La Scala AL5 features a 1" polyimide diaphragm compression horn-loaded Tweeter , a 2" Midrange and 1 x 15" fiber-composite cone with folded horn Woofer . On the other hand, the R700 features a 1" Pinnacle Ring Radiator Tweeter , a 6.5" Midrange and 2 x 8" Polypropylene Woofer with a Crossover frequency at 350Hz and 2700Hz.
Frequency Response
La Scala AL5 has a frequency range of 51-20k Hz whereas R700 has a frequency range of 38-38k Hz. With a minimum frequency of 38Hz, the R700 can go significantly deeper on the low side and provide stronger bass compared to the La Scala AL5's min frequency of 51Hz.
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
La Scala AL5 and R700 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. La Scala AL5 sensitivity is rated at 105 dB and the R700's is at 88 dB. This 17 dB difference makes the Klipsch La Scala AL5 a more sensitive speaker compared to Polk R700, 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.
La Scala AL5 can handle a max power of 300 watts RMS from the amp the whereas La Scala AL5 has a max power handling value of 100 watts RMS , 200 watts less than the R700.
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 La Scala AL5 and R700 features dual binding post speaker terminals for bi-amping or bi-wiring.

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 La Scala AL5 is approximately 3960.9cm2 / 613.9inch2 and base area of the Polk R700 is approximately 1373.6cm2 / 212.9inch2. The La Scala AL5 requires 188% more surface area than the R700 which gives it a small disadvantage on placement in tight spaces.
