Beyma 10WR300: 10" woofer with 2" voice coil, 300 W AES and 95 dB for bass-reflex cabinets

Beyma's WR series stands for 10" woofers that deliver bass and midrange from a single cone in two-way PA boxes and monitors. The 10WR300 uses a 2" voice coil, handles 300 W AES and reaches 95 dB sensitivity across 55 to 5000 Hz. Its 5000 Hz upper limit makes it a partner for a 1" compression driver without needing a midrange in between.

The Thiele-Small parameters are classic: Fs 52 Hz, Qts 0.35, Vas 42 l and a BL of 17.8 Tm on 65 g of moving mass. Xmax of 6.5 mm and a displacement volume of 572 cm³ are appropriate for a 10" driver in this power class. At 3.5 kg and 160 mm mounting depth it is neither lightweight nor heavyweight, a solid ferrite format for fixed installation.

Use and enclosure

An EBP of 186 places the 10WR300 firmly in a bass-reflex cabinet. The guide value is a volume around 31 l tuned to 56 Hz with an f3 near 59 Hz. Sealed it would be about 14 l with a cut-off around 105 Hz, interesting only as a midrange chamber or with subwoofer support. Both values come from the approximation formulas and should be checked in the enclosure calculator at 42.audio with port and excursion curves.

In a 10" two-way box the 10WR300 runs up to the crossover to the tweeter; with an upper limit of 5000 Hz the handover sits comfortably below that, and Le of 0.95 mH remains manageable. Matching 1" compression drivers and horns from Beyma are in the corresponding category at 42.audio.

What to look out for

  • 8 Ω, Re 6.2 Ω: amplifier power around 300 W into 8 Ω is sufficient, limiter recommended.
  • Mounting depth 160 mm: relatively deep for a 10" driver, plan cabinet depth accordingly.
  • Xmax 6.5 mm with tuning at 56 Hz: set a high-pass filter below fb.
  • 2" voice coil, 3.5 kg: solid thermal reserves in ferrite format.

Frequently asked questions

Which box suits the 10WR300?

Bass reflex around 31 l tuned to 56 Hz gives an f3 near 59 Hz as a guide value. That is a common volume for a compact 10" two-way box or a monitor wedge.

Which amplifier suits the 10WR300?

A power amplifier with around 300 W into 8 Ω covers the 300 W AES rating. More important than power reserves is a high-pass filter below the tuning frequency so the 6.5 mm Xmax is not exceeded.

How does it compare with the 18Sound 10NW750?

The 10NW750 has almost identical parameters at Fs 52 Hz, Qts 0.36 and Vas 38 l, but it is a driver from the database. The 10WR300 is available in the 42.audio shop and can be simulated directly in the enclosure calculator.

At 42.audio you get the BEYMA 10WR300 with all key data in the driver database and the enclosure calculator. More drivers from this manufacturer: Atlas Beyma.
