Help with Setup

Hi folks,


So I wanted to list my system and get some feedback on it. It sounds good but just think the system as a whole should sound better? What should I replace what are the weaknesses etc. Thank You


2 Front towers are 2 JBS S312's http://www.crutchfield.com/p_109S312...bl+s312&tp=185
2 Rears are the Pioneer Andrew Jones http://www.amazon.com/Pioneer-SP-FS5.../dp/B008NCD2S4
Center Channel is a POLK http://www.amazon.com/Polk-Audio-Cen.../dp/B0018QROM2
Sub is a MTX http://www.bhphotovideo.com/c/produc...Subwoofer.html
And the Receiver is a Yamaha v367 http://usa.yamaha.com/products/audio..._u/?mode=model

Its in the typical 5.1 setup, 2 in the front sub in the corner and 2 in the back. Main thing im wanting feedback on is do these speakers even work well together, should the JBL's be replaced for something newer? Are the Andrew jones pinoneers okay to use as rear speakers in a 5.1 setup? Is my receiver good enough to power these speakers the way they need to be powered. Those kind of answers and feedback are what im looking for. Thank you!

Timbre matching is not so critical with the rears, but timbre matching across LCRs can be very important.

Your AVR probably has more than enough power.

If you are concerned about power, obtain a SPL meter to measure your preference for peak SPL

http://www.ebay.com/itm/30-130dB-USB...item3a8a27628e

The above is good but very inexpensive - under $30 and one heck of an investment compared to an AVR upgrade.

and plug the SPL you get from that, speaker efficiency, and listening distances into this online calculator:

Standard setup is the fronts at an angle of 30 to 45 degrees from the listening position, the surrounds directly to the side (90 degrees) to slightly behind (110 degrees) and the center above or below the TV and angled to point at the ears and placed at the very front edge of the shelf it is on.

Very rarely does a sub sound best in the corner because of standing waves and cancellation - it will sound "boomy" and hollow at different frequencies. Google "sub crawl" or "sub placement" for articles on how to place a sub correctly.

As mentioned, the three speakers across the front should be "timbre matched" so sounds moving across the front don't change the way they sound. What doesn't this system do well? Not enough volume? Not enough impact?

An obvious place to start would be bigger front speakers that were matched to your center speaker.

Polk Audio Monitor Series New Monitor 65T Three-Way Ported Floorstanding Loudspeaker - $200 ea (these go on sale often for less than $150, keep eye out for sale)
http://www.newegg.com/Product/Produc...82E16882290271

Another would be a really great sub with much more output:

PB-1000 300 Watt DSP Controlled, 10" Ported Subwoofer - $500

2-Ch (HT L/R): Oppo BDP-105 BD, Adcom GFP-750 pre, Bryston 10B Sub Xover, Bryston 4BSST2, Paradigm Signature S4 v.2, (2) SVS SB12-NSD subs, AQ & Cardas XLR

This is the best investment you could make to your system if you want to investigate acoustics of speaker systems, in combination with downloading REW:
https://www.parts-express.com/dayton...phone--390-808

You can connect this to a HTPC or laptop and see if you have any dips or peaks in the response, and where the highs and lows rolloff at, also by playing sinewaves you can measure the distortion the speaker is making at a given frequency.

Your AVR may have come with a measurement mic, which would be the second-best option.

Takes the guess work out of the equation.

Correcting the issues you find is a whole other topic.
Usually room treatments firstly, and EQ'ing secondly. (Room treatments are not always an option for people because of the visual decor impact/WAF; there are a few options to mitigate that to a degree...)

You need to tell us what it is you don't like about your system before we can tell you how to fix it.

That being said, the number one "bang-for-the-buck" HT upgrade has got to be a quality subwoofer, it can make or break a good sounding system. If the foundation (bass) ain't there to build on, the whole thing comes tumbling down.

Okay Im going to keep the S312's and find the JBL S series Center to match. Now the other question I have is about the Sub. Here is how big my basement area is. Would I be better off getting 1 NGX BAS 500 or get 2 Dayton 1200's? Or any other recommendations for 300ish range
Thank you for everyone's help

Pics help, but actual physical measurements would be better.
