With three pair, you are limited to either 6 or 12 ohms.. I honestly think that your receiver would run fine at 6ohms, so I would try that first..
12ohms is simply series wiring all 3 shakers together on each side of the amp.
6ohms is two shakers wired in parallel for a 2ohm load and then this wired in series to the remaining shaker for a (2+4) 6ohm load..
Calculating it is pretty easy.. Series you just add the numbers.. two 4ohms is 8ohms.. Parallel is (R1*R2)/(R1+R2)... For the same numbers, you just half it.. (4*4)/(4+4) = 16/8 = 2...... If you had an 8ohm load and a 4ohm load, it would be (8*4)/8+4) = 32/12 = 2.66ohms, almost as low as two 4ohm speakers..
As far as attaching the shakers, in recliners you don't have much option. I'd have to see under the chair to really think about it, but I bet you could fit a strip of 1/4" ply between the foam and springs.. I'm thinking about 4-5 springs running front to back.. If it's crisscrossed springs, never mind about that idea..
You could try screwing them with small screws to the front/back, or sides of the chair frame.. Something to get the vibration up through the back of the chair, as the butt only effect gets old after a while..
Maybe zip tie a piece of wood across several springs? Again, if the springs all ready criss-cross and touch each other anyway, disregard..
You are losing some vibration through the zip ties too. No matter how tight you get them, they will never be as tight as one screwed into something else.. The wood works well because the shaker can become fully coupled with it and then has a larger area to hit more of the springs.. Right now your 5" circle of power is only transferring it where ever a spring is touching it.. So together you might only have a 1" circle of coupled energy..
I am trying to understand this post but I can't. Not a very technical person, far from it actually its a miracle I got this DIY project done properly. I installed two shakers and it seemed unbalanced so I am getting another one.
But my issue now is, I am using Aura Bassshaker rated at 50w, 4ohm. My amp is a Dayton 100W at 4ohm. Currently running the pair via series connection, making it 8ohm each. It means each Shaker is using 50W, 50W and 8ohm correct?
Wha can I do with the third one when it arrived? How do I wire them and what kind of power is given to each?
As mentioned, I am electronically an idiot so, I don't want it to explode or anything. At the same time I want to get the optimum power I can channel to each of the shaker without compromising performance and safety using the given equipment.
I am also not clear on how this Ohm and Wattage works. If I connect all three in series, I will get 12ohm, which means Shaker 1 = 33W
Shaker 2 = 33W
Shaker 3 = 33W
Would that be best ? Any expert help is appreciated, a simple drawing on which connect to which would even be greater, just in case I don't understand, which chances are, I probably might not.
Sorry for the noob question.
Thanks in advance.
