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 Definitive BP-9080X 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 BP-9080X 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.

BP-9080X features a 1" annealed aluminum dome Tweeter , a 5.25" Midrange and 1 x 12" Polypropelene Woofer . On the other hand, the HDI-3800 features a 1" Tweeter and 3 x 8" Aluminum Woofer .
Frequency Response
BP-9080X has a frequency range of 16-40k Hz whereas HDI-3800 has a frequency range of 37-30k Hz. With a minimum frequency of 16Hz, the BP-9080X can go significantly deeper on the low side and provide stronger bass compared to 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.

Impedance and Sensitivity
BP-9080X 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.
On the other hand, they have the same sensitivity of 92 dBdB.

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. BP-9080X has a 5-Way post, RCA 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 Definitive BP-9080X's and JBL HDI-3800's external dimensions. Definitive BP-9080X has external dimensions of 1309.0 x 318.0 x 410.0mm ( 51-1/2 x 12-1/2 x 16-1/8inch) 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 14mm narrower and 166mm shorter than Definitive BP-9080X but it is also 11mm 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 Definitive BP-9080X is approximately 1303.8cm2 / 202.1inch2 and base area of the JBL HDI-3800 is approximately 1279.8cm2 / 198.4inch2. The BP-9080X requires 2% more surface area than the HDI-3800 which gives it a small disadvantage on placement in tight spaces.
