Compact active subwoofer fits for combination with small active speakers such as PM0.3.

Features

● Best fit for our compact high sound quality active speaker PM0.3. With a height of 18.5cm, the same as PM0.3, and a width of 20cm, one pair of PM0.3, it is truly the active subwoofer you have been waiting for.

The PM0.3 is the most long-awaited active subwoofer, with a height of 18.5cm, the same as the PM0.3, and a width of 20cm, the same as a pair of PM0.3s.

(1) The speaker diaphragm is made of a heavy, rigid glass fiber material with a large mesh mesh, which allows for high output reproduction of solid heavy bass sound even in a compact body.
(2) The center cap is also made of the same high-rigidity glass fiber material as the diaphragm, and its φ64 mm concave shape ensures that it will not collapse under the large amplitude of the subwoofer.
(3) The enclosure is sealed to achieve both a compact body and speedy bass. Furthermore, the front baffle is designed to support the speaker section by adopting a corner wood structure, which enables reproduction of realistic low frequencies.

(4) A four-layer voice coil, which is heavier than the usual two-layer voice coil, is used. By controlling sound pressure in the mid-high range, low-frequency reproduction has been optimized.

● A high-efficiency 50W high-power digital amplifier is generously incorporated in the compact body. The power supply is built into the main unit, eliminating the need for an AC adapter, which tends to get in the way during installation.

● Equipped with a FREQUENCY knob for adjusting the crossover frequency (60 to 150 Hz) and a phase switch for inverting the phase.

Adjustments can be made according to various main speakers connected and the listening environment, including PM0.3 and PM0.1.

● The unit is equipped with RCA through jacks that allow input signals to be output to the main speakers, making it possible to listen with the main speakers alone (a stereo RCA pin cable <1.5m> for connecting the PM0.3 and other main speakers is included with the unit).

● If the audio input remains below a certain level (low volume) for approximately 15 minutes, the auto-standby function operates, reducing power consumption to 0.5W or less, and returns to normal operation when the signal is input again.

The auto standby function may not operate properly depending on the noise level of the device connected to the input terminals of the unit.
The standby mode may operate when the volume on the playback device is set to a low level. In such cases, increasing the volume of the playback device may improve the problem.

Best match for PM0.3 and PM0.1

By combining PM-SUBmini with our PM0 .3 and PM0.1 compact high quality active speakers, it is possible to add more powerful ultra-low frequency to the clear and natural sound.

Best match for Player's Monitor PM30G!

Subwoofers are what the player needs.

We recommend the PM-SUBmini for the PM30G, a monitor-thinking active speaker recommended for instrument players. The low frequency range is enhanced, making bass drums and basses sound even more comfortable.

FAQ

Q
How do you decide which PHASE switch to use?
A

When using this unit in combination with our PM0.3 or PM0.1 active speakers (especially when the speakers are installed side by side), the PHASE switch can be left in the 180° position, but depending on the installation location, the 0° position may sound more natural. Please listen and check by switching the PHASE switch to whichever provides the most natural sounding playback.

Q
The unit automatically goes into standby mode in the middle of playback, is this a malfunction?
A

This is not a malfunction but a specification for power saving (auto-standby function). European ErP Directive, a regulation that mandates environmentally friendly design.

Powered speakers and power amplifiers equipped with the auto-standby function shift to standby mode when the volume remains below a certain level (not necessarily silence) for a certain period of time. The power will be restored when the input signal exceeds a certain level of loudness.

In some cases, the problem can be avoided by increasing the volume on the playback device.

Q
Can I connect and use speakers and AV amplifiers from other manufacturers?
A

This product is designed to match our PM0.3 and PM0.1 active speakers.

However, depending on the combination of products connected, it may not work properly due to level matching with the AV amplifier, or the original performance may not be obtained, or the sound connection may seem unnatural, etc. Please be aware of this.

Also, when connecting to the subwoofer output or preamplifier output of an AV amplifier, the PM-SUBmini’s auto-standby function may be activated if a sound source with a low low-frequency volume is played for more than a certain period of time. If the auto-standby function is activated during playback, it may be possible to avoid this problem by using a model that allows the volume control of the subwoofer output to be set separately from the main output, and by turning up the volume of the subwoofer output.

Note that this problem cannot be avoided with AV amplifiers that do not allow the volume of the subwoofer output to be set separately from the main output.

Please note that we have not tested this product in combination with other companies’ products.

Q
The preamplifier has only one subwoofer output jack, but the PM-SUBmini has two input jacks (L/R). How should I connect them?
A

Connect to either L or R. It is not necessary to connect to both L/R terminals.

Most subwoofer outputs on preamplifiers and other equipment mix L/R signals internally, and the PM-SUBmini does the same internally.

This is because it is generally believed that the human auditory system has difficulty localizing low frequencies, and subwoofers are often used for monaural playback.

This does not mean that there is no localization in the low frequency range. In some systems, subwoofers may be used in stereo.
