Hi All,

I am new to the avsforums as well as to the concept of component home theater systems. Over the last two years i have purchased two "Home Theater in a Box" systems and i must say that i was dissapointed with both systems. Currently i have a samsung HT-C555 home theater system. While it performs average in mid range volumes, while turning up the volume i get a lot of distortion and jitter in the sound. The specifications of the HT-C555 (my current home theater system) is as follows.

The amplifier (along with the dvd player, radio tuner etc) is rated at 1000w.
Front speaker output= 166w x2 at 3 ohm
Surround speaker output= 166w x2 at 3 ohm
Center = 166w at 3 ohm
Subwoofer = 170w at 3 ohm.
Frequency range= 20hz-20khz
Signal to noise ratio=65db

The specifications of the speakers are
Front\\Surround\\center frequency range= 140hz-20khz.
Front\\Surround\\center impedance= 3 ohm
Front\\Surround\\center rated input= 166w
Subwoofer 40hz-160hz @ 3 ohm @ 170w.

So i guess what this means is that the amp can deliver 166w/c at 3 ohm right. I do not know much about speakers and amplifiers. But i know enough to realize that the system i currently own is low quality.

So i am now on a quest to build a component home theater system with a budget. My living room is around 16ft by 16 ft.

For now i have selected a few components, i would like your advice on whether these components are compatible with each other. I've read that if i dont select the correct speaker impedance for the av receiver i could potentially fry it at high volumes.

Here are the components

Front and Surround speakers=

Frequency range = 40hz-20khz.
Power Handling = 40w-180w.
Impedance= 4 ohm -8 ohm

Center Speaker has basically the same specifications.
I havent selected a subwoofer quite yet, but was actually planning on going for two subwoofers. I like more bass in a system.

My choice of receiver was the

sony STR-DH520 or the onkyo TX-SR309
(sorry i still cannot post links cuz this is my first post)

What i want to know is whether these speakers will work with these two receivers. Will they create problems such as the receiver over heating etc. Why have they mentioned an impedance range for the speaker set instead of giving a definite value.

Also hypothetically if i get a reciever which is not capable of processing either dolby digital or DTS, yet my Blu-ray player is capable of processing both sound formats, will i be able to output that through an optical cable to the reciever and will the reciever correctly send the sound output signals to the correct speakers in turn?

I would greatly appreciate your help and advice in this regard.

Thank you.

You should probably post over in the audio forum. This forum is more centered on building home theater rooms and is not centered around the equipment. I think you'll get better responses posting in one of the forums at the link below.
