Carecteristiques-key speaker of the diameter is 30cm (12pouces) high elongation (xmax 12mm, 44mm xmech), cellulose membrane Kevlar line (very hard), magnetic motor oversize (about 4.5 kg), molded salad has 12 branches provides ultra rigid anti vibration.
- What HP is intended primarily for application or the descent into the grave below is paramount, with its high elongation and its resonant frequency can be 22Hz up by volume load and adapt the agreement HP has multiple applications.
- Personally I use configuration in a low-reflex subwoofer volume (110litres) agree very low (about 21hz) is driven by an amplifier module 5230 Keig shall issue 200W has a nominal impedance This caison your descent down the infrastructure is ideal for the home cinema.
it can be used for the sound system in dual configuration hp in a volume of 160litres agreement 30Hz.
PS: the suspension being a little flexible, the filtering infrastructure is important for high power use has not be overlooked.

SOUNDS

As indicated above this is prestressed for HP infra.

OVERALL OPINION

I refer this choice without this problem HP is good quality massive and robust construction (10kg) rigid diaphragm, high elongation.
the least are: the flexibility of the suspension which can cause problems of fragility if we push the HP max power below 25Hz.
