I've been considering my side-speaker options for my new HT room which I hope to useable pre-Christmas. I'm a Di-pole lover. When I got my TDM34DS's it absolutely transformed my room giving me the enveloping sound I always wanted. My current room however allows no option for 7.1 and very little choice of surround speaker placement. My new room is completely flexible in this respect. Because of the size of the room (42ft x 20ft Approx with around 35ft between fronts and rears) I am considering 2 pairs of sides. If I go for Di-Poles careful placement can allow each pair to be in the null position for each of the 2 main seating positions. There will currently about 15ft distance between the front chairs position and the sofas further back. I was previously considering adding a second pair of TDM34DS's sides which would give the room Kef Ref 4.2 Fronts Kef Model 200 Centre 2 X TDM34DS sides Kef Ref 2.2 Rears but I can see some problems with this. The intended forward firing driver of the rear pair will be firing in the direction towards the back of the front seats and similarly the rear firing driver of the front pair will end up aimed at and in front of the rear seats. Suddenly direct firing seems a better option again. I have room to choose between floor standers or wall mounted options. My concerns are that many direct firing speakers need to be away from the wall behind them to give optimum performance. Any thoughts? Mark.
