Black metal speaker driver with silver cone and cloth surround, 200 mm diameter, 92 mm deep

Beyma

Beyma 8-in Low & Mid Frequency Transducer 4 Ohms

SKU CH-DYXD-WHC7A

An 8-inch low and mid-frequency transducer with a 4-ohm impedance, 94 dB sensitivity, and 250 W AES power handling for compact vented cabinets

  • Linear response with low distortion for accurate sound
  • 94 dB sensitivity delivers high output from modest power
  • 250 W AES power handling suits demanding applications
  • 80-8000 Hz range covers bass and midbass duties
  • 4 Ohm nominal impedance matches common amplifier designs

8-inch Low & Mid Frequency Driver

The Beyma transducer is an 8-inch low and mid frequency driver built for compact vented cabinets. Its pressed steel frame and ferrite magnet deliver a very linear extended response with low distortion. The treated double roll cloth surround supports reliable excursion in mobile sound reinforcement applications. This new component targets system integrators and DIY builders needing accurate bass and midbass output.

4 Ohm Nominal Impedance

The single specification that decides fit is the 4 ohm nominal impedance paired with 250 W AES power capacity and 94 dB sensitivity at 1 W/1 m. Frequency range spans 80 to 8000 Hz with a 75 Hz free-air resonance. The 38.1 mm voice coil and 9.6 N/A BL factor provide controlled motor strength for the recommended 20 litre enclosure volume. Xmax reaches 5.7 mm before mechanical limits engage.

Installers building compact vented enclosures

This driver suits installers building compact vented enclosures for mobile PA, stage monitors or fixed installations where 4 ohm loading matches the amplifier. Builders needing a different impedance, deeper low-frequency extension below 80 Hz, or a larger cone area for higher SPL should look at alternative models. The 92 mm mounting depth also requires sufficient baffle space behind the panel.

Questions about this item

What does the 94 dB sensitivity mean for real-world output?

At 1 W and 1 m the driver produces 94 dB, so typical amplifier power will determine the maximum SPL in a properly tuned enclosure.

How does the 4 Ohm nominal impedance affect amplifier pairing?

The 4 Ohm nominal impedance with a 5.1 Ohm DC resistance requires an amplifier stable into 4 Ohm loads for full power delivery.

What cabinet depth and volume are needed to mount this driver?

The driver is 92 mm deep and the manufacturer recommends a 20 L vented enclosure for bass and midbass applications.
