History
What size room are the JBL L100 Classic MKII 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 L100 Classic MKII 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.

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 L82 Classic features a 1" Titanium Dome Tweeter and 1 x 8" Pulp Woofer with a Crossover frequency at 1700Hz.
Frequency Response
L100 Classic MKII has a frequency range of 40-40k Hz whereas L82 Classic has a frequency range of 44-40k Hz. With a minimum frequency of 40Hz, the L100 Classic MKII 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 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 is a 4 ohms speaker compared to the L82 Classic which has a nominal impedance of 8 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the L100 Classic MKII can provide this impedance level.
These two speakers also have different sensitivity levels. L100 Classic MKII sensitivity is rated at 90 dB and the L82 Classic's is rated at 88 dB. This 2 dB difference makes the JBL L100 Classic MKII a more sensitive speaker compared to JBL L82 Classic, 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.
L100 Classic MKII 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 L100 Classic MKII.
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
L100 Classic MKII features Five-way gold-plated binding posts posts which make bi-amping or bi-wiring possible. L82 Classic has a Five-way gold-plated binding posts which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both L100 Classic MKII and L82 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 L82 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 L82 Classic has external dimensions of 472.8 x 281.0 x 315.5mm (18.6 x 11.0 x 12.4inch).
JBL L100 Classic MKII is clearly the larger of the two speakers. Its body is 108.6mm wider, 163.7mm taller and 56mm deeper than JBL L82 Classic.
Below you can see the front view size comparison of JBL L100 Classic MKII and JBL L82 Classic in scale.

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 JBL L100 Classic MKII is approximately 1447.4cm2 / 224.3inch2 and base area of the JBL L82 Classic is approximately 886.6cm2 / 137.4inch2. The L100 Classic MKII requires 63% more surface area than the L82 Classic which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The JBL L100 Classic MKII weighs 28.60kg / 62.9lbs and the JBL L82 Classic weighs 12.80kg / 28.2lbs. This makes the L100 Classic MKII 123% heavier than the L82 Classic.
Here is a comparison of how L100 Classic MKII and L82 Classic's weights compare with the average, max and min weights in Passive Bookshelf class.

Siblings in JBL's L Classic series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | JBL L100 Classic MKII digs deeper - 40Hz against 44Hz. A subwoofer would even that out. |
| Amplifier needs | A | JBL L100 Classic MKII is more sensitive (90dB vs 88dB), so it goes louder on the same amplifier. |
| Amplifier match | B | JBL L82 Classic is the easier load at 8 ohms; the other is 4 ohms and wants an amplifier rated for it. |
| Headroom | A | JBL L100 Classic MKII takes more power (200W vs 125W) - more in hand in a big room. |
| Size | depends | JBL L82 Classic is easier to place; JBL L100 Classic MKII is bigger, which usually goes with fuller bass. Your room decides. |
| Expandability | A | JBL L100 Classic MKII: bi-amping. |
| Price | B | JBL L82 Classic is cheaper - $2,750 against $4,800, about 43% less; arguably a different class. |
A JBL L100 Classic MKII B JBL L82 Classic
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: JBL L100 Classic MKII measures better, JBL L82 Classic costs about about 75% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. In a large or open-plan room, JBL L100 Classic MKII has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, JBL L82 Classic is the easier speaker to get right. If your amplifier is modest, vintage or valve-based, JBL L100 Classic MKII is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
