Four Hybrid Tower Loudspeaker Four Hybrid Tower Loudspeaker Classic Series The NHT Classic Four is a formidable tower style loudspeaker. While the Classic Four looks like a conventional tower speaker, it’s really a three-way bookshelf speaker (the Classic Three) sitting on it’s own, integrated subwoofer stand. This design provides the detailed imaging, delicious midrange and natural sound-stag- ing of a fine bookshelf speaker with the bass and dynamics you’d expect from a first class tower speaker. Provided you use a reasonably powerful, high-quality receiver or pre/power-amplifier setup, the Four can fill a medium to large room with rich, full-range sound with ease. The Classic Four is perfectly at home in a high-quality home theater or in a reference 2-channel music playback system. Acoustic Suspension Hybrid: The Classic Four is an acoustic suspension design where it really counts - the critical midrange frequencies. In this section of the speaker, we use the air (natures most perfect spring) that is trapped inside the cabinet to control and “damp” the mid-woofer cone motion - like shocks on a car. This ensures the Classic Four will deliver smooth, natural midrange with untra- low distortion along with high power handling ability - an NHT hallmark. This sealed upper section blends perfectly with the built-in yet acoustically isolated, side-mounted 10” subwoofer that will provide usable in-room bass response to a remarkable 24Hz. This hybrid design allow the speaker to to deliver accurate midrange sonics you’d expect from a high end monitor speaker with the bass and dynamics that a larger floor standing speaker can provide. In addition, the subwoofer section may be bi-amplified for even more spectacular results. The Classic Four offer all this performance and technology in a price range typical of high-end bookshelf speakers Location, location, location: The Classic Four is a 4-way design (unusual as most tower speakers in this price range are 3-way designs). It uses a custom designed 10” aluminum cone subwoofer which is mounted on the lower side of the cabi- net near the floor, on a wide baffle - an acoustic environment well suited for low frequencies. The mid and high-frequency drivers are located proper acoustical environment as well - located on the narrow front baffle like a fine bookshelf speaker on a stand away from the walls. The low and high frequency portions of the speaker can be (bi)amplified separately for maximum performance. The Cabinet that is Art: The Four is made with CNC milled and laminated MDF (medium density fiberboard) of varying thicknesses. The front baffle is 30mm think full length. All other speaker panels are either 25 or 18mm. The Four has extensive internal bracing for rigidity which helps reduce unwanted resonances. Along with the internal braces, the Four’s cabinet actually has separate, acousti- cally isolated sub-enclosures for the mid/high frequency drivers and subwoofer sections. The the top front of the Four’s cabinet has variable radiuses flanking the midrange-tweeter module which help to randomize the upper frequency dif- fraction effects insuring great on and off-axis performance. The cabinet’s curved top, gentle edge radiuses and hand-rubbed, high-gloss piano-black finish lend a sense of timelessness to its visual aspect. Classic Four’s are sold and packaged individually as left or right side speakers. Also included are 2-piece BMC formed stabilizer wings with threaded inserts for included carpet spikes. Rubber pads are included for hard flooring. Adding a Subwoofer: The Classic Four is a full range speaker making a subwoofer completely optional. Adding a NHT Classic series subwoofer to a pair of Classic Fours will however allow the Fours to have additional application flexibility and allow the use of a less powerful receiver or amplifier. For example, Fours can be configured by your receiver or processor to operate as solo, full-range speaker for 2-channel music playback and then configured as large main speakers in the home theater mode - allowing separate subwoofer(s) to improve system dynamics and lowering total system distortion. If you are considering a subwoofer, we recommend one or two Classic B-12d’s as the perfect match followed by one or two Classic B-10d. Mixing and Matching: Building a home theater system? All NHT speakers are designed and voiced with the same design goals so you have the freedom to use any of our Classic Series center channel speakers. That said, the spot on recom- mend would be the Classic ThreeC center channel speaker followed closely by the Classic TwoC. Rear speakers? The perfect match would be stand or wall mounted Classic Three’s for surround and back channels but many people may opt for the Classic Absolute Zero’s in Black or White because of their compact size (or a combination of both).

  • Lynn Olson: a Tiny History of High Fidelity
    A Tiny History of High Fidelity, Part 1 A Rainy Night in Portland, 1936. Thanks to the restoration movement, much of downtown Portland still looks like this. Where do I come from? Where am I going? Who am I? These ancient questions are with us still. With only the slightest of changes, they can be recast into a form that provides a guidepost to the music lover, the audiophile, the hobbyist, and the artisan-engineer. Where does the art of sound reproduction come from? Where is it going? What do I seek from this art? Radio! 1900-1930 In the first years of Electrical Amplification, engineers had their hands full just trying to master the complex and non-intuitive mathematics of vacuum tube amplifiers and oscillators. It is worth keeping in mind that vacuum tubes were electronics in the first half of the Twentieth Century; before Lee DeForest modified Edison's light-bulb, the only form of "amplification" were relays that could repeat and rebuild telegraph signals. Radio relied on tuned circuits, massive brute-force spark-gap transmitters, large long-wave antennas, and crystal-diode rectification that directly powered the headphones. The faint signal that wiggled the headset diaphragm was a infinitesimal fraction of the megawatts that poured in all directions from the transmitter. Records, of course, were purely mechanical and acoustic, and wouldn't work at all if it weren't for horn-gain in recording and playback. What we now think of as electronic engineering back then was electrical engineering, focussed on keeping AC power transmission systems in phase and specialized techniques for pushing a telephone-audio signal down hundreds of miles of wire without benefit of amplification.

  • Three Bookshelf Loudspeaker
    Three Bookshelf Loudspeaker Classic Series The NHT Classic Three is the best bookshelf we’ve ever built and we’ve built quite a few over the last 22 years. The Three offers great bass response (close to 40Hz in room), plus wide-open, natural sounding mids and highs. While it’s a really good speaker for home theater, the Three is simply remarkable for music playback. Stereophile Magazine’s Robert J. Reina said “...the Classic Three is a superb value, par- ticularly for those listening rooms in which size and cosmetics are important but whose owners are reluctant to give up performance in bass definition and extension and in high-level dynamics.” Soundstage’s Sid Voola said “...in some ways, I would be hard-pressed to discern the Classic Three’s performance from that of a similarly priced small floorstander. Add in the outstanding imaging and soundstaging capabilities and the Classic Three becomes a very compelling value, clearly matching or exceeding the performance of other bookshelf de- signs. The overall neutrality and rich midrange reproduction enhance this value further and lead me to conclude that the NHT magic has been preserved -- and then some -- in the Classic Three.” The Perfect Vision’s (AVguide.com) Chris Martens said: “As I see it, whether listeners are spending $800 or $80,000 on a new pair of loudspeakers, they want the same thing— namely, to get as close as possible to the heart and soul of the music. No other afford- able bookshelf speaker I’ve heard does a better job of that than NHT’s Classic Threes”.

  • Sigma DSP for Active Speaker Systems ‐ Application Note Brewster Lamacchia 19‐Aug‐16 Momentum Data Systems
    Sigma DSP for active speaker systems ‐ application note Brewster LaMacchia 19‐Aug‐16 Momentum Data Systems http://www.mds.com Introduction The availability of low cost, efficient, high performance class D amplifier devices in the past few years has enabled the use of in‐speaker electronics for better performance in not just subwoofers but also in primary channels of consumer oriented audio components. The availability of A/D and D/A devices with enough dynamic range for high performance home audio has also been a key component in an active (powered) speaker design that uses DSP. While powered PA speakers for “Pro” audio have been available for a number of years, those systems typically lacked sophisticated signal processing and had limited performance parameters. Passive crossovers can be replaced with DSP based filters that allow optimal matching of woofer and tweeters (2‐ way systems) or more complex multi‐band drivers. With increased DSP processing not only can filters be implemented, but extra equalization to flatten the system response (or tune it for a specific sound characteristic) can be performed. That same DSP device can also be used to implement features that protect the drivers from damage due to thermal (overheating) effects of high power levels, as well as prevent hard clipping of the amplifier and/or excessive driver excursion, which have very audible side effects (increased distortion and heating for the former, and popping noise and/or mechanical failure for the latter). MDS has developed hardware platforms for in speaker electronics based on Analog Device’s Sigma DSP. The Sigma DSP integrates a number of useful peripherals and has a very simple and low cost power supply design.

First of all, I am there is one, I’d rather put those dollars into the music, too much of a cheapskate, and the really good systems i.e. the LPs, the tapes, the CDs, and now the downloads ordinarily cost out to dollar totals that are in the same and computer memory banks for tune storage. I have the audiophile voice frequently quipped that the music is more important than the gear and that I can always tell the difference between Bruce Springsteen and Barbra Streisand. However, I am not too arrogant to admit that sometimes two different speaker designs will sound enough alike for me to confuse them if I am not listening closely. This is particularly true if they have been level matched at perhaps 3 kHz and here I do not mean equalized over a broad band. The other main reason I don’t change speaker systems often is that the good ones are big and heavy and I am too lazy and weak to deal with such dif- ficulties if I can think of some sneaky way to get a better result.

  • Bookshelf Speaker Design Proposal
    BOOKSHELF SPEAKER DESIGN PROPOSAL Charles Young FA 4740 spring 2009 These speakers will be used primarily to monitor CDs and music generated by music composing programs to accompany musical instrument practice. They will be located in a spare bedroom used as a music practice room. Space for speakers is limited in the room and thus the speakers will be small and may be mounted on a wall. Proposed design size is 8 inches thick with a baffle of 10 by 12 inches, thus fitting my bookshelves, with a volume of .55 cubic ft or 15 liters. Anticipated loudness or power handling capability is small, less than 30 watts RMS amplifier capacity. It is expected that the driver design shall consist of a 4 to 6 inch woofer, a tweeter and a crossover. Possible enhancements to the frequency response should include enhanced bass response with a ported enclosure and separate attenuation of mid-range and high frequency response, to accommodate personal taste. Half-wave resonances in this size box are 500, 600 and 750 Hz based on c=1000 ft/sec. Proposed frequency response should have 3 to 5 dB ripple over the range 60 to 12,000 Hz, with a fall-back narrower range of 200 to 5000 Hz. Some smooth variation may be included for personal listening taste. It is doubtful that the sound pressure level will exceed 90 dB at 1 meter. Some low frequency enhancement is expected since the speakers will be mounted near or close to the wall, Subjective qualities should include 1) clarity of individual musical instruments and 1 clear high frequencies for reproduction of cymbals and high partials on stringed instruments and 2) clear low frequencies for reproduction of string basses and bass drum sounds.

Source: Reviewer purchase. Reviewer: David A. Rich In the early '50s a Hi-Fi enthusiast would put loudspeakers together by purchasing raw drivers from, say, Jensen, and would then put them in a big universal enclosure. The wonderful power of eBay (your junk is my treasure) has allowed me to get a copy of a 1954 Allied catalog, which shows this to be the real world of the time. In 1954, Ed Villchur changed all that when he introduced the acoustic suspension bookshelf speaker. The AR 3 was introduced just in time for stereo to come out. It had the first dome midrange and tweeter, instead of the horns being used by others. By the '60s, Acoustic Research was the largest quality speaker manufacturer in the country. In the late '60s, Roy Allison redesigned the line, introducing the modern soft dome. About the same time, the company was sold out to a conglomerate. Although the change in management marked the beginning of a downhill slide, the company still managed to bring out the landmark AR-9 tower unit in the mid '70s.

  • 100 Years 1915 − 2015
    CELEBRATING THE 100 YEAR ANNIVERSARY DANISH LOUDSPEAKERS 100 years 1915 − 2015 THE HISTORY OF THE DANISH LOUDSPEAKER INVENTION AND INDUSTRY FOREWORD Hearing is often considered as one of the most important of the traditional five human senses that allows us to communicate, understand, and navigate the world. The invention of the loudspeaker by the Dane Peter Laurits Jensen and Edwin S. Pridham in 1915 was groundbreaking. This enabled humans to communicate and experience sound from a distance, and further sparked the development of the 20th century’s most important technology products such as radios, telephones, and public address systems. 100 years later, the loudspeaker is still a ubiquitous element of sound reproduction systems and used in almost all sound technology products. Denmark was an early adapter of this new technology with the start-up of many companies as well as the introduction of university programs to support the technological development and constant flow of talented people. The present book covers important inventions, contributions, and amusing anecdotes from the 100 years of loudspeaker history, and not least, the flourishing of the Danish loudspeaker industry. Understanding the history is essential in order to prepare for the future, but it also helps us to form a strong identity. It is a fact that the Danish sound sector has been, and still is, very healthy and has a strong identity and excellent reputation worldwide. In a way, the anniversary of the loudspeaker is also the anniversary for everyone who works hard every day to keep-on transforming the sector and maintaining competitiveness. This is of course not an easy task.
