L800 features a 1" Pinnacle Ring Radiator Tweeter , a 5.25" Midrange and 2 x 10" Polypropylene Woofer with a Crossover frequency at 370Hz and 2800Hz. On the other hand, the L400 features a 1" Pinnacle Ring Radiator Tweeter , a 4" Midrange and 2 x 6.5" Woofer .
Frequency Response
L800 has a frequency range of 32-38k Hz whereas L400 has a frequency range of 55-38k Hz. With a minimum frequency of 32Hz, the L800 can go significantly deeper on the low side and provide stronger bass compared to the L400's min frequency of 55Hz.
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
L800 and L400 have the same Impedance of 4 ohms but where they differ is the sensitivity levels. L800 sensitivity is rated at 87 dB and the L400's is at 87.5 dB. This 1 dB difference makes the Polk L400 a more sensitive speaker compared to Polk L800, hence will play louder with the same amount of watts.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the L800 and the L800 can provide this impedance level.

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.
L800 and L400 has the same power range of 25-300 watts.
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
L800 features Binding post posts which make bi-amping or bi-wiring possible. L400 has a Binding post which doesn't feature bi-amping/bi-wiring.

Cabinet Type and Port Position
L800 has a down firing port whereas L400 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 Polk L800's and Polk L400's external dimensions. Polk L800 has external dimensions of 1236.0 x 458.0 x 443.0mm ( 48-5/8 x 18 x 17-7/16inch) whereas Polk L400 has external dimensions of 245.0 x 662.0 x 343.0mm ( 9-5/8 x 26-1/16 x 13-1/2inch) .
Polk L400 is 991mm shorter and 100mm less deeper than Polk L800 but it is also 204mm wider.
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 Polk L800 is approximately 2028.9cm2 / 314.5inch2 and base area of the Polk L400 is approximately 2270.7cm2 / 352.0inch2. The L800 requires 11% less surface area than the L400 which gives it a small advantage on placement in tight spaces.
