Advice on dedicated room

Hi everyone ,

I am going to start building my dedicated listening room in the basement soon and need some input. My ceiling is just under 8’ so would 2x4s be adequate for strength or would 2x6 be better? Second , I read an article where Robert Harley was building a new room and used the ISO wall system from acoustic sciences and was wondering if anyone here has used it and liked it. I will at the least use 2 layers of drywall and green glue. Lastly my space available is 15’x16 1/2’. I know that is too square and I can shorten the 15’ direction if needed but if we’re to put a 45 degree angle on two corners ( one corner is needed for access to another area) would that negate the “too square” aspect? Thanks for your input

Thanks for the first hand experience advice it is very helpful. I will add a system to my page when it’s all done. Ordered my speakers today !

I will probably be adjusting for a better ratio and the DBA is on my list too. I have Robert Harleys book and am reading it now in my limited spare time. I will go to the modes section and learn about it. It’s a fantastic book! Thanks for the advice.

I will probably just go the double drywall green glue route. I will add in wall sound proofing as well. My basement is unfinished so I have options on the direction I take. Thank you again everyone

@baylinor and @mickeyb 

Thank you for the advice. I’ve received a lot of great input from everyone.

Does the closed cell foam go between drywall and stud or in the space between the studs?

Thank you everyone for the great input. I will be looking to soundproof and treat when it’s all done. The ISO wall was touting the extra bass absorption their system has so I thought it might be worth trying. I know there will be in room treatments as well after the room is complete.

I have concrete on three sides with the two opposite concrete walls probably extending out an undetermined amount. I haven’t started anything yet so all options are open. I have a dedicated sub panel that serves the main floor home theatre that I will also use for the 2 channel room.

I consulted with one company that I believe was going to design Helmholtz in the room. I didn’t go with them because they said it would cost 50k when done. Far too much for me but I will still look into it. Thanks
