Help with my new small dedicated room

[stevo1980]

Hi all,

Was looking for some advice on my new dedicated home cinema room. The demensions meters are 4.5L, 2.5w and 2.35H . I have two question. Reading Floyd's book it mentions that two subs placed in the middle of the front and back wall will even out bass as long as you are 25% from the distance away from the walls. Is this in reference to the front and back walls only or the side walls also? If it's including the side was it almost seems pointless in running two subs as I will have two huge nulls .625 meters in to the room either side of me? Second question is again related the the small 2.5 meter width and with regards to side speaker placment. Given that the sofa will be 1.8 metres wide meaning speakers will be .35 meters away from the sides of the sofa, should I be placing the side speakers 2 feet above seated ear height and should these be pointed over head or at the seating area?

Thanks in advanced

I would say get two subs anyway. Use the subwoofer crawl method to see where the best place is to place sub #1: this is where you place the sub in the listening position and then measure the sub's response with a calibration mic in possible locations it can be placed in. Use the spot with the flattest frequency response. Place sub #2 in the spot that fills in the biggest dips in frequency response from sub #1.

As for the side surrounds, I would place the speakers overhead facing down to the listening position. Keep them above anywhere where someone could hit their head from walking underneath. I think these JBL 8320s are really good for that application. You can mount them high and out of the way. They are sensitive speakers and with an 8 ohm resistance. They are also THX certified, in fact, they are the least expensive THX certified speakers on the market. That means they are extremely high bang-for-the-buck speakers. $500 will get you a pair.
