JPW P1 - worth fixing?

[jonny_c]

I was given a set of speakers some years back - and really like the sound out of them - moved house the other day - dusted then down and I see both cones are split where they join the foam..

Googled them - and it would seem they are a respected old speaker - seems to be £150 to replace the drivers.

Are they worth it?

Or do I spend £150 on a newer secondhand equivalent? If so what would the newer equivalent be???

Thanks in advance for any advice!!

I once repaired a split cone on a Cerwin Vega using Rizlas and [slightly] watered down wood glue. Gradually built up a few layers of papers in the area of the split.

The speaker was one of a pair we used for discos, parties etc and it was driven hard.

The repair lasted supremely well, for as long as we kept those units.

Might be worth a try before you decide whether to replace both drivers.

Interesting - it’s quite a long split - 12 - 2.30 ish around the cone edge - no real loss in trying I suppose!

If you're not bothered about originality, you can buy generic replacement foam rings for £very little.

Superb speakers and well worth fixing - you wont buy better for £150.

Replacement surrounds are easy to come by and are not difficult to fit if you have a steady hand and a couple of free evenings. Personally I always cut the dust cap off and shim the voice coil as well, as it as it makes for a more reliable and consistent result.

Plenty of places will sell you the necessary surrounds, dust caps, shims and glue (I usually use Good Hi-Fi in the Netherlands, personally) and there are plenty of videos online to show you how to do it.

Looks like a bit of a job! - this one is a clean rip along the foam - the other one is the same but has a tear in the cone as well

A classic problem by the looks of the YouTube video’s

I might just go all out and replace with new

Fair enough, but if you do replace them, please don't throw them out. Offer them up on eBay/Gumtree/wherever - someone will grab them and save them, and you'll get a few quid back

[jonny_c]

Interesting that old split drivers would be worth some money - suppose there would be an originality value to them.


Now I've started looking at Gumtree turntables...


All I have is an old K1 signature Marantz amp and a fairly recent Arcam DAC which I use to play full fat Spotify - which I think sounds fine given how useable Spotify is

But I also want to be able to play my old and small but specific record collection - seen a Project Essential II with pre amp - looks new - £120.. mmm

The split drivers aren't worth any money but they can be repaired! I've restored many pairs of speakers like this - some in far worse condition.

There are plenty of online videos which explain the replacement process. Good luck.

Just got a service bill for my bike of £750!! So might have a go at repairing after all - i’ll Google the shiming thing - bound to learn something from the process - will report back in due course

Boultons are very good, and reasonably priced too. Will be able to sort for £50ish by the looks of things, might be worth a call. http://www.audioloudspeakers.co.uk/boultons.shtml

New units can still be sourced in a couple of places.

I’ve ordered new foam surrounds - £20 inc glue and shipping - lots of detailed instructions around - centring everything seems to be the key.

Lots of chat about capping the tweeter or something in audio land - which might be a step too far as I assume i’ll have to do some soldering - will see what it all looks like when I open them up - also putting steel plate inside the box..

They were designed to a High efficiency Speaker for Valve amps or low output A class amps. A dealer in Harrogate used to match them with Sugden A25 amps or the Audio Innovations S300. Basically a poor mans Snell K.

Definitely a post for the "audiophile bullst" thread

No they're not - from personal experience I recommend you avoid them like the plague.

I wouldn't have put the Vega units in the audiophile category, but the repair was long lasting and didn't seem to result in any degradation in sound quality - not for the use we put them to, anyway

OK, fair enough...…..you had a bad experience; the work they did for me was good. It was specialised production work involving a couple of hundred subwoofer drivers...…..not a domestic job.

Not sure if this is going to work!

'Borrowed' a set of old 90's floor standing ruark templar's while I fix them

Not convinced they sound as nice as the JPW's...
