In my opinion, the
Titan Alpha II is one of the best speakers on the market when it comes to combining solid sound quality and output, gorgeous looks, light-weight construction, and high quality. Sure, a horn based setup will be louder, but none of them look as good as the Alpha II, and they're all going to weigh two or three times more.
The Discus components are decent, but unless you plan on adding two pairs (which I would recommend), you should probably upgrade to the Reference series. Two pairs of speakers is really ideal, as that gives you enough surface area to really reach back behind the boat.
So when it comes to combining a complete package of looks, sound quality and high build quality, the Alpha II is second to none.
