Harbeth 40.1 - Need some tips on placement from current owners.

Nice! Congrats Grannyring!

I'd like to have your dilemma! I have M30.1s, so not quite the same thing, just the top 1/4 for half the price : ) Not sure my siting will translate to the big brothers, but I used the Cardas method to get in the ballpark and tweaked to taste from there. That worked well overall, so something to try maybe with the big 40.1s. You have a lot more room than I do. My 30.1s are in a 12x17 space.

I'll bet they'll work great nearfield. I sit about 8 feet away from my 30.1s and they are about 6.5 feet apart with some toe-in, about 15 degrees or so. They are really not that fussy and they aren't heavy, so it's easy to play around with different locations.

Let us know how you get on with them! I'm excited for you!

My room is similar to yours...  18' x 26' with ceiling ht. varying from 7 to 8 feet, with carpet over concrete pour (basement).    Mine are approx 7 feet apart, pulled out approx. 4 feet from the front wall, toed in approx. 15 degrees and I sit approx. 9 feet away.  I love 40.1's so much I'm on my second pair.  Hope you enjoy them!

Pdreher, oh my why don't folks talk about these speakers more! What a revelation! So rich and full bodied with all the details of the finest speaker, but not thrust at you! 

I love them. 8 feet from the wall behind them, 7.5 feet apart center to center, and I sit 9 feet back from the front plane of the speakers. 

Slight toe in. They remind me of my Soundlab M1 speakers. No kidding. They fill the room with rich, full bodied music. Effortless and with a ton depth. 

at this price point there a lot of good sounding speakers to choose from--spendor,atc,proac.All british which come  to my mind:)
To speak abaut this paticular speakers,somebody must own or have some experience.I understand your joy to share this joy with music lovers:) 

This is true. I have owned many speakers through the years and these are so utterly different in a pleasant way. They do need a large room and some work to dial in. Once set up properly with the right gear, they are very special.
