Recommended A mplifier Power For satisfactory performance, we recom- mend an amplifier with a power rating of five to fifty watts for the BG-525. Curiously, most speakers are not damaged by large amplifiers but by small amplifiers. If your system is playing loudly, a small amplifier will run out of power very quick- ly.
light switches and dimmers). V olume con- trols are connected in line with the speak- er, so you must connect the wire from the amplifier to the volume control and then from the volume control to the speaker. Speaker Wire Use 2-conductor speaker wire when con- necting BG speakers to your receiver or amplifier .
6 Speak er Placement The Boundary Effect Corners can affect the bass response of the speaker powerfully! This is called the boundary effect. Y ou will emphasize par- ticular bass frequencies and cancel out other bass frequencies when you place speakers close to the wall/ceiling bound- ary or a corner wall boundary .
This huge array of speakers assures that you will feel completely surrounded by the ambient soundtrack of the movie. Film makers try to use the “surround” soundtrack to envelope you in the envi- ronment on screen. They will place back- ground music, rain sounds, traffic noise, etc.
Inst alla tion F undament als Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing a Niles Blueprint Series speaker in your walls, consult a Niles dealer or professional installer. They have special tools, techniques, and experi- ence to make the impossible possible.
Try to line the holes up perfectly, because it makes pulling the wire much easier. A good technique is to snap a chalk line across the face of the studs or against the bottom of the ceiling joists. Then work backward so that you can always see the holes you have already drilled.
Identify where all of your electrical, phone, and TV wiring is likely to be and plan to route around it all. You can acci- dentally induce 60 Hz hum on your speakers if you run your speaker wire right beside electrical wire for more than a few feet. T ry to keep speaker wire running par- allel to power cables at least 3 feet away.
conduit, vents or drain pipe will be visible that give useful information. Choose the route with the fewest potential obstacles. If your house is built on a slab or you are wiring between two finished floors, look for baseboards which could be removed and replaced with the wire behind them .
12 Figure 6 Installation F undamentals In traditional wood stud / drywall construc- tion you can cut the hole for the speaker and utilize the large hole to auger holes across, up or down the wall for as far as your drill bit will take you.

ed of aluminum with a perfectly even powder coat overall. This powder coat is an ideal primer. Remove the grilles before painting. If you are using spray paint, use two thin coats without any primer . If you are using a compressor and a spray gun, use the finest, most diffuse setting.
Inst alla tion of Br acket s, F r ames and Grilles in Existing W alls IMPORTANT: Before you cut into any wall, review the sections on running wire and speaker placement.
the drywall section can be replaced clean- ly if there is an unseen obstruction behind the wall. BE VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE.
Installing the Speaker If the grille is already installed, remove it by using a bent paper clip or the tip of a corkscrew and pulling it away from the frame (See Figure 13) . 1 . Separate the speaker wire so that at least two inches of each conductor are free.
Oper ation Listening at Higher Volumes It requires more power to achieve a rea- sonable volume of sound in a large room than it does in a small room. It is possi- ble (even if you are not a teenager) to turn the volume so high that the amplifi- er runs out of power .
