[QUOTE="keep_hope_alive, post: 8653887, member: 576029"] To expand on crossover discussions, the slope (topology) of the crossover you use will also determine the desired crossover point. You can easily build your own crossovers with parts available from Parts Express. The cheapest is a single in-line component for a 6dB/oct slope: single capacitor for high-pass and single inductor for low-pass. Increasing the slope to 12dB/oct, 18dB/oct, 24dB/oct, etc. adds another component each time (which adds cost, complexity, and physical size). Because a 6dB/oct slope is pretty shallow, you may want an even higher speaker crossover point (such as 100Hz since the speaker will only be 6dB down at 50Hz). Likewise, a 60Hz LPF at 6dB/oct means the sub will only be 6dB down at 120Hz. You'll find that you will want a 12dB/oct slope, most likely. Parts Express also has charts for what values of capacitor or inductor for each slope and point. [/QUOTE]
