I would never buy anything without hearing it, and the only opinions I listen to are ones based out of fact. If you are going to listen to an opinion, demand an explaination.
Consider this: I like Dual concentric speakers like the tannoy 8 or 10" model, here's why.
When sound projects from a speaker cab with more than one driver, the drivers are all a different disance from you. Sound travels at a certain speed and therefore if speakers are at a varying distance, it will take longer for sound from the farther speaker to reach your ears. When designing crossovers for speakers, a compensation must be made for this, and other factors in order to "line up" the sound. There is a difference between good crossovers and bad crossovers especially in this area. The dual concentric is a design which covers the full spectrum of sound from one cenetral point, thus eliminating the issue mentioned above.
I am not suggesting you buy these, unless they fall within your budget. If they do, then tannoy makes good models that I reccomended above. I do own alesis monitor ones, which are a conventional speaker and I find them to be excellent, and economical.
I just wanted to point out that the -"wow these are really good you should buy it right now"- :s: testimonials are okay, but if you are going to listen to someone, demand a sensible explaination, and then keeping that in mind, go and listen for yourself.
Also it may do you some good, (if you are inexperienced at choosing speakers), to read up on what makes a good speaker good, how to read and understand the graphs and charts issued with the speaker, and some ideas on how to listen to a speaker.
You can buy audiophile cd's which are designed to audition a speaker system, and these discs come complete with instructions.
Good luck.
