What size room are the KLH Model Five and JBL L82 Classic speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.
Drivers
One of the fundamental differences between these two speakers is that Model Five is a 3-way design whereas the L82 Classic is a 2-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

Model Five features a 1" aluminum Hard-Dome Tweeter, a 4" Midrange and 1 x 10" Pulp-Paper Woofer with a Crossover frequency at 380Hz and 2850Hz. On the other hand, the L82 Classic features a 1" Titanium Dome Tweeter and 1 x 8" Pulp Woofer with a Crossover frequency at 1700Hz.
Frequency Response
Model Five has a frequency range of 42-20k Hz whereas L82 Classic has a frequency range of 44-40k Hz. With a minimum frequency of 42Hz, the Model Five can go slightly deeper then the L82 Classic's min frequency of 44Hz.
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
Model Five is a 6 ohms speaker compared to the L82 Classic which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Model Five sensitivity is rated at 90.5 dB and the L82 Classic's is rated at 88 dB. This 3 dB difference makes the KLH Model Five a more sensitive speaker compared to JBL L82 Classic, hence will play louder with the same amount of watts.
Sensitivity
Floor-standing Speakers
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.
Model Five can handle a max power of 200 watts RMS, whereas L82 Classic has a max power handling value of 125 watts RMS, 75 watts less than the Model Five.
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.

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
Model Five features Five-way gold-plated binding posts type posts and L82 Classic has a Five-way gold-plated binding posts type posts. None of these speakers feature bi-amping/bi-wiring.

Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare KLH Model Five's and JBL L82 Classic's external dimensions. KLH Model Five has external dimensions of 870.0 x 350.0 x 330.0mm (34-1/4 x 13-3/4 x 13inch) whereas JBL L82 Classic has external dimensions of 472.8 x 281.0 x 315.5mm (18.6 x 11.0 x 12.4inch).
KLH Model Five is clearly the larger of the two speakers. Its body is 69mm wider, 397.2mm taller and 14.5mm deeper than JBL L82 Classic.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the KLH Model Five is approximately 1155.0cm2 / 179.0inch2 and base area of the JBL L82 Classic is approximately 886.6cm2 / 137.4inch2. The Model Five requires 30% more surface area than the L82 Classic which gives it a small disadvantage on placement in tight spaces.
