Woofer 1 x 6-inch 1 x 10-inch

Platinum 100 3G features a 1" MPD III Tweeter and 1 x 6" RDT III Woofer with a Crossover frequency at 2850 Hz. 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

Platinum 100 3G has a frequency range of 28-60k Hz​ whereas SourcePoint 10 has a frequency range of 42-30k Hz. With a minimum frequency of 28Hz, the Platinum 100 3G can go significantly deeper on the low side and provide stronger bass compared to the SourcePoint 10's min frequency of 42Hz.

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

Platinum 100 3G is a 4 ohms speaker compared to the SourcePoint 10 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 Platinum 100 3G can provide this impedance level.

These two speakers also have different sensitivity levels. Platinum 100 3G sensitivity is rated at 85dB and the SourcePoint 10's is rated at 91dB. This 6 dB difference makes the MoFi SourcePoint 10 a more sensitive speaker compared to Monitor Audio Platinum 100 3G, 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.

Platinum 100 3G can handle a max power of 200 watts RMS from the amp the whereas Platinum 100 3G has a max power handling value of 150 watts RMS , 50 watts less than the SourcePoint 10.

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

Platinum 100 3G features Binding 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.

Cabinet Type and Port Position

Both Platinum 100 3G and SourcePoint 10 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 Monitor Audio Platinum 100 3G's and MoFi SourcePoint 10's external dimensions. Monitor Audio Platinum 100 3G has external dimensions of 398 x 225 x 325.6 mm ( 15.6 x 8.8 x 12.8-inch) whereas MoFi SourcePoint 10 has external dimensions of 572 x 368 x 406mm ( 22.5 x 14.5 x 16 inch) .

MoFi SourcePoint 10 is clearly the larger of the two speakers. Its body is 143mm wider, 174mm taller and 97mm deeper than Monitor Audio Platinum 100 3G.

Below you can see the front view size comparison of Monitor Audio Platinum 100 3G 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 Monitor Audio Platinum 100 3G is approximately 731.3cm2 / 113.4inch2 and base area of the MoFi SourcePoint 10 is approximately 1552.0cm2 / 240.6inch2. The Platinum 100 3G requires 53% 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 Monitor Audio Platinum 100 3G weighs 15.20kg / 33.4lbs and the MoFi SourcePoint 10 weighs 21.00kg / 46.2lbs. This makes the SourcePoint 10 38% heavier than the Platinum 100 3G.
