If a very powerful subwoofer - in a cabinet that is not too big - is required, we must remember that this subwoofer has to move lots of air as well. The SPH-380 TC is quite capable of doing that with a peak linear displacement volume of 960 cm3 (diaphragm surface area x voice coil overhang).
The driver features a twin voice coil with 2 x 4 Ohm, a power handling of 500 Watt RMS and was tuned for use with a small cabinet.
The picture below, left shows how the subwoofer performs in a bass reflex and in a closed cabinet version. The closed cabinet version shows a clearly more accurate bass - but without going that low. The maximum sound pressure level at lower frequencies, however, is considerably higher when using the bass reflex version (in our example the sub is optimally tuned for bass reflex).
The low bass properties of the DT300 are adjustable. We recommend, however, to use the neutral factory setting first. We believe it's the best setting for low bass and high volume.
The SPH-380/BR kit contains: - 1 x Monacor SPH-380 TC bass driver - 1 x Detonation DT-300 amplifier module - 1 x mat N25 napped foam - 8 x Allen wood screws 4x25 - building instruction
