Mohan notice that i said *OLD* JBL's. new ones are fine speakers with good efficiency, extended response both in the lows and the highs. i don't think that phase linearity is as good as some of the best so imaging suffers somewhat, but many people would not notice either because of quality of source material or transducers. OLD JBL speakers are another story. it was not unusual to have a measured listing room peak of some 20 dB below 250 Hz and a high frequency peak of up to 10 dB around 12 to 14 kHz and a rapid roll off above 16 kHz. in between was nowhere near flat either, and phase was a word that was barely heard of in the speaker design business. to say that they were less than accurate is an understatement. of course, there were literally hundreds of speakers like them at the time. the origins of the terms 'west coast' and 'east coast' sound came about because of the comparisons between the two types of speakers that were commonly available at the time. the west coast sound was typified by JBL and Altec-Lansing speakers. the east coast sound was literally created by Advent. springing from people who left Advent were companies like Allison, Acoustic Research, and Boston Acoustics. west coast speakers were known as "rock" speakers because of the punch in the bass and sizzle on the high end. east coast speakers were synonymous with classical music tradition. while the fallacy is still propogated by some dealers, speaker systems in general today are much better systems than only ten years ago. there is really no such thing as a rock speaker or a classical speaker except with respect to efficiency and power handling. a speaker that reproduces all music the best is the best speaker.
