Quasi-bandpass subwoofer


Compact quasi-bandpass subwoofer

Optimally tuned vented enclosure delivers excellent transient response

Compact size and low weight for ease of use and installation

High excursion 15" neodymium LF drive unit

The EMS-115 is a compact, powerful subwoofer, intended to support the mid-sized fullrange loudspeakers from the EMS Series. The EMS-115 utilises a high excursion 15” (381mm) drive unit with a 4” (102mm) voice coil, and is fitted with a neodymium magnet assembly to keep weight to a minimum for touring applications. 

  • High power to size ratio
  • Premium 18mm multi-laminate birch plywood enclosure
  • Black textured paint finish
  • Optional weather protection or RAL custom colours
  • 35mm or M20 threaded pole mount adapter
  • Hex punched steel grille backed with acoustically transparent black foam

The enclosure is constructed from premium grade multi-laminate Birch plywood and is finished in impact resistant paint. Two flush handles, rubber feet and mating recesses, and a pole adapter (either 35mm or M20 threaded) are provided for flexibility when in use. For mobile applications, an optional set of tour grade castors is available.

The enclosure is finished in black textured paint as standard, however weather-protection options as well as custom RAL code colours are also possible. Two NL4 connections are recessed into the rear to allow for neat cabling, or even to stand the subwoofer on-end when used in installation environments where space is a premium.  Threaded fixings are provided on the rear for attachment of optional castors for mobile applications.

The EMS-115 can add low frequency power and extension to systems based around the EMS-61, EMS-81X or EMS-121X fullrange enclosures. The EMS-115 requires active high/low pass filters and a single amplifier channel capable of delivering 800-1000W RMS into an 8 ohm load. For optimum results, the EM Acoustics DQ10 or DQ20 Advanced System Amplifiers, or the AQ-10 or AD-9 power amplifier in conjunction with the DSC48 system controller (for loudspeaker filter slopes and protection) should be used.
