One sonic aspect as heard via some of the vintage speaker designs, their reproduction of bass compared to modern designs, gets an interesting comment in below quote.

I can attest to the merits of vintage designs incorporating large bass units and their supposed "musical" imprinting. My recently acquired all-horn loaded speakers use 15" bass drivers in folded horns, and are a pretty radical departure from my previous bass reflex-loaded speakers in providing what can actually be described as timbre and tunefulness in the bass with a seamless blend to the mid horn above them. They are specified to reach 56Hz only, a likely reason why many an interested audiophile would probably discount them prior to any audition, but the physicality, effortless power, speed and gently pressurized "wavefront" here presented is so tunefully imbedded in the remaining frequency spectrum above that it makes any preoccupation with bass extension per se seem utterly misplaced. I didn't know that prior to listening to them and how much the quality (and type) of bass could truly matter, so much indeed as to come to eschew most of what I've heard of the typical bass in modern designs with smaller (usually reflex loaded) drivers. I can still enjoy such more modern bass designs for what they are, but it's with the proviso that I probably wouldn't want to own them.
[...] all this talk about bass started me thinking about some of the speakers I have reviewed and listened to at audio shows in the last couple of years. A few came to mind: the Burwell & Sons Homage speakers, the big JBL Everest, the incredible sounding RCA LC-1A LS-11 and those wonderful sounding Tannoy Golds mounted in a Jensen Imperial Cabinets turned upside down so that the empty horn part of the cabinet acted as a stand to raise the Tannoy Gold drivers to the right height. Those were in the Pass Labs room at the 2014 California Audio Show.
All of these speakers have several things in common. First, they are all based on or actually are speakers from the mid to late 50s. Second, none of them attempt to play down into the 20s, in fact some don’t make it below 45Hz. Third, they all have very large drivers, most of them have 15-inch bass drivers and the Quad ESL bass panels have around 500 square inches for each speaker. Lastly, while they don’t all sound the same in the bass they all sound wonderfully musical.
There seems to me to be something fundamentally different in the way these speakers play bass compared to modern speakers with their super dead cabinets and incredible fast, tight and really deep bass. While these speakers sound very impressive their bass just doesn’t flow within the performance like these older-design speakers. The bass on these newer speakers is definitely deeper, faster and has more slam, but they just don’t have the life in the bass that the more vintage designs do. All of the speakers above have incredible air and harmonics in the bass. You feel the bass. Yes, you feel the bass with the modern speaker as well, but differently. The bass from modern speakers with extremely dead cabinets has a very pistonic sound. To me, real music seldom sounds this way, occasionally rock music does, but it also often sounds purposefully distorted.
