i have polk momo 10inch in a sealed box as per polk recommendation
about .66 cu ft i think, around 15x13x9 outsides
the quality is nice, but im missing the lower freqs,
i ran a freq sweep, in car, i have cont drop from 50hz below
i was thinkin of using ported box, tune at 45hz, the polk site says i would get abt 10more dbs in 40-60hz range, which isnt a bad thing :D
but what abt quality? how much does that suffer? i dont want loud, but clean low base.
im runnin it off 150 rms amp
will be upgrading to 300+ one, but wt first? amp of ported box??
