Congratulations! Thank you for choosing a Niles loudspeaker. With proper installation and operation, you'll enjoy years of trouble-free use. The PSW8 wall mount subwoofer is uniquely designed to provide unobtrusive low fre- quency augmentation.
2 Fea tur es and Bene fits Figure 2 The PSW8 In-wall subwoofer includes an easy access, baffle mounted high-pass filter to prevent over-excursion of the satellite’s woofers. It also has an easy access, baffle mounted low-pass frequency selection switch.
High Power Handling The PSW8 employs an exceptionally heavy- duty magnet/voice-coil/spider assembly that is capable of handling high power ampli- fiers (up to 1 50 watts). Infinite Baffle Design The PSW8 is designed for optimum low fre- quency reproduction in a traditional 2 x 4 stud wall with varying air volumes.
Ho w Man y Sub w oof ers? 4 Ho w Man y Sub w oof er s? For most applications a single PSW8 ’ s is appropriate. However, in large rooms, high performance listening rooms or in home theaters, an array of two or more PSW8s will deliver astounding results.
Connections Single Stereo Subwoofer A four conductor wire (Left+, Left-, Right+ and Right- ) 1 6 gauge or larger is run from the amplifier location to the local volume control. (See Figure 4) . From the local volume control, the four conductor cable is run to the PSW8 and connected to the Input connectors.
6 Connections Now, the volume control will raise and lower the volume for the subwoofers and the left and right speakers simultaneously. Additionally, the crossovers are now con- nected so that the crossover switches can be adjusted to your requirements.
Impedance With One or Two Subwoofers When one or two PSW8 subwoofers are connected to the satellite speakers, the overall system impedance to the amplifier lowers. System Impedance in Ohms ( Ω ) One or Two Subwoofers 8 Ω Sats 4 Ω Sats 1 Sub 4 Ω 2.
Using Speaker Selectors With Standard Volume Controls In multi-room systems with standard vol- ume controls any Niles speaker selector will maintain a four ohm load if you leave one set of room outputs unused for every speaker system with an impedance of less than four ohms (such as a PSW8 connect- ed to a pair of four ohm satellite speakers).
T r eat ment & Placemen t Typically, sheetrock encloses the sub- woofer in most installations. Sheetrock has a fairly loud resonant “ twang ” compared to the rigid non-resonant enclosures of most floor standing subwoofers.
Inst allation F undamen tals Introduction If you have doubts about whether you are capable of installing an in-wall speaker, consult a Niles dealer or professional installer. They have special tools, tech- niques, and experience to make the impos- sible possible.
11 Inst allation F undamentals 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.
12 Inst allation F undamentals 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.
13 Inst allation F undamentals plenum rated wire (check your local building codes, some municipalities require conduit). 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.
Inst allation in Ne w Constr uction Stage One: Before Drywall is Hung Insulating the Wall Cavity. If feasible, fill the wall cavity with insulation at this point . Mounting The Model 8 series New Construction Bracket The hole saving bracket enables a faster and cleaner final installation of the speaker.
15 Inst allation In Existing Constr uction Inst allation o f 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 18) . 1 . Separate the speaker wire so that at least two inches of each conductor are free.
Speaker Phase Speaker wire has two conductors. One conductor is attached to the negative (-) terminals and one conductor is attached to the positive (+) terminals of both your speaker and your amplifier. Usually , the wire is marked for your convenience.
19 Final Ins tallation In Ne w Or Existing Constr uction Setting the Subwoofer Low-Pass Filter With the “ Low Pass ” switch in the 1 00Hz position, the PSW8 will only reproduce bass below one hundred cycles. When the switch is in the 1 40Hz position, the PSW8 will reproduce bass below 1 40 cycles.
20 Remo val o f Speaker and Grille 3) Satellite Left-Right Phase Reversal If the right satellite is reversed in phase from the connections on the left satellite, you will hear reduced bass and a “ phasey ” dif- fused vocal image. If you suspect the sound is not right and you cannot see any mark- ings on the wire, try this simple test: 1 .
21 Oper ation Oper ation Congratulations A concealed PSW8 subwoofer installation frees you to use your tone controls, play the system loudly and enjoy deep extended bass, even if your satellite speakers are small.
