The PRV 12MB1500FT has an excellent linear response, well controlled down to 75 Hz, which makes it a great option for 2-way cabinet systems that require strong BL magnet force and midbass punch. A great new addition to the Forte Series, where more power handling and less distortion on mid low mid bass frequencies is the key.

Supporting the cone is a heavy duty spider M roll treated cloth surround, designed for high excursion applications to handle short bursts of excessive power without damage. A double silicon spider system ensures excellent control during large excursions of 1.50″ peak-to-peak excursion before damage. 

A very strong ferrite magnetic structure of 25 mm guarantees dynamism and precision and a unique 3,5” inside/outside voice coil design provides a very high-power handling of 1500 Watts RMS of musical power, thanks to its dual forced cooling system guarantees a very efficient voice coil ventilation for minimum power compression.

Note: 

• Nominal power handling is defined as the maximum RMS power that the speaker can handle in a 2-hour test with a pink noise with 6dB of crest factor and a bandpass filter with 12db/oct tuned in its usable frequency range.
• Continuous Program Power (RMS) is the maximum power that the speaker can handle considering a regular musical program using our recommended filters, this power can be used to define the optimum amplifier power to avoid a clean signal without clipping or saturation.
• Max Peak Power is the maximum power operation for the speaker, this power is allowed just for a few fractions of a second, usually found just on the peaks of the music. Keeping this power for a little longer timer will damage the speaker.
