Subwoofer Velodyne CHT-12

Vented slotted port on the front - the constant sign Velodyne. CHT-12 is included in the original series of Classic Home Theatre. Cool design! Hopefully looks speaker with carbon fiber reinforced (for rigidity at high amplitudes) paper cone, voice coil and a four powerful magnet - almost half of the mass of CHT-12! Inside panel saturated linear and high-amplitude terminals, bypassing the LPF (position Direct), with two discrete HPF cut all outputs, auto and phase inverter. Without friction and backlash made potentiometers regulators. Measurements of the upper cutoff frequency LPF coincides with the passport - 120 Hz. Lower limit - 28 Hz. Frequency response at high solution LPF has a high stability. Average SOI by the peak at 80 Hz is 2.2% (94 dB).

At CHT-12 has a notable quality expensive woofer - reliable speaker. Always saved hard reinforcing rod upper bass, causing the characteristic spasm in the diaphragm. And with deep bass all very right - judging by the "reaction" of floor and chairs under you. In comparison with the CHT-8 subwoofer naturally powerful, but his large head is not so easy to withstand sharp edge of the pulse (drums, shots). No happiness in life... It helps limit bandwidth LPF and use satellites with good low-frequency potential. CHT-12 - powerful bass and subwoofer, whose talents can be effectively implemented in a spacious home theater of the highest category. With careful tuning sub great help on the classics and especially rock. By the way, in a series of CHT is, besides subwoofers agreed with them a satellite speakers and center speaker.
