Going from two DefTech 12" subs in my 4000 sqft room to the FV15HP was incredible. Not only was the bass deeper, more articulate, faster, etc...it creates earth shaking experiences. When my buddy and I first unboxed it and ran a quick Audyssey calibration and played the IMAX Hubble launch we both thought plaster from the walls and fixtures on the ceiling were going to come down on us! Although neither of us have been to a shuttle launch it felt real with the FV15HP, even only at -13db.
I've always liked Tron Legacy, thought the bass sounded very good even with my DefTechs, but the 15HP brought it to the realm of FUN! It also made Cloverfield scary, WotW disturbing, Monster's Inc surprising, and the Transformers trilogy impressive. It made old music sound new, and new music sound incredible. I dug up an old Telarc classic, Timewarp and discovered new life in its lower octaves.
PacRim has its problems, no ULF and mostly one note bass, but the 15HP brings out sofa thumping mid-bass punch. I love it! Exactly what I was looking for in a sub $1500 sub!
I've been kicking around replacing this or replacing that in my HT, but this has to be my best upgrade besides going FP.
I auditioned other subs from ML, REL and HSU and none of them gave me the chest thumps I was looking for. Granted other ID brands might, SVS was highly recommended, but Rythmik just has the right mix of ingredients to make what I am looking for. Great customer service, great prices, great specs, great reviews, and a great community. Confidence to buy sight unseen/bass unheard.
My fav config is 1 port, 14hz, high damping. Only problem is the occasional port noise. Unfortunately it takes you out of the moment when it happens. Every time it happens I think about going dual port, but ultimately I prefer the punch of One.
Nonetheless, I LOVE THIS SUB!
Thanks Rythmik, Brian and Enrico!
