Thankfully, then, I found that the Inspire T3030s delivered. With separate tweeters and mid-range drivers on each satellite, the sound quality really is excellent. I can hear mid-range sounds as clearly as on my £300 home hi-fi system and the extreme high-end of the treble is also reproduced with excellent clarity.
Out of the box, I was surprised by how small the sub-woofer is. However, its looks are deceiving as it can dish out some very satisfying, deep and clear, bass notes, especially now that I've placed it in the corner of my room. It's not Earth-shatteringly loud, but it does the job. My only complaint is that if I turn the bass up more than about half way on the dial the sub-woofer starts to vibrate a lot, distorting the sound. However, this isn't really a problem for me as the low notes are more than adequate with the dial set to three (out of nine), and as I've said before I don't require over-the-top bass anyway. You may like to knock a star off the rating if you're the kind of person that likes to have the sub cranked up to the max all the time, though.
Overall I'm extremely impressed with the quality of these speakers and the in-line volume control and adapter for games consoles are added bonuses. For the money, these are an excellent buy.
