Passif 50 features a 1" titanium dome with ferrofluid and neodymium magnet Dome Tweeter and 1 x 6.5" cast aluminum basket, paper cone Woofer with a Crossover frequency at 1800Hz. 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
Passif 50 has a frequency range of 50-20k Hz whereas L82 Classic has a frequency range of 44-40k Hz. With a minimum frequency of 44Hz, the L82 Classic can go significantly deeper on the low side and provide stronger bass compared to the Passif 50's min frequency of 50Hz.
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
Passif 50 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. Passif 50 sensitivity is rated at 87 dB and the L82 Classic's is rated at 88 dB. This 1 dB difference makes the PSB Passif 50 a more sensitive speaker compared to JBL L82 Classic, hence will play louder with the same amount of watts.
Sensitivity

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.
Passif 50 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 Passif 50.
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
Passif 50 features 5-Way post 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.

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 PSB Passif 50's and JBL L82 Classic's external dimensions. PSB Passif 50 has external dimensions of 660 × 280 × 254mm (26 x 11 x 10-inch) whereas JBL L82 Classic has external dimensions of 472.8 x 281.0 x 315.5mm (18.6 x 11.0 x 12.4inch).
PSB Passif 50 is 1mm narrower and 61.5mm less deeper than JBL L82 Classic but it is also 187.2mm taller.
Below you can see the front view size comparison of PSB Passif 50 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 PSB Passif 50 is approximately 712.0cm2 / 110.4inch2 and base area of the JBL L82 Classic is approximately 886.6cm2 / 137.4inch2. The Passif 50 requires 20% less surface area than the L82 Classic which gives it a small advantage 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 PSB Passif 50 weighs 13.70kg / 30.1lbs and the JBL L82 Classic weighs 12.80kg / 28.2lbs. This makes the Passif 50 7% heavier than the L82 Classic.
Here is a comparison of how Passif 50 and L82 Classic's weights compare with the average, max and min weights in Passive Bookshelf class.

A generation apart: PSB Passif 50 is the newer design, against a 2018 model. Newer is not automatically better, but the older one is more likely to be discounted or near run-out.
| Area | Better | Why |
|---|
| Bass | B | JBL L82 Classic digs deeper - 44Hz against 50Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (89dB vs 88dB) - both want much the same power. |
| Amplifier match | B | JBL L82 Classic is the easier load at 8 ohms. |
| Headroom | A | PSB Passif 50 takes more power (200W vs 125W) - more in hand in a big room. |
| Size | depends | Similar cabinet size - neither is easier to fit. |
| Cabinet | depends | Passive Radiator vs Ported. |
| Expandability | A | PSB Passif 50: bi-amping. |
| Price | evenly matched | Much the same money ($2,499 vs $2,750 a pair). |
A PSB Passif 50 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?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 50Hz anyway, so judge these on the other rows instead.
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.
