Can you now explain what you did to get the (braced) panels to be perfectly 90 degrees perpendicular to the floor?
Thanks,
Andy

My 3.6s are on Mye stands so there are threaded pointed inserts in each corner of the base of each speaker that you can use for leveling. Either by screwing each insert in (lowering) or out (raising) front to back or side to side changing the tilt in any direction. It's a bit "fiddly".My digital level (NOT Laser as referenced in previous post. It's separate from the LDM) reads to 90.00 so you can literally change the tilt in hundreds of a degree. This was a small but just noticeable change and I did this before I bought the LDM.
I also have sub-woofer towers with 5 x 10" drivers per side that flank the sides of the 3.6s crossed over at 66Hz. I haven't done anything with fine tuning positioning these yet but, based on moving them around so far, they're not so sensitive to small changes in placement. Interestingly the Genesis 1.2 owners manual suggests NOT setting up subs parallel same distance to the walls symmetrically to avoid exciting the same room modes.
When you're done with this, go build an addition on to your house as you'll have all the tools you need! hope this helps.

That sounds like a good device to have as well - can you tell me what you have?Still interested to understand how this "verticality meter" actually works? Shure you can match the line which it might produce with the (vertical) line of the panels ... but how do you know the vertical line is at 90 deg? And what make/model is it?
And re. " go build an addition on to your house as you'll have all the tools you need " ... I have already designed the "music room" in our new house and we have just started demolition of the previous structure - so "building" will follow shortly. :-)) I want to get these tools:
* firstly, to get my own speakers aligned properly, when the place is built but
* also, to set up a 'retirement job' setting people's speakers up for them.

Andy: I'm not sure these are readily available any more and the instructions for calibration are not that great. It was a little over $100 USD. There appear to be several other options these days and you don't need to get one with a laser.
I really like the Lieca Disto 7400X - it was about $250 USD. There were cheaper models, but they didn't have a tripod mount. Bosch is another option.
Good luck with homebuilding and best wishes for a happy and healthy retirement! I threw in the towel this past July.

a Bosch GLM80 plus a "level cage" which turns it into a spirit level. :-))
Your model Disto is not sold in Oz - the equivalent is (according to the guy I spoke to) a Disto X310. This is a robust unit with a waterproof cover so, given I will only use it inside, I went for the cheaper GLM80 as it:
* also has a tripod mount, and
* tells you what angle it's inclined at - ie. knows when it is horizontal (for measuring) or vertical (for making sure the panels are vertical).
GLM80 was A$260 (USD220) vs. A$417 for the Disto X350 - so nearly 40% less.
So, many thanks for your information. :-))

Just stay out of the water..... : )

Wow! That is amaaazing ! :-)) Perfect location but why oh why hold it in our winter? :-((
Alas, I am in Melbourne, so it's not a simple logistics exercise to get up to the Emerald City. :-))
And re. staying out of the water ... a year or 2 ago, a Special Forces group was doing a training dive at night, in Sydney Harbour and one poor guy got severely bitten by a large shark. Lost most of one arm, at least.

Andy
Rat Shack sells a good pocket size digital meter.
