Vintage KEF LS3/5A monitor speakers. In excellent condition.

An 11 cm KEF B110C type SP1228 unit is used for the middle and low frequencies up to 3 kHz, and a T27SP1032 tweeter is used for the high frequencies.

In order to completely seal the inside of the enclosure and make it airtight, PVC sheet is used on the edge of the woofer, and the unit is decoupled and sealed.

The network section consists of 26 carefully selected high-quality parts. Each speaker is individually adjusted by computer simulation, and the characteristics of the entire system are strictly controlled within ± 0.25 db of the BBC specification.

The front baffle is made of felt material around the unit to eliminate interference caused by vibration of the cabinet.

The enclosure is made of 12-mm-thick birch material, which is well known as a piano material and has excellent strength. In addition, beech wood is used as a splint for the joint part to increase the internal strength.
