In this review, we will be comparing Premier 200B and Q350, two Passive Bookshelf speakers from Paradigm and KEF. Let's have a brief look at the main features
of Paradigm 200B and KEF Q350 first before getting into our more
detailed comparison.
What size room are the Paradigm 200B and KEF Q350 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 Paradigm 200B and KEF Q350 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Premier 200B features a 1" Hard-Dome Tweeter and 1 x 6.5" Carbon-Infused Polypropylene Woofer . On the other hand, the Q350 features a 1" vented aluminum Dome Tweeter and 1 x 6.5" Aluminum Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Premier 200B has a frequency range of 55-25k Hz whereas Q350 has a frequency range of 63-28k Hz. With a minimum frequency of 55Hz, the Premier 200B can go significantly deeper on the low side and provide stronger bass compared to the Q350's min frequency of 63Hz.
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
Premier 200B and Q350 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Premier 200B sensitivity is rated at 90 dB and the Q350's is at 87 dB. This 3 dB difference makes the Paradigm 200B a more sensitive speaker compared to KEF Q350, 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.
Premier 200B can handle a max power of 130 watts RMS from the amp the whereas Q350 has a max power handling value of 120 watts RMS, 10 watts less than the Premier 200B.
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
Premier 200B features Post type posts and Q350 has a Post type posts. None of these speakers feature bi-amping/bi-wiring.
KEF Q350's Post terminals
Cabinet Type and Port Position
Both Premier 200B and Q350 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
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 Paradigm 200B's and KEF Q350's external dimensions. Paradigm 200B has external dimensions of 342.0 x 199.0 x 328.0mm ( 13-7/16 x 7-13/16 x 12-7/8inch) whereas KEF Q350 has external dimensions of 358.0 x 210.0 x 306.0mm ( 14.0 x 8.2 x 12.0inch) .
Paradigm 200B is 11mm narrower and 16mm shorter than KEF Q350 but it is also 22mm deeper.
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 Paradigm 200B is approximately 652.7cm2 / 101.2inch2 and base area of the KEF Q350 is approximately 642.6cm2 / 99.6inch2. The Premier 200B requires 2% more surface area than the Q350 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 Paradigm 200B weighs 8.18kg / 18lbs and the KEF Q350 weighs 7.60kg / 16.7lbs. This makes the Premier 200B 8% heavier than the Q350.
Here is a comparison of how Premier 200B and Q350's weights compare with the average, max and min weights in Passive Bookshelf class.
