumper neatly and the knackered foam and getting it all cleaned up is pretty critical... The bumper /gasket in my case is actually made out of layers of paper /card so it's quite tricky to take that off without ripping it to shreds...

A craft knife /razor blade and some really small screw drivers is good for this part...its glued on so theres going to be some collateral damage, you just need to minimise that damage.

I managed to mangle mine up a little bit, so go really steady on that bit!
once it was fully removed I pumped some general purpose hobby glue into it and pegged it up, set it aside and let it set.

in terms of videos, theres a bunch on youtube, watch a few and that will give you the general jist of it, and how different people approach it.

this one is pretty good, but hes a bit rough and ready, I'd probably go a bit more gentle!

Oh, and use use T-7000 or T-8000 glue for gluing the cone to the foam surround, and again for gluing the foam surround to the speaker chassis.

I only used the general purpose craft glue to fix up my gasket.

The really critical thing is the cone needs to move up and down totally straight.

Once you've stripped the old foam off.. If you press the cone down on one side with one finger gently, you will be able to hear and feel it scratching on the voice coil inside under the dust cap ... that means it's wonky.

You need to avoid that... If it's moving up and down totally straight there should be no scratching noise or feeling once it's glued up, it's quite a small tollerance but youll be able to feel it in your finger via the paper cone.
