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 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
La Scala AL5 has a frequency range of 51-20k Hz whereas La Scala AL6 has a frequency range of 40-19k Hz. With a minimum frequency of 40Hz, the La Scala AL6 can go significantly deeper on the low side and provide stronger bass compared to the La Scala AL5's min frequency of 51Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.
Low Frequency
Floor-standing Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
La Scala AL5 and La Scala AL6 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 La Scala AL6's is at 103 dB. This 2 dB difference makes the Klipsch La Scala AL5 a more sensitive speaker compared to Klipsch La Scala AL6, 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. Staying
within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.
La Scala AL5 and La Scala AL6 have the same power range of up to 100 watts.
Note that higher power handling does not make a speaker louder: that depends mainly on
sensitivity and impedance. The calculator below shows how loud each of these actually plays
on a real amplifier.

Starting with a popular amplifier — change it to the one you own, or any you are
considering, and watch both numbers move.
Input Type and Bi-Amping / Bi-Wiring
Both La Scala AL5 and La Scala AL6 features dual binding post speaker terminals for bi-amping or bi-wiring.

Physical Specs
The size of a speaker can sometimes be 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 La Scala AL5's and Klipsch La Scala AL6's external dimensions. Klipsch La Scala AL5 has external dimensions of 1016.0 x 616.0 x 643.0mm (40 x 24-1/4 x 25-5/16inch) 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 AL5 is 6mm narrower and 4mm less deeper than Klipsch La Scala AL6 but it is also 22mm taller.
Below you can see the front view size comparison of Klipsch La Scala AL5 and Klipsch La Scala AL6 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 Klipsch La Scala AL5 is approximately 3960.9cm2 / 613.9inch2 and base area of the Klipsch La Scala AL6 is approximately 4024.3cm2 / 623.8inch2. The La Scala AL5 requires 2% less surface area than the La Scala AL6 which gives it a small advantage 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 Klipsch La Scala AL5 weighs 91.36kg / 201lbs and the Klipsch La Scala AL6 weighs 93.18kg / 205lbs. This makes the La Scala AL6 2% heavier than the La Scala AL5.
Here is a comparison of how La Scala AL5 and La Scala AL6's weights compare with the average, max and min weights in Passive Floor-standing class.

Klipsch La Scala AL6 digs deeper - 40Hz against 51Hz. |
| Amplifier needs |
A |
Klipsch La Scala AL5 is more sensitive (105dB vs 103dB), so it goes louder on the same amplifier. |

depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 51Hz anyway, which makes the cheaper Klipsch La Scala AL5 much easier to justify. If your amplifier is modest, vintage or valve-based, Klipsch La Scala AL5 is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
