In this review, we will be comparing BP-9020 and S 809, two Passive Floor-standing speakers from Definitive Technology and Jamo. Let's have a brief look at the main features
of Definitive BP-9020 and Jamo S 809 first before getting into our more
detailed comparison.
What size room are the Definitive BP-9020 and Jamo S 809 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:
In the following sections, we will get into more detail in order to better understand how the Definitive BP-9020 and Jamo S 809 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-9020 is a 3-way design whereas the S 809 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-9020 features a 1" annealed aluminum dome Tweeter , a 3.5" Midrange and 1 x 8" Polypropelene Woofer . On the other hand, the S 809 features a 1" Tweeter and 3 x 5" Aluminized Polyfiber Woofer with a Crossover frequency at 2000Hz.
Frequency Response
BP-9020 has a frequency range of 28-40k Hz whereas S 809 has a frequency range of 37-26k Hz. With a minimum frequency of 28Hz, the BP-9020 can go significantly deeper on the low side and provide stronger bass compared to the S 809'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.

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
BP-9020 and S 809 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. BP-9020 sensitivity is rated at 92 dB and the S 809's is at 90 dB. This 2 dB difference makes the Definitive BP-9020 a more sensitive speaker compared to Jamo S 809, hence will play louder with the same amount of watts.
Sensitivity

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.
BP-9020 can handle a max power of 200 watts RMS from the amp the whereas S 809 has a max power handling value of 120 watts RMS, 80 watts less than the BP-9020.
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
BP-9020 features Post type posts and S 809 has a Post type posts. None of these speakers 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-9020's and Jamo S 809's external dimensions. Definitive BP-9020 has external dimensions of 904.0 x 281.0 x 351.0mm ( 35-9/16 x 11-1/16 x 13-13/16inch) whereas Jamo S 809 has external dimensions of 1042.0 x 191.0 x 252.0mm ( 41.0 x 7.5 x 9.9inch) .
Jamo S 809 is 90mm narrower and 99mm less deeper than Definitive BP-9020 but it is also 138mm 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 Definitive BP-9020 is approximately 986.3cm2 / 152.9inch2 and base area of the Jamo S 809 is approximately 481.3cm2 / 74.6inch2. The BP-9020 requires 105% more surface area than the S 809 which gives it a small disadvantage 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 Definitive BP-9020 weighs 13.64kg / 30lbs and the Jamo S 809 weighs 13.60kg / 29.9lbs. This makes the BP-9020 0% heavier than the S 809.
Here is a comparison of how BP-9020 and S 809's weights compare with the average, max and min weights in Passive Floor-standing class.
