Drivers
One of the fundamental differences between these two speakers is that La Scala AL5 is a 3-way design whereas the HDI-3800 is a 2-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.

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 HDI-3800 features a 1" Tweeter and 3 x 8" Aluminum Woofer .
Frequency Response
La Scala AL5 has a frequency range of 51-20k Hz whereas HDI-3800 has a frequency range of 37-30k Hz. With a minimum frequency of 37Hz, the HDI-3800 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.

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
La Scala AL5 is a 8 ohms speaker compared to the HDI-3800 which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the HDI-3800 can provide this impedance level.
These two speakers also have different sensitivity levels. La Scala AL5 sensitivity is rated at 105 dB and the HDI-3800's is rated at 92 dB. This 13 dB difference makes the Klipsch La Scala AL5 a more sensitive speaker compared to JBL HDI-3800, 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 HDI-3800.
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 HDI-3800 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 La Scala AL5's and JBL HDI-3800'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 JBL HDI-3800 has external dimensions of 1143.0 x 304.0 x 421.0mm ( 45 x 11-15/16 x 16-9/16inch) .
JBL HDI-3800 is 312mm narrower and 222mm less deeper than Klipsch La Scala AL5 but it is also 127mm taller.
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 JBL HDI-3800 is approximately 1279.8cm2 / 198.4inch2. The La Scala AL5 requires 209% more surface area than the HDI-3800 which gives it a small disadvantage on placement in tight spaces.
