In my opinion, the Alpha Series speakers are without a doubt the best combination of sound-quality, design and construction. They are extremely light, extremely good looking, and with either the Reference or Premium series upgrade, they sound quite good.
Keep in mind that you will need a quality amp to power them, and spending a little extra money on power will pay off big in sound quality. Just the same, scrimping on power will almost guarantee disappointment with the sound quality.
You can't go wrong with these speakers, so if you like the look of them, you won't be disappointed with the sound quality.
