Characteristics Chart

Output sound pressure level measured in the anechoic room

The LOW-PASS FREQ. control knob adjusts the frequency curve as shown in the graph below. The characteristics are measured with PM-SUBn in sole use.

The graphs below show the characteristics when PM-SUBn is connected to PM0.4n and PM0.5n. Setting the PM-SUBn SUBWOOFER VOLUME and LOW-PASS FREQ. at the position below achieves the best sound performance indicated by the thick line in the graph. The output sound pressure varies depending on room acoustic characteristics and the PM-SUBn/main speaker system installation position. Referring to the setting example, set the best volume position so that the low frequency output from both PM-SUBn and the main speaker system is coordinated.

Main Features

Active sub woofer with a closed cabinet optimized for PM0.4n

The enclosure volume is downsized by 25% comparing to PM0.5SUB (MK2). This allows PM-SUBn to install more flexibly. With the closed cabinet, you do not have to pay attention to the bass-reflex enclosure duct direction.

A long-stroke 20-cm speaker unit exclusively designed as a sub woofer

A light BKP (Bleached Kraft Pulp) and strong Kevlar fiber mixed material is used for the cone paper of the speaker. Also a highly durable, light and high internal-loss SBR system foamed rubber is used for the speaker surrounding.

A closed wooden cabinet with a shining front baffle painted in glossy-black and optimized stiffness establishes a high-quality sound reproduction.

Driving a sub woofer with 68W high-power amplifier

The RCA pin and phone are employed for the INPUT/THRU OUT jacks. The stereo RCA pin cable (1.5 m), stereo mini - RCA pin cable (1.5 m) and 2 x phone - phone cables (2 m) are provided as standard accessories. Without purchasing extra cables, you can connect PM0.4n/PM0.5n and PC with PM-SUBn. The volume, cross-over frequency (50 ~ 150 Hz) and the phase (0º or 180º) can be adjusted for your usage environment.

PM-SUBn can be used for various applications such as DTM and home theater.

About switching PHASE

The sound pressure level varies between the 0º and 180º PHASE SW position. In a normal environment, setting the PHASE SW at 0º rather achieves a flat characteristic. However, depending on an installation position and a distance between PM-SUBn and the main speaker system, there is a case that setting the PHASE SW at 180º realizes a smoother reproduction from low to high frequency region.
