Studio 690 features a 1" compression driver with HDI (High Definition Imaging) waveguide Tweeter and 2 x 8" PolyPlas Woofer. On the other hand, the Studio 6 88LCR features a 1" Horn-Loaded Tweeter and 2 x 8" PolyPlas Woofer.
Frequency Response
Studio 690 has a frequency range of 36-40k Hz whereas Studio 6 88LCR has a frequency range of 43-20kHz. With a minimum frequency of 36Hz, the Studio 690 can go significantly deeper on the low side and provide stronger bass compared to the Studio 6 88LCR's min frequency of 43Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Studio 690 and Studio 6 88LCR have the same Impedance of 6 ohms but where they differ is the sensitivity levels. Studio 690 sensitivity is rated at 90 dB and the Studio 6 88LCR's is at 96 dB. This 6 dB difference makes the JBL Studio 6 88LCR a more sensitive speaker compared to JBL Studio 690, hence will play louder with the same amount of watts.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
Studio 690 can handle a max power of 250 watts RMS, whereas Studio 6 88LCR has a max power handling value of 175 watts RMS, 75 watts less than the Studio 690.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.
Which plays louder on your amplifier?
Starting with a popular amplifier - change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Studio 690 features 5-Way post posts which make bi-amping or bi-wiring possible. Studio 6 88LCR has a Spring posts which doesn't feature bi-amping/bi-wiring.
