...to clarify or build on a couple points above:. Let me not apologize for substantially sized speaker cabinets. In a big room you will appreciate some big speakers.
Next, I just watched a video from Danny Richey (GR Research). He told the story of the $500/pr speakers at Best Buy that have to double in price TWICE before they get to you, so that the money spent on the actual woofers and tweeters in there is about $20!!! There are a lot of different ways to argue this issue, but the facts are facts. It could be the commercial speaker looks better, is easier to Re-Sell later, is supported by positive online reviews, etc. But there is always the dream (psychosis?) of building Wilson Audio clones for $2500, hahaha!!!
