CF1/FF1 Magnetic Speakers
CF1/FF1MagneticSpeakers
Overview
TDT Magnetic Speakers offer high output and fidelity over a bandwidth from 1 – 50
kHz. These broadband speakers have more power at lower frequencies than our
electrostatic speakers, making them well suited for laboratory species with lower
frequency hearing. Their high output levels and broad bandwidth also make them
excellent for noise exposure studies.
These 4-Ohm magnetic speakers are available in either free-field or closed-field
models. The free-field model delivers signals of over 100 dB SPL with < 1%
distortion over its entire bandwidth (+/- 4 V, 10 cm). The closed-field model has
an internal parabolic cone designed to maximize output and minimize distortion. Its
tapered tip can be inserted directly to the subject’s ear or fitted with the provided
tubing and used with most standard ear tips.
The FF1 and CF1 magnetic speakers can be driven using either TDT’s SA1 or SA8
stereo amplifiers. The speaker input is connected via a BNC connector, which carries
both bias and signal voltages from the stereo amplifier. Both models feature a rugged
polymer enclosure with a stable base as well as a built-in, ¼”-20 threaded post for
positioning with laboratory mounting hardware.

Connections to the speakers are made through a BNC connector located on the back
of the FF1 and CF1 housing. If using the SA1 stereo amplifier, simply connect a
