Help with riser construction.

[robk_11]

Hey guys, I was wondering if someone could give me some help with building a sturdy riser. I have a sofa and love seat that I moved down to my under construction basement HT. The wife argues against it (of course), but I would like to put the loveseat on a riser behind the sofa. She would rather have the loveseat Blocking the front right speaker :raped: . It is a never ending struggle... I know it is just building a box, but can anyone give me some material recommendations to make the thing sturdy enough to hold some poundage!

thanks as always,

Rob

Rob,

I built my riser using the concept by Auralex for a tactile riser. I basically used 2x10's on edge and used manufactured decking material from Lowes for the front and back of the riser. Decked it in 3/4 inch OSB. Since my theater seats are curved I built the riser with a curve to match. Only change I might have made is 2x12's instead of 2x10's. I also added side access steps at about 6 inches for the step up.

Per the info on the riser I used insulation bats to fill in between the 2/10's to about 1/2 the height. Also calls for 4" holes cut into the front face of the riser for bass response.

Decoupled from floor with 5/8" radiator hose (4 2" pices under each 2x10).

You can see basic layout under Chuck's Home Theater post.

I do not have my equipment up and running so I am unable to confirm if it will have a tactile response. If it need more motion I will add buttkikers to my theater seating.

It is about 7 feet deep to allow for the chairs to recline. If you are not using reliners the riser can be smaller.

Tell the wife the riser is for the premium seating and since its the love seat position its just for you and her. She will buy that hook, line and sinker.

I would agree with the construction above except for the radiator hose. Over time, it will crush and get hard. Use something like a stud isolator that is specifically designed for that kind of weight load, constant pressure, etc.

Good luck with the battle

I also agree with not using the radiator hose ....I'm in the process of adding a buttkicker and been looking for something to isolate my seats; I have decided to get the isolators recommended by the company.

I saw them on www.av-outlet.com set of 4 for a chair/sofa is $9.99 and for a platform is $15.00 a piece, you need at least one for each corner.

Good thinking about adding this isolators now ... not like me, that I didn't plan ahead

Good luck with your wife, I'm sure she will be Happy after you build the riser

I will save you some time reserching prices (I can't say anything about them because I have not installed it, hopefully I will get mine this weekend, but I read good things about it )
Best price is from one of the sponsor here Ultimate Home Entertainment (www.rtheaters.com), there is a lot of companies selling them and the price starts from $389.99 and up, but I can tell you that if you get it from Ultimate it will less than that.

Here is my riser construction with 4 Buttkickers built in. I love the way it turned out.

Nice work !!!! ..... Did you use any rubber isolator to separate the riser from the floor??? ...I was looking at the photos but couldn't find them.

Did you had a hard time calibrating them??? ... What settings are you using (high crossover on or off, What is the cut off limit you're using??, volume )???? ... I want to experiment with mine .... Right now I have the low filter off, high filter on and crossover at 80Mhz ... volume is only one third and shakes all the room ......
