[QUOTE="thylantyr, post: 3044427, member: 560358"] I see this as two paths. The hard path - Electrical engineering The easy path - Variable crossover, common sense, listening test You can use your pencil, paper, calculator to figure out the technical aspect of crossover design factoring in tons of variables, this takes time. People are moving away from this methodology because there is speaker software on the market that does this, but you have to learn the software which takes time. Or You can build a loudspeaker using a flexible active crossover, apply some common sense when you make adjustments, do some listening tests using a test box and zero in on what settings gave you the best sound. Then you have choices. 1. Continue to use that 'development' processor in your system 2. Take those parameters and make a passive crossover equivalent. 3. Take those parameters and make a active crossover equivalent. Note, if you built an active crossover, if you choose your components well you could make your active crossover have variable frequency selection by using precision ganged pots instead of fixed resistors. Another method is to use fixed resistors to select crossover frequencies, but you can use sockets and headers to make resistor modules to change the frequency, you see this in car audio. Which path do you take? Depends on your goals. If you want to dazzle people with a crossover engineering marvel to show off, then make a technically correct design, but there is no guarantee that it offers better SQ. If you want to zero in on best SQ, then do the simple approach and don't worry about if it's technically perfect. All that matter is that you liked the sound. Or do a combination of both. For car audio because of the environment, the tweaking method is ideal. You want to be able to change variables. For home audio you don't have installation limitations so you can choose any method, but I still prefer the 'listening to the speaker' method and turning knobs to get the best sound. The simple method, IMO is superior because it tackles the root cause, what gives me the best perceived sound. But the simple method also assumes that you used good drivers and you executed a good loudspeaker recipe, nothing dumb. [/QUOTE]
