Question about using Components

[tsenfw 10+ year member]

Kind of fuzzy on the whole passive, active, component thing. Passive is just amping a set of components and tweeters and using passive crossovers right? Active is putting a sound processor/active crossover before the amp?

If I get these RSD-65cs:

Will that be enough from my mids and highs?

Also, what would I need to run those? Would a 2 channel amp be enough or do I need 4 channels?

I'm not really up on the whole active thing so I wont comment on that but you will need a 2 channel amp that does somewhere between 100 and 150rms watts for those speakers.

yes, like an IS2100 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I didn't see any pics of the is2100, but I didn't read all 4 or 5 pages either. You have any pics of it?? I was going to buy closer to a 150 watt amp for when I order my components but the one you have would work good too. Are they underrated or does it push about what it's rated for?

To answer your original question. Passive crossovers you just amp and they split the signal and pass it to the appropriate driver in the component set. Active crossovers, you have some type of processor that splits the frequencies and the components get a seperate signal from the amp. For example, some head-units you can go 3-way active. This means the HU will output a separate signal for the sub, mid, and tweeter.

With an active crossover, you can adjust the crossover points as you see fit. On passive crossovers, the crossover points are determined by the hardware and you cannot make many adjustments. I've seen some passive crossovers that allow a +/- 2 or 3 db to the tweeter, but that's about it.

If you go active, how do you know you will be able tune the system for a flat anechoic response?
