help thiel 2.4 placement???


i am having some problems placing in my room a pair of thiel 2.4, acording to thiel they should be far away from the walls, they recomend 3 ft at least from the back walls and 5 ft from the side walls.
i did this and i am not getting any bass, if i put them closer (1 ft) from the back wall i get much better bass but thiel does not recomend this.
right now i have them 2.5 ft from the back wall, 6 ft apart from each other, and the listening position is 8 ft away. sound is ok but i know it should be better.
does any body have experience placing thiels, please help
thanks in advance.

Nice post Redkiwi. From my experience with the larger Thiels, they do like their breathing room between the speakers. Typically, setting up an equilateral triangle with speaker, speaker, listener is a good starting point. I've noticed that the Thiel's need more space between them and the back wall than between them and the side wall. I believe it's normally best to keep those distances different from one another (e.g., the front center of the driver should not be both 4 feet from the front and 4 feet from the side wall). Trust your ears since general rules may not apply to your particular acoustic environment or to your tastes. Experiment as both Redkiwi and Jazzdude suggest. By the way, both location and degree of toe-in will matter as will, with Thiels, speaker cones between them and the floor. Good luck.
thanks for your answers, because my room is 12 ft by 15 ft, i could only place them 6 ft apart (because of the door of the room), but toninght i will have to change the whole set up of the room so i can position them 8-9 feet apart and 2-3 feet from the rear wall and 2 feet from the side wall, listening posistion would be 9 ft away. from that position i will start to move them around and look for the best set up.
That should help tremendously.

I have my 2.4's a little farther apart then Redkiwi suggests (maybe one foot more) but I also have them toe'd in quite a lot. (I tend to favor toe in because I like focus and prefer a small, focused soundstage to one that's bigger but more diffuse.) However, Redkiwi's advice is brilliant (as ususally) and I'm going to do some experiementing.
Slight clarification. I meant to say that isolation cones attached to the bottom of the speakers and affixed to the floor or metal pucks add a lot to the character of Thiels. That's what I meant by "speaker cones between them and the floor". These are typically solid brass cones with the flat side attached to the speaker via a threaded cylinder (i.e., bolt without the head) and with the spiked side toward the floor. The impact on the CS-6's was spectacular and immediately evident. Send me an email if you would like more details.
Ozfly: I take that what you are talking about is in replacement for the included spikes Thiel supplies with their floorstanding speakers?
