Verdict by Hobby HiFi 5/2007

"Loudspeaker "activation" by means of using digital crossover technology offers solutions that are unthinkable using passive crossovers. The effect is absolutely positive. The 1503 system is flexible, mechanically solid and stable under all loads. Sure, it's not cheap but it's certainly value for money."

After some research and many comparisons we also believe Ground Sound to be one of the best systems: it's absolutely solid, stable and easy to handle.

We supply all Ground Sound modules and Ground Sound solutions.

The Ground Sound system 1503 was published in Hobby HiFi, and can be evaluated in our show rooms.

Connection of the Ground Sound system is as follows:Ground Sound 1503

The input of the Ground Sound
(left) needs to be connected to the
pre out of the amplifier
.

The loudspeaker outputs
should be connected directly (possibly with fuses)
to the loudspeakers
.

For programming
a PC
has to be connected
to the programming input.

Therefore, a passive crossover and a main amp is not needed. Active amplification is - with regard to versatility and signal quality far superior to a passive solution with passive crossover.

Ground Sound: main amp with crossover and 600 Watt main amp per loudspeaker.

The Ground Sound kits contain: a digital crossover, two resp. three high performance main amps PA6CC (with 600 Watt each into 4 Ohm), the cabinet, the heat sink, the transformer the power supply PSU 12 SA and further accessories, like switches that are needed for set up.

The kit is available as 2 or 3 way version:

- the 3 way complete kit 1503 with all required components and 3 x 600 W
Price per speaker (as pictured above) - not available

- the 2 way complete kit 1502 with all required components and 2 x 600 W
Price per speaker (as pictured above) - not available

Ground Sound: main amp with 300 Watt per speaker and crossover

- the 3 way complete kit 603 with all required components and 3 x 300 W
Price per speaker (as pictured above) EUR 2173,00

- the 2 way complete kit Chassis 1502 with all required components and 2 x 300 W
Price per speaker (as pictured above) EUR 1992,00
