History
In the following sections, we will get into more detail in order to better understand how the Klipsch OJAS kO-R2 and Klipsch La Scala AL6 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Drivers
One of the fundamental differences between these two speakers is that kO-R2 is a 2-way design whereas the La Scala AL6 is a 3-way speaker. 3-way designs utilize a midrange driver in addition to the tweeter and woofer on 2-way designs. Designing a crossover for a 3-way speaker is a complicated process and generally increases the overall cost of the speaker.

kO-R2 features a " K-706 driver Compression Horn Tweeter and 1 x 15" Paper Woofer with a Crossover frequency at 760Hz. On the other hand, the La Scala AL6 features a 1" polyimide diaphragm compression horn-loaded Tweeter , a 3" Midrange and 1 x 12" fiber-composite cone with folded horn Woofer with a Crossover frequency at 425Hz - 2900Hz.
Frequency Response
kO-R2 has a frequency range of 39-20k Hz whereas La Scala AL6 has a frequency range of 40-19k Hz. With a minimum frequency of 39Hz, the kO-R2 can go slightly deeper then the La Scala AL6's min frequency of 40Hz.
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
kO-R2 and La Scala AL6 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. kO-R2 sensitivity is rated at 97 dB and the La Scala AL6's is at 103 dB. This 6 dB difference makes the Klipsch La Scala AL6 a more sensitive speaker compared to Klipsch OJAS kO-R2, 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.
kO-R2 can handle a max power of 300 watts RMS from the amp the whereas La Scala AL6 has a max power handling value of 100 watts RMS, 200 watts less than the kO-R2.
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
La Scala AL6 features Binding post posts which make bi-amping or bi-wiring possible. kO-R2 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 Klipsch OJAS kO-R2's and Klipsch La Scala AL6's external dimensions. Klipsch OJAS kO-R2 has external dimensions of 1156.0 x 645.0 x 565.0mm ( 45-1/2 x 25-3/8 x 22-1/4inch) whereas Klipsch La Scala AL6 has external dimensions of 994 x 622 x 647mm ( 39/1 x 24.5 x 25.5inch) .
Klipsch La Scala AL6 is 23mm narrower and 162mm shorter than Klipsch OJAS kO-R2 but it is also 82mm 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 Klipsch OJAS kO-R2 is approximately 3644.3cm2 / 564.9inch2 and base area of the Klipsch La Scala AL6 is approximately 4024.3cm2 / 623.8inch2. The kO-R2 requires 9% less surface area than the La Scala AL6 which gives it a small advantage on placement in tight spaces.
