Big sub-woofer sitting on carpet HELP

I have a Velodyne also, and I added four screw in audio points which definitely improved its sound over the four little rubber feet that are attached by one small nail each. This was done in my dedicated sound room located in my basement, concrete floor, carpeted. I purchased the mega points used on Audiogon and have four extra, email me if you're interested. I can't recall the name brand at the moment however if you are interested I could check when I get home.

I had a big Velodyne and had problems with boomyness and intergration. Under the advice of my local hifi store I put it on a six inch stand. WOW! What a difference. It cleaned up the sound and made it blend a lot better. I put it on a box but if you like the sound there are small stands out there that also look good.

What have I been smoking? This piece does have 4 tiny feet on it. I never noticed them till I flipped the amp up to have a look. Hmmm what to do now? I'm not saying I'm not happy. I just wonder if I could be happier:~)

I have the same woofer and I had an unfortunate accident with some brass spikes that I installed. Or may it was the 40 lbs. of lead shot that I laid inside the cabinet. Anywise, I drilled the bottom of the cabinet and screwed in some inserts and then screwed in the cone spikes. One day I was positioning and I didn't lift enough and it ripped one of the spikes out with a chunk of the bottom. As I looked at the material that they used to make the cabinet it resembles crunched up cardboard. It is probably great for sound deadening but terrible for supporting spikes and 110 lbs. of speaker. I repaired the damage with marine resin and bought a set of three huge Maple Shade spikes that have three small spikes on top. They have worked fantastic and I highly recommend them. But bypass the drill and inserting of threaded spikes. Dale

Hello Glen!
I have a Sunfire sub that I have welded a "cradle" for with 4 spiked feet to penetrate the carpet with. I also added another small home made wooden box with 40 lbs of lead shot sealed inside to sit on top of the sub. The combination of the 2 has done wonders for my otherwise not-so-musical sounding home theatre system. It tightens up the bass and makes the sub integrate far better with my other speakers.
The best $30 I ever spent on audio by a long shot!
