What size room are the Polk XT70 and Paradigm SE 3000F 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:

400 sq. ft / 36 m2.
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 XT70 and Paradigm SE 3000F 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 XT70 is a 2-way design whereas the SE 3000F is a 3-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.

XT70 features a 1" Terylene dome Tweeter and 2 x 6.5" Bi-laminate paper Woofer . On the other hand, the SE 3000F features a 1" Tweeter , a 5.5" Midrange and 2 x 5.5" Mineral-filled polypropylene Woofer .
Frequency Response
XT70 has a frequency range of 35-40k Hz whereas SE 3000F has a frequency range of 55-21k Hz. With a minimum frequency of 35Hz, the XT70 can go significantly deeper on the low side and provide stronger bass compared to the SE 3000F'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
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
XT70 and SE 3000F have the same Impedance of 8 ohms but where they differ is the sensitivity levels. XT70 sensitivity is rated at 86 dB and the SE 3000F's is at 91 dB. This 5 dB difference makes the Paradigm SE 3000F a more sensitive speaker compared to Polk XT70, 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.
XT70 can handle a max power of 200 watts RMS from the amp the whereas SE 3000F has a max power handling value of 100 watts RMS, 100 watts less than the XT70.
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
XT70 features Post type posts and SE 3000F 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 Polk XT70's and Paradigm SE 3000F's external dimensions. Polk XT70 has external dimensions of 1031.0 x 275.0 x 340.0mm ( 40-9/16 x 10-13/16 x 13-3/8inch) whereas Paradigm SE 3000F has external dimensions of 1007.0 x 228.0 x 278.0mm ( 39-5/8 x 8-15/16 x 10-15/16inch) .
Polk XT70 is clearly the larger of the two speakers. Its body is 47mm wider, 24mm taller and 62mm deeper than Paradigm SE 3000F.
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 XT70 is approximately 935.0cm2 / 144.9inch2 and base area of the Paradigm SE 3000F is approximately 633.8cm2 / 98.2inch2. The XT70 requires 48% more surface area than the SE 3000F which gives it a small disadvantage on placement in tight spaces.
