Subwoofer, 18", Bandpass
The DVA S1518N is a bandpass subwoofer based on the DVA S10, but with 50 percent higher power amp output, an integrated DSP, and an RDNet link. A remarkably versatile subwoofer, it delivers tight and punchy bass response that supports and transitions smoothly to satellites? lower midrange frequencies.
The DVA S1518N is equipped with a next-generation, 18" woofer driven by a built-in 1500W digipro G2 digital power amp. Subwoofer arrays are easily flown using the optional SRK10 rigging hardware retrofit.
The S1518N will also serve you well in compact stacks paired with DVA T12, T8 and T4 units or DVX Series enclosures. Equipped with PFC switched-mode power supplies, they are largely impervious to line voltage fluctuations, which is a tremendous asset in a touring rig. Our network-enabled DVA subwoofers are designated by an ?N? in the product name. They feature a premium-quality DSP boasting excellent audio specs with variable crossover frequencies, precise limiter functions and adjustable delay settings for perfect time alignment.

dBTechnologies (1990) is a brand owned by AEB Industriale s.r.l., an italian Company founded in 1974 in Bologna (Italy), which is part of the Pro Audio industry leader RCF Group, providing a strong know-how in the Professional Audio market.
Its recent story begins in 2004 when Arturo Vicari, CEO of AEB Industriale s.r.l., acquired RCF and founded RCF Group, an international holding leader in design, production and marketing of products, systems and solutions for the public and private sound reinforcement.
Over the years, thanks to a policy of considerable investments in R&D, design and manufacturing, dBTechnologies has gained substantial recognition for some groundbreaking technological innovations, as well as their inherent standards of quality.
In particular, dBTechnologies has been one of the industry’s forerunner in active speaker & digital amplifier technologies, while giving a major emphasis to details and design. A constant research on new materials and technologies, together with the ability to create unique design solutions, are the key ingredients for an ever-increasing market share and success.
Today AEB Industriale's Headquarters are located in Crespellano (Bologna) with a total area of over 10,000 square meters housing the legal and production core, the sales and administrative offices, the warehouses, and the Research & Development department where all dBTechnologies' products are designed and developed.
In 2019, the brand is distributed in more than 160 countries worldwide, providing installation companies, rental companies, sound designers and musicians with audio equipment and combining top-quality sound performance with a distinguishable Made in Italy design.
Octave: The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 Hz.
Optical Digital Cable: Fiber optic cable that transfers digital audio signals as light pulses.
Outcue/Outq/Out-Point: These words all refer to the final few seconds of audio signifying the conclusion of the production.
Package: A completed and fully edited audio piece.
Passive: Not active. A passive crossover uses no external power and results in insertion loss. A passive speaker is one without internal amplification.
Phase: Time relationship between signals; it’s all relative.
Power Output: A measure, usually in watts, of how much energy is modulated by a component.
Preamplifier: A control and switching component that may include equalization functions. The preamp comes in the signal chain before the amplifiers.
Pre Outs: Connectors that provide a line-level output of the internal preamp or surround processor.
Pre Outs/Main Ins: Connectors on a receiver that provide an interruptible signal loop between the output of the internal preamp or surround processor portion of the receiver and the input of the amplifier portion of the receiver.
Pre/Pro: A combination preamp and surround processor.
Processors: Anything that processes an incoming signal in some way. Surround processors, for example, can decode a Dolby Digital signal to send to an amp so you can hear it.
Pulse Code Modulation: (PCM) a way to convert sound or analog information to binary information (0s and 1s) by taking samples of the sound and record the resulting number as binary information. Used on all CDs, DVD-Audio, and just about every other digital audio format. It can sometimes be found on DVD-Video.
Q-and-A: Question and answer session.
Receiver: Any component that receives, or tunes, broadcast signals, be it NTSC, HDTV, DBS, or AM/FM radio. Typically refers to the single component that includes a preamp, surround processor, multichannel amplifier, and AM/FM tuner.
Reverberation: The reflections of sound within a closed space.
RF: Radio Frequency. Television signals are modulated onto RF signals and are then demodulated by your television’s tuner. VCRs and DBS receivers often include channel 3 or 4 modulators, allowing the output signal to be tuned by the television on those channels. Also, laser discs used an RF signal for modulating Dolby Digital 5.1 soundtracks on some movies. This requires an RF demodulator (usually referred to as an AC3-RF demodulator) before or in the surround processor to decode the signal.
RMS: Root Mean Square or the square root of the arithmetic mean (average) of the square’s set of values. A reasonably accurate method of describing an amplifier`s power output.
SACD: Super Audio CD. Enhanced audio format with up to six channels of high-resolution audio encoded using DSD. Requires an SACD player. Multichannel also requires a controller with six-channel analog or proprietary digital inputs for full playback.
Sampling Frequency: How often a digital sample is taken of an analog wave. The more samples taken, the more accurate the recording will be. You need to sample at a minimum of twice the highest frequency you want to capture. For example, the 44.1-kilohertz sampling rate of a CD cannot record sounds higher than 22.05 kilohertz.
Scener: A radio report in which the announcer is recorded at the same time and place as the background sound of an event.
Sensitivity: A measurement (in dB) of the sound-pressure level over a specified frequency range created by a speaker driven by 1 watt (2.83V at 8 ohms) of power with a microphone placed 1 meter away.
Signal-to-Noise Ratio: A comparison of the signal level relative to the noise level. Larger numbers are better.
Simultaneous Interpretation: This system allows attendees to hear the meeting in their own language.
Sound Bite: A portion of audio of someone speaking.
Sound field: The total acoustical characteristics of a space, such as ambience number, timing, and relative level of reflections; ratio of direct to reflected sound RT-60 time etc.
Soundstage: The area between two speakers that appears to the listener to be occupied by sonic images. Like a real stage, a soundstage should have width, depth, and height.
Speaker: A component that converts electrical energy into acoustical energy.
SPL: Sound-Pressure Level. Measured in dB.
Subwoofer: A speaker designed to reproduce very low bass frequencies, usually those below about 80 Hz.
THX: Certification program for home theater equipment. Uses some proprietary features, but mostly assures a base quality level for a given room size. (See THX select or Ultra.) Is compatible with any and all soundtrack formats. Stands for either Tom Holman’s eXperiment, after the engineer who drafted the original standard, or is named after the company’s founder George Lucas first movie, THX 1138. Nobody agrees on which.
THX select: Certification program for speakers and receivers that assures a base level of quality and performance when played in a room that’s between 2,000 and 3,000 cubic feet.
User-Generated Content (UGC): Text, photos, video or audio supplied by the customers of a company.
Voicer: A radio report without background audio taken from a scene or otherwise.
Wrap: A radio report containing both the reporter and an actuality.
