[QUOTE="squeak9798, post: 887830, member: 555320"] Ohh.....crossovers are [B]FAR[/B] from the same. Crossovers are honestly a pretty big topic to cover. There are many, many things to take into consideration, and many, many different crossover designs. Linkwitz Riley, Butterworth, Chebychev, Bessel, elliptical........And you have things to take into consideration like phase shifts, efficiency (higher slopes will give you greater efficiency), etc etc....... Basically, for the best "sound quality", you would want to use the crossovers that optimize the speakers and their in-car performance. You do this by way of selecting the proper crossover type, points, slopes, and "accessories" such as zobel networks. This is where the "active vs. passive" debate comes in. The passives that come with your pre-built components (like Boston Acoustics, Alpine, etc) are optimized for the speakers themselves; but they are not designed to optimize the speakers performance [I]in your car/install[/I]. The crossover points and slopes that "optimize" the speakers themselves will [B]not[/B] be the same crossover points and slopes that are optimal for your install. You may need to underlap or overlap crossover points, different slopes may be necessary, etc etc. This is where active comes into play. Active crossovers allow you to select what crossover points (and sometimes slopes) are used, so you can use the combination that works best in [B]your[/B] car and [B]your[/B] install. This can help you achieve better in-car response. Active crossovers also give you level control over both the mid and tweeter, whereas most passives only have volume controls on the tweeter. However, active crossovers don't allow for things like zobel networks, tweeter protection, etc etc. You [I]can[/I] build them yourself and add them in-line with the speaker though. Plus, the active crossover is another item in the signal chain, and the more things in the signal chain, the higher the chances of noise. So, basically, there is no "best", as with anything. You just need to find what works best in your car and your install. [/QUOTE]
