S 81 CEN and S 83 CEN are members of Jamo's Studio 8 series of speakers. Below you can find the loudspeakers from this series.
What size room are the Jamo S 81 CEN and Jamo S 83 CEN 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:

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
Both S 81 CEN and S 83 CEN are 2-way speakers.

S 81 CEN features a 1" soft dome with an integrated waveguide Tweeter and 2 x 4" polyfiber Woofer with a Crossover frequency at 2000Hz. On the other hand, the S 83 CEN features a 1" soft dome with an integrated waveguide Tweeter and 2 x 5" polyfiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
S 81 CEN has a frequency range of 71-26k Hz whereas S 83 CEN has a frequency range of 65-26k Hz. With a minimum frequency of 65Hz, the S 83 CEN can go significantly deeper on the low side and provide stronger bass compared to the S 81 CEN's min frequency of 71Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Center Channel class in our database.
Low Frequency
Center Channel 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
S 81 CEN and S 83 CEN have the same Impedance of 8 ohms but where they differ is the sensitivity levels. S 81 CEN sensitivity is rated at 86 dB and the S 83 CEN's is at 87 dB. This 1 dB difference makes the Jamo S 83 CEN a more sensitive speaker compared to Jamo S 81 CEN, hence will play louder with the same amount of watts.
Sensitivity
Center Channel 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.
S 83 CEN can handle a max power of 80 watts RMS, whereas S 81 CEN has a max power handling value of 60 watts RMS, 20 watts less than the S 83 CEN.
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
S 81 CEN features Binding post type posts and S 83 CEN has a Binding post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both S 81 CEN and S 83 CEN have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Jamo S 81 CEN's and Jamo S 83 CEN's external dimensions. Jamo S 81 CEN has external dimensions of 186.0 x 435.0 x 221.0mm (7-5/16 x 17-1/8 x 8-11/16inch) whereas Jamo S 83 CEN has external dimensions of 216.0 x 499.0 x 247.0mm (8-1/2 x 19-5/8 x 9-11/16inch).
Jamo S 83 CEN is clearly the larger of the two speakers. Its body is 64mm wider, 30mm taller and 26mm deeper than Jamo S 81 CEN.
Below you can see the front view size comparison of Jamo S 81 CEN and Jamo S 83 CEN 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 Jamo S 81 CEN is approximately 961.4cm2 / 149.0inch2 and base area of the Jamo S 83 CEN is approximately 1232.5cm2 / 191.0inch2. The S 81 CEN requires 22% less surface area than the S 83 CEN 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 Jamo S 81 CEN weighs 5.00kg / 11lbs and the Jamo S 83 CEN weighs 6.80kg / 15lbs. This makes the S 83 CEN 36% heavier than the S 81 CEN.
Here is a comparison of how S 81 CEN and S 83 CEN's weights compare with the average, max and min weights in Passive Center Channel class.

Siblings in Jamo's Studio 8 series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | B | Jamo S 83 CEN digs deeper - 65Hz against 71Hz. A subwoofer would even that out. |
| Amplifier needs | evenly matched | Similar sensitivity (86dB vs 87dB) - both want much the same power. |
| Headroom | B | Jamo S 83 CEN takes more power (80W vs 60W) - more in hand in a big room. |
| Size | depends | Jamo S 81 CEN is easier to place; Jamo S 83 CEN is bigger, which usually goes with fuller bass. Your room decides. |
| Price | A | Jamo S 81 CEN is cheaper - $174 against $229, about 24% less. |
A Jamo S 81 CEN B Jamo S 83 CEN
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: Jamo S 83 CEN measures better, Jamo S 81 CEN costs about about 32% 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. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 71Hz anyway, which makes the cheaper Jamo S 81 CEN much easier to justify. Match it to your room: we rate Jamo S 81 CEN the better fit for near-field listening; elsewhere the two are rated the same.
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.
