TW Audio VERA 20-B18 Sound Package Ex-demo

Ref. code: 1.01.398


Enchantingly powerful

Measuring just 60 cm (23.6") in width, the VERA20 houses two powerful 10" woofers despite being of a comparable size to many of the less impactive double 8" cabinets found in the market today. More than many similarly sized compact alternatives, the VERA20`s double 10" design packs a punch, delivering a throaty low-mid growl with up to 6 dB more output in the low-mid frequency range plus lower distortion.
Meanwhile the custom chassis boasts a purpose developed waveguide producing 12 degrees vertical dispersion and either 80 or 120 degrees horizontal dispersion, as required. This combines a 1.4" mid-high compression driver with a 3" diaphragm to produce sparkling top-end. When you choose VERA20, you can expect a smooth and precise mid-range response that lends itself to sharply defined speech intelligibility and exacting musical reproduction.
In addition, the low frequency crossover point delivers consistently uniform coverage, while the extraordinarily fast transient response contributes to a detailed and crisp performance in the high frequencies.
Crucially, the VERA20 offers you the capacity to form arrays of up to 24 elements, meaning it can be deployed in an extremely broad variety of applications, both inside concert halls and outdoors in arenas. Rigging is speedy, accurate and cost-efficient with the inclusion of TW AUDiO`s innovative EasyRig? hardware, with which an entire system can be set up and flown or dismantled by just one technician. That same hardware will also allow you to fly your VERA20 array with incredible precision, setting angles of less than one degree to swiftly achieve unsurpassed accuracy and far longer throws for improved coverage.
Having the same width as the VERA20 and equipped with the same rigging, VERA S32 subs can easily and unobtrusively be integrated into VERA20 arrays.

Depth Control Subwoofer

A milestone TW AUDiO development, the B18 is the result of countless customer requests for a subwoofer of this quality and flexibility. Combining tight control with a remarkably deep and distinctive rumble, the B18 features a symmetrical band pass design that delivers a consistent performance regardless whether vertical or horizontal, stacked vertically or side by side.
This includes the creation of directional sub arrays with partly reversed subwoofers. Facilitating the easy and inconspicuous wiring of directional bass clusters, the B18 even offers two speakON connectors on its front grille.

Used TW Audio

TW AUDIO "simply your sound" for professional applications.Product range comprises a series of special and excellent individual components, as well as complete public address systems and intelligent accessories. Always combined with the TW AUDiO system philosophy.

Active: Powered. An active crossover is electrically powered and divides the line-level signal prior to amplification. An active speaker includes an active crossover and built-in amplifier.

Actuality: Audio from an announcer speaking.

Amplifier: A component that increases the gain or level of an audio signal.

Balanced Input: A connection with three conductors: two identical signal conductors that are 180 degrees out of phase with each other, and one ground. This type of connection is very resistant to line noise.

Bandpass: A two-part filter that cuts both higher and lower frequencies around a center band. A bandpass enclosure cuts high frequencies by acoustic cancellation and low frequencies by natural physical limitations on bass response.

Bandwidth: In audio, the range of frequencies a device operates within. In video, the range of frequencies passed from the input to the output. Bandwidth can also refer to the transmission capacity of an electronic communications device or system the speed of data transfer,is very important when planning a meeting for the attendees to stay connected.

Bass: Low frequencies; those below approximately 200 Hz.

Bi-Wiring: A method of connecting an amplifier or receiver to a speaker in which separate wires are run between the amp and the woofer and the amp and the tweeter.

Boost: To increase, make louder or brighter; opposite of attenuate.

Bridging: Combining two channels of an amplifier to make one channel that more powerful. One channel amplifies the positive portion of an audio signal and the other channel amplifies the negative portion, which are then combined at the output.

CD: Compact Disc. Ubiquitous digital audio format. Uses 16-bit/44.1-kHz sampling rate PCM digital signal to encode roughly 74 or 80 minutes of two- channel, full-range audio onto a 5-inch disc.

CD-R: Recordable Compact Disc.

CD-RW: Rewritable Compact Disc.

Channel: In components and systems, a channel is a separate signal path. A four-channel amplifier has at least four separate inputs and four separate outputs.

Coloration: Any change in the character of sound (such as an overemphasis on certain tones) that reduces naturalness.

Crossover: A component that divides an audio signal into two or more ranges by frequency, sending, for example, low frequencies to one output and high frequencies to another. An active crossover is powered and divides the line-level audio signal prior to amplification. A passive crossover uses no external power supply and may be used either at line level or, more commonly, at speaker level to divide the signal after amplification and send the low frequencies to the woofer and the high frequencies to the tweeter.

Crossover Frequency: The frequency at which an audio signal is divided. 80 Hz is a typical subwoofer crossover point and is the recommended crossover point in theatrical and home THX systems. Frequencies below 80 Hz are sent to the subwoofer signals above 80 Hz are sent to the main speakers.

Cut: To reduce, lower; opposite of boost.

Decibel (dB): A logarithmic measurement unit that describes a sound`s relative loudness, though it can also be used to describe the relative difference between two power levels. A decibel is one tenth of a Bel. In sound, decibels generally measure a scale from 0 (the threshold of hearing) to 120-140 dB (the threshold of pain). A 3dB difference equates to a doubling of power. A 10dB difference is required to double the subjective volume. A 1dB difference over a broad frequency range is noticeable to most people, while a 0.2dB difference can affect the subjective impression of a sound.

Delay: The time difference between a sonic event and its perception at the listening position (sound traveling through space is delayed according to the distance it travels). People perceive spaciousness by the delay between the arrival of direct and reflected sound (larger spaces cause longer delays.

Diaphragm: The part of a dynamic loudspeaker attached to the voice coil that produces sound. It usually has the shape of a cone or dome.

Diffusion: In audio, the scattering of sound waves, reducing the sense of localization. In video, the scattering of light waves, reducing hot spotting, as in a diffusion screen.

Digital Audio Server: Essentially a hard drive, a digital audio server stores compressed audio files (like MP3 or WMA). Most include the processing to make the files, and all have the ability to play them back.

Direct-Stream Digital: A format for encoding high-resolution audio signals. It uses a 1-bit encoder with a sampling rate of 2,822,400 samples per second (verses 44,100 for CD). Used to encode six high-resolution channels on SACD.

Dispersion: The spread of sound over a wide area.

Distortion: Any undesired change in an audio signal between input and the output.

DNR: Dynamic Noise Reduction. A signal-processing circuit that attempts to reduce the level of high-frequency noise. Unlike Dolby NR, DNR doesn’t require preprocessing during recording.

Dolby B: A noise-reduction system that increases the level of high frequencies during recording and decreases them during playback.

Dolby C: An improvement on Dolby B that provides about twice as much noise reduction.

Dolby Digital: An encoding system that digitally compresses up to 5.1 discrete channels of audio (left front, center, right front, left surround, right surround, and LFE) into a single bitstream, which can be recorded onto a DVD, HDTV broadcast, or other form of digital media. When RF-modulated, it was included on some laser discs, which requires an RF-demodulator before the signal can be decoded. Five channels are full-range; the .1 channel is a band-limited LFE track. A Dolby Digital processor (found in most new receivers, preamps, and some DVD players) can decode this signal back into the 5.1 separate channels. Most films since 1992`s Batman Returns have been recorded in a 5.1 digital format, though a number of films before that had 6-channel analog tracks that have been remastered into 5.1.

Dolby EX: An enhancement to Dolby Digital that adds a surround back channel to 5.1 soundtracks. The sixth channel is matrixed from the left and right surround channels. Often referred to as 6.1. Sometimes referred to as 7.1 if the system uses two surround back speakers, even though both speakers reproduce the same signal. Software is backwards-compatible with 5.1 systems, but requires an EX or 6.1 processor to obtain additional benefit.

Dolby Pro Logic: An enhancement of the Dolby Surround decoding process. Pro Logic decoders derive left, center, right, and a mono surround channel from two-channel Dolby Surround encoded material via matrix techniques.

Dolby Pro Logic II: An enhanced version of Pro Logic. Adds improved decoding for two-channel, non-encoded soundtracks and music.

Driver: A speaker without an enclosure; also refers to the active element of a speaker system that creates compressions and rarefactions in the air.

DSP: Digital Signal Processing. Manipulating an audio signal digitally to create various possible effects at the output. Often refers to artificially generated surround effects derived from and applied to two-channel sources.

DTS: Digital Theater Systems. A digital sound recording format, originally developed for theatrical film soundtracks, starting with Jurassic Park. Records 5.1 discrete channels of audio onto a handful of laser discs, CDs, and DVDs. Requires a player with DTS output connected to a DTS processor.

DTS ES: An enhanced version of the 5.1 DTS system. Like Dolby’s Surround EX, a sixth channel is added. In some cases (DTS ES Discrete), the sixth channel is discrete. Software is backwards-compatible with 5.1 systems, but requires an ES or 6.1 processor to obtain additional benefit. Neo: 6 is a subset of DTS ES that creates 6.1 from material with fewer original channels.

Dynamic Range: The difference between the lowest and the highest levels; in audio, it’s often expressed in decibels. In video, it’s listed as the contrast ratio.
