Beyma 15P1000Fe/V2: 15" ferrite woofer with BL 27.4 Tm for compact vented boxes

BL 27.4 Tm – this figure defines the Beyma 15P1000Fe/V2 from the P series. Such a strong ferrite motor on a 4" voice coil results, at Fs 45 Hz, in a Qts of only 0.3 and an EBP of 145: the driver is made for small vented boxes, in which it generates very high SPL with 98 dB sensitivity and 1,000 W AES. The working range from 45 to 2,000 Hz makes it the woofer for 2-way PA cabinets and the kick bass in multi-way systems, not a deep-bass specialist.

At 157 g moving mass the cone is comparatively heavy, which benefits power handling and stability at high levels; the strong motor compensates for that in efficiency. Xmax 8 mm over 0.0855 m² of cone area gives 684 cm³ of displacement – solid for bass in a full-range cabinet. Vas 80.7 l and Le 1.5 mH round off the profile. At 13.1 kg the ferrite driver is a candidate for fixed installation and cabinets that are not flown.

Use and enclosure

The vented guide value is 38 l tuned to 56 Hz with an f3 of 63 Hz – a very compact box by 15" standards. That is exactly the purpose: a 2-way cabinet with a 15" and a horn that takes little space, hits hard in the kick and upper bass and gets a subwoofer underneath for deep bass. The sealed alternative of 18 l with fc 106 Hz suits satellites or a bass section coupled to a sub via high-pass. Check with the enclosure calculator on 42.audio if you want to build larger and tune lower.

The upper limit of 2,000 Hz is respectable for a 15" driver; still, cross well below it so the beaming of the large cone does not collide with the horn's coverage. A 1.4" or 2" compression driver with a horn from the Beyma range is the typical complement. A high-pass below the tuning frequency protects the 8 mm Xmax.

What to look out for

  • BL 27.4 Tm, Qts 0.3: strong motor, wants a compact vented box.
  • Weight 13.1 kg – ferrite, better for fixed installation than for flown systems.
  • Mounting depth 170 mm: moderate for a 15" driver, fits slim tops.
  • 8 Ω, Re 5.2 Ω: amplifier around 1,000 W into 8 Ω, high-pass below fb.
  • Upper limit 2,000 Hz – usable as the woofer in 2-way cabinets with a horn.

Frequently asked questions

Is the 15P1000Fe/V2 suitable as a subwoofer?

Only to a limited extent. With Qts 0.3, EBP 145 and a vented guide value of 38 l with f3 around 63 Hz it is a kick and upper-bass driver. As a sub you would need a considerably larger box and lower tuning; for genuine deep-bass duties choose a driver with higher Qts and more stroke.

Which amplifier fits?

An amplifier with around 1,000 W into 8 Ω exploits the AES rating. With 98 dB sensitivity you reach high SPL with considerably less power, though; a high-pass below the tuning matters more than the last few watts.

How does it differ from the 18 Sound 15NTLW2500?

Both have Fs 45 Hz and Qts 0.3 but differ in Vas: 143 l for the 18 Sound versus 80.7 l for the Beyma. The 15P1000Fe/V2 has a stiffer suspension and gets by with a smaller box – ideal when the top has to stay compact.

Beyma 15P1000Fe/V2: manufacturer, spellings and classification

Beyma and Acustica Beyma refer to the same manufacturer: Acústica Beyma S.L. of Moncada near Valencia, Spain. The 15P1000Fe/V2 is a 15-inch woofer with ferrite magnet from the P series, available from 42.audio, Beyma dealer in Germany, with datasheet and full specifications in the driver database.

At 42.audio you get the BEYMA 15P1000Fe/V2 with all key data in the driver database and the enclosure calculator. More drivers from this manufacturer: Atlas Beyma.
