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.
Ultra Bookshelf can handle a max power of 150 watts RMS from the amp the whereas S 803 has a max power handling value of 80 watts RMS, 70 watts less than the Ultra Bookshelf.
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
Ultra Bookshelf features 5-way post posts which make bi-amping or bi-wiring possible. S 803 has a Post which doesn't feature bi-amping/bi-wiring.
Cabinet Type and Port Position
Ultra Bookshelf has a rear firing port whereas S 803 has a front firing ports. Jamo S 803's front-firing port gives more flexibility in placement in regards to proximity to walls compared to SVS Ultra Bookshelf with its rear-firing port.
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 SVS Ultra Bookshelf's and Jamo S 803's external dimensions. SVS Ultra Bookshelf has external dimensions of 380.0 x 218.0 x 281.0mm ( 14-15/16 x 8-9/16 x 11-1/16inch) whereas Jamo S 803 has external dimensions of 353.0 x 191.0 x 252.0mm ( 13.8 x 7.5 x 9.9inch) .
SVS Ultra Bookshelf is clearly the larger of the two speakers. Its body is 27mm wider, 27mm taller and 29mm deeper than Jamo S 803.
Below you can see the front view size comparison of SVS Ultra Bookshelf and Jamo S 803 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 SVS Ultra Bookshelf is approximately 612.6cm2 / 95.0inch2 and base area of the Jamo S 803 is approximately 481.3cm2 / 74.6inch2. The Ultra Bookshelf requires 27% more surface area than the S 803 which gives it a small disadvantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:
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 SVS Ultra Bookshelf weighs 8.64kg / 19lbs and the Jamo S 803 weighs 5.40kg / 11.9lbs. This makes the Ultra Bookshelf 60% heavier than the S 803.
Here is a comparison of how Ultra Bookshelf and S 803's weights compare with the average, max and min weights in Passive Bookshelf class.
