Concrete block stands for my Quartets

Howdy folks,

I've been thinking about some type of heavy duty stands to raise my Klipsch Quartets up a bit and allow me to take off the risers which I don't really care for. The holidays have given me some time off and a chance to work on that project. I was originally going to make some stands out of a combination of red oak and mdf but it involved a fair number of cuts so I had been saving up for table saw. While I was at Lowes pricing saws I decided to go outside and look at pavers to put in front of my shed and I came across these beefy blocks that I think are used for retaining walls in landscape projects. The first thing I noticed was they are very close in length and width to my Quartet's footprint and it gave me a creative flash. I liked the rough face and thought they'd make very solid stands so I bought four of them (and four more the next day) and a can of satin chocolate brown Rustoleum. These things are very heavy at 46.6 pounds each. They have a channel roughly three inches wide and half inch deep formed in the bottom which I am not sure what it's for but they still stacked well and are very solid.

After taking the risers off I cut some small gel pieces out of insole pads for the four corners to protect the bottom of the speakers. Then I tried a couple of the blocks and they were a nice fit but I realized I'd need about four to really get the speakers high enough to hear the difference. My Quartets are now sitting on about 185 pounds of concrete so these stands are definitely mass loaded. Being dark brown, they looked fine on my tan carpet (which is coming out this summer) but I thought an oak plank under the block would be a nice finishing touch so I glued some boards together and stained the edges to roughly match the speakers. I like how they turned out.

I also finally got around to boring a hole in the back of my credenza so I could put my HRT Music Streamer II+ dac and SMSL SA-36a Pro amp in the cabinet. They had been cluttering up the top. I got lucky finding this very heavy oak veneered credenza for $60. The couple who had it was moving and wanted it gone. The amber/wheat color matches my Quartets very well. I need to repaint and change some pictures but things are coming together finally.

This pics shows how nice the curly oak veneer is on these Quartets. I've seen a lot of oak Klipsch speakers but this is the only pair I have seen like this. With oiling, they have taken on an amber tone that I find a lot nicer to my eye than the usual light oak. I also had bronze glass tops cut for these when I got them.

My back hurts a bit and I smashed a finger putting these heavy blocks in my truck but overall, I'm happy with how this turned out. It can be challenging trying to come up with heavy duty stands for larger speakers. For me, they have to be functional, look like a good match for both the speaker and the setting, and hopefully cost less than $100. Now, I'd like to pick up another set of grill frames and use a nice brown speaker grill cloth :thmbsp:.

one last thing....Happy New Year!

The stands turned out great. Actually the whole system looks great and a very clean and uncluttered installation !!!!

Thanks guys. I appreciate the feedback. It was a fun project. The stack nature of the stands does allow me to move them myself if I ever need to even though they are so heavy. I found aligning them was much easier when I put some strips of packing tape on top of each block. I'd just bump them with the palm of my hand until they were perfect. They scrape and drag against each other if you don't use anything. I just picked up an extra set of grills on ebay to try an earth tone fabric color. I didn't want to sacrifice these grills since they are perfect. I was going to use dark brown to match the stands but I am still looking at other options.

I wrapped cinder blocks in brown towels once in a pinch to use a pair of bookshelves in my main rig, but it sure didn't look as nice as that. Great idea and execution, nice room too.
 
Wow! They came out nice. Way better than my usual Kitty Litter container full of rocks approach! I ilke the veneer on yours. Mine have normal type oak and yours are nicer for sure.
 
after being a bricklayer for the last 40 yrs ive been doing this from day one.Currently I have my old Braun studio monitors up on giant red/brown bricks and they provide a solid support that can be increased in 4 inch incements higher or lower depending on your "sweet spot" comparitive to your usual seating area.They have always worked great and look awesome as well,,highly recommended

I have a buddy who is a brick layer too. He made a great looking mailbox enclosure for a neighbor and likes to get creative. This is my first block laying project but it went well enough that it likely won't be my last :thmbsp:.
 
Looks nice! Hope you got good floor structure there ... LOT of weight!

FYI ... That ridge on the blocks is there to allow an easy offset distance when building a retaining wall. Just set them and push them all even with no measuring required.

Another neat trick if you don't need the height is horse stall mats. A 4x6 foot section weighs around a hundred pounds so you get real good damping with a small footprint. Easily cut with a jig saw, and you can even use a router to round the edges if you so desire.

Stuff's only 3/4 inch thick, so it might be handy if you need to fine tune the height of your stack or just dress it up some, or for anyone who has taller speakers that could use a bit of damping. Do any machining outside as it smells like the backside of a dead goat when you're cutting the stuff. I imagine the SO would be a bit miffed to come home and find the house smelling like a tire fire ...
 
Thanks for the tips, skizo. The blocks and speakers combined weigh about 240# each which is about what I weigh. The total load is pretty spread out....much more so than the 75 gal fish tank I had where the credenza is now. That wall has the block foundation and footer for the west side of the house under it. There is also a support beam on top of concrete columns that runs down the center of the house which the speaker in the first pic is almost right on top of. I should be fine but I appreciate the concern and it is something which people should be aware of.

Good to take care of the details. Oft overlooked is what's going on under the floor.

My system weighs in at around 800 pounds across about 8 foot of floor - I ended up doubling the joists and adding a couple knee walls in the basement. Doubles as a nice little workbench too, so no wasted space.
 
I use heavy concrete blocks all the time as stands. I wrap them in black felt usually. Sometimes I even stuff them with high density fiberglass before wrapping them up.
 
Mark, how tall are those blocks? And roughly how much did they cost each? Thinking whether these would work with my Fortes, which are about 4" taller, so maybe I'd just need 3 per side.

They are 3" tall, 16" wide and 11.5" deep. I think they would work great with Fortes too. I had a pair and sold them which I later regretted. The blocks were only about $4.00 each I think :thmbsp:.
 
Looks great! Did you notice any changes in the sound?

Just the usual benefits that come from getting the tweeters and mids up to seated ear level....which was my main reason for doing it. I listened to Steely Dan's Two Against Nature album when I got done and the dynamics and bass punch were still very present. It did make the speakers seem much larger than they are.
 
You want to make speakers seem larger ... I just added a couple Aura Pro Shakers to the lazyboy here ...

Driving them with a 200 watt mono plate amp ... holy crap, batman!! Had it about halfway up on first fire, and had to chase the chair around the house for a while before I could turn it down. I'm thinking 100 watts would have been MORE than enough, as I get a good effect with this one just barely cracked open.

I expected it to be more of a toy than anything else, but used with moderation, the setup certainly does add ... IMPACT. Crank it up some, and you get a killer massage ... <G>

PS ... I can also get the same shake out of just my McIntosh XR16s, but we're talking dangerous SPL levels to make that happen. Which is also fun. ;-}
