L100 Classic MKII features a 1" Titanium Dome Tweeter, a 5.25" Midrange and 1 x 12" Pulp Woofer with a Crossover frequency at 450Hz and 3500Hz. On the other hand, the L150 Classic features a 1" Titanium Dome Tweeter, a 6.5" Midrange and 1 x 15" Pure Pulp Woofer with a Crossover frequency at 300Hz and 1800Hz.
Frequency Response
L100 Classic MKII has a frequency range of 40-40k Hz whereas L150 Classic has a frequency range of 32-22k Hz. With a minimum frequency of 32Hz, the L150 Classic can go significantly deeper on the low side and provide stronger bass compared to the L100 Classic MKII's min frequency of 40Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf 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
L100 Classic MKII and L150 Classic have the same Impedance of 4 ohms but where they differ is the sensitivity levels. L100 Classic MKII sensitivity is rated at 90 dB and the L150 Classic's is at 88 dB. This 2 dB difference makes the JBL L100 Classic MKII a more sensitive speaker compared to JBL L150 Classic, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the L100 Classic MKII and the L100 Classic MKII can provide this impedance level.

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.
L150 Classic can handle a max power of 250 watts RMS, whereas L100 Classic MKII has a max power handling value of 200 watts RMS, 50 watts less than the L150 Classic.
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
Both L100 Classic MKII and L150 Classic features dual binding post speaker terminals for bi-amping or bi-wiring.
JBL L100 Classic MKII's Five-way gold-plated binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both L100 Classic MKII and L150 Classic have front firing ports. front ported speakers offers more flexibility in placement in regards to proximity to walls&surfaces compared to rear ported speakers.
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 JBL L100 Classic MKII's and JBL L150 Classic's external dimensions. JBL L100 Classic MKII has external dimensions of 636.5 x 389.6 x 371.5mm (25.0 x 15.3 x 14.6inch) whereas JBL L150 Classic has external dimensions of 935.0 x 470.0 x 540.0mm (36.8 x 18.5 x 21.3inch).
JBL L150 Classic is clearly the larger of the two speakers. Its body is 80.4mm wider, 298.5mm taller and 168.5mm deeper than JBL L100 Classic MKII.
Below you can see the front view size comparison of JBL L100 Classic MKII and JBL L150 Classic in scale.
