What size room are the Polk L200 and Polk RTi A3 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 Polk L200 and Polk RTi A3 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

L200 features a 1" Ring Radiator Tweeter and 1 x 6.5" Polypropylene Woofer with a Crossover frequency at 2600Hz. On the other hand, the RTi A3 features a 1" silk polymer composite Dome Tweeter and 1 x 6.5" Polymer composite Woofer with a Crossover frequency at 2800Hz.
Frequency Response
L200 has a frequency range of 46-38k Hz whereas RTi A3 has a frequency range of 50-26k Hz. With a minimum frequency of 46Hz, the L200 can go slightly deeper then the RTi A3's min frequency of 50Hz.
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 Bookshelf 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
L200 is a 4 ohms speaker compared to the RTi A3 which has a nominal impedance of 8 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 L200 can provide this impedance level.
These two speakers also have different sensitivity levels. L200 sensitivity is rated at 85.5 dB and the RTi A3's is rated at 89 dB. This 3 dB difference makes the Polk RTi A3 a more sensitive speaker compared to Polk L200, 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.
L200 can handle a max power of 200 watts RMS from the amp the whereas RTi A3 has a max power handling value of 150 watts RMS, 50 watts less than the L200.
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
Both L200 and RTi A3 features dual binding post speaker terminals for bi-amping or bi-wiring.

Cabinet Type and Port Position
L200 has a rear firing port whereas RTi A3 has a back and front 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 L200's and Polk RTi A3's external dimensions. Polk L200 has external dimensions of 399.0 x 213.0 x 339.0mm ( 15-11/16 x 8-3/8 x 13-5/16inch) whereas Polk RTi A3 has external dimensions of 374.7 x 214.4 x 355.6mm ( 14.7 x 8.4 x 14.0inch) .
Polk L200 is 1.4mm narrower and 16.6mm less deeper than Polk RTi A3 but it is also 24.3mm taller.
Below you can see the front view size comparison of Polk L200 and Polk RTi A3 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 Polk L200 is approximately 722.1cm2 / 111.9inch2 and base area of the Polk RTi A3 is approximately 762.4cm2 / 118.2inch2. The L200 requires 5% less surface area than the RTi A3 which gives it a small advantage on placement in tight spaces.
