Well, Pogre, you're right, I did ask for an opinion, but I also stated what my current options are. I know they aren't top of the range but it's what I can get right now. I was just hoping that someone might have some helpful advice about which would be the best of those options. Whether ShadyJ meant to be dismissive or not, that's how it came across to me. Elitist, even. Would it really have been so hard to just say the best of the bunch is the Wharfedale -without having to insinuate that my money stack doesn't quite measure up?
Lovinthehd - you're right, I'm not in the US. I asked here because I've been reading articles here for a number of years and have always found them helpful and informative. I've learned a great many things from simply wandering around the site - and for that I'm very grateful.
It seems to ME, that either you're a very sensitive person or english is not your native language.
Shady'd response is accurate on both fronts: SW-150 is LIKELY to better sub out of your (in my view) very random selection, simply due to largest driver.
He's also correct saying that thou it will likely be an upgrade from Onkyo sub, it may or may not be sufficiently sized for your space.
The thing is sometimes is best to have no sub at all, than to "getting by" with inferior sub.
One last thing, we are all human beings, most of us doing it as a hobby while getting nothing back for our time (expect thanks, sometime) and expertise (and trust me - it take very significant time and lots of reading to get to level of knowledge of people like ShadyJ and he's not even most knowledgeable member (me neither).
With that said, you come here, looking to get expert for nothing, you should expect occasional annoyance for clearly inferior products. We are just humans.
