Beyma 18P1000FeV2/S: 18" woofer with 1200 W AES, BL 26.8 Tm and bandwidth up to 2000 Hz

The Beyma 18P1000FeV2/S is an 18" woofer from the P series with ferrite motor, 4" voice coil and 1200 W AES power handling. Unlike pure subwoofer drivers it is specified broadband from 30 to 2000 Hz, which qualifies it for two-way full-range cabinets with an 18" and a horn as well as for vented subs. Sensitivity is 98 dB at 8 Ω, weight 13.5 kg.

BL 26.8 Tm at Qts 0.32 and Qes 0.33 stand for a strong motor with firm control over the 221 g cone assembly. fs 33 Hz and Vas 230 l fit a medium-sized vented box, Le 1.75 mH is moderate for a 4" coil and makes the 2000 Hz upper limit plausible. Xmax 8 mm and Vd 1,000 cm³ show that the driver relies on efficiency and motor force rather than extreme excursion.

Use and enclosure

EBP 100 marks the border between the two enclosure types. Vented is the sensible choice: the guideline is 131 l tuned to 39 Hz with an f3 around 42 Hz – a manageable volume for bass tops and subs. Sealed, 59 l with fc at 73 Hz is the starting point, only useful with a subwoofer below or equalisation. Mounting depth is 212 mm.

As a full-range bass in a two-way box, cross it well below the 2000 Hz upper limit to a horn with compression driver; matching Beyma horns and waveguides are listed in that category at 42.audio. For comparison: the 18 Sound 18LW1400 with fs 33 Hz, Qts 0.32 and Vas 210 l is almost identical in enclosure design, the 18 Sound 18NTLW5000 with Vas 176 l gets by with less volume. At 1200 W a high-pass belongs below tuning so the 8 mm Xmax is respected; check the alignment in the enclosure calculator.

What to look out for

  • 8 Ω, Re 5.2 Ω: a standard load for PA amplifiers.
  • 13.5 kg ferrite driver, mounting depth 212 mm.
  • Xmax 8 mm, Vd 1,000 cm³: plan a high-pass below the 39 Hz tuning at 1200 W.
  • Upper limit 2000 Hz: usable as a two-way bass with a horn.
  • Qts 0.32, EBP 100: vented guideline 131 l.

Frequently asked questions

Can I use the 18P1000FeV2/S as a full-range bass in a two-way box?

Yes, that is what the bandwidth up to 2000 Hz is for. In the 131 l vented guideline you cross well below that limit to a horn with compression driver. Which crossover frequency fits depends on the horn; Beyma horns and waveguides are available at 42.audio.

18P1000FeV2/S or 18 Sound 18LW1400?

Both have fs 33 Hz and Qts 0.32, the 18LW1400 Vas 210 l, the Beyma Vas 230 l – the enclosures come out almost the same. The 18P1000FeV2/S brings 1200 W AES, BL 26.8 Tm and bandwidth up to 2000 Hz. Both are in the shop, the parameter comparison is in the driver database.

How deep does the 18P1000FeV2/S really go?

In the 131 l guideline enclosure the f3 is around 42 Hz. The 30 Hz lower limit is only reached with a larger volume or equalisation, and the 8 mm Xmax is used up quickly at low frequencies. For genuine sub-bass a driver with more excursion is the better choice.

Beyma 18P1000FeV2/S: manufacturer, spellings and classification

Beyma and Acustica Beyma refer to the same manufacturer: Acústica Beyma S.L. of Moncada near Valencia, Spain. The 18P1000FeV2/S is a 18-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 18P1000FeV2/S with all key data in the driver database and the enclosure calculator. More drivers from this manufacturer: Atlas Beyma.

Enclosure suggestion

The EBP of 100 is in the intermediate range — either works; sealed plays tighter, bass reflex deeper and louder. EBP = fs / Qes = 33 / 0.33
