The software was not posted on the website as of Tuesday, so I contacted Velodyne by email and they sent it to me. Just uploaded it to the SMS-1 last night. I will run some bass demos and report back any changes / improvements. I would also be curious to hear of feedback from other SMS-1 owners. Presumambly, this is outside the normal audible range, but if the distortion and roll off problems were as high as reported on hometheatershack, you would think there would be some improvement with the fixes.
