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 Model Five features a 1" aluminum Hard-Dome Tweeter , a 4" Midrange and 1 x 10" Pulp-Paper Woofer with a Crossover frequency at 380Hz and 2850Hz.
Frequency Response
Ultra Tower has a frequency range of 28-32k Hz whereas Model Five has a frequency range of 42-20k 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 Model Five's min frequency of 42Hz.
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.
Low Frequency

High Frequency
Floor-standing Speakers
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 is a 8 ohms speaker compared to the Model Five which has a nominal impedance of 6 ohms.
These two speakers also have different sensitivity levels. Ultra Tower sensitivity is rated at 88 dB and the Model Five's is rated at 90.5 dB. This 3 dB difference makes the KLH Model Five 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 Model Five has a max power handling value of 200 watts RMS, 100 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
Ultra Tower features Binding post posts which make bi-amping or bi-wiring possible. Model Five has a Binding post which doesn't feature bi-amping/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 KLH Model Five'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 KLH Model Five has external dimensions of 660.0 x 350.0 x 292.0mm ( 34-1/4 x 13-3/4 x 13inch) .
SVS Ultra Tower is clearly the larger of the two speakers. Its body is 5mm wider, 499mm taller and 153mm deeper than KLH Model Five.
Below you can see the front view size comparison of SVS Ultra Tower and KLH Model Five 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 Tower is approximately 1579.8cm2 / 244.9inch2 and base area of the KLH Model Five is approximately 1022.0cm2 / 158.4inch2. The Ultra Tower requires 55% more surface area than the Model Five which gives it a small disadvantage on placement in tight spaces.
