There is something magical about the combination of Single Ended Triode Amplifiers and High Efficiency Single Driver Full Range Speakers. Such a system provide the most detailed rendition of vocal and instrumental music.
Full range drivers have a class of its own. Typically these drivers have a very strong magnet driving an ultra light cone with precise control on the cone movement. It is this aspect that give these drivers the ability to reproduce the subtle nuances of music - the low level details as well as the snappy dynamics that's a hallmark of full range drivers. However, due to the extremely small excursion of the cone, most full range drivers need reinforcement in the low frequencies through specially designed enclosures. Transmission line and rear loaded horn designs work best with such drivers.
My initial effort was to build a slightly modified version of the Haruna design on the Frugal Horn website for the Fostex 166 En driver. The Haruna is a wonderful design by Scot Lindgren and Dave. Its a double mouth stepped expansion horn. I modified the compression ratio of the throat and the volume of the coupling chamber to my individual liking. I paired these speakers with the Lyrita 2A3 SET designed by Mr. Viren Bakshi. Together they have been putting up a stellar performance. The speakers simply disappear and the music flows from a dark background in the most coherent, lifelike presentation one could ever experience. Music that is alive, music that connects with you emotionally. The low level details, the imaging of the soundstage and the rendition of the texture of voice and instruments are simply stunning. Being a double mouth design the enclosure loads both the ceiling and the floor and as a result the bass surrounds you. Its rich, deep, open and musical without the slightest trace of lumpiness.
But that's the beginning of the journey. The sheer performance of the Haruna design intrigued me to dive deeper into horn loudspeaker design and it has been several months of serious work in understanding the physics of horn design. A spreadsheet application for designing horns has been developed and the first design from ground up is in the prototype stage. I have christened it the name Serenata.
Horn loudspeakers had fallen out of vogue for more than 7 to 8 decades due to its extremely complex design, the large size and the resultant high cost. This is an effort on my part to rediscover the unmatched beauty of these designs.
I would be happy to invite audio enthusiasts in this forum for an audition and feedback for improvement of the design.
