LS series air core inductors
High-grade inductors employing
‘Hi-µ core’ with less DC resistance and low distortion.
Attenuators
High-input resistant attenuatorR80B, and coaxial versionR82B. 1dB step level adjustable
high-grade trans-type, R100T.
P-30 brass tweeter stand
P-30 is the tweeter stand made of brass,
which minimizes unwanted resonance
and improves high frequency sound.
P16 HP sound reflector
HP sound reflector eliminates the standing waves
in enclosure. HP’s 3rd-order curved surface
structure is ideal form and strength to extinguish
naturally the standing waves by making sound
reflected diffusely.
