Advent Baby II's gut and rebuild recommendations

I’m new to this speaker audiophile forum and new to the speaker rebuild/build world. I just recently decide to rebuild my 25 y.o. Cerwin Vega L-7 bookshelf speakers. Their new sound is amazing. Never thought I would get such great sound from these old CV’s. I ended up gutting them so there is basically nothing CV left in them except the cabinet and front cover and even then I had to cut the front panel off and replace it with a ¾” piece of MDF.

Anyway, my brother heard the difference in the before and after and he’s now itching to rebuild his Advent Baby II’s. As with my CV’s we’re open to gutting the entire speaker system and just using the cabinet to install the new components (woofer, tweeter, cross-over and hook ups).

Based on what we can tell these are approx .48 cubic feet in interior volume and a non-ported sealed cabinet design. The woofer cutout measures 5-1/2” diameter and the tweeter is 2-3/8” diameter. He’s planning to power them with an Onkyo TX-8222 (70 watts / channel) in a medium sized living room. As I mentioned we’re both new to this, i.e. not yet at the level to design our own cross-over’s but we plan to get there eventually :) so we’re looking for advice and recommendations for replacement components that will work good together in this cabinet.

Thanks in advance.

Good luck with your "project"! I have heard "resto-mods" sound really good, and, conversely, really bad. Just depends on if you find the "right match". Unfortunately, should you decide to pass them on (sell them), they have virtually no re-sale value, because they are now "home-brew/frankenspeakers", so I wouldn't dump a ton of money into them, unless they turn out to be "keepers".

Just out of curiosity--what is so "wrong" with the original drivers that they can't be used/repaired, rather than just swapping them out?

he actually has 3 sets of these, all stock. one set he's currently listening to and the other two sets that were given to him. the set we are going to rebuild has a torn woofer so we're ok with them being frankenspeakers (love that term :)). since we're new at this we'll use this pair as our "learning platform". we'll always keep one set stock as the "baseline" pair. We agree also that we don't want to dump a ton of money into them. We're looking for the best bang for the buck set-up. On my Cerwin Vega project I spent about $250 total - components, MDF board, screws, etc.
