3050i features a 0.9" decoupled Tweeter and 2 x 6.5" Coated paper Woofer with a Crossover frequency at 2500 Hz. 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
3050i has a frequency range of 44-30k Hz whereas S 809 has a frequency range of 37-26k Hz. With a minimum frequency of 37Hz, the S 809 can go significantly deeper on the low side and provide stronger bass compared to the 3050i's min frequency of 44Hz.
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.
Low Frequency

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
3050i is a 6 ohms speaker compared to the S 809 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. 3050i sensitivity is rated at 91 dB and the S 809's is rated at 90 dB. This 1 dB difference makes the Q Acoustics 3050i a more sensitive speaker compared to Jamo S 809, 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.
3050i can handle a max power of 175 watts RMS from the amp the whereas S 809 has a max power handling value of 120 watts RMS, 55 watts less than the 3050i.
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
3050i features Post type posts and S 809 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.

Cabinet Type and Port Position
3050i has a rear firing port whereas S 809 has a front firing ports. Jamo S 809's front-firing port gives more flexibility in placement in regards to proximity to walls compared to Q Acoustics 3050i with its rear-firing port.

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 Q Acoustics 3050i's and Jamo S 809's external dimensions. Q Acoustics 3050i has external dimensions of 1020 x 310 x 320 mm ( 40.2 x 12.2 x 12.6 in) 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 119mm narrower and 68mm less deeper than Q Acoustics 3050i but it is also 22mm taller.
Below you can see the front view size comparison of Q Acoustics 3050i and Jamo S 809 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 Q Acoustics 3050i is approximately 992.0cm2 / 153.8inch2 and base area of the Jamo S 809 is approximately 481.3cm2 / 74.6inch2. The 3050i requires 106% more surface area than the S 809 which gives it a small disadvantage on placement in tight spaces.
