Qpower QHD112VL 12 in. Single Side Ported SPL Xtra Large Heavy Duty Empty Woofer Box

So I heard this box at a local retailer with Rockford Fosgate T-0 sub being pushed by 1000w RF amp, I was impressed to say the least. I know the T-0 is a very good sub, $300, it should be, but they wanted $200 for the box alone. I went out on a limb and purchased it here on VM for a third of there price and loaded a 12" DCV 2ohm Alpine Type-R into it. I am pushing this with an Audiopipe APCL-15001D amp at 1ohm and it absolutely pounds! Everybit as nice as the RF T-0 IMHO, this is a very good SPL box, it hits right in the 30-40hz range and has pretty good construction to it. Plenty of airspace, no flexing, and nice terminals for connecting your sub. No cons aside from its shear size and weight, being a single sub box, its pretty big. Thats expected though for SPL enclosures. Best bang for the buck on a budget.
