The JBL 4670D (http://www.jblpro.com/pages/cinema/4000.htm) from their cinema series is a large format system that happens to make a dynamite hi-fi system if you have the room to let them breathe. My dad wanted to update the speakers in his cabin which consists mostly of a large 40X25 room with high ceilings. He felt that the LF and HF extension from the old Stephens speakers you see below were just not up to the job. Finding new diaphragms, reconing, regaussing the magnets, and rebuilding the crossovers was just more than he wanted to deal with at his age, so I said “put ‘em on eBay and buy new ones.” After some 18 hours on eBay, some cat from Korea asked me how much I would want to end the auction; I hesitated for a minute and said $4000, and he said “sold!” He paid for crating and for BAX Global to pick them up and away they went.
Anyway, I got a hold of a local cinema contractor and ordered a pair (a separate franchise from JBL Pro; the sound reinforcement and musical instrument guys can’t get these). The price: a very reasonable $3000 including shipping.
With 100 db sensitivity, these things absolutely sing with his 35 watt Marantz triode amps. Dynamics are thunderous. HF extension is very nice, perhaps a little more laid back than my 4425’s or L-300s. Transients from gut strings on an classical gutiar are both powerful and delicate, This is my first experience with a 500hz horn, and for the first time I appreciate what those Altec 511 guys are talking about. Talk about liquid mids! I did not have enough time to evaluate them in the 75 watt pentode mode, they might have been even more impressive. To top it off , my dad had room to add some small bookcases with the left over space in the soffuts, as you can see from the photo below. I still have to work out some speaker grills however.
Why more HT contractors aren’t using these in custom home installations, is beyond me. I'm sure those Project Array 1400's are very nice speakers, but they're probably more than $3000 delivered.
