How to Guide

ongratulations on your purchase of a H-100II powered subwoofer. It will give your stereo system unparalleled low frequency output!

Bass frequencies are critical to realistic sound reproduction. After you’ve hooked up your H-100II, you will discover just how much

punch and depth you’ve been missing. No matter what kind of music or videos you listen to… whether you listen to them loud or soft,

you will experience sound that is richer and fuller. Bass guitar and string bass will have more impact. You will be able to FEEL as well

as hear percussion – just the way you would at a live performance. If you have an audio/video system, movies will come alive with

thunderous sound effects that were never possible without the H-100II.

This manual will take you step-by-step through the setup and operating process of your H-100II. Reading this manual carefully will

ensure you get maximum performance from your H-100II.

UNPACKING

Remove the H-100II carefully from its carton to prevent any scuffing or scratching. Take a moment to inspect for any shipping damage.

If you discover shipping damage, please contact your dealer and the shipping company immediately.

Please make sure to keep your sales receipt, it will establish the duration of your warranty.

PLACEMENT

Placement is extremely important because it dramatically affects the bass quality. An optimally placed subwoofer is much more pow-

erful and nice sounding than a poorly placed one. Three factors need to be considered:

1) Distance from your main speakers – The best placement for your subwoofer is on the same wall as the main speakers. How-

ever, if you are not able to place your subwoofer on the same wall as your main speakers, avoid placing the subwoofer halfway

between the front and back walls. This is where you get a strong null from your room’s standing waves. No matter how powerful the

subwoofer is, there will not be as much bass around the center of the room.

2) Distance from a wall outlet – Since the subwoofer requires AC power, it must be placed within 10 feet of a wall outlet. We

don’t recommend extending that range with an extension cord.

3) Positioning and Proximity to walls and corners – Physical placement of the subwoofer will have a definite impact on the

frequency response and the perceived amount of subwoofer bass output. Because low frequencies have long wavelengths, they are

influenced by proximity to a boundary such as a wall or floor.

(See Drawing A below) When you place the subwoofer well away from a wall, it will produce bass at a certain level. Move the

subwoofer close to the wall, it will produce more output (about 3dB more). Putting the subwoofer in a corner will increase output

another 3dB (6dB more than when placed away from walls and corners). The main thing to remember is you can place your subwoofer

in many areas of your room dependent on how much bass you want. If you like a lot of heavy bass, put the subwoofer into a corner.

If you like smoother, less obvious bass, move the subwoofer out into the room.

Since low bass waves are very large (up to forty feet or more across!), they tend to cancel and reinforce each other, causing places

in the room where there are lots of bass and other places where there isn’t very much bass at all. To locate the best place in your

room to put your subwoofer, you can use a technique called the “subwoofer crawl”. First place the subwoofer where you will be

sitting (ex. couch or chair) in your listening area. Turn on music with steady/constant bass and walk around the room at/near knee

level until you find the place where the bass sounds most accurate and balanced. This is where the subwoofer should be placed.
