What size room are the Focal Kanta No.2 and JBL HDI-3800 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision
factor. Here we have compared their suitability to various sizes of environments considering their size
and max power parameters:

Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual
listening experience changes depending on floor height, room shape, surface materials, listening
position, speaker locations, etc.)
In the following sections, we will get into more detail in order to better understand how the Focal Kanta No.2 and JBL HDI-3800 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 Kanta No.2 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.

Kanta No.2 features a 1.1" IAL3 Beryllium Hard-Dome Tweeter , a 6.5" Midrange and 2 x 6.5" Flax Woofer with a Crossover frequency at 260 Hz - 2700 Hz. On the other hand, the HDI-3800 features a 1" Tweeter and 3 x 8" Aluminum Woofer .
Frequency Response
Kanta No.2 has a frequency range of 35-40k Hz whereas HDI-3800 has a frequency range of 37-30k Hz. With a minimum frequency of 35Hz, the Kanta No.2 can go slightly deeper then the HDI-3800's min frequency of 37Hz.
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

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
Kanta No.2 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. Kanta No.2 sensitivity is rated at 91 dB and the HDI-3800's is rated at 92 dB. This 1 dB difference makes the JBL HDI-3800 a more sensitive speaker compared to Focal Kanta No.2, 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.
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
HDI-3800 features 5-way post posts which make bi-amping or bi-wiring possible. Kanta No.2 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
Kanta No.2 has a Front firing port whereas HDI-3800 has a rear firing ports.
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 Focal Kanta No.2's and JBL HDI-3800's external dimensions. Focal Kanta No.2 has external dimensions of 1118.0 x 321.0 x 477.0mm ( 44inch x 12-5/8inch x 18-3/4inch ) 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 17mm narrower and 56mm less deeper than Focal Kanta No.2 but it is also 25mm 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 Focal Kanta No.2 is approximately 1531.2cm2 / 237.3inch2 and base area of the JBL HDI-3800 is approximately 1279.8cm2 / 198.4inch2. The Kanta No.2 requires 20% more surface area than the HDI-3800 which gives it a small disadvantage on placement in tight spaces.
