Nothing on that page talks about running two separate amps to one sub.
Can I run 80 Hz to 120 Hz to one voice coil from one amp and run 75Hz and down form another amp to the second voice coil ?So, when we run two different signals to the voice coils, what we find is that the magnetic fields of the two
combine to generate a net TOTAL field that interacts with the static field of the magnets. The two voice
coils NEVER fight each other in a physical way; it's all in the magnetic field.
my bad, should have been more specific, two separate signals to one sub, which could be substituted as also one signal from one amp and one signal from another amp.
There's one thing that often comes up about wiring DVC subs, and that is the mistaken conclusion that
running different signals to each voice coil will "ruin" the driver. Let's recall how a dual voice coil driver is
built. Basically, a dual voice coil driver consists of two motors (the voice coils) co-axially mounted
Thanks PaulD,sure you CAN ... may not do much for you
I would say you can do anything you want, because as your mom used to say, "your special", might be short bus special, but none the less you are special!!!Can I run 80 Hz to 120 Hz to one voice coil from one amp and run 75Hz and down form another amp to the second voice coil ?
HmmmWhat happens when you run different signals into each voice coil of a dual voice coil speaker?
Essentially, if there is any difference between the signals driving each coil at any given point in time at a given frequency, the voice coils will either fight each other or help each other, depending on the phase relationship of the two signals at that frequency. This is not the same thing as bridging an amplifier and can create undesirable non-linearities and distortion because different input signals at each voice coil create shifts in the speakers electrical parameters.
For this reason, it is advisable to mono-bridge the amplifier whenever possible and connect the voice coils of the dual voice coil speaker together in parallel or series. If a dual voice coil subwoofer must be wired to two independent channels, the inputs to both channels should ideally be the same (summed mono) and every effort should be made to match the gains of both channels as closely as possible.
But . . . do U want to find out , that towing a boat with a 4 cylinder car can be done - once or twice before you need a new transmission ?I don't see anything that states damage will occur, only that it's not optimal.
My thoughts on what you posted.
It's interesting to me that you used an analogy that's directly related to a components ability to dissipate heat. The engine that's in front of the transmission is only one variable, a small one at that, that will dictate the life span of the transmission. In fact an eight cylinder with more available torque and a heavy foot will overheat the transmission faster than the four cylinder would. I could go on, but that's not what this topic is about.But . . . do U want to find out , that towing a boat with a 4 cylinder car can be done - once or twice before you need a new transmission ?
I mean if U do . then GO FOR IT !
Maybe I've missed something.so it seems that few people actually read that article, some looked at it but didnt read it.
has anyone actually tried this? im curious to see what the difference would be. how it would actually degrade the life of the speaker.
@oliver- yes you are golden because i said so, thanks for the shout out!
How would this cause damage to the amplifier?cobra93,
Is it worth the price of an amplifier and subwoofer to try it ?
I've seen guys try to use one coil on a DVC sub [ 3 dB less output when you use half the available motor, wrong box as parameters change ], can it be done ... sure !
would you want too ?
