technically speaking DVC should be more powerful because it has 2 voice coil.. and thus more electricity pass through and more movement.
That said, u will need more power to drive it and depend on how u wire it, it can be harder to drive. Do NOT expect to get double the power or beating 2x SVC. technically speaking if u want more power... but don't want to have 2 woofers, DVC is the way to go... |

QUOTE(mnkh27 @ Oct 10 2007, 12:32 AM) Yea, more wiring options for your amplifier. In no way a DVC is better sounding, louder or more changgih than a SVC. DVC @ 1 ohm easier to drive or SVC @ 2ohm ? technical comparison 1 ohm is easier to drive than 2 ohm ? I don't think so.  Added on October 10, 2007, 12:37 amIt's also not true that a DVC is harder to drive than a SVC. Very much depends on the power handling and sensitivity ratings of the subwoofer. I've had and seen many SVCs that are harder to drive than DVCs. So, why DVC? ... Answer: Wiring options. I.e A dual 2 ohm voice coil subwoofer can be wired to 4 ohms or 1 ohm. A dual 4 ohm voice coil subwoofer can be wired to 8 ohms or 2 ohms. Say, you want to install 2 subwoofers or more. Using a couple of DVC subs is easier to configure to accommodate or squeeze the most of the amplifier. Cheerio.   Of course if u were to wire it 4 ohm it easier to drive at an expense that you will get lesser power. i have seen alot of cases where amp shutdown when it's wired at 1 ohm. some entry level amp doesn't even take 1 ohm. |

QUOTE(craziechild @ Oct 19 2007, 08:33 AM)  tell me more about it... i dun think DVC has anything to do with more power output either... a 12" 300W rms DVC 4+4 or 2+2 and a 12" 300w rms SVC sub are still a 300 W rms sub... nothing more... also for more power output... you change the amp and also upgrade the sub and also the box if needed... that would give more power and feel... read the sentence again... given 2 amps 1) 12" 4ohm DVC (wired at 2 ohm) 2) 12" 4ohm SVC which one will draw more power ? if your amp is capable of outputing 300w@4ohm and 600w@2ohm if you scope your amp, i'm sure you know the answer p/s: some ppl just see 300w being much superior than 600w... of course not the resistant... if they take that into account, it doesn't matter... and technically speaking... 600w does indeed look much more impressive than 300w...but down to the SPL and SQ it doesn't matter Added on October 30, 2007, 12:37 am QUOTE(mnkh27 @ Oct 18 2007, 12:27 AM) Hur??? bro definitely an amp which is capable of driving low amp which i am talking about, wat's the point of putting a 'not in the spec' amp, sure blow up lor   Why would someone run a sub @ 1 ohm or 2 ohm off an amplifier that minimum impedence for bridged mono is 4 ohm stable? Plain dumb. You'll need dedicated monoblock (that is 1ohm or 2ohm stable) or a purposed high-current amplifier for that purpose.But I can kind of guess where you're coming from. You're basically saying that an amplifier is less efficient and stressed at lower impedence. However, think about this... running loads not recommended in the specifications is a no-no in the first place. It damages your equipment or kills it. Very simple actually. RTFM. * RTFM = Read the F**king manual.   just an example http://www.lightningaudio.com/products/pro...en_US&p_status= Lightning Audio Strike Amplifiers : S4.1000.1D Rated Power 250 Watts x 1 @ 4-Ohms 500 Watts x 1 @ 2-Ohms 1000 Watts x 1 @ 1-Ohm This post has been edited by vincent_audio: Oct 30 2007, 12:37 AM |
