Summary: I recently replaced my 14 year old Velodyne FSR-12 with the DD-15. I did so because the FSR-12 was struggling in our new house with larger great room, and because the DD-15 was on sale due to its being replaced soon by the DD-15 Plus (at considerably higher price). The DD-15 is cruising in our new house. It really provides the bottom end that my Klipsch Heresies cannot. And it does not run out of steam at high volume, like the FSR-12 did.
Summary: I bought my DD-15 about 6 months ago after many experiences with my brother's Velodyne HGS-12 and being simply amazed. I have it in a room which is about 12'x30', and it adds a whole new dimention to any movie or music that you play. The bass is tight, and deep, and when you push this thing, you'll have to put those little felt pads on the back of the pictures hanging on the wall because they WILL shake.
Summary: First off, I'm not a audiophile, so you won't see me talking about techno calibration statistics, but I do enjoy a quality sound. As such this subwoofer can go extremely loud and low. You get what you pay for. This is an extreme performer but comes with a hefty price, you need to decide if that quality is worth the price.
Summary: The Velodyne DD-15 uses the same size magnet the 18" does, without nearly as much expense. The sub did a great job blending in with my large Klipsch speakers and is fantastic at reproducing low and mid range sounds. The system includes an easy to use set-up - that maximizes the impact of the bass. Made my system sound 50% better - replacing a Klipsch sub with 2 12" speakers - incredible difference.
Summary: Bought my goes unheard in early March and have not regretted it one second since! Absolutely incredible subwoofer! Room calibration / equalizer works very well! Köpte min olyssnad i början av mars och har inte ångrat mig en sekund sedan dess! Helt otrolig subwoofer! Rums kalibrering / equalizern fungerar mycket bra!
