@Scout's staff - I do have a powered sub: http://www.newegg.com/Product/Product.aspx?Item=N82E16882290034
. Not sure if it's the right power or size for the room but I do not feel like I'm lacking in bass.
My first thought was that your PSW is too small for the space, but I am a huge proponent of use what you got if you are happy with it. I'm no expert on PSW, but I would think a 100 - 200 watt PSW would make more sense versus the 10" 50 watt you have now. I would check with the more educated folks in the Power Sub forum section. You may also want to reach out to ack_bk (another forum member) who seems pretty knowledgeable on bass and uses in-walls as well.
What you said about a pre-out for an amp you are right I do not have one in my AVR. I believe for a pre-out I would need to go to a: http://www.amazon.com/Onkyo-TX-NR717-7-2-Channel-Theater-Receiver/dp/B007JOO4YS/
. Am I correct in assuming that?
Response - correct
Let's say I did upgrade to the above AVR that would then be enough to power my two rear speakers, so now you're saying I should get a 3 channel amp (any suggestions here would really help) then power my three fronts through that.
Response - Yes you would have enough power to drive the surrounds if you added a 2 or 3 channel amp. You could probably get away with a 2 channel for the L&R mains. I think your speakers are rated for up to 150 watts (8 ohm) but you should confirm this. For budget reasons, check out Emotiva (makes a 2 and 3 channel), Outlaw, and Onkyo makes an inexpensive 2 channel (good deal on Amazon), you could also look for used at consignment shops or on-line.
You also mentioned upgrading my front stage speakers. What is the reasoning for this? I know the S7's are old B&W speakers but I thought they were pretty good. The S7's are two-way but my understanding was the 3-way was really reserved for high end speakers and a general rule is that you are better off with a really good 2-way than a mid line 3-way. What 3-way in wall would you recommend? I saw in your set-up you have the Atlantic Technology IWTS-30 LCR but those are quite a bit out of my price range currently. Back to my original question (sort-of) if I did upgrade my fronts can I go outside B&W safely?
Response - Adding more power to your mains/front stage may solve your problem and no upgrade needed. I just thought they may be too small for that size room. I actually like B&W speakers. Another thought would be to pull one of the speakers out of the wall and see if back boxes were ever created/added - I believe the Signature 7s were not enclosed. Adding back-boxes may also help with better sound quality.
If you did decide to upgrade some day, yes you can move to a different brand as long as you replace the entire front stage. Keeping the surrounds would not be a problem since they are for ambient sound. If interested, look at Def Tech, Atlantic, Speaker Craft, and B&W, etc. In-walls have come a long way - buying enclosed is the preferred structure.
So in summary your suggestion is in short term properly power what I have, then in long term look into upgrading my my front stage.
Response - Yes, I'd try the power route first to see if that solves your issue. Even better if you have any friends that have an AVR and amp you could do a demo on to see if there is any improvement in your environment before making the investment.
