If your set of speakers is built by Linn Audio of New Hampshire then you are in for a real treat. These speakers tower at 7 feet tall and have the most crystal clear sound you have ever heard. How does Linn Audio create such amazing audio components? It begins with a passion for the clean sound of the high fidelity experience coupled with 45 years of expertise building and engineering custom sound systems.</p><br> <div id="pic"><IMG src="/images/success/cs/Linn audio/1.jpg" width=227></div> <p>The Linn Audio <a href="http://123triadpro.com/triad09/linn_audio/version-1/reference_granite.html">Reference Granite</a> speaker system is the culmination of decades of research and development, as well as countless hours of expert and critical listening. The founder of Linn Audio, David Linn, has a lifetime of experience with high-end audio equipment, having worked in the audio industry starting way back in 1965 when he was a sales rep for JBL. Mr. Linn has not forgotten the design principles and objectives of the JBL engineers. He utilizes many of these same principles today. The Reference Granite system was designed around some of the classic JBL principles, including large, paper cone woofers with 4" voice coils and a mid-range horn with a large compression driver. Mr. Linn has since had training as an Electrical Engineer, and has applied all his engineering training and expertise, as well as a lifetime of listening and enjoying high-end stereo, to the development of his speaker systems.</p> <br> <div id="pic"><IMG src="/images/success/cs/Linn audio/18.jpg" width=227> </div> <p><strong>The Passion for Perfection</strong></p> <p>Mr. Linn has an obsession with eliminating distortion in his systems. He has done everything conceivable to minimize or eliminate distortion from the Linn Audio line of speakers. There is no such thing as "zero distortion," especially in speakers, but Mr. Linn believes that his speaker designs come as close as can be found in the high-end speaker market, regardless of price. "Transparency" is a word that he also uses to describe his speaker designs. In other words, nothing gets in the way of the music, and it is as close as you can get to the original performance.</p> <p><strong>3D Design and Quality Construction</strong></p> <p>After researching different ways to make the speaker cabinets and visiting with dozens of cabinet makers, Mr. Linn decided that he would have to create the custom speakers himself, mostly because his unique design could not be made using traditional hand tools. After buying a CNC machine he found Alibre Design online and starting using the free trial. To drive his CNC machine he purchased Alibre Design and Alibre CAM to make what he calls the "asymmetric hexagon" design of the cabinet. He designs the panels of the cabinet in Alibre Design and then uses Alibre CAM to machine out the parts. "I like how in Alibre Design you can draw a rough sketch of the part you need to make and then go back and dimension it to exact specifications," Linn says. Alibre CAM then sends the cutting toolpath in the form of G-code to the CNC Machine which cuts the pattern of internal and external components of the speaker cabinet. The inner cabinets are constructed with multi-layered Medite MDF, then cross-braced and glued under pressure to eliminate any resonance. After the panels are constructed he applies high-end wood grain finishes that can be customized for the interior design elements of the home theater. All parts of every speaker, cabinet materials, drivers, crossover components, wiring, damping materials, are selected for sonic quality. All drivers are selected for their sonic merits and construction quality. All crossover components are constructed to eliminate any distortion, and every crossover component is supplied by premium parts suppliers. Internal wiring is audiophile quality from the best manufacturers of silver conductor wire, and connections are point to point, soldered with silver solder. The result is a beautiful piece of furniture, and sounds to satisfy the most demanding music lover. The systems are all completely handmade, in the USA.</p> <p>Visit <a href="http://www.linnaudionh.com/ ">www.linnaudionh.com</a> to see the <a href="http://123triadpro.com/triad09/linn_audio/version-1/reference_granite.html">Reference Granite</a> Speaker System </p><br> <div id="pic"><IMG src="/images/success/cs/Linn audio/speakercabinet.jpg" width=227> </div> <p><strong>Reference Granite Speaker Specifications</strong> <ul>Enclosure type: Front ported</ul> <ul>Woofer: Two - 15"</ul> <ul>Midrange: One - compression driver/horn (1" throat)</ul> <ul>Tweeter: Ribbon type</ul> <ul>Sensitivity: 97 db overall for mono-amp; 107 db on high end, when bi-amped</ul> <ul>Nominal impedance: 4 ohms, when mono-amped; 8 ohms on mid-range when bi-amped</ul> <ul>Maximum Power: 1000 watts </ul> <ul>Frequency response +/- 3 db 19hz - 40khz</ul> <div id="pic"><IMG src="/images/success/cs/Linn audio/speakerfront.jpg" width=227></div> <ul>Overall dimensions: <ul>Height: 82 &#189 " including feet.<br> Width: 27" at widest point,<br> Depth: 26"</ul></ul> <ul>System weight per channel: 450 pounds</ul> <ul>Total shipping weight: 1000 pounds</ul> <ul>Suggested retail price is $ 49,500 per pair</ul> <p><strong>Software Used:</strong> <a href="https://www.alibre.com/products/ad.asp">Alibre Design Standard</a> & <a href="https://www.alibre.com/products/ac.asp">Alibre CAM Standard</a><br> <p>Available at <a href="http://www.linnaudionh.com">www.linnaudionh.com</a> & <a href="http://www.higherfi.com/search_linn/1 ">www.higherfi.com</a><br> <p><strong>About Linn Audio of New Hampshire</strong><br>Linn Audio is located in the "Granite State", New Hampshire, and has been building custom loudspeakers for clients for years.
