Dayton Audio DAEX32EP-4 Thruster Exciter

Powerful Sound From Rigid Surfaces!

The Dayton Audio DAEX32EP-4 Thruster Exciter turns suitable surfaces into high-performance speaker diaphragms. The passive sound exciter combines 40 Watt RMS power handling with a 4 Ohm impedance, a robust 32 mm voice coil and a powerful neodymium motor. This makes the transducer ideal for custom surface speakers, DML systems, flat-panel speakers, furniture, glass panes, displays and demanding DIY audio projects.

Robust Drive Technology For High Power Handling

The proprietary, two-layer voice coil is mounted on a sturdy steel spider. This high-duty construction produces strong restoring force and supports reliable vibration transfer at higher power levels. With 40 Watt RMS power handling, the DAEX32EP-4 can excite large, thick and rigid materials that present greater mechanical resistance to smaller audio exciters.

The rare-earth neodymium motor generates a strong magnetic flux around the voice coil. This makes the surface transducer efficient and allows it to be paired with compact Class-D amplifiers designed for 4 Ohm loads. That enables space-saving audio solutions without needing a conventional speaker chassis or a visible diaphragm.

Quick Installation With 3M VHB Adhesive

For the most direct transfer of acoustic energy, the Dayton Audio exciter comes pre-applied with a high-performance 3M VHB adhesive. The adhesive pad is pressed onto the intended surface after removing the protective film. No additional screws or drilling are required for adhesive mounting.

Two male quick-connect tabs provide a fast electrical connection to the speaker wiring. The compact design simplifies hidden integration into furniture, signage, exhibition panels, enclosures, vehicles or multimedia installations.

Flexible Sound Design With DML Technology

On the DAEX32EP-4 the mounted surface itself serves as the sound diaphragm. This produces especially thin Distributed Mode Loudspeakers (DML) and invisible or discreetly integrated speaker solutions. The exciter can, for example, set glass panes, wood panels, composite materials or other suitable rigid surfaces into vibration.

Frequency response, sensitivity and achievable level are strongly influenced by the material, size, thickness, attachment and mounting position of the chosen surface. Thinner and smaller materials tend to deliver higher levels with a stronger mid- and high-frequency content. Larger and thicker surfaces can produce a fuller sound but often operate at lower levels and may require multiple exciters.

Versatile For Private And Commercial Audio Projects

The surface transducer is suitable for invisible home cinema and multiroom systems, signage, point-of-purchase displays, kiosks, multimedia exhibitions, distributed sound systems and automotive audio. In speaker DIY it also opens creative possibilities when conventional speaker enclosures are too large or visually undesirable.

When choosing an amplifier, pay attention to 4-Ohm stability and an output power rating appropriate to the RMS power handling. Final tuning should always be done with the actual surface and mounting position used.
