Man, now I miss those old Jensens and my '76 Camaro too (not quite stock, of course
I realize that details fade with time and that it may be human nature to romanticize things from the past, however, to keep with the car analogy, I'll bet anyone that has driven a muscle car remembers quite a few of the pros and cons. The heavy smell of gasoline, the erratic idle caused by the oversized cam, the kick in pants when the secondaries opened up, and in some cases the whine of supercharger. Maybe perception has a lot to do with it, but I think there are some unforgettable qualities about old cars and old speakers. No doubt today's cars are better in many ways, but there are some qualities that the old Jensens had that I can't find in any of today's speakers.
To me, the old Jensens seemed to blend the bass, mids, and highs very well. I remember them sounding very natural. This is something that I've had a difficult time finding in today's speakers, granted I have not listened to Triad yet.
I'm not exactly sure how speaker technology has advanced over the years, but even reaching back to the mid 90's, I had a pair of Altec Lansing speakers (picture attached) that provided the bass and the blending that I've been looking for in a new speaker. The over all sound quality wasn't the best though.
Today I have Definitive Technology BP7002's as my mains (pic attached). They do a descent job with the bass, but there seems to be a "hole" between the bass and the mids. I don't think that they blend the frequencies very well (IMHO).
After looking around the net for a while I found some companies like Wilson Audio that use larger woofers in some of their products. I don't know if these newer speakers with the larger woofers would provide the sound I am looking for, or what the benefit of these integrated woofers over a sub/sat system might be. I'll most likely never find out because of the price tag. I doubt they'd even let me in the door at a place were they sell equipment like that.
