Looking to get what I believe is a laser level of some type.

I want to place it at he seating position at the head of the equilateral triangle/seating position to fine tune, so 60 degrees internal. That way I can try different placement in the room without spending forever measuring - just place the speakers and slide the chair into place.

 

Cheapest possible as this is literally all I'll use it for.

 

Any recommendations?

Bosch do a cheap and cheery unit that might fit the bill: https://www.bunnings.com.au/bosch-pll-1-p-line-and-dot-laser_p5660477

Thanks - it doesn’t look like it will do two lines with an internal 60 degree angle unfortunately.

Not sure why you need such accurate measurement?  Are you going to sit at the same position and same height always, within 1 mm?   A tape measure is more than enough to ensure you are sitting in an equilateral triangle.

i need it to compensate for my incompetence.

Buy some string, something to hang it off at all three locations and an old fashioned tape measure and you’ll be there in no time.

Tried and failed.

Use string. Don't bother with tape measure. 

 

Tie a loop around one speaker. Keep it loose so it can move freely. 

 

Run the string over to the second speaker. 

 

Pull tight and tie a knot to mark where the middle of your second speaker is so you have the width between them. 

 

Repeat with a string to the other speaker. 

 

Grab the two knots together and walk backward until they are both tight.

 

There is your triangle.

 

But the triangle isn't an exact rule.  I'm set up seated a bit forward of the apex which is a bit behind me. Then run a little toe in but still meeting at a point behind me.

What do you say a string and tape measure failed?  At the end of the day, it does the same thing as a laser tool. 

 

The equilateral triangle is not a miracle solution. It is one of many things that improve SQ.  ...

Tape measure bends, knots loosen, height of speaker to rest things on is different to the height of the seat.

Ty - but I don’t follow.

All I’m looking for is a recommendation for a ‘box of lasers’ I can put in the seat and see two dots hit the front of the speakers.

I have an $800 laser level that doesn't do what you want...

 

If you want a laser I don't think you want a level. More this https://www.bunnings.com.au/bosch-blue-30m-glm-30-finder_p0318104?store=7216&gclid=Cj0KCQjw--GFBhDeARIsACH_kdZcsksIxB_8Byna7iA7RfGd-f1j22k0qLcVU7n9mvUQW0HBFLlWVDsaAi5CEALw_wcB&gclsrc=aw.ds

 

This laser measures distances. Since you want an equalateral triangle, you just need all the distances to be the same. 

 

Measure the distance between your speakers. 

 

Then put it on the chair. 

 

Point at each speaker and move the chair until the distance to each speaker is the same as the distance between the speakers. 

This is crazy! Buying a laser to identify the exact position, but can you ensure you will always sit at exactly the same position everytime?  

 

Best wishes...

Ha. such a technical approach to a non technical solution. Just use a slack piece of string and adjust where it sounds good.
 

This conversation reminds  me of the people who buy speaker isolation footers that supposedly stop the micro side to side vibrations of a speaker.
 

How much does your head move while you listen?

 

I’ll bet your “micro” head movements are far more significant than any changes in the speaker due to vibration as as the cones move.

I think you mean "the equilateral triangle isn't an exact rule", Dr?

 

My seating position is perhaps a bit behind the equilateral apex ... but my spkrs are toed in to meet just a bit forward of my ears.

 

Try it ... I would suspect it will give you a wider "sweet spot" - for when you have friends over to listen.  

 

Of course ... if you don't have any friends - then don't bother.

I’m using a couple of these for speaker placement and alignment:

I don't think I have seen a 60 degree floor laser like you require. 45 and 90 degree no worries.

 

Better yet as mentioned above measure the distance half way between your speakers. Put a bit of string down from the halfway point keep it parallel to the side wall till you reach the listening position, bit of trigonometry later and you'll get your listening angle.

 

I kind of understand what you say about tape measures and strings bending as such. I remember having a heated argument with a Carpenter when he said you could square up the Pyramid of Giza with a piece string...A piece of string over 100 hundred meters long outside in the elements? Yeah right.... Luckily we are indoors and only dealing with a few meters. String or snap a chalk line and done right would see 98% accuracy. Good enough for this aspect of the hobby.

Yep, exactly. But 'the triangle'  was equilateral throughout the whole discussion I made. And I'd assume everyone would know that.

 

Due to room issues I can't get further back WRT to the triangle as it boasts 80Hz too much. 

 

And narrowing the speakers more to adjust the triangle dimensions just gives me other base issues. Plus the delay time on lateral reflections gets too high which has a far bigger impact on imaging. The delay I've got gives a bit of broadening and maintains good room ambience. 

 

So like I said, the (equalateral) triangle isn't an exact rule. 

 

Plan is to look at diffusion at some point, should be able to narrow speakers a bit, keep the imaging and not deaden the room, and either DSP or trapping for base. At which point I'd revisit positioning.

 

For now I'm happing with the 3-D imaging I get which is solid and wraps up to 200 degrees around me.

I don’t - thanks for that.

That only has one laser

OP wants one with 2 lasers to point at each of his speakers - which is WAY overthinking this

We just need Marc to purchase this and run a members loan system 

Why don't you buy two cheap laser pointers, just make sure they are in a cylindrical case.  I saw a set of three on eBay for about $16.  Buy a 60/30-degree plastic set-square (a dollar or two).  Tape one laser pointer to one edge of the set-square, and the other pointer to the other edge of the set-square.  If you have taped them to the correct edges pointing in the right direction, you will have your two laser pointers at a 60-degree angle. Cheap, and accurate enough for what you want.

Tape two together.
