No Thoughts on my room set up ?

well the room is about 14Ft wide by 24 ft long 8ft ceillings - open into dining room so it is set up firing the shorter way .
there is carpet on the floor leather sofa & love seat -also a large bay window about 4 ft tall and 5 ft wide . What else do you need to know ?
I can get some PIX of the room if it helps

Thanks all for your thoughts -
The carpet is thick & has a thick pad,the walls are sheetrock, I do not think there is much ehco from a clap
I will take some pictures and post a link so you can see the layout or the room there are material blinds on the windows but not heavy drapes.

As for the set up the Denons crossover is set to 80 HZ and the paradigm 40's and CC-350 are set to large the rears are set to small, I also have a Paradigm PDR 8 sub The sub setting on the 3805 is set to LFE NOT Lfe& main.
At work I set up a large recption area with Paradigm SA-35s wich are similar to the 40's but they are in wall speakers They are driven by a Carver DSC-60 Pramp tuner and a Crown D-75 amp and there are Much more lows than my 40's Much more noticable at low listning levles and that is why I thought if I added an amp and used the denon as a preamp It would delliver more power to the speakers & get better lows and detail at low listning levles.
Thanks again & I will take som pix tonight

Hey Cheapmike , I am using 12 gague SJ Cable for speaker wire
I have herd good things about using power extition cord wire as speaker wire
I was also thinking about trying better cables wires & bi-amping BUT I can not bi-amp my denon & run an outdoor set of speakers on zone 2
Shadorne you got me more confused now I am looking for better lows for music not HT -low listning backround music
