speaker choice help (sorry!!)

[mercury187]

I know I posted for speaker help in the past, im sorry!! However I just purchased a onkyo 605 today online for 339$ shipped. Now I've looked at some choices in the past and I plan to sample some polk audio at circuit city but my friend told me you want the Hz rating or w/e to be really low, like 20Hz or 25Hz to be able to hear things like when ships in star wars fly over head cuz he said thats like 28Hz or something so youd want to be able to hear that.
My question is, he's referring to the frequency response right? And also, do i look for this in just the sub frequency response or all the 5.1 speakers (like center and fronts and rears)??? Like what kind of frequency response should I look for, for not only the sub but the other speakers as well?
Thanks in advance.

There's a whole lot more to sound/speaker quality than just how low they go. I very much doubt the speakers at Circuit City go anywhere near 20-25Hz in any meaningful way. Well, maybe the subs might...

yeah i hit him up again and he said it only matters on the sub..
I was wondering in 5.1 system how much sound actually comes from the rears?
I got 2 Polk audio R15's (http://www.amazon.com/Polk-Audio-Two.../dp/B00006I5O4) I was wondering if I could use those as rear surrounds for a few months until i got something better? Their a little large but?

Was thinking of testing the following out (except the sub since CC doesnt have that particular one):

Center:
1x polk CS2BK - 220$ JR 55Hz - 25kHz, 90dB 175W
http://www.jr.com/JRProductPage.proc...urce=nsa&nsa=1

Sub:
Polk Audio PSW404 Powered SubWoofer - 264$ 25 - 180Hz 200 Watt Continuous (450 Watt Dynamic)
http://www.jr.com/JRProductPage.process?Product=3652388

Front L & R:
Polk Audio Monitor 30 Bookshelf - 151$ 55Hz - 25kHz, 89dB 100W
http://www.jr.com/JRProductPage.process?Product=4032685

or

2x polk MONITOR50BK - 158$ JR (316$ for 2) 57Hz - 24kHz 89dB 150W

Do you intend to buy a sub? Typical cross-over for mains with a sub in play are 80hz. But most speakers will already have a range starting range around 35hz, give or take 10hz. Make sure to get speakers with at least a 90 db starting point. The higher the db, the more power they can handle at low wattage and will deliver a more dynamic sound. Just as cranking loud movies requires. This will generally garantee a lower distortion rating at higher volumes as well. Just remember, in movies, you may not actually be listening at a continuous loud volume, but when explosiions, i.e. loud sounds instantly explode thru the system, you want your speakers to be able to handle these Spikes in extreme volume levels without distortion or damaging your speakes.

I updated my post.

uhmm you want your sub at a low frequency and you want your speakers to hit high frequencies


ive been looking at new speakers and i like KEFs 3000 line you can get it on ebay for $1k and thats a 5.1 system including a powered sub
http://www.kef.com/ht3000/ you can probably get better speakers if you go DIY or whatever but i like the look of the KEFs

Methinks you are confused. ;-)

A speaker's sensitivity is a measure of how loud it is (at a distance of one meter), given an input of 1W. It is nothing to do with power handling. The sensitivity also has nothing to do with how dynamic a speaker sounds; the sensitivity is an indication of how easy a load (for the amp) the speaker is. So, all other things being equal, a speaker with a lower sensitivity needs more power from the amp for a given volume than one with a higher sensitivity.

For example, for a given sound level, a speaker with a sensitivity of 85dB will need twice as much power as a speaker with a sensitivity of 88dB (3dB = a doubling of power), assuming each speaker presents the same load (resistance and inductance).

I forgot to include in my post that I ordered the Onkyo TX-SR605, if that makes any difference in pairing it with the element designs.

Fronts & Center - 60 and above
Surrounds - 80 and above
Sub - 20 and above
