Wow looks awesome, a massive attention to detail. I am just heading into a build in the next six months so trying to translate all of the American info and products into things that can be sourced locally. You mentioned you used isolation collars on the dyna bolts, just wondering where you sourced those from?
Thanks,
Michael

G'day Michael,

Thanks! I got those from Embelton. Their website seems to be down at present, but here is one link:

http://www.embelton.com/products/mechanical-isolation-mountings/

The pad I used is called Shearflex. If you order it (phone them) ask them about the collars.....do I think they'll help? probably not, but hey they didn't cost that much

Okky doke. Many thanks to Shawn at the Erskine Group for his work, I am extremely happy with what they have provided and the service. Highly recommended. Shawn did say it was the smallest room he's ever done!....erh, probably don't want to boast about that. That funny curve on the ceiling is an RPG waveform, I've always wanted one since first seeing a the little room they advertise it with.

Here is a bit of an idea:









Progress has slowed recently as we had two weeks away, I hope the US readers are enjoying the cold, we where here:



I am still slogging away at the HVAC, but when that is done I can get on to cables, insulation and then the ply/drywall

The speakers Shawn has recommended was the P6 Procella and Triad rears, which is fair enough. But I am going to go DIY.....its on me if it goes wrong!

The LCR's will be a 3 way with Acoustic Elegance mids/woofer and a Mundorf AMT.

The rears will be a DIY (hopefully switchable di-pole/bi-pole), with AE 8" mids and probably a Transducer Labs Tweeter - other option is a small BMS CD in a 8" waveguide....still playing around with that.

The subs - 5 in total. Two up front will be 15" AE TDH+ with 2x PR's each and the smaller ones will be just sealed TD15H+. The reason for these drivers is due to the limited depth I have to play with. If low end e.g. 16-30hz isn't enough I'll look at adding in something else (probably behind the L and R)

Is there a particular reason the surrounds and rears are up high compared to the listener? I assume the different panel patterns refer to different styles of absorption or defraction products? Looks like a great use of space, like the extra subwoofers to help smooth the bass all out

Hi Peter,

Plans look great and looks like a decent compromise on the seating to get the 2 rows fit in. I'll be doing something very similiar in that the front row will recline but I won't have the depth in the room to let the second row recline as well.

Do they provide measurements for the top and side views? I noticed there are dimensions on the screen but not the rest of the plans. I get that with a scale included one could work out the dimensions but to me it would make more sense to just show them on the plan for easy reference!

Sounds like getting the HVAC finished will be a major hurdle cleared, it should fly after that. I've sent specs out on mine to a number of 'air con' companies in the area for design/quotes ... got a few bites but the exacting specs might be sending some running for the hills!

To do with the limited width of the room I believe, same with the use of dipoles as oppose to monos you would see in their larger rooms

Yep, I had to really press for the second row, its not at all ideal......gave Shawn some real headaches from what I gather

The plans above are for posting online, I've got fully dimensioned/more detail in my ones for the build.
chrapladm's Avatar chrapladm 04:39 AM 02-26-2014
SO what are the exterior dimensions of the room?

Are you still getting the Beyma coaxial speakers? And why did you decide on the TDH for the subwoofers?

I love the AE line but like other speakers better for the lows. Not knocking your choice just curious is all. I also love that you went with Erskine and going DIY. If I could I would do the very same thing.

Nup, the Beymas have been canned. Crap off axis response and Shawn has specified Dipoles so that's what I am doing. If I was going monopoles I'd have Paul Spencer design some for me

Going with AE for the subs because (a) John reckons they're fine to hit what I need them to and (b) they are shallow enough to fit where I need them to go

The two with the PR's will do 114dB at 20hz and about 110dB at 16Hz - so two of those, some room gain and 3 other smaller ones should be adequate

Hey there Peter,

So, how is it all going mate? Hope that you had a great holiday and have returned refreshed and ready to get stuck into your room again. Plans look amazing - great use of the space that you have.
Elill's Avatar Elill 02:05 PM 03-12-2014
Hi Mate,

All good here.....busy as a $2 whore in the main street of Mount Druitt. Holiday was great, as relaxing as it can be with a 20 month old running around! good though

I'd be doing the wiring this weekend if it weren't for a request for new garden beds by my better half.....with some luck I'll have the drywall done in 4-6 weeks and then progress will slow for a while whilst we save some cash. I took advantage of the better AUD/USD rate last week and ordered all (except the tweeters for the rears) speaker drivers........ten thousand bucks worth......kinda put a hole in proceedings
Elill's Avatar Elill 11:50 PM 05-03-2014
Right, some real, honest to god progress:

1. HVAC Finished (well the initial bit)
2. Speaker cable in
3. Data cable in
4. HDMI cable in

Next up insulation then ply! yay!

Have I missed anything? (electrical cable already done)

Speaker cable:
- 3 x the LCR's (all active 3 ways)
- 2 subs up front
- 1 sub each side
- 1 sub rear
- 2 x to each of the 4 rear speakers

Data cable:
- 2 x projector
- 1 x main light switch
- 1 from back to front of room (possible mask control)
- 4 to front of room (already there.....)
- 1 to xbox location
- 1 to riser

HDMI:
- 1 to projector
- 1 to xbox

Here are some pics.....not very exciting:

I think I asked Peter about those but not sure if he ever answered, so...Where did you buy those from?

Not sure how I missed that there. I just ordered midrange drivers from them and always look at their website. Must have just slipped my mind.rolleyes.gif

Hi Peter,

Good stuff !!

It sounds like you've got everything covered except maybe extra speaker cable for height channels ?

Cheers,
Elill's Avatar Elill 09:38 PM 05-05-2014
Hi Peter, I had thought of that, but I ran out of cable! Who'd have thought 300m would be enough in my little room.....doesn't help the rack is upstairs.

It won't be hard to bring them in later if required.......I say that now biggrin.gif

G'day Greg,

All good here.....usual story, not enough hours in the day......its killing me I cant find time to visit you and PeterM.

The only update from the above is that I have finished the insulation on all bar the longest wall.......I ran out last night, 2 bags short!.....grrr

I am building an aquaponics system that has consumed every waking minute, so the theater is back in slow mode whilst I get that up and running. With some luck I'll try to hang a couple of sheets each week in the interim, ply first.

Cheers,
PK

I knew the rapid progress was never going to last .. you youngsters have no staying power ! tongue.gif

And BTW what the hell is an aquaponics system ? Fancy name for a fish tank ???

Cheers,
Elill's Avatar Elill 04:23 AM 06-02-2014
Bah, too tired to come up with a witty response! Basically if it rains I am doing HT if its not I am in the garden building this....

Aquaponics is growing vegetables in fish ****.....more or less. Got a thread on it here http://aquaponics.net.au/forum/threads/new-diy-system-chop2-1000l-tank-sydney-wip.6526/

Some good info on what aquaponics is here:

Its only 1/3 finished, but here is the WIP of the grow beds and sump tank. The little bit of green tank you can see is a 1000L fish tank that will go round the side of the house. The blue barrels are for DIY bio filters and solids filters



FWIW, the theater is inside behind that brick wall
Peter M's Avatar Peter M 02:46 AM 06-03-2014
Fascinating ... I hope you enjoy eating the vegetables and listening to your pumps whilst sitting in the unfinished theatre !!

What ??? You were expecting a different sort of reply ??!!

...so there is a similar system for houses wanting to be off the grid...the water used to water the plants is from...the toilets! The "stuff" is kind of ground to be more fluid ("black water") and flows into the hydroponic plant bed and 50' (15 m) or so later it is considered "Grey Water" and used to water the rest of your garden. The plants thrive and absorb lots of "nutrients". It doesn't actually smell which is good since this would all be inside in colder climates. If you can get over the thought of eating vegetables growing in...well you get the picture. Just like some of the produce imported from China. I guess the fish might want to be a bit more than 50' down line though, unless you include some carp.

no...........was Ada's 2nd birthday party today...............41 people round here for "brunch"..........they're just left...........bloody greeks lots of work/cooking/cleaning etc

It is coming along slowly, one thing I do need to add is an XLR cable for my measurement mic. It'll be good, I can sit up here and run calibration till the cows come home and not annoy anyone

Just moving a post here from Roger's Deadwood Theater thread:

Hi Roger, interesting. I am planning something similar (albeit a long way off actually implementing):



Looking at your Post #6 , you (we) dont really have room for front heights? have you thought about it?

Edit: apologies for the crude representation of the Atmos speakers, you get the idea. I am probably going to DIY something like this:

The rear speakers are elevated 130 deg (the zone said to be 125-150 deg), which, at 10 deg higher angle if incidence than the fronts, may seem steep but it is just 30 deg above the surround "plane" which is elevated 20 deg for all 4 surround speakers. I think a 30 deg offset is necessary to really distinguish the heights from the surrounds.

Your front heights are clocking in at ~52 deg elevation, which s the top end of the recommended range. And the rears at 115. I think these will work fine for all concerned.

In that speaker model, is that horn for the tweeter?

I realize it is too late to worry about it, but even though the venerable Erskine group defined it, I feel the surrounds should be more forward, for better envelopment for the front row (MLP is there, right?), and it will not harm the rear effect at all. See diagram.
