Bronze Member Username: PolksavagePost Number: 28 Registered: Jun-06 | yes I've heard both but I've found out the lsi are 4 ohm so I'll have to get a different receiver so that kills that idea |

Silver Member Username: PraetorianCanada Post Number: 247 Registered: Dec-05 | Depending on your receiver, you can set the x-over to variable freqs. Also, the extreme end of ea drivers range can distort at higher volumes and peaks (i.e. explosions), so, for example, the RTi 10s I own have a range of 40 Hz to 27 KHz, my sub has a range of 25hz - 120hz. Some receivers have default x-overs (usually 80 or 100hz) further some subs allow you to set the low-pass x-over. If I were to go by the specs I could technically set my receivers x-over to 40, and the roll-off on my sub to the same, BUT, since my subs 12 in driver sounds better at the lower ranges than my 10s' 7 in woofer, I choose to spread the work out between the two of them and have my x-over and roll off set to 100hz. This is what I mean by spreading the work around, instead of having my mains work to their extreme low range, I pass it off at an easier freq for them to respond to. Clear as mud? |
