Manufacturers Want to Quit China for Vietnam. They’re Finding It Impossible.
Soon thereafter, though, Mahul started producing his own woofers and tweeters under the Focal name, and these became wildly popular with a host of other high-end loudspeaker-makers. Tears were definitely shed when, in the early 90s, Jacques Mahul entered the automotive-speaker market and no longer had the capacity to keep supplying drivers to other audiophile manufacturers without compromising quality.
In , Mahul began phasing out the JMLab name and started branding his loudspeakers for home use as Focal. Complicated, right? Focal has long used Kevlar, a strong and heat-resistant synthetic fiber developed in the s, in its drivers for automotive applications.
The characteristic yellow color serves an important branding function, apart from any sonic advantages. Neither the Kevlar cones nor tweeters have ever been used in a Focal home loudspeaker—until now.
Each speaker weighs The enclosure is built with MDF, which Focal maintains provides the density and stiffness that best controls cabinet resonances and vibration. The front, rear, and top surfaces have a black high-gloss finish with the base a matte graphite black. Walnut side panels complete the luxurious appearance of the Spectrals. The top-most driver in this three-way design—the crossover frequencies are Hz and 2. Each speaker is provided with a grille to cover the midrange cone and a second, larger one that protects—or hides, depending upon your point of view—the pair of bass drivers.
For both, black cloth is stretched across a precisely molded plastic frame that conforms to recesses in the front baffle and is held firmly in place by substantial metal pins and rivets. In my 15' by 15' room—a hallway off one of the side walls ameliorates any standing-wave problems, with ceiling height ranging from 11' to 13'—the Spectral 40 th loudspeakers ended up pretty close to where my reference Magico S3 Mk2s live, as well as most other speakers here for review, ported or sealed-box.
They performed well when roughly 8' apart center-to-center, about 2' from the front wall, and 10' from the listening position.
They were canted in towards the sweet spot. Associated components for this evaluation included Pass XA The Spectrals acquitted themselves honorably as my day-in and day-out loudspeakers, in place of my usual Magico S3 Mk2s—though not for their first week. It took about hours of playing music for the sound to flesh out, more than that to reach what I felt was full potential. Once the Focals had reached their peak, bass was articulate and sufficiently extended for most music. The Spectrals transmitted all the electricity and sense of occasion of these classics.

With the revolutionary JBL Image Control Waveguide and refined transducers, JBL P MkII offers stunning detail, precise imaging, a wide sweet spot and impressive dynamic range that enhances the critical listening capabilities of any modern workspace. Why MkII? Since their release, word has spread on the quality and value found in the original JBL 3 Series, resulting in wide adoption from hobbyists to high-end professionals working in music, film, post, and broadcast production worldwide. With such an obvious hit, you might ask, "Why update now? When the opportunity presented itself, we decided to make those final improvements to the transducers, add a frequently-requested feature, and apply the latest manufacturing learnings.
Jordan Druber. Focal, who is celebrating 40 years of business this year , still hand makes cabinets for their extremely high-end Hi-Fi speakers in France rather than outsourcing them.

Michigan State University engineers have put together a flexible, paper-thin transducer — a device which can turn physical motion into electrical energy and vice-versa. The material could be used to create a whole new range of electronics powered from motion, as well as ultra-thin microphones and loudspeakers.

We partnered with expert Yorkshire weavers - Marton Mills for a speaker wrap that's as British to the eye as Yoyo's sound is to the ear. When we first thought about wrapping our speakers in British fabric we were occupied with thoughts of how to wrap it as tightly as possible to the casework and worrying about getting it as acoustically transparent as possible. We basically got to spend 48 hours in a LIVE episode and loved every second of it. The way the thread is transferred is using a creel. This rotating machine applies the correct spacing and tension to the threads for the desired outcome.

Audiophile Bs. Perform perfectly. Vocals sounded very slightly rough—first the main choral group, then the solo tenor. While the Loth-X was of modest disposition, I believe audiophiles will be amazed at its potential when fed from competent upstream components.
Effective date : Year of fee payment : 4. A dual diaphragm speaker comprising first and second diaphragms operating in accordance with the piezoelectric effect, the diaphragms being arranged to be driven in opposite phase with respect to one another so as to cancel out non-linearities.

Other sub-brands were 'John Bowers' for the Active One loudspeaker and preamp and 'Rock Solid' for a lifestyle speaker range. In the company opened a dedicated, purpose-built research centre titled 'SRE' or 'Steyning Research Establishment' in Steyning , about 10 miles from Worthing. The buildings were fit for audio-related work since they were previously used by SME , the English tonearm designer who felt the downturn in tonearm sales due to the introduction of the new digital media CD. SRE housed a prototype shop and listening rooms, ranging from semi-anechoic to typical small living rooms.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. A speaker makes sound because an electromagnet the embroidered coil is mounted to a membrane the fabric with a permanent magnet close by. When an audio signal is connected to either end of the electromagnet coil a fluctuating magnetic field forms around the coil, repelling and attracting the membrane from the permanent magnet. These vibrations happen so fast that we can barely see them, but the membrane moves the air around it, translating electrical frequencies into audible waves that we can hear. Take a good look at the diagram and stencil on the other side of this sheet so that you understand what variables will influence the efficiency volume of your speaker coil before designing your own. Iron a square of fusible interfacing to the back of the piece of fabric that you plan to embroider your speaker coil on.
