1 Ohm at the amplifier, (See Fig. 1) if your amplifier is rated to drive 1 Ohm in bridged or one-channel operation. If each of two dual-voice coil 2-Ohm woofers are connected in parallel and then wired to each PSPL-10 PSPL-12 300 Watts...

other in parallel, a 0.5-Ohm monaural output would result (See Fig. 2). On the other hand, if your amplifier is rated for 2-Ohm operation in bridged or one-channel operation, series-connect the woofer voice coils (See Fig. 3). If the amplifier is rated for 4 Ohms, interconnect the voice coils of the woofer in series as shown to obtain an 4-Ohm mon- aural output (See Fig.
ENCLOSURE CONSTRUCTION RECOMMENDATIONS To enhance subwoofer performance, the following general recommendations should be addressed when constructing the speaker enclosure: Use 3/4" MDF for your construction material Glue all joint seams Screw all joints tight...
