Summary: I am an owner of Velodyne subwoofer like SC10 , Sc12 , impact 12 , and the subwoofers without a good crossover do not worth the money you are spending . This SMS-1 is a excellent product because you can precise select the correct crossover to your woofer or Subwoofer . For music the need of a fast sub in 160 HZ is very important depending of course the size of midbass you are using .
Summary: 4 stars only because GUI is antiquated...works as described remote and everything. If you have a highend system that does not use any other kind of correction, this is the product for you. I am using a Bryston set up with a Velodyne sub (older model). This unit worked great....I could see the changes in the frequency response on the TV as the AUTO program worked its magic. System sounds amazing.
Summary: I am finalizing my home theater build, and my room has 4 sub woofers. As many HT/Audio enthusiasts know (ie you... why else would you be looking at a $500 bass correction), multiple subs help provide smoother bass response throughout multiple seats in an HT. Unfortunately, controlling 4 subs seems like a daunting task. You can imagine my excitement when I was referred to the SMS-1: automatic bass correction for up to 3 subs.
Summary: This is a terrific product. I am using this as a crossover to remove 80hz and below from my bookshelf speakers and to boost the bass signal that is sent to my subwoofer. I am using the SMS-1 in-between my preamp and power amp. Removing the low bass allows my bookshelf speakers to better reproduce midrange and allows them to throw a larger soundstage.
Summary: These 5 star reviews are right on the money. The equipment helps you patch holes in your listening space. It is a bit tedious to configure but it is well worth it. I contemplated buying this because most amps come with Audessey which also manages bass. However, the SMS makes Audessey look like a toy. I let Audessey tune the bass first and listened to it for a day before pulling out the big gun SMS. The bass is noticeably more crisp and deep and even about the room.
Summary: I was hesitant to purchase this unit because it is rather expensive, but at least Amazon's price reflected a nice discount so I decided to take the plunge. I am glad I did - this unit really did improve the response from my subwoofer and what I have now is noticeably cleaner and tighter bass.
Summary: The SMS system has improved bass response in my room to near perfection. The ability to see the bass response on your display lets you find the best location for your sub woofer quick and simple. The auto set up feature goes above and beyond the limitation of most receivers since they often only correct a couple of points in the lower bass frequencies. Things get more interesting when you choose manual setup as it allows you to fine tune your bass response.
Summary: Simple if your sub doesn't have any sort of bass management you need this. The on screen display is decent being able to have presets on the remote is awesome. I am running this on some jl audio phantom 113 and they have a base managemet system in them but this one is so much better I use this. I highly recomend this.
