Woofer Speaker Fact or Fiction

Video Transcript

"Hey guys, we're going through fact and fiction over woofers. Fact number one, this is a box, just joking though. We're actually going to go over the myth of polyfill. Now polyfill, a lot of installers, informed hobbyists, everybody will say, installers and hobbyists will say you need to put polyfill in every single box. Now most people don't even know the reason why people put polyfill in a sub woofer enclosure. Its to fool the woofer in to thinking it has a little more volume than it does, not to dampen the box or make it sound deeper or tighter or all the different theories that people have. Its just for enclosures like this that are very small air space, they have a driver that actually need, require more sealed air space than what's specified in this enclosure. Put polyfill in the box and it'll fool the woofer in to thinking it has a larger enclosure. Without going down to theory and conjecture, that's what its used for. Its not used to make the driver sound better. Its not used to make the woofer sound dampened or deeper or cleaner. That's the use of polyfill. For everybody out there, installers, technicians, hobbyists included. Next fact and fiction, DVCs are not necessarily louder than single voice coil woofers. That's also another common misconception. Single voice coil woofers and dual voice coil woofers are used to versitile or modem PDs. Dual voice coils and single voice coil drivers are out there that handle the same loads of power, they're just different. Dual voice coil woofers give you a choice between watt up and down. A standard four ohm woofer you have to bridge with more single four ohm or single eight ohm or single six ohm or single two ohm woofers to desire the lowered or upped affect.And that's fact or fiction for you today folks."
