GETTING STARTED

OVERVIEW

The Epos M Subwoofer is an active loudspeaker. In other words, it has an built-in power amplifier to boost the signal level. Therefore, there is no need for an external power amplifier to drive it. In addition, the M Subwoofer has a complex filter circuit which boosts sub-sonic frequencies and is adjustable to allow it to be matched to different room sizes, shapes and user requirements. The rear panel controls provide a range of adjustments for this purpose.

The M Subwoofer is designed to extend the low frequency response of both 2 channel and multi- channel systems, which each demand a very different tonal balance. This is described later, but control adjustment and placement in the listening room is important, so please read these instructions carefully for best results.

QUALITY

The M Subwoofer has a powerful 10" (254mm) loudspeaker driver, with enough magnet strength and voice coil size to handle very high power levels for long periods without distress. Its cone diaphragm is very stiff to keep distortion and colouration to a minimum. The rubber suspension surround is smaller than normal and quite stiff, which also helps to reduce distortion and low frequency over-hang. In short it has been designed to be more appropriate for a two channel bass unit than a conventional subwoofer.

To further boost the fidelity of the M subwoofer, it has a very stiff cabinet with extensive internal bracing, which is rarely found in conventional subwoofers. It has a completely separate section at the back of the cabinet to house the amplifier, which would normally be found in professional speakers and not in conventional subwoofers at any price. To further improve the sound quality Epos does not use port tuning to achieve boost bass extension, which avoids 'chuffing' air turbulence noises interfering with the fidelity of the speaker.

In short, the M subwoofer is very unusual and can be used to good effect to extend the frequency response of a stereo system of any quality or price.

INSTALLATION AND SETUP

Having established which power cord to use, select the correct mains voltage for your region with the selector switch on the back panel. (If in doubt, please read Page 1 again or ask your supplying dealer for advice). If neither of the two cords supplied are correct for your mains supply socket, do not proceed until you have contacted your dealer for advice or assistance.

Positioning the subwoofer is important if the best results are to be achieved. Place the subwoofer where it can be connected easily to the mains power supply and to the output of the receiver or stereo amplifier used for the rest of your system. Whilst this would normally be close to the system, be prepared to move it around the room to gain the best results.

The Epos M Subwoofer is a ‘down-firing’ speaker that has four purpose made legs that hold it 50mm above the floor. It also has a plinth that fixes to the ends of the feet with long bolts and covers the entire bottom of the speaker. Make sure the plinth is bolted to the cabinet with the Epos badge at the front. The plinth helps to prevent accidental damage to the exposed driver and also provides a stable platform for the speaker to stand on.

The mains supply can be left connected as it has a low current standby condition which is enabled when no signal is present for a short while.
