Ultra Tower features a 1.0" aluminum Dome Tweeter , a 6.5" Midrange and 2 x 8.0" Polypropylene Woofer with a Crossover frequency at 160HZ and 2000Hz. On the other hand, the Forte IV features a 1" titanium-diaphragm compression horn-loaded Tweeter , a 1.75" Midrange and 1 x 12" Fibercomposite Woofer .
Frequency Response
Ultra Tower has a frequency range of 28-32k Hz whereas Forte IV has a frequency range of 38-20k Hz. With a minimum frequency of 28Hz, the Ultra Tower can go significantly deeper on the low side and provide stronger bass compared to the Forte IV's min frequency of 38Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

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 Tower and Forte IV have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Ultra Tower sensitivity is rated at 88 dB and the Forte IV's is at 99 dB. This 11 dB difference makes the Klipsch Forte IV a more sensitive speaker compared to SVS Ultra Tower, 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 Tower can handle a max power of 300 watts RMS from the amp the whereas Forte IV has a max power handling value of 100 watts RMS, 200 watts less than the Ultra Tower.
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 Tower and Forte IV features dual binding post speaker terminals for bi-amping or bi-wiring.

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 Tower's and Klipsch Forte IV's external dimensions. SVS Ultra Tower has external dimensions of 1159.0 x 355.0 x 445.0mm ( 45-5/8 x 13-15/16 x 17-1/2inch) whereas Klipsch Forte IV has external dimensions of 909.0 x 423.0 x 331.0mm ( 35-3/4 x 16-5/8 x 13inch) .
Klipsch Forte IV is 250mm shorter and 114mm less deeper than SVS Ultra Tower but it is also 68mm wider.
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 Tower is approximately 1579.8cm2 / 244.9inch2 and base area of the Klipsch Forte IV is approximately 1400.1cm2 / 217.0inch2. The Ultra Tower requires 13% more surface area than the Forte IV which gives it a small disadvantage 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 Tower weighs 34.27kg / 75.4lbs and the Klipsch Forte IV weighs 32.73kg / 72lbs. This makes the Ultra Tower 5% heavier than the Forte IV.
Here is a comparison of how Ultra Tower and Forte IV's weights compare with the average, max and min weights in Passive Floor-standing class.
