AK7 features a 1" polyimide diaphragm compression Tractrix horn Tweeter , a 3" Midrange and 1 x 15" fiber-composite with a trihedral exponential folded horn Woofer with a Crossover frequency at 380Hz - 290Hz. On the other hand, the F328Be features a 1" Tweeter , a 5.25" Midrange and 3 x 8.0" Aluminum Woofer .
Frequency Response
AK7 has a frequency range of 34-19k Hz whereas F328Be has a frequency range of 26-40k Hz. With a minimum frequency of 26Hz, the F328Be can go significantly deeper on the low side and provide stronger bass compared to the AK7's min frequency of 34Hz.
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
AK7 and F328Be have the same Impedance of 8 ohms but where they differ is the sensitivity levels. AK7 sensitivity is rated at 103 dB and the F328Be's is at 91 dB. This 12 dB difference makes the Klipsch Klipschorn AK7 a more sensitive speaker compared to Revel PerformaBe F328Be, 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.
AK7 can handle a max power of 300 watts RMS from the amp the whereas AK7 has a max power handling value of 100 watts RMS , 200 watts less than the F328Be.
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 AK7 and F328Be 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 Klipsch Klipschorn AK7's and Revel PerformaBe F328Be's external dimensions. Klipsch Klipschorn AK7 has external dimensions of 1347.0 x 794.0 x 718.0mm ( 53 x 31-1/4 x 28-1/4inch) whereas Revel PerformaBe F328Be has external dimensions of 1294.0 x 343.0 x 448.0mm ( 50-15/16 x 13-1/2 x 17-5/8inch) .
Klipsch Klipschorn AK7 is clearly the larger of the two speakers. Its body is 451mm wider, 53mm taller and 270mm deeper than Revel PerformaBe F328Be.
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 Klipsch Klipschorn AK7 is approximately 5700.9cm2 / 883.6inch2 and base area of the Revel PerformaBe F328Be is approximately 1536.6cm2 / 238.2inch2. The AK7 requires 271% more surface area than the F328Be which gives it a small disadvantage on placement in tight spaces.
