Beyma 12P1000Nd: 12" neodymium woofer with 4" voice coil, 900 W AES and 96 dB up to 2000 Hz
Beyma's P series stands for woofers with midrange capability, and the 12P1000Nd is its neodymium representative in 12" format. A 4" voice coil, 900 W AES, 96 dB sensitivity and an operating range of 50 to 2000 Hz make it the driver for two-way PA boxes in which a 12" cone delivers bass and lower mids up to the handover to the compression driver. At 5.4 kg it is light thanks to neodymium, and the 132 mm mounting depth keeps the cabinet shallow.
The motor is tight: BL 23.5 Tm on 100 g of moving mass, Qes 0.27, Qts 0.26 and a Qms of 7.9. Fs 47 Hz and Vas 49 l are in the usual range for a 12" driver, Xmax 8 mm on 550 cm² gives 440 cm³ of displacement. Le is 2 mH, Re 5.1 Ω.
Use and enclosure
With an EBP of 174 the 12P1000Nd is a bass-reflex driver. As a guide value the Thiele-Small parameters give a volume around 15 l tuned to 66 Hz with an f3 near 81 Hz, which points to a compact two-way box with subwoofer support. Sealed it would be 7.7 l with fc around 128 Hz, usable as a lower-midbass chamber in a larger system. As with all low-Qts drivers, it pays to also simulate larger volumes with lower tuning in the enclosure calculator at 42.audio.
The handover to the tweeter should sit well below 2000 Hz; Le of 2 mH causes a distinct impedance rise in the upper range that has to be compensated passively or bypassed actively. Matching compression drivers and horns from Beyma are available at 42.audio.
What to look out for
- 8 Ω nominal, Re 5.1 Ω: amplifier with 900 W into 8 Ω, do not forget the limiter.
- 5.4 kg thanks to neodymium: a light 12" driver for touring boxes.
- Mounting depth 132 mm: shallow cabinets are possible.
- Xmax 8 mm, Vd 440 cm³: set a high-pass filter below the tuning frequency.
- Le 2 mH: account for the impedance rise in the crossover design.
Frequently asked questions
Which box is the 12P1000Nd meant for?
Compact two-way boxes: bass reflex around 15 l at 66 Hz as a guide value, with a compression driver on a horn above. For deep bass you combine the system with a subwoofer.
How does it differ from the 18Sound 12NLW9410?
The 12NLW9410 has Fs 42 Hz and Vas 55 l at the same Qts 0.26, so it goes deeper in a larger volume. The 12P1000Nd with Fs 47 Hz and Vas 49 l is more geared towards the lower-mid and midrange up to 2000 Hz.
Which amplifier fits?
900 W AES into 8 Ω means an amplifier in that power class, paired with a high-pass below the tuning and a limiter. At 96 dB sensitivity you reach high levels before power becomes an issue.

Enclosure suggestion
The EBP of 174 suggests a bass-reflex enclosure. EBP = fs / Qes = 47 / 0.27
Sealed (Qtc 0.707)
- Enclosure volume Vb
- 7.7 l
- System resonance Fc
- 128 Hz
- Cut-off frequency F3
- 128 Hz
Bass reflex (QB3 after Small)recommended
- Enclosure volume Vb
- 11.5 l
- Tuning frequency Fb
- 74 Hz
- Cut-off frequency F3
- 89 Hz
Vb is the required net internal volume, Fb the tuning frequency of the reflex port and F3 the frequency at which the level has dropped by 3 dB. Calculated approximation after Small. A starting point for simulation, not a finished build plan.
