[QUOTE="thylantyr, post: 2114621, member: 560358"] 1. Don't mess with NSB dust caps. 2. Try to make the ports swappabled to allow different tuning. [60hz - 100hz range]. 3. Best NSB SQ = 4-6 coats of lacquer on the paper cone & dust cap, not surround. 4. NSB frame lip sucks, it hinders proper NSB installation in the hole for an air tight fit. Do some test cuts on scrap wood to analyze perfect fit. Use rope caulk as the gasket material between NSB and wood. 5. Minimize internal chamber echo with good sound conditioning polyfil, but don't hinder port operation - keep the poly near the walls and leave the air space more open. 6. High pass the NSB to minimize cone excursion. Try 80hz - 100hz with 2nd order - 4th order crossover. I cross mine at 65hz, 8th order as it works fine. This boosts your power handing - or run no high pass but keep volumes much lower. Did you come to a conclusion on wiring? [/QUOTE]
