If i parallel or series two mids to give either a 2 or 8 ohm resistance, how will this effect the roll-off on the mid output on the passive crossover?
is it doable?
thanks
Yes, it is do able. It depends on the type of amplification unit you are useing, if it will power easier at 2 or 8 ohms, most likely your safest bet is to go for the 2 ohms even though it will run your amplification unit hotter it will produce a better sound than at a 8 ohm, BUT KEEP IN MIND this is a hypathetical situation where your amp is 2 ohm stable if it is not DO NOT attempt to parallel it for risks of damaging your amplifier or the rest of your system. Now if you are running them straight off from your Head Unit then your choice is alot easier series them puppies, because I dont know of many popular Head Units that can properly power multiple speakers at 2 ohms, not saying that it is not possible but unlikely.
A couple of points here. First, I disagree completely with the above statement of "it will produce a better sound" at 2 ohms VS 8 ohms. In general, this is wrong. Amplifiers operate with more noise, more distortion, worse damping, less headroom and more heat at lower resistance. In general, a 2-ohm load will sound 10 times worse than an 8 ohm load. Run higher impedence loads for better SQ.
Second, you cannot simply connect multiple speakers to a passive crossover network. If you change the impefdence load the crossover point changes. Dropping from 4 ohms to 2 ohms will double the crossover point (raise it from, say, 500 Hz to 1000 Hz) and conversely doubling the impedence to 8 ohms will halve the crossover point (dropping it from 500 Hz to 250 Hz.) If you are using passive crossovers (such as those that come with component sets) then you must use the same impedence speakers the crossover is designed for. Or, if you are designing a crossover, you must do so for the speaker impedence you intend to use.

Support the12volt.comthanks for the above advice.....thought thats what it was...it will be running off a 2hohm stable amp...
will look into three way passive
