About this product


Designed for optimal ease-of-use, the Adamson SpekTrix is a three-way active cabinet that employs two Adamson 8.5 Kevlar, Neodymium drivers, and one B&C DE 900 compression driver mounted on a patented Adamson wave shaping sound chamber. The two 8.5 drivers are each distinct the first is a woofer while the second is a mid range driver.
The sound chamber has a defined coverage pattern of 5-degrees V by 120-degrees H, and is similar to the inner body of a Yaxis drive module with a few modifications. This chamber gives the SpekTrix a slightly curved iso-phase wave front comparable to that of a Yaxis system.
The SpekTrix features Adamson's new Revolving Disk rigging all hardware is recessed, attached and hidden inside the box when arrayed, making the cabinets perfect for industrial applications where you want a system to look discreet. One person can easily accomplish setup of an entire array. The SpekTrix rigging frame is equipped with a single threaded moving pick point, so the center of balance and tilt angle can be precisely adjusted with little effort.
The sleek, trapezoidal SpekTrix cabinet weighs only 62 lbs, and is constructed from rugged 5/8 Baltic birch with a dual component black speckle coat finish.
All SpekTrix cabinets are supplied with lightweight, rugged aluminum dolly boards (four cabinets per dolly), with flight cases available upon request.
The modest styling and compact size of the Adamson SpekTrix makes it perfect for use in small theaters, clubs and houses of worship.

SpekTrix W

The SpekTrix WAVE (Wide Angle Vertical Enclosure) utilizes the same components as the SpekTrix and can be amplified and processed in parallel with the 5° model. The increased vertical coverage pattern of 15° SpekTrix W makes it the optimal downfill solution at the bottom of an array and perfect for use in a wide vertical array designs.
The AIR rigging system is simple and effective, consisting of a laser-cut revolving disk allowing for 3 splay positions. The enclosure is also available with EIR installation rigging, a plate system that reduces cost and weight.

Since 1983 Adamson Systems Engineering has been recognized as an industry leading manufacturer of products for the professional touring and installation market.
Today, our products are developed by a team of engineers renowned for creating the most technologically advanced loudspeakers and electronics in the world.

Equalizer: A component designed to alter the frequency balance of an audio signal. Equalizers may be graphic, parametric, or a combination of both. Fade: A gradual increase in audio, i.e. a fade-up, or a gradual decrease in audio, i.e. a fade-down.Feedback: The transmission of current or voltage from the output of a device back to the input, where it interacts with the input signal to modify operation of the device. Feedback is positive when it's in phase with the input and negative when it's out of phase. Frequency: The number of cycles (vibrations) per second. In audio, audible frequencies commonly range from 20 to 20,000 cycles per second (Hz). In video, frequency is used to define the image resolution. Low-frequency video images depict large objects or images. Higher frequencies depict smaller objects (finer details). Frequency Response: A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz, 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency level. Full-Range: A speaker designed to reproduce the full range (20 Hz to 20 kHz) of audio frequencies.Gain: Increase in level or amplitude.Gooseneck: This refers to amicrophone with a flexible neck that is most frequently attached to a podium or lectern. It is designed to allow the speaker to raise or lower the microphone to a suitable height.Graphic Equalizer: A type of equalizer with sliding controls that creates a pattern representing a graph of the frequency-response changes. Raising sliders boosts the affected frequencies; lowering sliders cuts (attenuates) the affected frequencies.High Pass: A filter that passes high frequencies, and attenuates low frequencies. Same as low cut.Hz: Hertz or cycles per second. Something that repeats a cycle once each second moves at a rate of 1 Hz.Incue/Inq/In-Point: These words all refer to the initial few seconds of audio signifying the beginning of the production.Impedance: A measure of the impediment to the flow of alternating current, measured in ohms at a given frequency. Larger numbers mean higher resistance to current flow.KHz: Kilohertz or one thousand Hz.Lavaliere: A small microphone that attaches to clothing, allowing the speaker to have a hands-free presentation.Line Array: A group of speakers that have been arrayed or “built up” in the vertical or horizontal plane, which allow for a highly consistent sound field. A Line Array is perfect for medium to large audiences.Midbass: The middle of the bass part of the frequency range, from approximately 50 to 100 Hz (upper bass would be from 100 to 200 Hz). Also used as a term for loudspeaker drivers designed to reproduce both bass and midrange frequencies. Midrange: The middle of the audio frequency range. Also used as a term for loudspeaker drivers designed to reproduce this range. Mixer: This is the unit in which audio signals are directed from. A mixer provides for both mic and line input combinations while allowing you to control one or more outputs.MP3: MPEG-1 Audio Layer-3. Compression scheme used to transfer audio files via the Internet and store in portable players and digital audio servers. Natural Sound (NATS): The nonverbal audio that occurs in a non-studio setting. NATS can be used to help characterize the setting.Noise: An unwanted portion of a signal such as hiss, hum, whine, static, or buzzing.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.surround processor portion of the receiver and the input of the amplifier portion of the receiver.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.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. 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 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. 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.
