Seperate Speaker Amplification

taylor_h25 · 4th June 2008, 02:33 PM

I am looking at building an ipod speaker system (amp, crossovers, speakers all in one). I am looking at using an active crossover and separate amps for each speaker. Should the total wattage of the different ranges all be the same. That is for instance 100w tweeter, 100w woofer and 100w mid range. If not would it produce a different sound.

It much depends on the drivers you will use....

Tweeters are normally more sensitive (SPL) than the basses, so you don't need as much power to drive these.
If you look at the specs of the drivers, you will normally see that mids and tweeters can't handle the same power (Watts) as the basses (but they don't need to because they are more sensitive).

Just see to that the active crossover you use (or each amp) has a gain (Volume) control, so you can adjust power to each driver.

Rod Elliott has a good article on Bi-Amping, worth reading for what you plan to do...
