Pioneer S-1010

Hello:

I have a pair of Pioneer S-1010 speakers and the 10" woofers are missing. Do you guys have any suggestions of what a great sounding replacement 10" woofer would be for these speakers? I also have the 12" passives but they are not in good shape, would it be better to replace them with aftermarket also rather then reform or recone the oem's? I'm not hung up on trying to find the origional cast frame replacement speakers so any suggestions of what I could pop into these cabs to make em sound great would be appreicated. Thanks for your help!

Can you post a picture of the speakers... cabinet and woofers? I have a couple vintage Pioneer cast-frame 10" woofers, that might be usable. They need repair, but I can do that here, if there's interest in them...

You'll definitely want to just re-foam the original passive radiators. No way to really get an exact match, otherwise. Besides, other than the foam rot, PRs rarely cause problems, unless someone's caved them in or something. No voice coil to burn out or buzz...

Gordon.
 
Items Needed!

What I need to find is a new cone for one of the 12" passives and a complete 10" woofer (one is missing). Anyone have any to sell?
 
The Orion calls that a 14" passive?
Look like they use the HPM supertweeter.
Orion's MSRP for those is $1300+ per pair.
 
Oh, I meant to add that the driver looks like those in the HPM series, too. That should give you a few more chances to find a replacement.

Check ebay for HPM-40/500 woofers.
Oak Tree Ent. has an HPM-40 woofer, cosmetically challenged, $95.

Takes a while to load (dial-up), and is about 2/3 down the page.

IIRC, the HPM40 woofer is paper/carbon fiber cone. The S1010 woofer in the picture above, is the same woofer as the HPM1100, with the graphite-polymer cone... different cosmetics, possibly different sound too. Apparently, a different size passive radiator (that's definitely a 12" hole, where the HPM1100 used the 14" passive radiator) is used, but the exact same 10" woofer...

Some Options

Would I be giving up a lot to replace both woofers with the new hpm style (pleated surrounds) and have the shop recone the passives with paper?

I would rather use the woofer out of the 1100. I checked Epay and didnt find anything for HPM 1100's - does anyone know where else to look for one.

Thanks guys for your help on these - at least now I know what I need.

Lemme check, I think I may have one re-foamable good HPM1100 10" woofer somewhere. I know at least one of them here has a broken cone, but the other one may be OK...

Otherwise, I'd want to know what the resonance frequency of the pleated-surround woofer was, compared to the HPM1100/S1010 woofer. If it's pretty much the same, then yes, you could easily just use those.

If it's not the same, then I'd recommend either 1) hunting down a good HPM1100 woofer, even though it may take a while, or 2) having someone like me or anyone else who can, take a PAIR of damaged HPM1100 10" woofers, and put a new paper cone with a foam surround in them. IME, you can take ribbed paper cone kits, and coat the cone with PVA (ie, white glue applied evenly), and you can wind up with an assembly that sounds VIRTUALLY IDENTICAL to the original poly graphite cone. And, if the repairman is careful and patient, you can RECOVER the original voice coil and spider, by carefully chipping away the original cone all the way down to the voice coil... so that ALL that winds up being replaced, is the cone, dustcap and surround. I've done a DIRECT COMPARISON of a paper-reconed HPM900 12" woofer, done this way, with an original HPM900, and NOBODY could hear the difference... I simply made sure I got the mass the same, and everything else worked out handily.

Regardless, reconing the passive radiator with a paper cone should not degrade the sound, as long as you can get the new moving assembly to weigh the same as the original (and it's OK to glue stuff like lead shot to the backside of the dustcap, or whatever, to add weight to a passive). If that is done, and the suspension is about the same stiffness (the spider and surround are roughly identical in compiance to the originals), then the PR should work without a hitch.

Regards,
Gordon.
 
Hey, one question: Anyone know how much different an HPM40 woofer is to that from an HPM200? I've got a single HPM200 woofer around here... I could easily compare its suspension to the HPM1100 woofers that are also here...

Regards,
Gordon.
 
Thanks for the info

I'm not sure what the resonance frequency is on the origional woofer - I cant find any specs for it (I've tried searching the web and calling around) other then the old Pioneer part numbers 25-766A which was replaced by 25-766S and is NLA. How could I find out the specs on these speakers?

Gordon, if that woofer you have is a good match I would take you up on that.

The one passive has a good cone but if I have the other papered then should I do the other one in paper too? or just leave it alone?
 
By general principle, I'd prefer to have both passives have the same cone... but really, it matters FAR less on a passive radiator, since it handles absolutely no midrange (which is where the different cone material makes the most difference in sound).

I'll check on the HPM1100 woofer ASAP... may be able to get to it tomorrow...

Regards,
Gordon.
 
HPM 60 Midrange

Gordon

Here is the photo of the midrange I have in the HPM 60's. Let me know if you have a dust cap for it.
