I got the go ahead from my wife to build a pair of line arrays for the bedroom! These will only be used for low volume music listening.
I have a few cases of the Parts Express NSBs that I picked up for $0.49 each. What I was going to do was build two thin lines with 20 of the NSBs in each, standing roughly 84" tall. The enclosures will be ~2 ft3 each, sealed, with a moderate amount of fill. Unibox shows f3 at 113 hz. and f10 at 75 hz.
I know above 3khz there are going to be comb lines beginning to form so I was wondering if you guys feel an active EQ will be able to mitigate the cancellations? Take into consideration I'll only have $20 in drivers and probably another $30 in wood and supplies so I'd like to keep the EQ price cheap. Any suggestions on what type to get? I'm thinking I'll need at least 15 bands but those start to get pricey. I've seen some stereo 10 bands go for next to nothing ($20 for an Audiosource on ebay two days ago). Also, with EQs like this I take it they're simple parametric? Any idea what Q they are set at? I do have a Feedback Destroyer that I never used due to picking up a DEQ2496 for my IB sub and was curious if that could do the trick as well?
Lastly, do you guys think I could get away with 1/2" MDF for a project like this? I was thinking 7W x 8D x 84H with either 4 or 5 different sealed chambers. That would be 50% less MDF dust in my garage along with more breathing room for the rear of the drivers.
Thanks!
