M&K speakers were also used for all of the industry demonstrations of AC-3 prior to the introduction of actual processors by individual manufacturers.

page 4 May 98 M&K Sales Training Outline Company Background & History http://www.mksound.com Kreisel’s earliest passion was for recording pipe organs and other live musical performances. These perfectionist recordings were of true audiophile quality, and many were cut as LPs, first for demonstrations at Jonas Miller's salon and later for sale because of their popularity and acclaim.

M&K Sales Training Outline The Satellite-Subwoofer System Concept page 5 May 98 http://www.mksound.com M&K's has the most (24+ years) experience with Satellite-Subwoofer systems M&K is the only speaker manufacturer that has produced only Satellite and Subwoofer systems since 1974. M&K makes Satellite-Subwoofer systems because we believe this is the optimum configuration for reproducing music and film sound.
PAGE 6
M&K Sales Training Outline Deep Bass Subwoofer Cabinets Designs page 6 May 98 http://www.mksound.com M&K uses only sealed-box cabinet designs for superior transient response and Deep Bass All M&K Subwoofers (and Satellites) are sealed-box designs, tightly packed with highly efficient sound absorbing material. This configuration delivers the best transient response, and is the only design capable of producing true Deep Bass.
PAGE 7
M&K Sales Training Outline Deep Bass Subwoofer Drivers & Amplifiers page 7 May 98 http://www.mksound.com M&K proprietary high-performance subwoofer drivers All M&K subwoofer drivers are designed by and manufactured exclusively for M&K. Our designers take full advantage of the fact that these drivers are used to reproduce only the lowest bass frequencies, thereby allowing the drivers to be optimized for the best low frequency transient response and lowest distortion.
PAGE 8
M&K Sales Training Outline Powered Deep Bass Subwoofer Amplifiers page 8 May 98 http://www.mksound.com Control of system "Q" to deliver tight, musical bass "Q" is a measure of quality that involves the speaker's transient performance, with a low "Q" being better. Subwoofers with passive radiators, vented boxes (bass reflex) or bandpass designs use air in a chamber or port as a high Q resonator, much as a bottle filled with water whistles at one frequency when you blow across its opening.
PAGE 9
M&K Sales Training Outline Push Pull Dual Driver Deep Bass Subwoofers page 9 May 98 http://www.mksound.com Push-pull dual driver configuration M&K’s innovative Push-Pull Dual Driver configuration delivers a major improvement in subwoofer detail and clarity by virtually eliminating even-order harmonic distortion, which produces a boomy and poorly defined bass sound. In these subwoofers, one driver is mounted conventionally on the cabinet’s front baffle. The second driver, however, is mounted inverted.
PAGE 10
M&K Sales Training Outline Push Pull Dual Driver Deep Bass Subwoofers page 10 May 98 http://www.mksound.com Ease of service M&K subwoofers have a 3 year warranty, which includes the subwoofer amplifier. Compare that to competitive products. All M&K amplifiers and crossovers utilized printed circuit boards for maximum reliability, QC testing, and easy of service. Unlike M&K, many speaker crossovers are simply glued to a mounting panel or the cabinet itself, and they cannot be easily removed or tested.

M&K Sales Training Outline Optimizing Subwoofer location in a room page 11 May 98 http://www.mksound.com Installing subwoofers Ultimately, the amount and quality of bass you get in a room are dependent on the room itself and the location of the subwoofer in that room. Low frequency bass sounds are affected most by the size of the room and the method of construction used to build it.
PAGE 12
M&K Sales Training Outline Optimizing Subwoofer location in a room page 12 May 98 http://www.mksound.com Special techniques for finding the best location for a subwoofer Here are two useful techniques for placing a subwoofer in a room. The first is unique in that it does not involve moving the subwoofer around the room: Place the subwoofer where your main listening position will be, connected to your system.
PAGE 13
M&K Sales Training Outline Using Multiple Subwoofers page 13 May 98 http://www.mksound.com Advantages of multiple subwoofers Whenever possible, we recommend using two (or more) subwoofers in any system. A second subwoofer significantly improves a system's total bass output, dynamic range, and headroom. The second unit doubles the amount of driver radiating area, which, depending on room placement, increases efficiency as much as 3 dB (the same as doubling the amplifier's power).
PAGE 14
M&K Sales Training Outline Powered Subwoofers page 14 May 98 http://www.mksound.com Servo and other types of feedback Many customers ask about negative feedback in powered subwoofers. M&K does not currently manufacture subwoofers using servo feedback, although the original Volkswoofer did have a servo circuit. Here is some discussion on the subject. Feedback uses a sensor mounted on the speaker that detects the movement of the cone.
PAGE 15
M&K Sales Training Outline Satellite Speakers page 15 May 98 http://www.mksound.com Advantages of Satellite Speakers Because M&K Satellites do not have to reproduce deep bass (thanks to the M&K powered subwoofer), those Satellites are optimized to reproduce midrange and highs without size compromises.
PAGE 16
M&K Sales Training Outline Satellite Speaker Cabinets & Treatments page 16 May 98 http://www.mksound.com Small cabinet and front baffle sizes mean sharper imaging and less coloration than large speakers Midrange and high frequencies sound best when the speakers producing them are mounted on the smallest possible baffle (as long as the backward sound radiated from the driver is contained and absorbed, as in an acoustically stuffed sealed box).
PAGE 17
M&K Sales Training Outline Satellite Speaker Crossovers page 17 May 98 http://www.mksound.com Phase-Focused Satellite crossovers M&K's Phase-Focused crossovers deliver razor-sharp stereo imaging by combining three important elements of crossover design: Time Domain Analysis, Frequency Domain Analysis, and what we call Point-In-Space Analysis (a three dimensional analysis of the speaker’s response in the room).
PAGE 18
M&K Sales Training Outline Satellite Speaker Drivers page 18 May 98 http://www.mksound.com Advanced low-distortion woofer and tweeter designs The drivers used in M&K's Satellite speakers have extremely low distortion thanks in great part to their development using a speaker driver measurement technique known as the "two-tone distortion test." This severe test measures the distortion produced when a driver is fed with a swept signal consisting of two closely-spaced tones.
PAGE 19
M&K Sales Training Outline Home Theater setup with M&K Speakers page 19 May 98 http://www.mksound.com Connecting a subwoofer to a surround sound receiver or processor The preferred connection from a surround sound amp or controller is from the subwoofer output jack. This may be called SUBWOOFER OUT, MONO, LOW PASS, CENTER WOOFER, etc. This connection usually insures that a full bass signal is fed to the subwoofer. Never use the CENTER CHANNEL OUTPUT jack.
PAGE 20
M&K Sales Training Outline Home Theater setup with M&K Speakers page 20 May 98 http://www.mksound.com Speaker placement When M&K Satellites are being used in a Home Theatre system, placement becomes extremely important, as you will be balancing five or more speakers (not counting the subwoofer) rather than two. The following guidelines are for a five-channel Pro-Logic or 5.1 channel Dolby Digital/DTS system.
PAGE 21
M&K Sales Training Outline Home Theater setup with M&K Speakers page 21 May 98 http://www.mksound.com Front channels (cont.) For example, with a 25" direct-view television, you would want the speakers closer together than you would with a 100" projector. One recommendation is to separate the speakers by 1.5 times the diagonal screen size; another is to place the left and right speakers to create a 45 degree angle with the main listening position.
PAGE 22
M&K Sales Training Outline Home Theater setup with M&K Speakers page 22 May 98 http://www.mksound.com Surround channels (cont.) If you mount the surrounds on the side wall behind the listening position, they can be aimed towards each other or angled towards the back wall or the side wall surface directly behind them. By reflecting sound behind the listening position, you may increase the sense of envelopment in the sound.

M&K Sales Training Outline Home Theater setup with M&K Speakers page 24 May 98 http://www.mksound.com B. If you are willing to experiment, another option is to place the subwoofer at the listening position and walk around the room. Stand in and near each corner. The location where you hear the tightest bass with the most impact is probably the best location in the room for the subwoofer. C. If multiple subwoofers are used, place them in the same location.
PAGE 25
M&K Sales Training Outline Home Theater setup with M&K Speakers page 25 May 98 http://www.mksound.com 7. B. Bass Management: If the processor/receiver has a setting to turn the Subwoofer off or on, make sure that it is set to SUBWOOFER YES or ON. C. Dialog Normalization: If your component has this function, turn it off to avoid any possible effect on sound quality. D. THX Dolby Digital units have an adjustable limiter for the subwoofer feed, called “Bass Peak Level Management”.
PAGE 26
M&K Sales Training Outline Home Theater setup with M&K Speakers page 26 May 98 http://www.mksound.com NOTE: If you using identical speakers anywhere in your system (e.g., S-150THX speakers for the left, center, and right channels), all of those channels should be set to the same level. If your meter measures a different level, it is probably a limitation of this type of meter measurement method and not an actual audible level difference.
