Dan,
Here are my thoughts based on some of our conversations which I’ve edited (with yours in bold).
o Sonically, are you happy with the presentation of your 5Bs? Yes, they sound beautful and clear. They just don't give me the 3 dimensional space I'm looking for.
I’m confident either of the small towers will improve presentation and provide you more fullness, but I doubt you’ll improve the dimensionality any (if at all…sorry, but you need another wall!).
o The surround field sounds to far in front of me when sitting in my normal listening position.
I was going to suggest you try moving your speakers nearer or farther from the wall behind them, play with the toe-in, then adjust your seating position closer to the sweet spot. However, your fireplace pretty much dictates your seating position. You should still play around with speaker positioning and toe-in because small adjustments can offer audible improvements. This may not get you “there” but, hopefully, maybe a little “closer”.
o If you’re basically satisfied, then what, precisely, do you find missing with your present setup? 2 channel music performance needs improvement and a bit more spaciousness/integration in the surround field for movies.
Either of the small towers will be an improvement for 2.0/2.1 listening, and for any other format for that matter. Regarding the surround field, I think I recall seeing a picture where your rear surrounds were mounted around ear-level directly behind your seating position. If true, then IMHO, this is too “direct” and counters your desire for spaciousness. Here’s a thought (and please don’t laugh)…I’d try to temporarily aim them upward toward the back wall and ceiling, play around with the angularity, EQ and time delay, then see what happens. Hopefully you’ll get a more diffuse sound with lots of reflections. If you like this, then figure out a way to make this more visually appealing as a concession to your wife (hide them with a planting since horizontal directivity isn’t a factor anymore?).
o Since my kitchen is adjacentI also like to listen to music while I am cooking and cleaning and I do a lot of that stuff. The 5B's just don't give me enough fill.
Nothing you’re contemplating is going to solve this problem since most of what you’re now hearing in the kitchen are reflections. See my earlier post for your kitchen speakers.
o one thing I have noted while my 5B’s are away is the Denon seems even more powerful just pushing the front three.
The amplification demands on your Denon have been reduced because you’re running more sensitive speakers with the 92 dB JBLs.
o Did I start off with the wrong speakers in the first place?
I don’t think so…it’s just that you and your system are now evolving.
Concerning evolving and upgrading: maintain your interest in this hobby, continue to explore, study, investigate and learn. If you’re patient and contemplative, I suspect one day you’ll hear yourself saying: "Why should I, I've already discovered my golden soundstage." And if your wife is anything like mine, you’ll hear her saying…”thank God.”
So, what do I think you should do?
Discuss this with your wife and, if you both decide you can swing it, go for the 5Ts if you both agree they fit your room. Yeah, I know you say you don’t have upgradeitus but you sure display a lot of the symptoms: if you were to go for the 4Ts, I think you’ll soon find yourself asking…”what if?”
To your question:
o Let me ask all you men a serious question. Is the WAF a really important factor in this whole process? She seemed saddened with the thought of losing the center and the surround in favor of 6T's.
At last…something for which I feel amply qualified to provide an answer!
First of all (and of least importance), there’s no way in the world I’d give up the capability of a 5.1 (or more) for anything less when I can always turn OFF what I don’t want ON.
But, more importantly, I’ve just gotta’ ask…are you freakin’ serious???? It’s a family room and she’s the most vital part of your family! In addition, she’s supportive of your desire to find something better, willing to sacrifice and spend a little more, and thinks the small towers are “Cute”! Sadden this young lady???? No way in hell would I ever consider this: you’ve been blessed with a keeper, Daniel…and she’ll never ever cost you a lung!!!
I hope some of this has been helpful.
Fred
BTW –
Whatever that turtle-looking thing is on the right-hand side in one of your pictures, it appears hard and shiny…meaning it’s reflective. You should start parking it to the left side of your room where you need the reinforcement. ;-)
