No "Room Correction" Topic option. Why?

Mike at least you can admit that a sign of emotional intelligence:-)

I also have a 240 line split in two, easy and as the OP and others know easy to do and undo IF there is future desire to invest in a step down transformer.

finally since we are on the subject of science based truth vs dusty old narrow experience, there are sources of excellent and effective acoustic curtains- just search on that subject line w Escondido, CA. In use at many mastering labs, recording studios ( ours included ), Kennedy Center, etc.

pm me and I will walk you thru some low to no cost acoustical measurement tools to help you baseline and improve your room.
Me personally I would put down a layer of sorbothane/cork w glue, paying close attention to stud sill plate ( wrap it up ! ) and then an engineered hardwood and then tune w area rugs, Labrador is an excellent absorber.

best, cool post. 

Also, for those not wanting to wander randomly I suggest Acoustic Design and Noise Control Volume  1 acoustic design by Rettinger

i am on my second time thru.... I think n times might not be enough...

Mike and All,

Thank you for taking the time to educate me.
I think for now I will go with carpet. I added
more reflective surfaces with the 3 new 3x4 windows
and the store door. I also removed a full sized slider
and a 2nd door with 1/2 glass. I also goodwilled a
huge credenza that was probably something of a diffuser.

Mike-Looking thru your component list, can you tell me if
the room correction equipment was a truly worthwhile
move? My room is good with bass so I'm lucky.

Thank you.

I trust tomic’s taste and his listening skills. I think I’d trust him with my Yater Signature and I’ve never met the guy. 

I’ve never heard a system on a tile floor so I’d defer to carbone’s first paragraph.

when you use the term ’room correction equipment’ it’s unclear your intent. i view that term as some sort of DSP (digital signal processing) that adjusts your music to fit into the room acoustics. i don’t use that approach.

my room is about being designed to be acoustically friendly with it’s shape, surfaces and method of construction. so no messing with the signal path. i keep my signal path all analog. i do have analog adjustments for my bass towers to optimize bass performance in room.

to answer your question; yes for sure, i do think my efforts to optimize the music performance in my room by making the acoustical changes was worth while. part of those efforts is the balance between the carpet section for the floor, and the hardwood under the speaker end. i also filled in my windows with inserts. and these things are only briefly touching the surface of all the things i’ve done over my 16 years in the room.

all that said; i think the most important tool to find musical harmony in any room is a musical reference in your head that you are striving for. or; delegate that role to someone you trust. it’s all about the room meeting your expectations.

and......if you are not clear what you want.......drum roll please......then you have no business trying to build a dedicated room. how could you even know where you are going? find reproduced music that is doing what you want. get a solid memory of that, and then find that same type sound in your room. that is the proper way to judge results. listening. you might need to revisit that reference sound a couple of times to recalibrate your ears as time goes by as you are working toward that goal. everyone is different as to how easily they can retain their aural memory.

and be prepared for the fact that as you evolve in your hifi hobby time and listen more your tastes and expectations will likely change, and what you expect from your room will evolve with you. and you will be able to make adjustments as you go along.

measurements are useful for problem solving, but proof of concept is what you hear.
