There are two mids, 8ohms each connected in parallel to create a 4ohm load. They are dead and I want replace them with some mids I have. The problem is that these measure 3.6 ohms each, in parallel would give me a 1.8 ohm load. Will my M1.0t have a problem with this???

That would be a hard load for most amplifiers on the planet. Could you not wire them in series?

Will my M1.0t have a problem with this??? 8 ohm speakers usually measure about 6 ohm of resistance (as opposed to impedance). 4 ohm drivers usually measure about 3 ohm resistance. Are you sure your replacements are 8 ohm drivers? They measure as if they are 4. Two 4 ohm drivers in parallel would be a hard load, but not impossible for the 1.0.

Could you not wire them in series? Does using a series connection decrease output levels?? I am running a 2nd pair of speakers (infinity rs2.5)(simultaneously) which have the same mids and they are in parallel, which is the original design. If I switched those to series then the tweeters would over power them and so on. Is there a way to make a series/parallel connection using only two drivers??

There are so many issues at play here, not the least of which may be a sensitivity mis-match. Not trying to rain on your parade, but I want you to be happy with your changes. Good Luck! Chris

Chris More like a blizzard on my parade. I am a Bricklayer. I have no idea how to mod a crossover, if I could even get it out of the speaker without smashing it to bits. I can see myself with a hammer and chisel already. I can deal with a slight sensitivity mis-match, I am just worried about damage. I own a pair of Infinity rs2.5's which use the exact same divers I am speaking of, (infinity emims) there are two in parallel (original design) and they rock. Is this where the crossover comes into play. Is there a resistor to lighten the load or something like that, cause, again, it must be under 2ohms.?? I really don't want to go back to college

So it isn't just a problem with sensitivity but the frequency band that the drivers see will be different. This will cause the overall speaker response to deviate from the flat response you desire.

Not sure what the chances would be, but it'd be worth a shot. You will most likely not be pleased with just swapping those drivers. I don't claim to know much about the subject, but having built several pairs (15ish) sets of speakers, I have learned that there are many, many factors that go into the design and getting a sound that is tolerable, much less one you'd be happy with. Sorry for the blizzard, sir... just trying to avoid you heartaches down the road. Chris
