Beyma 15LEX1600Fe: 15" ferrite subwoofer with 1,600 W AES and a 4" voice coil
1,600 W AES thermal power handling on a 4" voice coil – within the LEX series the Beyma 15LEX1600Fe is the driver for subwoofers that have to absorb power in continuous use. The ferrite motor delivers 96 dB sensitivity into 8 Ω, and the working range extends from 40 to 1,500 Hz. At 13.9 kg it is a heavyweight that belongs in ground stacks, fixed installations and club subs, not in flown arrays.
Fs 38 Hz is the lowest resonance in this Beyma family, combined with Qts 0.33, Vas 106 l and an EBP of 97. The driver thus sits at the threshold where vented and sealed boxes both make sense. The stroke stays within the frame of a classic PA bass at 7.1 mm Xmax and 625 cm³ of displacement – the strength lies in the thermal headroom and in the control the BL of 19.2 Tm exerts over the 106 g moving mass. A Qms of 10.2 indicates a low-loss suspension.
Use and enclosure
As a guide value, the approximation gives a vented box of 66 l tuned to 43 Hz with an f3 of 47 Hz. For a 15" sub that is a moderate volume with decent extension; in a dual-15" cabinet you double the volume and get a sub with correspondingly higher power handling. Sealed, it works out to 30 l at fc 81 Hz – compact, but without equalisation too little extension for sub duty. Do the exact alignment including the port with the enclosure calculator on 42.audio.
The top end stops at 1,500 Hz; you sensibly place the crossover to the top well below that, in the typical sub/top region. With Le 1.2 mH the driver remains well controllable in the upper bass. A high-pass below fb and a limiter that respects the 7.1 mm Xmax are indispensable with 1,600 W of amplifier power – thermally the driver takes more than the mechanics tolerate below the tuning frequency.
What to look out for
- 13.9 kg ferrite motor: for fixed installation and ground stacks, build the cabinet accordingly.
- Mounting depth 183 mm – in dual-15" cabinets, allow depth for the port.
- 8 Ω, Re 5.2 Ω: amplifier up to 1,600 W into 8 Ω, always with a limiter.
- Xmax 7.1 mm: thermal headroom exceeds mechanical headroom – high-pass below fb.
- Fs 38 Hz, Qts 0.33: deep vented bass in a moderate volume.
Frequently asked questions
Is the 15LEX1600Fe worth it over the 15LEX1000Fe?
If you really need the 1,600 W AES in continuous use, yes. The 15LEX1600Fe has the 4" coil and the lower Fs of 38 Hz, but at 7.1 mm less Xmax than longer-throw drivers. For maximum deep-bass SPL with limited power a driver with more stroke is the better choice; for thermal robustness, this one.
Which enclosure suits the 15LEX1600Fe?
Vented with around 66 l tuned near 43 Hz is the guide value from the parameters and gives f3 at about 47 Hz. A sealed box of 30 l is only usable as a subwoofer with substantial equalisation.
How does it differ from the Beyma 15WRS400?
The 15WRS400 has almost the same Qts of 0.33 and an even lower Fs of 36 Hz, but a huge Vas of 236 l compared with 106 l. It therefore needs a much larger box and is more of a bass for big cabinets, whereas the 15LEX1600Fe is at home in more compact subs with high power handling.
Beyma 15LEX1600Fe: manufacturer, spellings and classification
Beyma and Acustica Beyma refer to the same manufacturer: Acústica Beyma S.L. of Moncada near Valencia, Spain. The 15LEX1600Fe is a 15-inch woofer with ferrite magnet from the LEX 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 15LEX1600Fe with all key data in the driver database and the enclosure calculator. More drivers from this manufacturer: Atlas Beyma.

Enclosure suggestion
The EBP of 97 is in the intermediate range — either works; sealed plays tighter, bass reflex deeper and louder. EBP = fs / Qes = 38 / 0.39
Sealed (Qtc 0.707)
- Enclosure volume Vb
- 29.5 l
- System resonance Fc
- 81 Hz
- Cut-off frequency F3
- 81 Hz
Bass reflex (QB3 after Small)
- Enclosure volume Vb
- 54.6 l
- Tuning frequency Fb
- 47 Hz
- Cut-off frequency F3
- 51 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.
