Advent/2 project -worth modifying?

I purchased this pair of Advent/2's from a thrift store a couple of years back. I am well aware of the lousy reputation these particular Advents have but I could not help myself when I noticed that they were in such good condition. I also saw some potential in these speakers considering the woofers do have a good reputation.

Should I just re-foam this set and pass them down the line as to retain the vintage integrity of the speakers (they aren't worth much anyhow) OR should I get another set of compatible tweets (and possibly have to modify the baffle) and just make them sound as good as possible? If the latter is suggested than any suggestions for new/used tweeters/crossovers? Thanks as always! :music:

Take the array off the baffle, and let's see what the opening looks like behind it, please.

Converting them to /3 might be an option, if the requisite info is available.

Does anybody know what the crossover frequency was?

I ask so as to ascertain how high the woofs will likely play.... :yes:
 
O.K., I see that the availability of correct surrounds for those is unknown at best, but a bit of effort at the known sources may turn them up:

What is the measurement between the two points of that cutout, the inside depth of the cabinet, and woofer outside diameter?

Worst case, if the cabs are in good shape, consider them a DIY project platform.... :yes:
 
The cutout from side to side measures 3". From top to bottom it is 5-1/2".

The cab is approx. 5-3/8" deep measured from the inside edge of the baffle.

The outside diameter of the speaker basket is 9-1/2".
 
It seems easy enough to fabricate a plate to install a dome tweeter.

Contact Rick Cobb, looneytune2001 on eBay, to see if he has the proper surrounds for those woofers....
 
Rick does not carry the correct size foam but I am waiting to hear back from parts express just make sure they have it. If I can't find the correct size anywhere I have read that a larger piece of foam can be modified to fit if need be.

Any suggestions for replacement tweeters?
 
"Notes:The advent /3 is a great small bookshelf that still has the classic look and sound. It uses the same cone tweeter as the model 2, but only one instead of two in an array."

Maybe it would be possible to use 2 out of the 4 tweets that came with these speakers? If we can come up with the original specs that is. Anyone have the specs for Advent 2 and/or 3's?
 
I had a pair of Advent/2 in lovely condition with perfect surrounds...I actually quite enjoyed their sound (wasn't incredible, but good enough). I think they would be great 'starter' speakers for many people.
 
"The suggested component values are .79mH for the coil and 7.24uF for the cap."

Excuse my ignorance but do you mean that I only need to replace all three caps with just one 7.24uF cap? Also I am assuming that the coil is the wrapped magnet on the right (see picture)?

how about making a plate for BOTH tweeters? mount them one above the other, flat on the baffle, as close to each other as possible. no change to the x-over needed. probably.
 
Advent 2 tweeter

Unfortunately, I passed a 10K tone through one set. It smoked, and stopped playing. I could make a plywood platefor each speaker, and just use one tweeter in each. I have read that this is what is in the Advent 3, and gets good results. I could clip, or tape the second set of tweeter wires fro each tweeter. Any thoughts?
How about a new tweeter with the same crossover?
