Questions frequently asked
Is the Delta-12A suitable for a 12-inch PA speaker cabinet?
This model is designed for PA applications, with a power rating of 400 W at 8 ohms. Its sensitivity of 98.3 dB promotes a high acoustic level at equivalent amplification power.
What is the frequency response of this 12-inch speaker?
The specified response ranges from 54 Hz to 5 kHz. This range covers the bass and low-mid frequencies, with a usable rise towards a crossover region with a compression driver or tweeter.
Can it be installed in a bass-reflex enclosure?
A bass-reflex loading is among the intended applications for this speaker. The internal volume of the enclosure, the port tuning, and the crossover influence the final result.
What amplification is recommended for a 400 W, 8-ohm speaker?
The nominal impedance of 8 ohms allows for either a single or paired setup depending on the amplifier architecture. The rated power is 400 W.
Is the Delta-12A frame sturdy enough for PA use?
The frame is made of steel and the magnet is ferrite. The 64 mm voice coil contributes to power handling during sustained operation.
