Bose 301- improvements and alterations.

cyteen · 25th June 2004, 01:49 PM

I was hoping to alter some Bose 301 series 3 speakers to try and get some music out of them. Looking at the tweeters, they have to go. I thought that maybe some tangband 871s instead.

The direct/reflecting thing doesn't fit with my understanding of soundfield reproduction so I thought one could face forward with the other facing back to compensate for bafflestep.

I would like suggestions for replacement long-throw drivers for the bass available in the UK. I don't want to spend too much, but theres no reason to be quite as cheap as Bose was in the first place.

Your chasing your tail bigtime here.
The tweeters don't get anywhere near baffle step frequencies,
The bass unit is OK, certainly not cost effective to replace it.

Sell them and buy some decent secondhand speakers.

you can polish a turd, but its still a turd.

Before anyone else turds on your idea, is there a reason you wish to start with that cabinet? After you replace the woofer, tweeters, crossover, binding posts and damping material, you might well have built yourself a real speaker. One that was designed for the new drivers.

Just my 2 cents

Thanks for the replies, they do confirm what I personally think, but I friend has a pair and so I thought that I would try some alterations to get them going in the right direction.

Putting aside the Bose designand parts and construction material issues, the size of the speaker seems to be as big as many would like to go. So I was thinking that I could throw together the tangbands and a bass driver and get something more listable. Then I came across a spare pair of 301's and thought I'd try from there.

I'll be sticking these in the local paper and starting from scatch. But I could still use suggestions for a similar sized project with the goal of being able to convert my friend from his Bose without breaking the bank.

Sadly the Bose are still better than many of the speakers owned by other friends so I might be making a few pairs.
