I was informed the reason most higher end Hifi speakers use a composite basket is because the steel baskets create an unwanted resonance to the trained ear. Is there anything I can do to my current steel baskets to reduce this resonance? I was thing of using thick double sided tape on the basket which I can cut to match.

Dont worry about résonance,  it is a flavor, alum also have its résonance,  however the prob is steel react with the magnet.

You can also use a butyl-based metal dampening product, like Dynamat, for the same effect.

FRM, aside from buying a slew of new woofers, is there anything that can be done about that?

I would not do anything. In the 1990s I had a 3M self adhesive alu tape so I rolled up an FR driver magnet, unfortunately there was no improvement in sound and it may lead to decreased magnet cooling.

I've always used non-hardening fingertip caulk. Works very well, a significant improvement in clarity and focus to my ears. Improvement is related to the added mass and damping, not adhesiveness of the material used. Caulk is pretty dense and heavy, but sticks well too, is cheap and found at most hardware stores.
Modeling clay has similar qualities.

Hi Hoobs. Read somewhere that Butyl are bad to the rubbers on the woofer cone. Is this correct?
Bought some and change to a “dynamite” look a like instead, to be sure. Overkill?

Duct-seal. I have been using it for 45 years. Dtuff i applied then us still reusable.

Dynamat is a butyl rubber based damper and i usually use look-alike products without any issue. It may cause issues if directly touching some rubbers, but if you just stick it onto the arms of fhe frame/basket and keep it away from the rubber it'll dampen out any resonances without damaging the surrounds.

Here's some on an old Technics woofer.



I put some foam dampener on this speaker as well but it was only to soften direct reflections rather than dampen the ringing. You can see the butyl stuff around the woofer and under the foam strips.
