In this review, we will be comparing Passif 50 and SourcePoint 10, two Passive Bookshelf speakers from PSB and MoFi. Let's have a brief look at the main features
of PSB Passif 50 and MoFi SourcePoint 10 first before getting into our more
detailed comparison.
What size room are the PSB Passif 50 and MoFi SourcePoint 10 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 PSB Passif 50 and MoFi SourcePoint 10 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Passif 50 features a 1" titanium dome with ferrofluid and neodymium magnet Dome Tweeter and 1 x 6.5" cast aluminum basket, paper cone Woofer with a Crossover frequency at 1800Hz. On the other hand, the SourcePoint 10 features a 1.25" wide roll soft dome Tweeter and 1 x 10" Paper-pulp Woofer with a Crossover frequency at 1600 Hz.
Frequency Response
Passif 50 has a frequency range of 50-20k Hz whereas SourcePoint 10 has a frequency range of 42-30k Hz. With a minimum frequency of 42Hz, the SourcePoint 10 can go significantly deeper on the low side and provide stronger bass compared to the Passif 50'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.

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
Passif 50 is a 6 ohms speaker compared to the SourcePoint 10 which has a nominal impedance of 8 ohms.
These two speakers also have different sensitivity levels. Passif 50 sensitivity is rated at 87 dB and the SourcePoint 10's is rated at 91dB. This 2 dB difference makes the MoFi SourcePoint 10 a more sensitive speaker compared to PSB Passif 50, 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.
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
Passif 50 features 5-Way post posts which make bi-amping or bi-wiring possible. SourcePoint 10 has a 5-Way post which doesn't 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 PSB Passif 50's and MoFi SourcePoint 10's external dimensions. PSB Passif 50 has external dimensions of 660 × 280 × 254mm ( 26 x 11 x 10-inch) whereas MoFi SourcePoint 10 has external dimensions of 572 x 368 x 406mm ( 22.5 x 14.5 x 16 inch) .
PSB Passif 50 is 88mm narrower and 168mm less deeper than MoFi SourcePoint 10 but it is also 88mm taller.
Below you can see the front view size comparison of PSB Passif 50 and MoFi SourcePoint 10 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 PSB Passif 50 is approximately 712.0cm2 / 110.4inch2 and base area of the MoFi SourcePoint 10 is approximately 1552.0cm2 / 240.6inch2. The Passif 50 requires 54% less surface area than the SourcePoint 10 which gives it a small advantage 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 PSB Passif 50 weighs 13.70kg / 30.1lbs and the MoFi SourcePoint 10 weighs 21.00kg / 46.2lbs. This makes the SourcePoint 10 53% heavier than the Passif 50.
Here is a comparison of how Passif 50 and SourcePoint 10's weights compare with the average, max and min weights in Passive Bookshelf class.
