It’s true that standard (single voice coil) subwoofers are fine for many systems. As a reminder, never assume your amplifier is bridgeable – always check! Dual voice coil subwoofer advantages Most, but not all, higher power car amplifiers are bridgeable while home stereo amplifiers in many cases aren’t. How many speakers/subwoofers you’ll be using.Whether your amp is stereo only or bridgeable.The minimum speaker load (Ohms) rating of your amplifier.When it comes to choosing one or the other, the answer is “it depends.” Whether or not you should use single or DVC subwoofers depends on a combination of things: There isn’t a “best” choice when it comes to single or dual voice coil speakers & subwoofers. Single vs dual voice coil subs: which is better? Thiele/Small parameters are just the highly detailed technical characteristics of a speaker that help know how it behaves in certain speaker boxes or audio crossover designs. If you’re into speaker box design, it’s helpful to know that dual voice coil speakers often have slightly different Thiele/Small parameters. Power handling ratings are usually very similar (always double-check to be sure) but might be a bit different. In most cases, dual voice coil subwoofers are slightly more expensive than the same model with single voice coil design – but not by very much. However, there are definitely some really nice advantages I’ll explain later. There aren’t any direct performance differences between a single and dual voice coil model of the same design. Do dual voice coil speakers have performance differences? Single voice coil subwoofers have only one speaker voice coil winding while dual voice coil models have a 2nd voice coil of the same Ohm rating (impedance) added in the bobbin.Ī 2nd pair of wire leads and speaker wire terminals are added, too. Voice coil wire leads & connection terminals.Voice coil: tightly wound small gauge wire of a large length (this is suspended inside a gap in the magnet).A “spider” which is a stiff but flexible material that suspends the voice coil assembly.Voice coil bobbin (tube where the coil is made).A metal basket in which the speaker parts are housed and a magnet is attached to.Standard speakers or subwoofers have the following parts: What is the difference in dual voice coil and single voice coil subwoofers? The difference lies in their design & how they’re used. They produce sound when a musical signal is supplied.ĭual voice coil (DVC) speakers, which are most often subwoofers, are almost the same as standard single voice coil speakers. They both use a small gauge wire tightly wound on a speaker “bobbin” (tube) that rests inside a magnet attached to the cone. 8 Ohm dual voice coil sub wiring diagramĭual voice coil speakers are extremely similar to single voice coil models except for having a 2nd voice coil winding, wire, and wire terminals.2 Ohm dual voice coil sub wiring diagram.4 Ohm dual voice coil sub wiring diagram.How to choose & match a dual voice coil subwoofer to your amp.Single vs dual voice coil subs: which is better?.Do dual voice coil speakers have performance differences?.What is the difference in dual voice coil and single voice coil subwoofers?.Failure Diagnosis (no output, no power LED, etc.First and Last Name with complete Shipping Address.Please call us during normal business hours at 1-80 (option #1) and be prepared with the following information: Use our RFTECH:Knowledge Base for troubleshooting assistance.
