Installed new foam surrounds in these for a friend.
Easy job as the bass/mid cone self-supported firmly on its rear suspension and I had no need to remove the dust cap to use shims.
Sounded excellent when finished. P.S. I left the tweeter's series film capacitor and ceramic resistor alone!

I have in past did one, also a 301 from a friend, then, I did fall in love, not the friend but the 301,s
I have also a build sub now a closed system with shelf filter (active) goes not into the 130dB but 110 dB is feasable with the long range 12 inch. go from 22 Hz and up, do sound well, nice bass and not big, it fires down over the floor.

So you're a 301 veteran! I'd have happily held on to the 301s I renovated, but my friend insisted on having them back! They were the Series II with the twin opposing tweeters. Being direct/reflecting speakers they require careful positioning, but this is rewarded by a rich vintage sound. Nice work on the sub by the way!
Ì'm not a 301 veteran persé, there much more very good systems like horns, but these do sound very good for a normal box, I have the series II also with twin tweeters, unfortanely I miss a plastic cap between the tweeter and woofer were Bose letters are, not easy to find. I do like also old stuff, mine thinking about it is durable, I like to keep stuff alive, good for the environment also, Diyaudio is also such a forum, using old things to make something new, like tube/mosfet hybrides.

I'm still using the Rogers valve amp and Wharfedale 12" drivers I bought as a student over 50 years ago - they are on target to outlive me!
I just hope they will find a new home and provide further years of use after I have ascended to the great hi-fi emporium in the sky!

I hope you stay with us for years to come, some people get very old, maybe you need a bigger amp later on because hearing get less.
My first set of speakers were Bose 901's. We lived next to a military base and a young airman bought a set (over a $1000 back in '79). He got transferred and decided to sell them. Bought them from him pretty cheaply. Funny thing is I had them in a mobile home for a year...the speakers were worth more than the mobile home LOL. I was 20 and living the good life.
Here are some photos of the re-foaming process to inspire you.
Well I have mine done now, new foam in it, one mistake, I did lost one foam, but found it back later, One speaker has a double re-foamed.

Thanks for the update.
The speakers are now good for another 45 years of happy listening!
Unfortanely possible I do not go that long anymore. After 45 years I am 105, and the ears ringing like hell and dom.
All have I to say with mine 63 years, bloodpressure is still from that of a young guy with 113 over 72 and 59 heartbeats.
Not bad ehhh.
I can just about match that - provided I keep taking my medication!
I have no medication, I do never go to doctor, I do eat well, little meat, much fruit and Vegetables.
Meat is the most caused source.
So I live, if I do not get electrocuted.
It did not rise pressure but did rise the hair on the arms of mine.
And I have to find a better replecement for google chrome, it crashes and hangs a lot, and soooo slow.

Oke I have upload some sound after recone the two bose 301, I have include a subwoofer closed box with shelving 12 incher, get t0 20/25 Hz
Do not be shocked by the hard click you hear in the beginning, that is a revox taperecorder starting the music.
Sound is sometimes somewhat overmodulated (cracking with much bass) I think camera is a little sensitive, but it does nicely the very low frequencies.
The music is playing with the tube/mosfet hybrid I had design 15 years ago, no feedback dc coupled to mosfets and controlled by a servo. The bass
is quite clean with a closed box and have punch, but also when very low in the 20's it let shake things.

But I need to buy a stereo mic recorder some day, and a good one, tips welcome, not to expensive also.
