Lab-1000
Commentary

Large Lab-series speaker system.

The Lab-1000 uses a separate top and bottom enclosure structure that allows the top enclosure to be moved back and forth and adjusted for listening orientation, and comes with a special stand to prevent low-range veils.

W-1000 which is 30 cm cone type woofer is mounted in the low range.
This unit uses a thread suspension type damper to eliminate the non-linear component that occurs with general cloth dampers.

The mid-range is equipped with a multi-seller horn type squaker.
In this unit, a guide bobbin is joined at the position opposite to the voice coil to a hard light alloy diaphragm attached to the back case in the direction opposite to the horn, and a nylon monofiber yarn rich in tensile strength is stretched in a straight contact. This yarn is a single twill yarn. The tension is strictly controlled and sealed with only one end of the pole, so that the tension on all three sides is automatically balanced. This prevents center misalignment.
By adopting the thread suspension structure, it is possible to use an exceptionally soft material for the edge of the diaphragm. This eliminates the relative lack of rigidity at the top of the diaphragm even if the edge is tangentialized or rolled in order to avoid reverse resonance in the horn type.

The T-1000, a multi-sellerhorn type tweeter, is mounted in the high range.
A stretched duralumin membrane diaphragm is used for the diaphragm of this unit.

Level control is provided for the middle and high frequencies.

The enclosure uses a multi-duct bass reflex system.
In the Lab-1000, the phase inversion operation can be adjusted by the attached sound absorbing material and port cover.
