Description | | | | |
The black SUB 8004-AS Professional Series Active Subwoofer from RCF features a high-power, hypervented 18" woofer with 4" inside/outside voice coils designed to deliver a serious amount of low frequency. Powered by a 2500W digital amplifier module, the SUB 8004-AS can perform in the most demanding situations. The input board includes volume control, deep/punch switch, high-pass switch, phase switch, cardioid, and time delay.
The sub is stackable and lightweight for easy set up and tear down, thanks to the ergonomic handles. A pole receptacle on top and side allows the use of the sub in various configurations. The powder coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducer from dust.
RCF's Class-D power amplifier technology packs huge performance, operating with high efficiency into a lightweight solution. RCF amplifiers deliver an ultrafast attack, realistic transient response, and impressive audio performance. The amplifier features a solid machined aluminium structure, which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the amplifiers present SMPS power supply section to produce maximum output and minimum weight.
RCF developed advanced transducer technology including the application of high-tech materials such as neodymium, carbon fiber, pure titanium, kevlar, kapton, and mylar hybrids. RCF has been instrumental in technological inventions such as carbon fiber cone molding, double silicon spiders, inside/outside voice coil windings to edge wound voice coil manufacturing and pure titanium diaphragm forming.
RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, small dimensions compared to the competitors, self-powered design, internal delay control, cardioid configuration options and impressive size/weight to SPL output ratio.
The RCF cabinets are made of baltic birch plywood coated with a textured black finish. The subs are stackable and lightweight, for easy set up and tear down, thanks to the ergonomic handles. A pole receptacle on top and side allows the use of the box in various configurations. The powder coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducers from dust.

DBTechnologies' new subwoofers H Series offer remarkable specifications and user-friendliness. With 1500W (2000W Peak Power) and a high-performance 18' woofer with 8' coil, the Sub 18H is especially suited for small to mid-sized events, where high performance needs to be packaged into compact size. Thanks to their unique configuration, termed Hybrid Horn-Loading, the boxes can be tuned to the lowest frequencies to improve system efficiency and convey a deep, enveloping sound. Unlike conventional horn loaded systems, 15H and 18H subs ensure excellent efficiency even at close listening distance, which makes them suited for use even in small venues. |
Boasting an 18' woofer in a bass reflex housing, this bin delivers a low-ranging bass foundation. The specially designed active stereo x-over routes the right frequency spectrum to the mid/ high unit connected via the Satellite
Out. The active PR:O 18 SUB A model also ships with a 600W RMS power amp and a port for active satellites.
- Application: Subwoofer
- Output Power: 600 Watt
- Built-in stereo X-over
- Very punchy High-power Subwoofer for Bands and DJʼs

Data sheet
The LD Systems DDQ Sub 18 is a powerful active subwoofer with digital signal processing for demanding PA applications. It is precisely adapted for combination with the full-range speakers of the DDQ Series and is equally suitable for use with tops made by other manufacturers.
The compact bass-reflex design is loaded with an 18" FaitalPRO bass speaker that has a 4" voice coil and a neodymium magnet driven by two 700-watt Hypex Class D power amplifier modules with a highly efficient switching power supply with a total output of 1400 watts RMS. The DDQ Sub 18 attains a maximum sound-level pressure of 134 dB with a frequency response curve of 30 -120 Hz.
The Sharc DSP programmed especially for the DDQ subwoofers ensures distortion-free and reliable operation even at maximum volume levels with a 1ms look ahead limiter, frequency and phase correction, as well as all protection circuits, and has a large dynamic range of 127dB/113 dB (ADC/DAC). Seven DSP Presets permit selectable crossover frequencies between 80 and 120Hz. Eight additional presets make it possible to realize cardioid configurations of 2 or 3 subwoofers, whereby it is possible to attain rear attenuation of up to 20dB. In addition to XLR inputs and outputs, the DDQ Sub 18 has a separate mono output with a 100Hz high-pass filter. Additional features are LED function indicators and a ground lift switch; the volume and preset controls can be deactivated to prevent inadvertent adjustment.
The cabinet of the DDQ Sub 18 is made of 18mm thick multiplex with an extremely durable polyurethane finish. It is equipped with two M20 threaded flanges and ergonomic handles and is prepared for mounting of casters.
