In this review, we will be comparing A500 and S400 MKII, two Bookshelf speakers by Buchardt The main difference between these two speakers is that the Buchardt A500 is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the Buchardt S400 MKII is a Passive speaker so has to be matched with an amplifier to get any sound from it.
Let's have a brief look at the main features
of Buchardt A500 and Buchardt S400 MKII first before getting into our more
detailed comparison.

Drivers
One of the fundamental differences between these two speakers is that A500 is a 3-way design whereas the S400 MKII is a 2-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.

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.
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 A500's and Buchardt S400 MKII's external dimensions. Buchardt A500 has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) whereas Buchardt S400 MKII has external dimensions of 365.0 x 180.0 x 280.0mm ( 14.4 x 7 x 11inch) .
In this case, we can see that Buchardt A500 and Buchardt S400 MKII have the exact same height, width and thickness.
