Danke James. English is so difficult.

Okay, I'm not sure they're a worry to everyone who repairs them.
Surrounds last about 15-20 years. They rot. It happens.
Your separated speaker isn't typical, perhaps someone jammed them without the protective surround, and that ruined the voice coil. Who knows?
Now, you order some speakers that may fit, but do you know if their Thiel/Small parameters are a good match? If not, and it can be a crap shoot, you'll end up with speakers in the wrong type of box, with the wrong specs.
Do whatever you wish, but if you want the best performance from a vastly underrated pair (arguably the best Bose ever made) then you should have kept the original woofers and had them repaired. I don't think that's a hard speaker to find, as I think they also used it in other applications.
gern geschehen, Chris. Your english is better than you give yourself credit for.
My german, ugh, it's horrible.

Yes indeed in theory that is completely true. I dont deny, originals give original performance.
But with some ghaul, I might be on to something fresh. I'm willing to gamble. If they end up sounding better, I'll be so happy.
As for their specs, they had similar curve actions to previous posts made here. But on the bonus side, these new ones have tougher cones which should move more air through the cabinet respectively, without distortion from bounceback.
Well, best of luck with that.

Someone with more experience might be able to confirm this, but apparently the same size woofer was used in the 301 as the 601. There are indications they may actually be the same woofer. Both of which turn up frequently.
As for proper match, I agree it's a crap shoot to get something correct with a "replacement" driver. But there are many posts with claims, including some of my own, that cited improvements. The closer the driver matches the dimensions (volume) and "style" (ported, sealed, etc.) of cabinet, and of course frequency range according to the design of the network, then you'll hopefully have equal performance, or if lucky better. But hitting all three marks isn't easy.

Too bad they went in the trash, I would have liked to try to rebuild them. Oh well.
Interesting, I'm originally from Toronto. All my family (other than my three brothers) still live in Canada.
The Bose 601 woofers had PLENTY of bass. And, they have no crossover point in the crossover, correct Copa? Didn't Bose just let the woofers roll off?

You got me. I've yet to lay my hands on a pair. Might be a schematic in the AK archives. I'll have to take a look.
Sorry, I thought you had helped me with my goofy crossover issues on my pair of 601's. I replaced all the resistors, as that wire inside is brittle, and they had broken free.
I didn't recap, tho. Mexican poly caps inside, figured, why bother?
Maybe I should go back and recap, and add those fuses. Stuff like that drives me nuts, tho they sound really good as-is.

Sweet. That manual helps alot, I have the 3 input post model.
Seems the crossover was tinkered with quite a bit between series II early and series II later in the run.
I don't guess I'll tinker with my pair. Mated to my Carver 900 receiver, the sound is simply stunning.
Quickly becoming my favorite setup.

From picking them up, for me potentially, to liking them so much is awesome. I hope to find a pair some day. Came close on the auction site, but the drive, 6hrs one way, was more than I could justify, time and cost in fuel.
I've saved it in my Bose folder for future reference. Seems the II is the best of the bunch overall.
It's all your fault, man!
At least I tell my wife that. All jokes aside, I was hurting for money when I saw these. Got out, looked them over, and decided no. Sit at work for 4 hours, just itching to go back. I left with cash from the petty cash till and snagged 'em. Replaced said cash, and was glad I did.
I'll never BoseBash wholesale ever again. They actually CAN make some great stuff.

My figuring is to rebuild these the same way I rebuild guitar and studio equipment.
The cotton batting technique was needed because of the distortion that bounceback gives the cones. Stronger cones means less bounceback effect. MESA BOOGIE hasnt used baffling for twenty years because they have upgraded cones which handle high volumes without distortion.
As for replacements, no company I've asked will guarantee against rot, in fact they all claim its enevitable with foam surrounds. So why replace or rebuild something in a way thats just going to do the same thing in 5-10 years?
But as for swaping the 8's; the saying goes; Only Time Will Tell.

Love it, I accept all the blame. I've never been a hard core fan. My brother had 301, which didn't impress me all that much. Never heard the 201, or any other Bose besides my 901 speakers, but they're the only ones I took seriously and wanted since I was a teen. I have a set of 501, but they are in a very sad way. I just need replacement woofers (long story).It's all your fault, man!

Like I said, hope to someday snag a pair of 601 myself.
5 or 10 years? Figure double that.
And I'd leave the batting inside. Boomy standing waves aren't good, and I know a thing or two about guitars/amplification, since I've worked for Gibson Guitars and built my own recording studio. The disciplines have similiar rules, but different desired outcomes.
I hope they sound great for you. Hopefully, those will drop right in and sound fantastic.
I was never a fan, either.
Until....
Should I ever see any 501 woofers for sale, I'll give you a shout, for sure. Always liked those at the hifi shop I worked as a 25 year old.

In many drier areas mabey; Here in Southern Ontario we spend almost half the year at above 60 % humidity, four of those months commonly reach averages of 80 % humidity.
Kentucky, I believe, has more favorable conditions to foam life and resiliancy.
But, Thank You. I'll let you know how they do once dropped in.
BTW: On that regard. How would one broadcast such results; So if successful, others may benifit?

Post here or start your own thread. People like images and narration, so if you're up to it, others will appreciate it.
Can't wait to hear (read) how it all works out.

Bose 601 project-
Not sure if we have a dedicated Bose area, but I'm wanting to build up/update/upgrade a pair of Bose 601 series II cabinets. I picked up one complete cab, but both woofers have been replaced. The 4 tweeters are intact and in great shape & sound. The 601 series I & II were my favs and I thought I'd take it upon myself to score some and see what others have done with theirs'....
