B15P
Our subwoofer B15 is a real multi-talent. The bass-reflex system equipped with 1x 15? driver is especially suited as a passive bass extension for all our M-series speakers. Due to the speaker chassis specifically developed and optimised for this application we achieve outstanding bass response in spite of the compact design.
The fall-off in efficiency of the LF-driver to the higher frequencies causes a soft filtering of mid-high frequencies with the lowest possible phase-shift when combined with the optional passive crossover PWB15. Because of this the subwoofer can be connected in parallel with fullrange speakers without additional amplifiers or system controllers without problems.
The fullrange system is strongly supported in the low frequency range while staying almost unchanged in the midrange.
The highpass output of the passive crossover PWB15, tuned specifically to the M8, relieves the satellite speaker and lets the combination sound extremely homogenous.
Another advantage: caused by the speaker impedances of a passive combination of the B15 with one M12 or M15 fullrange speaker, the amplifier power is divided into two thirds to the subwoofer and one third to the top. This does not only relieve the fullrange system but also pro¬ motes balanced playback of music. Again and again and again.

Used TW AUDiO
Every development starts with an idea. And that’s where we start too. We get important input from communicating intensively and constantly with sound technicians, rental companies, installation specialists and architects. We use that input to help us develop products TW AUDiO users want on the basis of their needs, wishes and experiences.
The demands placed on loudspeakers today and in the future have been rising constantly over the past few years, with the emphasis on less weight, smaller dimensions, more performance, less complicated hand-ling, reliability, accessories for every conceivable situation, maximum flexibility and scalability, full integration into acoustic planing software, simple administration of complex systems via remote software, return on investment.
While of course not losing sight of the fact that sound is what it’s all about. Modern sound systems are required, just like audiophile studio monitors, primarily to broadcast and amplify as faithfully as possible voice, music and other sound events – sometimes louder, sometimes wider and further, and with the same quality of sound reaching every single audience seat.
We use exhaustive simulation and precise measuring technology in the development of our loudspeakers, carefully looking at and testing all the parameters and options that could come into play when they’re subsequently in use. Individual components and prototypes are thoroughly tested, and then beta tests are carried out on the pilot series systems in the field.
Every TW AUDiO product is the sum of all these crucial factors, and that’s how we ensure the quality, value and timelessness of our loudspeaker systems.

Efficiency Rating: Level of sound output measured at a prescribed distance with a standard input power. Efficiency rating standard is 1 watt (2.83V at 8 ohms) at 1 meter over a specified frequency range and is measured in decibels.
Equalization: Loosely, any type of relative frequency adjustment. Specifically, the process of changing the frequency balance of an electrical signal to alter the acoustical output.
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.
FM: Frequency Modulated.
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 a microphone 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.
HDCP: High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copyright material.
HDR: Hard-Drive Recorder. Device that uses a computer hard drive to store compressed digital audio and video signals.
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.
Integrated Amplifier: A combination preamp and amplifier.
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.
Line-Level (Low-Level): A level of electrical signals too low to make the average speaker move sufficiently. Amplifiers receive line-level signals and amplify them to speaker level.
lockout: The final words of a segment used to signify the production’s conclusion.
Low Pass: A filter that lets low frequencies go through but doesn’t let high frequencies go through. Same as high cut.
MHz: Megahertz, or 1 million Hz.
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.
MLP: Meridian Lossless Packing. Encoding format that is able to completely reconstruct the original signal at the receiving end. No information is lost or discarded, regardless of how trivial it might be. Used to encode six channels of high-resolution audio on DVD-A.
Mono: Monophonic sound. One channel.
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.
Nonlinear Editing: Digital audio systems that allow for clips to be extracted without affecting the master recording.
