No, no time unfortunately.

Black? Acoustica can do their polyester HD batts in black as a special order (at least I thought they did)

Also, these guys can get black insulation - well at least they did, about 2 years ago when I phoned them.

There's no way I'm going to get it up on the wall without ruining it. Anyone got any suggestions of locally available alternatives ?

That black coating is awful ****. It comes off and gets on your hands, walls and clothes. You need metho to remove it from the walls. What gap size do you have between the baffle cut out and the speakers?

Spoke to Acoustica and they do black as a standard product. Thanks for the tip ! I should have it within a week.

Hi Jamie,

Not sure that's the same stuff. The fibreglass I've got has a very thin black fibreglass facing layer. It's like fibreglass fabric stuck to the surface of the batts. Must admit I feel like a complete idiot for not getting a sample before I ordered. We've used truckloads of similar stuff on projects overseas, and where I tripped up was assuming that the local stuff would be the same ... for some reason the facing seems greatly inferior to what I'm used to. It's incredibly thin and brittle.

The gaps between the speakers and baffle cutouts varies from about 10mm to 20mm. For this I bought a sheet of EVA foam and the time consuming part was cutting to the required thicknesses.

Cheers,

Cool, its good stuff - its what I used on my speaker baffles.

I use a reasonable quality bread knife to cut it - not an electrical on, just a Mundial

An electric one might work - really sharp and serrated

Hi Peter,

It sounds like you'll end up with something suitable. I think you originally got the same Bradford stuff I had a while back. The coating is very brittle and comes off very easily. If you get any moisture on your hands, they go black from handling it. I can't believe they make that product because I can't see what use it is. It just looks like the US black-coated fibreglass but instead it's rubbish and better off without the coating.

How does the Acoustica price compare to Bradford products, is it twice as much or comparable? I nearly bought their vibration damping product.

Cheers,
Jamie

Just one thing, Peter. Did Dennis specify a material for the baffle gasket? I've seen closed-cell foam weatherstripping specified before just for the gaps between the baffles and speaker cabinets.

The polyester is about 1.5x the price of the Bradford stuff.

I don't remember a detailed spec for this from Dennis and I never asked. I just grabbed a foam that looked the right thickness, density and compressibility.

How did you get around the building regulations for the windows requirements?

Did you already move in before starting the build?

I'm thinking about planning a HT in a new house but I kepe getting stuck at the windows.

The room has windows which were covered after inspection. It also has massive over capacity in the AC with an added fresh air intake.

Hi Peter,

It looks fantastic. Seeing the column on the door reminded me of those massive hinges on the entrance door. Were they used because you had the column going on the door, so you had clearance when you open the door? If so, great thinking ahead.

I had dinner with your Masking System manufacturer last week (while doing HAA Turbocal, Level I and II - great courses) and we were discussing the timing of your build because I need Chris to have a look at my masking system when he's in Sydney next. I also need to take my system apart to do my HAA Level II certification so I'm trying to time it all together. I know he's waiting on some Fidelio, but are you planning to be 'screened' in the next few weeks or so?

Also, next time you're in Melbourne, ask Chris to take you to (or at least tell you about) the dumpling place in Chinatown. The food is excellent (and ridiculously cheap - without added salmonella) but they don't like you hanging around afterwards!

That Rim fabric is very nice and comes in a lot of nice solid colours. If anyone wants a free swatch brochure, contact them at http://www.rimfabrics.com.au/trilogy-one.php (you'll have to register)

Cheers,
Jamie

Hi Jamie,

The wide butt hinges on the door were mainly to allow enough clearance for the 50mm thick acoustic panels I'm attaching to all the walls. The weight of the door also influenced the number and size of hinges. Adding the extra weight of the column was an unknown, but I'm keeping a close eye on it and so far all seems OK.

I have tried to avoid putting deadlines on myself, because I know I'll fail miserably !! But since you asked ... I expect to be ready for Chris around the end of October.

Interesting that you've done some HAA courses ... are you going into the business ?

Cheers,

Hi Peter,

I'm thinking of setting up a theatre calibration, consulting and programming business initially sort of part-time and then if I get busy I'd look at doing more fulltime. There's no one really in Sydney that does it. I already been doing this stuff for myself and family for free for years. My current job in IT for financial services pays me well but a/v and gadgets are my passion.

Cheers,
Jamie

I have four doors in all, so it's a lot of fiddling around. My latest plan is to make the panels full size, add two sets of cross members about 5mm apart where I need to split the panel and then cut the panel in two. This should give me better alignment than trying to make lots of individual panels. These joints will be sharped edged to make them less noticeable compared to the radius edges everywhere else.

First of all, very nice theater!

I'm sorry if you have already posted the information, but I would like to know about the fan noise of the Procella DA-2800 amps? Would you say they are loud or could they be placed close to the listening position and not be audible?

Very difficult question to answer as it's so subjective. One man's quiet amp is another's leaf blower ! They are certainly much quieter than my old Behringer 2500, but in my room with the very low background noise, I wouldn't want them out in the room with me.
