Subwoofer for Vienna Acoustics Mozart Grand

You need to do some research. I suggest beginning with the DSpeaker processor which has the ability to make almost any sub work with your room and speakers.

In an in home comparison REL were a worst performer. Compared to the other subwoofers their connectivity and setup instructions were simply silly when I tried their Studio III.

["I have a friend who has a Velo DD12 in his install. It si an awesome sub and extremely impressive when it comes to a movie soundtrack. But when we spin an LP or CD, my friend says he prefers my REL."]

Since most systems and rooms are different the inclusion of any subwoofer can have dramatically different results. In my direct comparison using the Studio III, JL Audio F113, and the previous generation Velodyne DD-18, both the JL and the Velodyne clearly outperformed the Studio in ease of setup, output, and were far less detectable while in use.

On its own with only a crossover and gain control the Studio's short dedicated Nutrix cable made the room location, beyond a few short feet, recommended in the two short paragraphs of the REL installation instructions impossible in my room. Using the Velodyne software the audible shortcoming was able to be viewed visually. Using the REL's low level connections via the Velodyne the REL was far better integrated yet still not as undetectable as the other two. This could be a product of the subs down firing design, I'm not sure.

The idea the Velodyne is a subwoofer designed specifically for, "movie soundtrack," says to me little attention was paid to the extensive installation and optimization instructions. I would suggest your friend spend the time it takes [and depending, it can actually take quite a bit but the results are worth the effort] to use the Velodyne Manual Optimization program. I won't even get into the advantages of the remote control.

In the parameters of my direct comparison the common declaration by REL users that their products are musically superior is to me purely subjective. The others that participated in the comparison including the Studio's owner, all agreed the Velodyne and the JL were undetectable until turned off yet provided more low frequency gain.


As I said here in my earlier post most any subwoofer could benefit greatly from DSpeaker, home theater room correction, or other equalization components. I suspect the Studio / DSpeaker would be a favorable combination.
