1 HIGH PERFORMANCE SUBWOOFERS MODELS PSW10D AND PSW12D OWNER S MANUAL

2 Congratuations on your purchase of the Prestige High Performance Subwoofer. The Prestige Subwoofers are designed to provide you with high quaity Bass reproduction required to make your car audio system perform to its fu potentia. PRESTIGE Subwoofer Features Dua 4Ohm voice coi for maximum fexibiity and performance LowQ parameters for Isobaric and sma seaed box encosures Vented magnet for improved performance Godpated binding posts that can accept up to 10gauge wire Long throw suspension assemby Poycarbon woofer cone SUBWOOFER PARAMETERS PSW10D PSW12D Nomina Power Rating 225 Watts 260 Watts Maximum Power Rating 450 Watts 525 Watts Ferrite Magnet 30 Ounce 40 Ounce Frequency Response 20 Hz2.5 khz 20 Hz2.5 khz Resonant Frequency (F/O) 32 Hz ± 20% 20 Hz ± 20% VC Diameter 1.5" 2.0" Sound Pressure Leve 89 db ± 1.5 db 90 db ± 1.5 db Xmax 6mm 7mm Nomina Impedance 4 Ohms x 2 4 Ohms x 2 DCR 3.7 Ohms 3.4 Ohms Speaker Weight 3.0 kg 4.3 kg WARNING: DUAL VOICE COIL WIRING Highpowered car audio systems may produce sound pressure eves that exceed the threshod at which hearing oss may resut. They may aso impair a driver s abiity to hear traffic sounds or emergency vehices. Use common sense and practice safe istening habits when istening to your audio system. CAUTION: Never connect ony one voice coi of a dua voice coi woofer. Both must be driven at the same time for proper operation. Never connect an ampifier to an impedance oad ower than it is rated to hande. SERIES/PARALLEL MONAURAL CONNECTION Parae wiring for a singe, duavoice coi 4Ohm woofer in a monaura system wi resut in a tota impedance oad of 2 Ohms at the ampifier, (See Fig. 1) if your ampifier is rated to drive 2 Ohms in bridged or onechanne operation. If each of two duavoice coi 4Ohm woofers are connected in parae and then wired to 2

3 each other in parae, a 1Ohm monaura output woud resut (See Fig. 2). On the other hand, if your ampifier is rated for 4Ohm operation in bridged or onechanne operation, seriesconnect the woofer voice cois (See Fig. 3). If the ampifier is rated for 8 Ohms, interconnect the voice cois of the woofer in series as shown to obtain an 8Ohm monaura output (See Fig. 4). PARALLEL SERIES 2 Fig. 1 Fig. 3 Fig. 2 1 Ω Fig. 4 SERIES/PARALLEL STEREO CONNECTION Series wiring of each of two, dua voicecoi 4Ohm woofers wi resut in a tota impedance oad of 8 Ohms at each channe of the ampifier (See Fig. 5). Otherwise, connect one woofer to each channe for 4Ohm stereo operation (See Fig. 6), or two paraewired woofers (oneperchanne) for 2Ohm stereo operation (See Fig.7).

4 SERIES/PARALLEL CONNECTION USING THREE WOOFERS Three dua 4Ohm voicecoi woofers can be connected in such a way as to produce a 0.66Ohm (See Fig.8) or 2.66Ohm monaura output as shown beow (See Fig.9). Fig Ω 2.66 Ω Fig. 9 INSTALLATION RECOMMENDATIONS To reaize the utmost in sound reproduction from your subwoofer(s), foow these instaation recommendations: Use a quaity arge gauge wire to connect your subwoofer to the ampifier Use a subwoofer crossover to remove unwanted higher frequencies Position the encosure in the rear of the vehice with the subwoofer facing rearward to improve bass response and avoid canceation of audio frequencies ENCLOSURE CONSTRUCTION RECOMMENDATIONS To enhance subwoofer performance, the foowing genera recommendations shoud be addressed when constructing the speaker encosure: Use 3/4" MDF for your construction materia Gue a joint seams Screw or nai a joints tight Brace a was 4

5 DESIGNING AND BUILDING YOUR SPEAKER ENCLOSURE The foowing parameters are offered to assist you in designing your own encosure. There are many computer software programs avaiabe on the market that, aong with this information, wi aow you to construct the type of encosure that best suits your needs. To obtain the best possibe resuts, we suggest you use our recommended encosure designs and have an automotive sound professiona buid your encosure.
