  • MTM overnight sensation ohm load

    Is it possible to add a resistor in with the MTM overnight sensations to lower the ohm load to 6ohms?

    If so would this mess up the crossover/ balance?

    I have a 6ohm amp. Should I not even worry about 8ohm vs 6 ohm for output?

    Thank you.

        I figured as much; IMO any amp that can't handle a nominal 4 ohms is a design deficient in current output.
        An impedance matching device ( like an autotransformer ) could be used if necessary, certainly I would choose that over using dead resistance that wastes energy as it generates heat.

          Here is a sweep of my OS MTMs to give you an idea of the impedance:

          -impedance minima is ~3.7 Ohms @ 225Hz.

            While the other folks have answered the specific question, here are answers to your general questions.

            1. You can always add something to the crossover. It won't be simple to figure out the results without the simulator.
            2. You will definitely mess up the exisiting crossover. In effect you are saying that you can do better than the designer, which sort of begs the question: "why don't you design your own".
            3. You shouldn't worry about 8 ohm vs 6 ohm. If you look at RINNAV's sweep you can see that there really isn't a single value for speaker resistance.

            I was so much older then, I'm younger than that now.
