Hand crafted active bookshelf speaker system, designed and built by Riaz Missaghi
These speakers use a waveguide making them very directional and thus best suited for monitor purposes. To that end they are calibrated to within 1db of a flat amplitude response from 50hz to 20khz.
Made from one and half inch thick laminate Baltic birch panels for their superior accoustics, and soft appearance. The front and back of the reciever is 1/4 inch aluminum plate, and the terminals are gold plated.
To make the system perfectly flat it uses four channels of amplification and a digital crossover all integrated in an attractive box with a switch, power light and volume knob. It will look great on your desk or bookshelf
You can connect these to anything with a headphone jack or via RCA cables. All power, speaker, and input cables are included. They are loud enough to have a dance party in your living room.

While many studio monitors claim to supply a flat response curve the truth is that they are measuring the sum of the both the fundamental sound and all the unwanted sub-harmonics that are created by the drivers in the speaker and did not exist in the original recording. When auditioning a new set of speakers if the words ”vivid”, “clear”, or “lush” ever come to mind then it’s most likely that you are hearing the speakers harmonics and not just the source material. Harmonic distortion is the leading cause of listening fatigue , it may sound exciting on the showroom floor, but it will wear you down quickly. A speaker with a true response should actually sound, well, boring really, because it doesn’t add or subtract from the music, it should just recreate it’s signal and get out of the way. We achieve this in two ways. First the drivers are selected primarily for strong fundamentals, not nessesarily flat response which can be easily tailored later in the crossover, we don’t have a big RD department, rather we rely on the most respected third party hobbyists who sacrifice their time in the name of unbiased science* Second we recess the tweeter with a mild wave guide, this boosts the fundamental so that we can lower the energy put into the tweeter resulting in much less excitement of it’s driver memberane making it sound really clear, as if the wool has been pulled from your eyes.
The last main consideration, after response and harmonics, is phase. This means that when a drumstick hits a drum in a recording the wavefront of the bass and the treble should hit you at the same time. We phase align the drivers with their positioning and digital delays of 0.06ms, this minimizes combing and keeps the sweet-spot in front of the speakers. We use a 24db/octave Linkwitz-Riley crossover to maintain phase in the signal path. An finally we have optimized the position of the diver on a well rounded baffle to ensure that reflections from the baffle evenly dispersed and not concentrated at any specific frequency.
The use of an active crossover greatly simplifies design of the system and allows larger flexibility in driver choice and crossover point so that no compromises have to made in those critical elements. There is also the huge benefit of having the driver directly coupled to the amplifiers, in fact the bass driver is so strongly coupled that when the system is on the front cone is almost immovable where as when off it gives way to a light touch.
