High Frequency
Bookshelf Speakers
SVS Ultra Evolution Bookshelf
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.
Impedance and Sensitivity
Ultra Evolution Bookshelf is a 6 ohms speaker compared to the HDI-1600 which has a nominal impedance of 4 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 HDI-1600 can provide this impedance level.
These two speakers also have different sensitivity levels. Ultra Evolution Bookshelf sensitivity is rated at 87 dB and the HDI-1600's is rated at 85 dB. This 2 dB difference makes the SVS Ultra Evolution Bookshelf a more sensitive speaker compared to JBL HDI-1600, 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. 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 Evolution Bookshelf can handle a max power of 200 watts RMS from the amp the whereas Ultra Evolution Bookshelf has a max power handling value of 150 watts RMS , 50 watts less than the HDI-1600.
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
Both Ultra Evolution Bookshelf and HDI-1600 features dual binding post speaker terminals for bi-amping or bi-wiring.
SVS Ultra Evolution Bookshelf's Gold-plated 5-way terminals allows Bi-amping or bi-wiring
JBL HDI-1600's 5-way post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Ultra Evolution Bookshelf and HDI-1600 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 SVS Ultra Evolution Bookshelf's and JBL HDI-1600's external dimensions. SVS Ultra Evolution Bookshelf has external dimensions of 382 x 220 x 295.6mm ( 11.14 x 8.66 x 11.64”) whereas JBL HDI-1600 has external dimensions of 383.0 x 232.0 x 289.0mm ( 15-1/16 x 9-1/8 x 11-3/8inch) .
SVS Ultra Evolution Bookshelf is 12mm narrower and 1mm shorter than JBL HDI-1600 but it is also 7mm deeper.
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 Evolution Bookshelf is approximately 651.2cm2 / 100.9inch2 and base area of the JBL HDI-1600 is approximately 670.5cm2 / 103.9inch2. The Ultra Evolution Bookshelf requires 3% less surface area than the HDI-1600 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 SVS Ultra Evolution Bookshelf weighs 8.60kg / 18.9lbs and the JBL HDI-1600 weighs 9.98kg / 22lbs. This makes the HDI-1600 16% heavier than the Ultra Evolution Bookshelf.
