8″ COMPETITION LOUDSPEAKER – These are the epitome of competition-quality midranges. Red aluminum baskets, cloth-edges, non-pressed paper cone, and high-strength Ferrite magnets make these the best loudspeakers available.
HIGH-GRADE CCAW AND FIBER GLASS VOICE COIL – 2” high-temperature CCAW + fiber glass voice coil can handle extreme heat and maintain its structural integrity meaning long life out of your speakers.
4. Pair of (2) Brand New Beyma Pro8mi 8″ Competition Series 400 Watt 4 Ohm Mid-bass/midrange Speakers
Beyma pro 8MI is a high power 8″ car midrange speaker from the beyma competition series. Handles 200 watts AES & 400 watts program power. Designed for medium frequencies reproduction. Features a large 2″ voice coil & a high 98db SPL. Delivers clear & detailed midrange of high quality. Available in 4 ohms only
Nominal diameter: 200 mm. / 8 in.. Nominal impedance: 4 ohms. Power handling / maximum: 200 W RMS / 400 W. Sensitivity: 98 dB 1w @ 1m. Frequency range: 150 – 7000 Hz. Voice coil diameter: 51.7 mm. / 2 in.. Bl factor: 7.6 N / A.
It’s important to emphasize that although this loudspeaker seems physically intended for woofer or subwoofer; this speaker is not designed to reproduce that frequency range. Meaning we could break it quite easily if we intend to give it such use.
On the contrary, if we use it to reproduce the frequencies for which it is designed, this speaker can generate very high levels with great high quality playback. But always as part of a system in which there also woofers and/or subwoofers to complement it and reproduce the lower frequencies where the midrange loudspeakers, with it’s special design, can’t.
The cutoff frequency recommended for these speakers not only have to take into account the frequency range, but also the impedance curve of each one of them. Based on these data the recommended cuts would be the following: Minimum lower cutoff frequency (High Pass): 200Hz. Maximum upper cutoff frequency (Low Pass): 4-5 kHz
