just wondering but is their any advantage of a Dual voice coil sub over a single voice coil sub.. other than wiring options? Guy at the audio shop was telling me something about distribution or some junk on how dual voice coil is better because the power was being distributed over both sides of the sub other than just in one spot. Was kinda hard to follow him. Anyways! curious as to what you guys thought. Other than wiring options I personally don't know any advantages of DVC set up.
He told you WHAT???????? Go back to the store and tell him to go to "speaker school".... This guy is complete idiot. he is making up crap or heard it from some buddy that heard it from a buddies second cousin removed, etc..... There is NO advantage of using one or the other. HOWEVER!!!!!!! The parameters can be different, so one may work better in a certain box than the other!! (same size/brand one dvc, one svc, old Orions were that way) Tell the salesman to come to MY HOUSE and tell me what he told you, i will set him straight!
Pedro..it all depends on the amp and sub combo But as for as which is better??? There is no difference. A single coil sub that is rated to handle 500 watts rms is no better or worse than a dual voice coil sub that is rated to handle 500 watts rms. Yeah Dave go tell that salesman that he is gay...simple as that lol!!!!
right i get what your saying,but if you have an amp that puts out more power into a lower impedance and you only want one sub thats where the the dual would be the better choice.right? now as far as sound quality.....i'm sure the diffrence is small. sorry i didnt think that would work.
BUT... say you have an amp that does 500 watts into 4 ohms and 900 into 2ohms.and you want one sub.wouldnt that one sub at 900 watts 2 ohms be better than a 4ohm sub at 500 watts. thats the point im trying to make.
Better??? Depends on how much bass you want....but the sound quality will be no different...atleast inpercievable.
Yeah i thought it sounded like.. what!? but i didn't wanna say anything as it was HIS shop lol. He was trying to sell me some MTX 7500's and I was like well what about these Type R subs here.. and he is like oh well the MTX subs are much louder and better SQ than the Type R subs. Though looking at the price he wanted for the MTX i can see why he wanted to sell those more. They were like 70 dollars per sub higher than the Type R. He also told me JBL comps sound like crap.. jeez.. But his memphis coaxials sounded better or so he says.
Most of the time, the BL, QTS, and senstivity will be different slightly. Dual just has the advantage of diffently wiring option thus making it more amp friendly.
Where the duals come in handy is if you have multiple subs and you need to connect them....You can actually get a wiring scheme to mix parallel and series....... Let's say you have 8 subs....each has DVC....Each voice coil is 4 ohm...You could series wire each voice coil and turn that speaker into the same as one 8 ohm sub....now you have 4 8 ohm subs on one side and 4 8 ohm subs on the other side.....You parallel one side together to give you a 2 ohm load, then the other side together to give you a 2 ohm load.....Get a big stereo amp and it will be running in 2 ohm stereo..... It basically gives you more options when running more subs off of one amp...as well as other wiring schemes.....but I would think if you picked two identical subs with one being SVC @ 2ohm and the other being DVC @ 4 ohm (wired parallel) you get the same results.....
