None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
S 81 CEN and S 801 has the same power range of up to 60 watts.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
S 81 CEN features Post type posts and S 801 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Both S 81 CEN and S 801 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
Size of a speaker can sometimes become 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 801'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 801 has external dimensions of 285.0 x 156.0 x 163.0mm ( 11.2 x 6.1 x 6.4inch) .
Jamo S 801 is 279mm narrower and 58mm less deeper than Jamo S 81 CEN but it is also 99mm taller.
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 801 is approximately 254.3cm2 / 39.4inch2. The S 81 CEN requires 278% more surface area than the S 801 which gives it a small disadvantage on placement in tight spaces.
