Hi again Bill,
Here are some pictures.
This system is very dynamic, precise and analytic. Every instrument is reproduced with astonishing realism. No detail is hidden. TAD compression drivers with Beryllium diaphragms are among the best that money can buy. The use of the AH Horns added smoothness and a clearer articulation to the sounds that the TAD reproduced. In fact I tried many horns in the 800 Hz to 12 KHz range, the most important part of the audible spectrum, and none did better then the AH horns (...yet...). Period.
My main sound source is an Oracle Delphi turntable with an Alphason tonearm. A Shure V15 type V cartridge is mounted on the arm and connected to a Hiraga phono preamp. A Krell preamplifier then sends the signal to a pair of modified Rane AC23 electronic crossovers. All the speakers used have a dedicated amplifier. Its a five way active system.
The lowest frequencies are reproduced by 2 JBL 2235H (15" speakers) mounted in an Onken enclosure tuned to 25 Hz. A bridged Bryston 4B SST amplifier is used here.
My satellite speakers are all horns. Bass is taken care of by 4 Altec Lansing 515B speakers mounted by pairs in a modified JBL 4550KBA cabinet. Two Basic M2A Kenwood amplifiers, with sigma drive circuit, are use here.
Mid frequencies are reproduced by a pair of JBL 2482 compression drivers. The original phenolic diaphragm were replaced by Radian diaphragms. Those drivers are bolted to a JBL 2350 horn.
Mid high frequencies are taken care of by a pair of TAD 4002 drivers married to AH horns (in fact this is the cherry on the sundae...).
High frequencies are reproduced by Fostex T-925 horn tweeters.
Mid and high frequencies are all amplified by Basic M1 Kenwood amplifiers, with sigma drive.
My system was adjusted (in the listening room 33' X 18') with a real time spectrum analyzer using 1/3 octave equalizers.
Best regards,
Maurice Daignault
