Bag End Introduces The IDS12-I Subwoofer System Built-In Features, Designed For Permanent Installation



By Gary Reber


The new IDS12-I subwoofer system from Bag End Loudspeakers is designed specifically to deliver high fidelity extended range low frequency sound from a compact enclosure at a reasonable cost. The IDS12-I features a built-in Dual Integrator, and provides perfectly flat response down to 18 Hertz. In addition, the subwoofer’s 12-inch INFRA core enables the IDS12-I to maintain tightly packed bass, aligned with the upper range signal to produce a seamless musical connection with the main loudspeakers. The subwoofer is self-contained, featuring a built-in 220-watt amplifier, and offers a Balanced Female XLR input connection.

The IDS12-I is ideal for background and foreground music system applications, including film and video presentations. Its reasonable cost and compact size make it a practical choice for venues that call for a cost-effective subwoofer that does not sacrifice sound reproduction quality. In addition, Bag End also offers optional fly-point mounting for the IDS12-I.

The IDS12-I is housed in a compact, sturdy 13-ply birch plywood enclosure measuring 15” high x 18” wide x 15” deep, and is fronted with a 16-gauge vinyl-coated perforated steel grille (an optional cloth
grille is also available). Enclosures are available in a wide range of colors or unfinished and ready for staining.
