There is definitely a "safety net" when buying commercially. Six weeks to figure out if I like an SVS offering. Don't like it, I'm out shipping to send it back.
Part of my trepidation with the DIY route stems from a lack of confidence in my ability to get the finished product dialed in for my living room. Although to be fair I can say the same for a commercial sub.
The same is true with my plasma. The picture is pretty good but I always wonder if it could be better. I suppose I could have it calibrated and there are people I can hire to help with the audio setup as well.
The retailers in the Dayton area seem disinterested in really helping. I'm one guy, buying one subwoofer for under $1000. They looking for the big sale and I'm not it.
I posted this earlier in a PM I sent to GranteedEV:
I went to Parts Express on lunch today. None of the employees knew anything about home theater sound or DIY speaker building. They had a BIC F12 ($230) and a Dayton 15" sub ($950) in their demo "room".
The guy who helped me turned on the 15". They had Revenge of the Sith playing. All I heard was loud, boomy, low-frequency noise. He stood there with a huge grin on his face and told me that he wanted one of those for his apartment. I thought it was awful. I had him try the BIC and it sounded just as bad, only with less impact. Another sales guy walked in an said the BIC was best sub they had. I know their demo cubby hole is not an ideal environment and that neither of those subs were anywhere close to being dialed in...
But it occurred to me as I was driving back to work....I don't know anyone in my circle of friends and acquaintances with decent home theater sound. Most don't have anything at all. I have a buddy who has a nice front projection theater in his basement but for the sound which consists of a low-end Sony AVR, a hodge podge of old off-brand speakers, and an 8" Onkyo sub from a HTIB. I go there a few times a year to watch Bengals/Browns, the Super Bowl, and his annual Oscar party. But the wife and I quit watching movies there because the sound was godawful.
You go to Best Buy and either nothing is hooked up or its just boomy noise. I think one reason I have never owned a sub is because I'm subconsciously trained to believe it is not possible to achieve quality sound at home. Because I have never experienced it.
My next goal is to find some DIYers and home theater enthusiasts in the Dayton/Cinci area that would be willing to demo their systems and share their experience. I want to hear something that sounds amazing. I want to be inspired. Ultimately, I want to do this right so that when I have friends over to watch movies, it will be a memorable experience that melts their faces.
I'm supposed to go see the guy at a local retail who sold me my Paradigms 10 or 12 years ago about a subwoofer in about an hour. I talked to him on Saturday and he recommended the Def Tech Prosub 1000 for $499. I told him earlier today that my budget had a increased to $750 or $800 and he mentioned a Golden Ear 10" that he wants to demo for me. We'll see. I specifically asked him about SVS, HSU, and Outlaw because they're frequently recommended in my budget. I wasn't expecting a big thumbs up but at least he had heard of them. We'll see how the audition goes.
I realize I'm probably borderline crazy by fretting this decision so much. Most normal people would have bought a Polk sub at Best Buy, brought it home, plugged it in, turned all the dials to max. Sigh....
