Congratulations! Thank you for choosing a Niles loudspeaker. With proper installation and operation, you'll enjoy years of trouble-free use. The PSW800 wall mount subwoofer is uniquely designed to provide unobtrusive low frequency 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 Benefits The PSW800 In-wall subwoofer includes an easy access, baffle mounted high-pass filter to pre- vent over-excursion of the satellite ’ s woofers. The PSW800 In-wall subwoofer includes an easy access, baffle mounted low-pass frequen- cy selection switch. Figure 2 Figure 3 F eatur es and Benefit s Mica-Filled, Dual Voice Coi[...]

Inverted Dust Cap The inverted dust cap feature of the PSW800 actually reinforces the cone to fur- ther increase the stiffness-to-mass ratio and reduce distortion. In a subwoofer applica- tion, this dust cap inversion offers the addi- tional benefit of reducing the “oil can” effect that can cause traditional woofers to pro- duce unwanted high f[...]

Ho w Man y Subw oof er s? 4 Ho w Man y Sub w oof er s? For most applications a single PSW800 ’ s is appropriate. However, in large rooms, high performance listening rooms or in home theaters, an array of two or more PSW800 will deliver astounding results. Unlike other subwoofer systems, a Niles Subwoofer Array is concealed. Consider the distance [...]

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 PSW800 and connected to the Input connectors. A two conductor wire is connected to eac[...]

6 Connections Now, the volume control will raise and lower the volume for the subwoofer 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 wire[...]

Impedance With One or Two Subwoofers When one or two PSW800 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 t[...]

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 PSW800 con- nected to a pair of four ohm satellite speakers). Th[...]

T r eat ment & Placement 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 undament als 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 Fundament als 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 Fundament als 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 Fundament als 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[...]

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 800 New Construction Bracket The hole saving bracket enables a faster and cleaner final installation of the speaker. It forces the drywall installer to cut out the spe[...]

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[...]

10. Setting the High-Pass Filter When the “ SAT ” filter is in the CUT posi- tion, all of the bass energy will be pro- duced via the PSW800. When the switch is in the FULL position, both the satellite speakers and the PSW800 will reproduce the bass signal. Typically, satellites with woofers that are 5-1/4 ” or smaller will sound best with the[...]

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 half way between the two satellite[...]
