Help a newbie with a crossover for a mini-array pls!
Here are the drivers.
12 Aurasound NS3-194-8E
http://www.madisound.com/cgi-bin/index.cgi?cart_id=1338435.10501&pid=1757
and
12 DAYTON ND20FA-6 3
http://www.partsexpress.com/pe/pshowdetl.cfm?&Partnumber=275-030
crossed at 2700
Curt C mentioned that the neos can be crossed lower than 3500 hz if they are used in multiples and use
a higher order(4th
)xover.
The 12 auras will be wired in 4 parallel groups of 3. Yeilding a net sensitity of 97 db and final re 0f 5.2 ohms(accdng. to PCD)
The 12 dayton neos will be wired in 3 parallel groups of 4 drivers. Yeilding a net sensitity of 101.5 db and final re 0f 6.9 ohms(accdng. to PCD)
Baffle would be 6.5."
Of course these are based on the measurements from the websites. Being new to this I dont have measurement stuff to do my own...yet. But i am learning and trying to get my feet wet in this newly found hobby/obsession. Thats how
I learn the most.
Well anyways...so can anyone plss. help me with the crossovers by modeling one? Since I dont have any measurement abilities yet I dont think textbook crossovers are going to cut it. Yes I did build other peoples design and they are great. But not arrays...so a cost effective quasi mini-array(full of tradeoffs of course..the kits costs are not justifiable to the wife) is the way to go for me.
Help a budding diyer anyone? Sorry for the long post.
Do you also need BSC in a line array?
