So I�ve been building more of sq system, not a super high end one but a great one nonetheless. So I have a nice 3 way front stage and a set of coax NVX x6.5� in the rear doors. I loved how well those are doing so as I was looking at shallow subs (very new to me) I didn�t want to spend a ton. Being as though I�ve never had a shallow sub I figured I would start by building a 1.1 cf. box tuned to 34hz and then looked for subs under the $200 point. I found one of these as opened box for like $60! First off I had a 10� full sized sub before this now it wasn�t something that was 1500-2000 watt spl subs it was a P3 in a 1.25cf at 30hz with around 500-600 watts. It sounded great just couldn�t manage the box size in my car the way I wanted. My box now is only 5� deep so I�m able to hide it under my false floor. This NVX is putting out some amazing lows and very clean at that. Everyone who has gotten in A) doesn�t think it�s a 10� and B) nobody believes it�s shallow at that. It really sounds like a mid range full sized sub and I can�t explain how happy I am with this sub! If you�re in need of something shallow whether it�s a 10 or 12 don�t feel like you need to spend $400-$500 on a JL or other overpriced product. These will 1000000% not disappoint!
