Well at least if hes going to buy bose, hes buying the 301's ,which are the only ones that sorta sound good, and the best buy for the price in the range,,but really if hes getting them for $100, he wont find a better pair of speakers for that price. Whats out there for only $100 really?
Bose is over-priced cardboard and pressed-wood junk with fake tweeters and crossovers, and most people are ignorant suckers, which is why its getting harder and harder to find any decent stereo gear in chain stores like Best Buy, etc.
I have a friend that spend $3000 on stereo crap from stores like Best Buy, etc.
He bought Onkyo, Cerwin Vega, Monster Cables,etc.
Didnt sound so great for the money, but he thought it was great.
If it were my $3000 and i had to buy a stereo with it, i would have gotten Rotel, NAD, Cambridge,Paradigm, etc.
You can get a decent beginner rig going with entry level name-brand equipment like that, for $3000, but not at Best Buy.
Let your dad just buy whatever he wants, and when you buy your system,let him hear it, and dont say a word.
