Help with Dunlavy Aletha

Research "Pearson’s Rule of Thirds".

Or just try different distances until it sounds the best.

Trust your ears.

Dunlavy recommended 2 1/2’ +/- 6”.

If you ever want to sell them: pm me.

I believe Dunlavy always recommended long wall placement so speakers could be placed wide apart while keeping them a good distance from side walls.

The problem with this as I saw it was unless the room was larger than average that could place the listener's head close to the back wall.  In my experience it is best to place both the speakers and listening seat(s) away from walls.

I know John loved bass (he played acoustic string bass) but the listener's head too close to the rear wall couples bass, rendering less definition.

I enjoyed Duntech Princess model for 19 years.  Best I ever heard Duntechs or DAL models was a friend's Princesses in a 20 x 18 room with an alcove at the rear.  That allowed great separation between speakers, away from side walls, with the listening seat well into the room.

Thanks everyone for your input. I discovered the problem I was in countering was wrong placement of listening chair sat it right in an 80 hz null. Moved seat one foot placed speakers 4 ft off front wall and it’s sounding very good. 

Yes, Dunlavy suggested long wall placement, and absorbent room treatment behind the listeners head.
