<p>The compact Hi-Fi loudspeaker system comprises a resonance free enclosure (A) with three speaker drive units. The front baffle of the cabinet is fitted with a low-medium range unit (1) and a h.f unit (2) of the dome variety. The rear wall of the enclosure is fitted with a single bass speaker unit (3) radiating in the opposite direction to the other two units. A cross-ocer unit is connected to the speakers so that the front speakers receive only their designed frequency range. The rear facing speaker receives predominantly the low frequencies. Optionally, it can also be fed with part of the upper frequency spectrum.</p> |
