Hey guys, I just purchased an Ashly XR 1001 unit with the intention of using it in a 3-way mono old school setup trying to get back the sound I had back in the 80s. I have used analog xovers in the past but to be quite honest, I would simply set everything to where it sounded good to me and that was that but now I would like to understand the basics if you guys can help me with this please? First let's start with the other equipment I will be connecting to this oxer? My rack is full so I am intending on using 2 Crown 3600's, one for bass and the other, one channel for mids and the other channel for highs. My Stanton RM80 Mixer will connect to the xover. The speakers are Sonic Dual 18 subs: Sonic R218 Sub and the old school Peaveys SP2: (Dead Link Removed) I have attached a screenshot of the 3-way mono setup taken from the guide. First step is setting the low frequency, since the sub's info is 40 - 7khz, 102 db 1w/1m, I am thinking to run this sub somewhere between 40-100hz? What's the best frequency Range setting for this and also which setting is best for the "Response" setting and why please so I can understand it"?
