Acoustic Suspension sound in 2020?

I really like the sound of the 1960's-1970's acoustic suspension speakers owning a pair of AR-11's.

For a second installation, two questions for you folks who know far more than I--
- First, what if any new speakers have a similar sound?
- Second, any thoughts on KLH 5 and 6 vs. Large Advents vs. AR-3/11 and/or others?

Budget--I'll figure out later...if ideas are expensive, why not have a lust list to go with the purchase short list???!!!

Thanks very much!
