Pulled the trigger on a Velodyne SMS-1.

Well over the passed month or so I have been looking to upgrade my receiver but ended up going with the Velodyne SMS-1 subwoofer eq. Over the weekend I was able to spend some time with some good friends I used to work with and trust one of which use to work at Dolby. We discussed my situation and they both felt an independent sub eq would yield the biggest upgrade in sound to my system. Along with some room treatments I have planned. While I knew this already there was something very appealing about a new receiver. I think you guys know what I mean. :D I figured the upgraded Audyssey MultEQ or XT would do the trick with my sub.

They pointed out that while Audyssey is an impressive system it will not smooth out and eq my sub the way an independent eq would. Which is one of the main reasons I was looking to upgrade. I would have liked the other goodies with the new receiver but I think they are correct. The power increase would not have been noticeable since my speakers are already pretty efficient and don't need much power to get loud enough in my current room. The only upsides would have been the video processing to upconvert the Wii picture and the more advanced Audyssey which would help but not like a good sub eq would. Since I was able to get the SMS-1 for 429.00 I decided to go this route and wait a little longer for a new receiver.

So if anyone has any good info on the SMS-1 please feel free to share. I'm excited to hear well eq'd bass with my HSU STF-2. :D

Behringer BFD?

I'm curious whether you compared it to the Room Equalization Wizard (REW) + a Behringer BFD? Does it do anything a BFD doesn't?

yes :D save you a million hours of learning the REW and BFD.

aside from that, it's got a built in mic, on screen graph and good interface.

I'm a lazy SOB so I always take the path of least resistance.:D I have no interest in learning the BFD/REW solution. To much work.

I use this myself.

At the time, the SMS was too much dough, and for my fairly uncomplicated room, RW and Behringer more trouble than I wanted to bother with.
Although, I did do a check out with this disk.

There are comparisons on www.hometheatershack.com between devices, including probably the most comprehensive analysis on the methodology.

The 8033 is a breeze to set up even for multi-subs.

Just another option.

Well my SMS-1 is now set up. However I'm not blown away. My room response was not horrible to begin with. I had a peak at 48hz which I was able to get rid of. However I have a noticeable dip at 63hz which I helped a bit by boosting this frequency 3db. Which is the max I will go since boosting frequencies is not the best way to get rid of dips. I also have a similar issue around 80hz but not quite as bad. I boosted this 3db as well. Switching polarity and adjusting phase only mad things worse. I would say I'm down 3 to 5 db's in this range.

Outside of the peak at 48hz and dip at 63hz I'm pretty flat down to 25hz which is where the HSU STF-2 rolls off.

I have limited placement options to work with except one other spot which I will try in the coming days to see if there is an improvement.

Audyssey 2eq changed the distance on my sub from 10ft to 14ft. Which is probably due to the SMS-1 being in place now.

So overall not bad. But I'm wondering how well Audyssey MultEQ would have handled things since the response is not that bad to begin with.

When I switch out the EQ during certain bass sequences I notice a subtle improvement but nothing night and day.

One question I do have is. What sound mode should I be using on the receiver when the tests are being run. I had mine set to DPL II. The manual made no mention of this so I thought I would ask.

i think mine was set to stereo mode when running the sweeps ... but i doubt it would make much difference :)
