Beyma 10MI100: 10" midrange with 98 dB, Qts 0.21 and only 0.25 mH inductance

The Beyma 10MI100 belongs to the MI series, which is designed for midrange with high precision. Two figures stand out immediately: the very low inductance of 0.25 mH and the tight Qts of 0.21. The first keeps the impedance almost flat across the 70 to 4,000 Hz working range so the upper mids do not roll off; the second stands for a heavily damped motor with clean transient behaviour.

The ferrite motor brings the driver to 7.1 kg and, with 12.8 Tm of BL acting on a moving mass of only 52 g, reaches 98 dB sensitivity. The 3" voice coil is rated for 350 W AES, resonance sits at 50 Hz, Vas at 54 l and Xmax at 4.5 mm. This is a driver optimised for sound quality in the midrange rather than for maximum power intake.

Use and enclosure

The 10MI100 fits 3-way systems for sound reinforcement and demanding DIY projects where the midrange should stay as uncoloured as possible. The EBP of 100 sits right at the boundary where closed and vented alignments are both feasible. For midrange duty, a closed compartment with a guideline of 5.2 l and an in-box resonance of 168 Hz is recommended; place the lower crossover well above the 70 Hz limit, sensibly above the box resonance.

If you want to run the driver as a mid-kick into the upper bass, the vented guideline is 9.2 l tuned to 86 Hz with an f3 of 116 Hz. Towards the top the 10MI100 is usable to 4,000 Hz; thanks to the low inductance it can also be crossed passively without elaborate impedance compensation. The 42.audio enclosure calculator handles the exact design.

What to look out for

  • Le only 0.25 mH: flat impedance curve, simple passive crossover.
  • 98 dB at 8 Ω, Re 6.4 Ω: high efficiency, little amplifier power required.
  • 350 W AES on a 3" voice coil: high-pass below the crossover is mandatory.
  • Ferrite magnet, 7.1 kg, mounting depth 153 mm.
  • Xmax 4.5 mm: pure midrange, no bass.

Frequently asked questions

10MI100 or 10MC700Nd for the midrange?

The 10MC700Nd offers 700 W AES and a light neodymium motor, while the 10MI100 offers 98 dB sensitivity and, at 0.25 mH, considerably lower inductance. If you need maximum power and low weight, take the MC; if you cross passively and value detail, take the MI.

Which amplifier fits?

With 98 dB sensitivity an amplifier delivering far less than the 350 W AES rating is sufficient. What matters more is that the amplifier works cleanly into 8 Ω and that the signal is high-pass filtered before reaching the driver.

Closed or vented?

For midrange, closed with 5.2 l as a guideline. Only if the driver is to run into the upper bass does the vented guideline of 9.2 l at 86 Hz become interesting, and then with respect for the 4.5 mm Xmax.
