    I have a set of 901 series 2, that I bought as new back in the 70s. How do I know if mine need to be refoamed?
    They still sound great, and I don’t hear a diminished quality of sound. Could mine be in good shape, or was mine not using foam? I. Have never taken the grill cloth off to see the speakers. I’m a bit hesitant to take the grill cover off. I think I see one staple on each side, not three staples on each side. Somewhere I thought I read/heard that series 2 did not use the foam that is prone to deteriorate. Any thoughts you can provide for me are appreciated. I feel like they are not broke so I don’t need to fix them, etc.

    Thanks so much for this. I got the old 901s my father had while studying at university and now I'm able to revive them 🙂

    For attaching the rear grill, you suggested the adhesive for the foam surround. Is there other good alternatives? Hot glue or double-sided foam tape?

    Great video. I recently found a set of these in an attic of my old house. I need to repair them. Also does anyone know of a receiver I could purchase that would work well with these? thanks!

    I watched your video because I was thinking of buying some 901's, which I subsequently didn't. Regardless, this is the best and clearest DIY video I have ever viewed and I must compliment you on the entire production. Very professionally made!!

    I bought four 901's pretty cheap, and of course the foam was gone. I had been told by a repair shop that this was too hard to do and I would have to drive my speakers 5 hours one way to get repaired for $230! After watching this video, I decided I could do this (Don't challenge me!). The repair kit arrived and once I got in the swing of things, it was really easy. It took about 8 minutes per speaker once I had all the old stuff cleaned off. EASY! Just ordered another kit to do the second pair!

    Here's some things I would add to what this video teaches:
    – Take your time with the cleanup of old foam. I vacuumed out all the old stuff and dust.
    -You can do the cleanup with the speaker in it's normal upright position. It keeps the old foam pieces and dust from falling into the speaker and makes it easier to keep clean.
    – After scraping most of old foam off, rubbing alcohol on a Q-tip works great, plus some on a rag at the end to get the remainder off. I worked around each speaker by quarters.
    – It was easier for me to hold the new foam in my hand to apply the glue to the foam and hold it while applying glue to the housing.
    – I timed his installation so that I knew how long I had before the glue set, and I gave it about 2-3 minutes for the initial foam to speaker to set before moving to foam to housing. I used a chopstick to help set the foam into the glue (and cleaned the chopstick with the rubbing alcohol when needed.)
    – The foam pretty much centers the speakers, and it was easy to feel it they were off. I only had one out of 18 I had to adjust slightly.
    – There's a chance when working with old speakers like this that your activity will awaken some sleeping spiders LIKE THE GIANT BROWN RECLUSE THAT CRAWLED OUT OF ONE OF THE SPEAKERS! God, I hate spiders.

    I've done four 901 IV cabs, 36 speakers is ENOUGH experience for life for me. One set rotted in an attic. That set was easy and no problems with rubs. The second set were actually "played" with deteriorated surrounds. About 5 or 6 of those couldn't be "saved" (they rubbed) and had to be replaced with other 901 IV speakers. I assume "playing" those speakers with bad surrounds somehow deformed the coil former and voice coil.

    I got a pair of 901 IV's in the early 80's. They haven't been used for almost 15 years now. Having seen this, I'm going to pull the cover off the back and do an inspection. I'm expecting to see dry, cracked foam :-). But, this video gives me confidence they can be brought back in to service.

    I purchased a kit for my old Genesis speakers that I got back in the late 80's.  The surrounds on all the woofers and passive radiators had dry rotted and the speakers sat in my spare bedroom for years unused.  The kit installed easily and the units sound better than ever.  I highly recommend this company if you have vintage speakers that need repairing.  Don't throw them out!  I love being able to use the old school speakers on my modern Onkyo receiver.  Now I need to replace the surrounds on an old pair of Sony speakers sitting in my garage.  I look forward to resurrecting them from unused to used.  Thanks to Simply Speakers.

    Amazing video – I'm about to buy some 901s always wanted them – but was very worried about the drivers – now I have seen this I feel reasured to go ahead & buy them – -only other thing is if there are lose wires or any crossovers in the unit which i guess there are – and if those are broken -how do get to them – is there any videos on that -BUT a stunning video relly helpful – always wanted apair – now if the seals can be repaired -thats ace news – very good video 10 out of 10 🙂
