Installed the P660c in our Honda Odyssey (mids in stock location, tweeters in the A-pillars), replacing the DLS RS6A. Without tuning (all flat) and the crossovers at -6db with the high ear-level tweeters, the JBLs immediately sounded more dynamic with a powerful midbass. Tweeters angled at 45 degrees L and 20 degrees R from the driver, crossfiring. RTA showed an amazingly flat response from 150Hz to 4Khz, sloping downward at -6db/octave to 15Khz.
Tonight I compensated with a 10Khz wide-Q boost, now showing a nice -4db/octave slope in the higher treble. Did some tweaking with the sub level and sat back amazed. Before, my reference system were the Dayton RS180/Vifa NE19VTS combo running active in my other car. But these JBL P660c with the passives are every bit as dynamic, can take the full 75 watts and sound clear and linear with the added power (problem with the DLS -- power compression issues). Read in a Russian review of the European version of the P660c that they found the mid-high distortion levels to be very low and I believe that.
More pluses -- versatile mounting hardware (esp like the tweeter mounts), shallow depth (2.25"), and the use of air inductors in the Xovers.
Now I am thinking to try to run these P660c active, but for now I am greatly enjoying these budget components....
these were midbass monsters while they lasted.
the surrounds separated from the cone on both of my mids and one of my roommates set. i was sending mine signal from two channels of my memphis belle(115watts @ 2ohms) and they only lasted approx. 7 months. the tweet from this set is very laid back and pleasant during long listening sessions. not as detailed as some of the other tweets i have had, but i liked them very much.
it's a real shame that the mids destroyed themselves as i liked the midbass they delivered.
any ideas on how i might go about repairing the mids' surround, or are they doorstops now?
Ya I know its an old thread but happy it was hear to read about the JBL's but I recently had this happen with my Image Dynamics and I used double sided carpet tape between the frame and the woofer, then put a small amount of duck tape on top, lol, ikr but damn they sound better then when new.
