Adding T900A super tweeter on this system, the briskness of mid-frequency gets better.FE208E Well tuned low frequency realizes tight and massive sound with perceptible fast response. This box plan is the full-fledged back loaded horn enclosure for FE208Esigma.

FOSTEX FE206EN ENCLOSURE DRIVERS
The Fostex FE206En drivers may need a passive EQ-network for best tonal balance. The 30mm thick sheets of BAF wadding should be placed as shown on the drawings.ĭrivers we have tested and found suitable for use in this system are the AER MkI, Fostex F200A and the Fostex FE206En. As always, with full-range drivers this material gives the most natural tone.
The best material to use for the cabinets is 18-19 mm birch ply. Sometimes it helps to add some more damping material if the bass is too boomy with a certain driver. If there is too much bass or "boom" then simply pull them out of the corner, or move them away from the back wall until you find the best balance. For more body in the bass place them closer to the back wall or even in the corner ( if you are using the lowest Q drivers). All you need to do is to find the place for them in your room giving the best bass response. The SINGULAR is a very easy loudspeaker to live with. Using only a few 30 mm thick sheets of BAF wadding (a soft synthetic fiber damping material) for damping, the system exhibits none of the honking character often associated with full-range drivers used in poorly designed horn systems. The system is tuned for maximum efficiency using as little damping material as possible.
More pictures and detailed building info can be found at: toeing the speakers to face the listener results in a rising response so id recommend listening off axis with no toe in at all and even some toe out depending on the. Instead, it is a combination of all these loading systems, resulting in a wide-band resonator effective from 40 Hz to 250 Hz. tonality if of course bright but with no toe in, Im able to have a flat response from 50hz up to 10khz. It is not a transmission line needing a lot of damping material to tame resonances. The SINGULAR is not a bass reflex design, which is only efficient for only half an octave. The basic design for the SINGULAR was initiated by Onur Ilkorur. If you like the sound of Fostex or Lowther drivers in a reflex cabinet you will love them in the SINGULAR, with its more efficient loading over a wider bandwidth. A full-range filter-less (depending on which drivers you use) design, it is easy to build, and offers very balanced performance when used with drivers having a Qts between 0.3 and 0.6 DIY Singular The SINGULAR is simplest speaker we offer.
