Hi guys
Sorry I haven't finished the post yet, I've had computer issues
As mentioned in the last post the last thing to do with the room is to treat it. This is hopefully where I tap into some of the wisdom on the Kdac forum
I want to go fairly softly here as the room sound pretty good as is. For the rear of the room I have a large bookcase that is randomly stacked with various goodies at the top, with records and CDs down below. At the moment I am happy with this treatment for the rear wall.
For the front I am about to build some diffusor/absorbers from lightly curved ply with random holes drilled through it and filled behind with Polymax Absorb
http://www.polymaxinsulation.com.au/acoustic_specialised_projects.html which is non irritant and works well from 125hz to 4000hz. The upper frequencies will be partly diffused by the curved board and partly absorbed into the holes and polymax within. I can mount the pannels slightly off the wall. Dimensions are not yet fixed, but something like 500mm wide and 1000mm long. I am looking to build three of these to hang on the wall and play with positioning to see what sounds best. They will be covered in cloth of my wifes choice
They should look quite nice. I ordered polymax a few months! ago, but as its a small order I'm getting jerked around a bit.
As for the rest of the room, well I have glass down much of one side which I usually take care of with timber blinds, which work well. I like wood and natural products. I can also easily adjust the angle of the timber slats so they are all facing about 45 degrees from vertical, which I'm guessing acts as a diffusor to some degree. I can pull some heavy curtains across, but I don't want to kill off the natural ambience of the room. I am not that worried about side reflection points that much as my Goodman's are quite directional and I toe them in quite a bit.
Floor is covered in short carpet. I really wanted a nice hardwood floor, but it was out of our budget, maybe next time. I love the tone of wood!
The last thing to do is sort out the bass. Given it's a medium sized room there is only so much bass I can fit in
I do find the Goodman's set of a room mode on some material. Not measured it, but I certainly hear it. I did try lifting the speaker cabinets off the floor a little to reduce bass output. That certainly stoped the isues to a large degree, but it killed the magic as well. I really get moved when a system has a rich, coherent and weighty sound through the midbass. Raising the speakers reduced this effect so I dropped them down again. My wife does not want large ugly bass traps in the room (what wife does?). So the plan is to build some nice lamps (see pics) with the bass traps built into them. The idea here is to create a 300mm to 400mm thick block of Polymax that runs most of the way up the lamp, with the light in between sections. These can then be placed into the corners behind the speakers, which I am hoping will tackle the bass issue - won't know until I try
Love to know your thoughts
Cheers, Andy
