Help me set up my new (to me) Dunlavy V's

flutffers, I owned Duntech rather than DAL, but general recommendations remain the same.

First, Dunlavy's designs could be placed a little further apart than many others.  So for one suggestion an equilateral triangle with 10 to 12' to the prime listener seat.  In my experience he always spread his speakers wide apart for show demos.

Second, they should be out from the front wall and away from side walls by at least 3'.  I think smoothest bass response came with the front of my Duntechs about 5' out.  With your 17' room width that will be tight on the short wall but may work well.  I'd try 3.5' - 10' - 3.5' to centerlines there.  John usually recommended long wall placement (possibly to get the width he wanted in an average room?) but for me this can place the listener too close to the rear wall.

I had Princess model which was the older sibling to the IV, a 3-way with 5 drivers.  My manual gave specs recorded at 3 meters so I assumed that was the minimal distance required tor the driver array to focus at the listener's seat.  Depending on how far out your speakers are placed from the front wall this is where the listener seat to the rear wall can become an issue.

For toe-in I found aiming the speakers at a common point about 3' behind the prime listener spot gave the best balance of response and imaging.

As implied by miller however, feel free to experiment.  Every room is a little different.

Good luck and enjoy.

fluffers, about the time I bought my Duntechs I developed a procedure for room placement.  That required taking measurements for smoothest (flattest) bass response as I moved the speakers out from the front wall 1" at a time.  Note my choice was to obtain the smoothest bass response, not finding the maximum output for a given frequency.  As they came out into the room the response curve smoothed out until it reached its best response, then began to deviate more if I moved them further.  That was a room dependent condition and was ultimately fine tuned down to the half-inch, so there is no absolute answer, only guidelines.

This is why miller's recommendation for experimentation is correct.

However I would question if this is a good speaker choice for placement behind a video screen?  I don't remember the precise distance but my Duntechs had the front baffle at least 4' out from the front wall.  Will it be practical to hang your screen somewhere between 4' and 6' out from the front wall?
