dB Technologies SUB 18H Product Description

Sub 18H is the perfect choice whenever a powerful lower extension is required: equipped with a 1500W (2000W Peak Power) power amplifier and a high-performance 18" woofer with a 4" coil, the sub features a unique termed hybrid horn-loaded configuration and can be tuned to the lowest frequencies in order to improve the system's efficiency and convey a deep, enveloping sound.

dBTechnologies' new subwoofers H Series offer remarkable specifications and user-friendliness. Unlike conventional horn loaded systems, 18H subs ensure excellent efficiency even at close listening distance, which makes them suited for use even in small venues.

The sub offers stereo inputs with selectable link or crossover outputs, a crossover frequency switch at 90 or 120 Hz, a phase inversion switch and built-in delay up to 4.5 ms (adjustable in 0.5 ms steps).

The delay helps you to improve the correct coupling with the whole line-up of dB Technologies full-range speakers, and to make advanced subwoofer configurations without the help of any external processor (Cardioid or End-Fire or Straight Line).

As a matter of fact, the built-in features - variable crossover frequency, phase and delay - let the new Sub H Series be compatible with any other speaker of our lines.

The subs also feature a mini USB Type-B port to update system firmware.

The latest-generation digital amplifier Digipro G3 ensures excellent performance and low energy consumption thanks to its highly efficient, yet very lightweight system. The auto-range digital power supply allows it to operate both on 110V~ and on 220V~.

The new 28/56 Bit DSP with 24 Bit/48KHz A/D conv. provides sound performance above all expectations and perfect system control even under the most extreme operating conditions, thanks to its advanced limiting functions.

The PVC faced birch plywood speaker box is extra resistant also thanks to polypropylene edges that protect it from scratching or impacts during transport. This unique Hybrid Enclosure Technology offers outstanding strength and durability, making your speaker truly road-ready, with their exclusives Aluminum heavy-duty handles.

The M20 threaded mount on the top end of the box permits any type of full-range speaker to be installed using a standard pole with M20 thread.

DS2-S mini pole is also available as an option to adapt any dB Technologies speaker to 18H sub.

Spent months looking for one sub that would complement my QSC K12.2'S Looked at Yamaha....FBT....and even the Qsc 181.....simply put....28HZ...nothing goes this low.This sub packs a serious punch and literally throws it's bass directly on the dance floor where you want it. Best purchase I've made this year. Amazing value and superb build quality.
