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. The selectable high and low-pass filters make it suitable for use with a wide variety of satellite s[...]

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. New Construction Wings Bracket Frame Speaker Baffle IR Knockout Grille F eat ur es and Bene fi[...]

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. It does not require a special encl[...]

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. Unlike other subwoofer systems, a Niles Subwoofer Array is concealed. Consider the distance bet[...]

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. A two conductor wire is connected to each [...]

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. You must adjust the crossovers on each subwoofer with this hook-up. Optionally, a jumper of wir[...]

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 2.6 Ω 2 Subs @8 Ω each 4 Ω 2.6 Ω 2 Subs @4 Ω each 2.6 Ω 2 Ω If the impedance is too[...]

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). The [...]

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. None of the following modifications are absolutely necessary, however any one or combina- tion of them will improve the[...]

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. The installer can provide you with an estimate before any work is done. Running the Sp[...]

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. Paying care- ful attention to this will save you a lot of time later on! Pulling the Cable Pull the cable in sections (fro[...]

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. T ry to keep speaker wire running par- allel to power cables at least[...]

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. If you have matching paint a[...]

Drill a 1 /8 ” pilot hole just barely through the wallboard or dry wall (1/2 ” to 5/8 ” deep in most homes) about an inch below[...]

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. IF YOU FEEL ANY EXTRA RESISTANCE AS YOU ARE CUT- TING, STOP . 4. If you are cutting into lath and plaster walls, use masking tape to outline your penciled marks, drill the four corn[...]

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. 2. Open the no-strip terminal by applying pressure to the red and black levers until an a[...]

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. There are different ways wires are marked: a stripe on one wire, a ribbed area of one conductor[...]

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. Depending on the size of the room, the type of [...]

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 . Stand[...]

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. When used with satellite speakers that have substantial bass of their own, the PSW8 tightens the deep tones and aug- ments the bass musi[...]
