Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Is the Pioneer TS-300D4 single or dual voice coil?
A: It is a dual voice coil subwoofer with two 4 ohm coils (4 Ω x 2), which gives flexible wiring options to match your amplifier.
Q: How deep is the TS-300D4 and what cut-out does it need?
A: It needs 147 mm of mounting depth and a 281 mm cut-out hole.
Q: What enclosure volume does Pioneer recommend for the TS-300D4?
A: Around 35.4 litres (1.25 ft³), within a range of roughly 24.1 to 49.5 litres.
