What size room are the Buchardt S400 MKII and JBL L100 Classic 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* Buchardt S400 MKII JBL L100 Classic
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 Buchardt S400 MKII and JBL L100 Classic 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 S400 MKII is a 2-way design whereas the L100 Classic 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.

Driver Buchardt S400 MKII JBL L100 Classic
Driver Setup 2-way 3-way
Tweeter 0.74-inch 1-inch
Midrange - 1 x 5.25-inch
Woofer 1 x 6-inch 1 x 12-inch

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. On the other hand, the L100 Classic features a 1" Titanium Dome Tweeter , a 5.25" Midrange and 1 x 12" Pulp Woofer with a Crossover frequency at 450Hz and 3500Hz.

Frequency Response

S400 MKII has a frequency range of 33-40k HZ whereas L100 Classic has a frequency range of 40-40k 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 L100 Classic's min frequency of 40Hz.

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

S400 MKII and L100 Classic have the same Impedance of 4 ohms but where they differ is the sensitivity levels. S400 MKII sensitivity is rated at 88 dB and the L100 Classic's is at 90 dB. This 2 dB difference makes the JBL L100 Classic a more sensitive speaker compared to Buchardt S400 MKII, hence will play louder with the same amount of watts.

One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the S400 MKII and the S400 MKII can provide this impedance level.

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.

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 Buchardt S400 MKII's and JBL L100 Classic's external dimensions. Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) whereas JBL L100 Classic has external dimensions of 636.5 x 389.6 x 371.5mm ( 25.0 x 15.3 x 14.6inch) .

JBL L100 Classic is clearly the larger of the two speakers. Its body is 209.6mm wider, 271.5mm taller and 91.5mm 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 Buchardt S400 MKII is approximately 504.0cm2 / 78.1inch2 and base area of the JBL L100 Classic is approximately 1447.4cm2 / 224.3inch2. The S400 MKII requires 65% less surface area than the L100 Classic 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 Buchardt S400 MKII weighs 7.50kg / 16.5lbs and the JBL L100 Classic weighs 26.70kg / 58.7lbs. This makes the L100 Classic 256% heavier than the S400 MKII.

Here is a comparison of how S400 MKII and L100 Classic's weights compare with the average, max and min weights in Passive Bookshelf class.
