==={{L1 nl}} versus {{B1 nl}} Fall Off Over Distance=== | |||
Hi folks, | Hi folks, | ||
As many of you know first-hand, nearby direct sound from the {{L1}} falls off with distance more slowly than most other speakers, including all bass speakers, and including {{B1}}s. We rarely notice this difference indoors, because room modes in the bass impose large changes from place to place that dominate over the different rates of fall-off of the direct sound waves from the {{L1}} and {{B1}}. | As many of you know first-hand, nearby direct sound from the {{L1}} falls off with distance more slowly than most other speakers, including all bass speakers, and including {{B1}}s.

But before you invest in more B1s, make sure you are getting all the bass you are entitled to from the ones you have. For stereo music playback, you can get a little more bass by stacking your left and right B1s tight together. Outdoors, if there is a hard wall nearby, you can get a good deal more bass by placing all the B1s right at the wall. If you can't get right to the wall, then keep the B1s at least 7 feet away from the wall. If you place B1s outdoors anywhere from 2 to 7 feet from a hard wall, you will get a big hole in the bass response--bass notes will be very weak at some pitches while other pitches will be okay. The reduction in bass in that case will be significant. Try to avoid such placement if you can. | But before you invest in more B1s, make sure you are getting all the bass you are entitled to from the ones you have.

Overall, outdoor settings demand more from your sound system in the bass than indoor settings, because outdoors there is no bass reinforcement from a room. Also, people are often farther away outdoors. Both factors lead to your often needing more B1s outdoors than indoors. So John L is probably right in his first post--he may need more B1s, but | === Getting the Most from the B1s === | ||
