What size room are the MoFi SourcePoint 8 and Buchardt S400 MKII 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:

Listening Environment* MoFi SourcePoint 8 Buchardt S400 MKII
Near-field Poor Poor
Small Room Average Average
Mid-size Room Good Good
Large Room Average Average
Very Large Room Poor Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 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 MoFi SourcePoint 8 and Buchardt S400 MKII compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Driver Setup 2-way 2-way
Tweeter 1.25-inch 0.74-inch
Midrange - -
Woofer 1 x 8-inch 1 x 6-inch

SourcePoint 8 features a 1.25" wide roll soft dome Tweeter and 1 x 8" Paper-pulp Woofer with a Crossover frequency at 1600 Hz. On the other hand, the S400 MKII features a 0.74" fine weave soft fabric textile aluminum waveguide Tweeter and 1 x 6" paper Woofer with a Crossover frequency at 1800Hz.

Frequency Response

SourcePoint 8 has a frequency range of 47-30k Hz whereas S400 MKII has a frequency range of 33-40k HZ. With a minimum frequency of 33Hz, the S400 MKII can go significantly deeper on the low side and provide stronger bass compared to the SourcePoint 8's min frequency of 47Hz.

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

SourcePoint 8 is a 8 ohms speaker compared to the S400 MKII which has a nominal impedance of 4 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 S400 MKII can provide this impedance level.

These two speakers also have different sensitivity levels. SourcePoint 8 sensitivity is rated at 87dB and the S400 MKII's is rated at 88 dB. This 1 dB difference makes the Buchardt S400 MKII a more sensitive speaker compared to MoFi SourcePoint 8, 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.

SourcePoint 8 can handle a max power of 200 watts RMS from the amp the whereas SourcePoint 8 has a max power handling value of 150 watts RMS , 50 watts less than the S400 MKII.

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.

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 MoFi SourcePoint 8's and Buchardt S400 MKII's external dimensions. MoFi SourcePoint 8 has external dimensions of 456 x 290 x 320mm ( 18 x 11.4 x 12.6 inch) whereas Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) .

MoFi SourcePoint 8 is clearly the larger of the two speakers. Its body is 110mm wider, 91mm taller and 40mm deeper than Buchardt S400 MKII.

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 MoFi SourcePoint 8 is approximately 928.0cm2 / 143.8inch2 and base area of the Buchardt S400 MKII is approximately 504.0cm2 / 78.1inch2. The SourcePoint 8 requires 84% more surface area than the S400 MKII 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 MoFi SourcePoint 8 weighs 12.70kg / 27.9lbs and the Buchardt S400 MKII weighs 7.50kg / 16.5lbs. This makes the SourcePoint 8 69% heavier than the S400 MKII.
