Advent loudspeakers

In 1977 while a Senior in HS I bought a pair of the "New Advents". I own them to this day. They are in my basement and I play them while working out. The surrounds have been replaced twice. The last go-round I used Van L Speakerworks in Chicago and had the internal wiring and cross-overs upgraded at  nominal cost. I am using a Sansuii receiver I bought at the same time. My source downstairs is a Dennon DVR player. I discovered that that with modern decent quality IC's and SC, the sound is pretty darned good. Where they truly excel is in the bass to mid-bass region. It is lightning fast and taut. Yes, they are dated in terms of refinement, midrange and treble but they are still pretty darned good. They should not be overstated or understated. They are somewhere in that hinterland between mid-fi and high-end. They get rock and roll rhythm sections down pat. A bass guitar and a tom-tom sounds incredibly real-quick and tight. In summary, they are a classic much like a '69 Mustang. 

This thread made me listen a bit more intently to my Large Advents yesterday and there is a quality that is not present in most current-era speakers; different bass instruments appear to emanate from different depths within the general area of the speaker. It is not image depth or soundstage depth per se but it is a distinct quality. Where the speakers fall down a bit is in midrange and treble continuity. Male voices sound a bit too chesty and female voices tend to sound a bit disembodied. The treble at the very highest frequencies sound a bit shrill and tizzy. It is a very enjoyable speaker but yes, it is no longer high-end. Perhaps it never was. 
I watched that weird movie with Tom Cruise and Penelope Cruz last night, Vanilla Sky. Pretty sure Tom is seen driving a '69 Mustang repeatedly in the beginning stages of the movie. To me it is a classic just as something my dad advised me when I was a teenager-gray wool slacks with a medium lapeled blue blazer is always a classic.
