TRIO LS-800

Commentary

This speaker system was developed by refining the input / output conversion characteristics and technology in order to cope with PCM input devices and higher power amplifiers.

A 28 cm cone type woofer is installed in the low range.
A highly rigid cone with reinforced ribs and thermal shock treed cone with reduced inner loss is used for the diaphragm. In addition, an inverted cone-shaped acrylic resin-reinforced chamber is attached to the neck to reduce split vibration.

It has a flat unit of 10 cm in the middle range and 3.5 cm in the high range.
The plane radiator with high rigidity composed of acrylic resin and carbon fiber is used for the vibration plate, suppressing split vibration and obtaining more faithful piston motion.

Each range of each range is separated and arranged for one point grounding, and network crosstalk caused by voltage drop due to reciprocal induction between each coil and common ground wire is reduced.

We have clearly defined "diaphragm = something that should move" and "magnetic circuit = something that does not move", developed a tightening method with a unique tapered nut, and fixed the woofer and skoker.
In this method, a tapered nut is inserted between the frame of the unit and the baffle plate like a wedge, and it is tightened with a hexagonal bolt so that the unit is firmly fixed to the baffle plate.
In addition, Skoka eliminates the ambiguity of sound caused by vibration of the frame by attaching a tapered nut to the baffle plate near the magnetic circuit.

In the design of the enclosure, a woofer is placed in the center of the baffle to reduce harmful vibration, and a multi-sided backboard is used to increase rigidity while canceling harmful vibration in front and back.
