Tweeter; Sub-Frequency Port; Enclosure; Network & Power Amplifiers - M-Audio SP-5B Studiophile Series User Manual

2. Tweeter

By employing a specially developed 1" silk dome with magnetic shielding, the
tweeter can deliver distortion-free original sound and offer extremely natural
sound. It minimizes reaction time by using fabric silk for excellent delivery, and
also minimizes resonance by adapting a unique Internal Damping Technology.

3. Sub-Frequency Port

The hole in the rear panel is called a Sub-Frequency Port which discharges
extreme low frequencies under 30 Hz. The SP-5B is designed to take advantage
of this port to generate extreme low frequencies.

4. Enclosure

The enclosure has an important role just as the other components. The SP-5B's
enclosure is designed to endure impact from inside under extreme conditions. It
employs high-density special MDF and unique interior reinforcement to provide
more stable performance.
5. Network & Power Amplifiers
The Network & Power Amplifiers for the SP-5B are specially designed for its
woofer and tweeter. The Network properly distributes low, mid, and high
frequency to units in order to reduce loss of sound and distortion, thus achieving
a natural balance of sound.
In order to generate ultra crisp, powerful sound quality, there are two separate
power amplifiers inside the SP-5B to drive the Woofer and Tweeter drivers
separately as a high-end Bi-Amp structure. The power delivered to the woofer
driver at a rated distortion is 42W and 36W is delivered to the Tweeter.
