Stands for Reference 3A MM deCapo-i

The tweeters should be about ear height. The center of the deCapo tweeters are a touch over 12" from the bottom of the cabinet. My stands are 25 1/2" high, which gives the right height for me sitting in my usual listening seat. With the deCapos, I would err on the short side rather than have the speakers a little too high. If the stands you're looking at have adjustable footers or spikes (esp. if front and back can differ), you shouldn't have any trouble getting your speakers at just the right height.

There are many threads on this at the Reference 3a Cirle on audio circle. The cirlce is realitivily new, if you go back a few pages you wil find a bunch.

Take a look, they are very helpful:

I will also save you a bit of reading by giving you a run down, but there is still other information worth reading. Basically they say if the middle or the top 1/3 of the woofer is on axis with your ear that is best. It is not like other speakers were you put the tweater on axis, on 3a's it can be a little bright sounding if you do that. I would listen to yorus and start to lower or raise your self accordinly until it works best for you.

Cheers,

I use the Mpleshade Gibraltar solid maple stand ,it's only about a foot high,more or less. It will give you incredable bass response without upsetting the overall balance. Soundstage is wide/deep and center image is the same as a conventional stand.Hard to believe i know,but I've tried both and the music just sounded fuller with the mapleshades. check out the theory behind the stands and some of his other tweeks at mapleshade records web site.

Well, Nickway's summary of Audiocircle threads is interesting, and different from the setup I ended up with. When messing around with speaker height, I definitely preferred my ears at or above tweeter height. I thought the sound was smoother and more coherent from top to bottom frequencies. It did not sound brighter than when my ears were closer to the midrange-woofer axis -- counterintuitive, perhaps. So many factors... I hope you get stands that will allow you to try a range of "heights" (maybe by tilting the speakers).
