First time poster, long time Ascend user here. Before asking for advice, I'll tell everyone my funny story.
My original Ascend lineup was a 5.1 system:
-- 4 classic 170
-- 1 classic 340 center
-- 1 original Hsu VTF-3 (a pipe organist, I do love bass)
The 170s were mounted on those precarious Z-stands that Ascend used to sell. These have proven to be incompatible with my relatives. A while ago, my mother came to visit and managed to knock a 170 to the floor. Finding the woofer magnet separated and rattling around inside the cabinet, I tossed the 170 into the trash. As you might imagine, you get a very strange feeling when you throw away an Ascend!
I bought a pair of the new 170SE and put them up front. Having an extra 170 classic, I thought about adding a rear channel. Ultimately, laziness prevailed, and I put the extra speaker in storage -- or so I thought.
Fast-forward to recent times. While my in-laws were visiting, the male decided to "fix" a faucet in my upstairs bathroom -- without first turning off the water mains. The ensuing flood did over $7,000 damage to my home. During the cleanup, the second 170 was toppled. "It's OK," I thought, "I'll just grab my backup speaker." Nope. It was nowhere to be found. Further investigation discovered that it had been thrown away by a family member who had mistaken it for the first broken 170!
A lot can happen in five years...
So I'm left with my sub, a classic 340 and 170, and a pair of 170SEs. It's time to buy some new Ascends. My budget is about $1000. I figure I could buy 340SEs with pedestals for LRC, move the 170SEs to surround duty, and make the 340 classic my rear channel. Let's call this plan A. Those pedestals, filled with sand, should provide adequate tipover protection.
Plan B is to buy a pair of Sierra-1s (and stands) for LR. I'd keep the classic 340 in center. The 170SEs would again become surrounds, leaving the 170 classic for rear.
My HT is in a 15x17x8 room. 11x17 of this is used for HT. See the attached diagram. The huge projection screen limits speaker placement. I use this for 80% HT and 20% music, powered by an Outlaw 950/7100 combo.
My thought is that 340s in LRC -- plan A -- is best for me. I've been satisfied with the 170s thus far, although I do feel the need to up my treble EQ by a few dB. I guess I'm just not a "golden ears" type; as long as I am above the obvious junk for sale at the big-box stores, I'm happy. So I'm guessing the Sierra's are overkill, and I should just enjoy having the same very good speaker in LRC.
I guess I need someone to tell me I'm not making a horrible decision by sticking with the 340s over the Sierras.
