ok here we go.
Whenever I get asked these sorta Qs the recipients don't get what they want for an answer (the desired response is usually "Hell yeh - throw buckets of money around and take the salesman to lunch cause he's really lookin after ya!").
1. Most of the gear out there is really decent quality (especialy compared to some 'pro' audio). If you are routing your vision through the gear then check those specs though.
2. Don't get as hung up on brands/features etc as ROOM QUALITY AND
PLACEMENT3. Did I mention PLACEMENT? That is the most critical factor of all and to be honest you may well get better results from average gear placed carefully (and time-aligned with the amp etc) than sh!t hot gear placed lopsidedly (usually to keep the missus happy) or incorrectly. Do your homework here and even check the webbys for the brands you do buy to check their recomendations.
4. Klipsch gear I haven't actually heard, but I have noticed that they tend to use loaded horn designs (the deep squarish funnels on the tweeters) which i personally equate to PA sound and find not very flat in response.
5. Don't be tempted to go for a massive sub if your room is not huge. I have a single 8" Velodyne sub that is lovely sounding ($900). Tighter and more 'music friendly' is where my bias is, and it suits my average sized lounge room perfectly. Just so you know it is only 120 watts (real RMS though) and I run it on about 40% power. It kicks @rse on music and rattles the windows on movies cause it is super efficiant and controlled, not super fat/flabby and wobbly. More apparent bass does not mean better. A flatter (less noticeable hump) and more contrlled sub wins every time.
6. Don't get sucked into being impressed by razor sharp highs and bloated bottoms in the showroom. Most salesmen will try to impress you with that. Take your OWN music with you so you can hear the elements that you like (or dislike) in the gear.
7. More exxy does not mean better (usually it means better marketed). Example I used to have a pair of $3500 KRK studio monitors at work that I HATED. They were bloody brittle and really fatigueing and frankly overated as cr@pola. At very least they didn't suit me or the stuff I was listeneing to. TRUST YOUR EARS.
Yep, Frank Prowse is a good place - bit more pricey but good stuff and a bit more knowledgable staff. Check out a few places and shop around a bit and good luck grasshopper...

Oh a really well priced speaker brand to check out is Krix. Made in Sth Oz I think. I helped a mate buy a pair of tower 3-way speakers (not usually my 1st choice) and they were outstanding for the $1100 or so he paid for a pair.
