When added to a system with full-range satellite speakers the NEAR® IGS100M subwoofer adds the last half-octave of bass foundation that makes music really come alive. The IGS100M is an updated and improved version of the original IGS10. The new model features a retuned port and alignment to deliver even better low frequency “kick” than its predecessor. At the same time the IGS100M remains musical at any playback level and is capable of withstanding high output use.
The NEAR® IGS subwoofers look and sound great when used as freestanding on-ground speakers that can be camouflaged among planters and pots. But we primarily designed them to be partially buried in the ground, affording homeowners superior sound performance, lower visibility and ultimate security.
The packed earth around the speaker dampens enclosure wall resonances to zero, allowing all of the woofer energy to go into moving air rather than the cabinet. In-ground installation also reinforces bass response by providing an infinite baffle to focus the sound waves. The bass impact is visceral, precise and detailed.
The IGS100M’s driver is a dual 8-ohm voice coil design that allows you to feed separate Left and Right channel inputs for summing a stereo feed into one woofer. This feature is a big help when the amplifier does not have a dedicated summed subwoofer output and you want to use only one IGS100M. When a summed L+R channel feed is available from the amplifier, parallel wire both voice coils to achieve a 4-ohm load. For filling really big spaces with high impact bass, use two IGS100Ms.
Like other NEAR speakers, the IGS100M is truly weather-proof, not just “weather-resistant” and can be used totally exposed to the elements. The IGS100M enclosure is color-through, Linear Low-Density Polyethylene that sheds moisture, dirt and chemicals. The UV inhibitor pigments are embedded uniformly throughout the material so the sun won’t fade or yellow the color and garden tools won’t mar the speaker’s great looks.
Superior Technology, Superior Sound
The IGS100M utilizes an MDT metal alloy
diaphragm woofer with dual voice coil UDIO technology
along with the Magnetic Liquid Suspension (MLS)
technology patented by New England Audio Resource in 1993.These are the same materials and technologies employed throughout the IG Series to ensure timbre consistency and system design flexibility.
The IGS100M’s 10-inch driver is loaded into a sealed bandpass enclosure – the perfect solution to the challenges of delivering bass reliably outdoors. In 1998 Bogen Communications, Inc. on behalf of its NEAR division, patented this concept of in-ground bandpass subwoofers, a technique that is widely copied today.
In a bandpass design the woofer sits in a sealed enclosure – perfect for protecting the business end (motor, voice coil, suspension) from outside contaminants such as moisture, debris and wildlife. The better protected front (cone) side of the woofer fires into a ported enclosure to take advantage of the high acoustic efficiency of a vented alignment. In this way the IGS100M is the best of both worlds – sealed and vented.
Perforated aluminum screens prevent critters from entering the vented chamber. And of course, the MDT cone
and SupraPolymer surround
are impervious to whatever humidity, chemicals and contaminants could enter the vented chamber.
The IGS100’s bandpass alignment is by nature bandwidth limited and requires only a gentle slope external low pass filter. We recommend using the Low Pass Filter built-into the NEAR XL Series power amplifiers.
The result is exceptional sound quality that rivals audiophile-grade indoor subwoofers. NEAR’s high tech components ensure that everyone on the deck or patio hears well-balanced, lifelike sound at every volume level without fatigue.
