Again, thanks much. I'm leaning towards the Alpha 8a from Amazon because when I included shipping on the Dayton, the price--even USPS almost matched the price of the speaker! And I know for a fact that the price of shipping is inflated on their side. I shipped a 10" speaker to Utah once and it was less than $40.
The Dayton is also available on Amazon. The Beta is only $5 more than the Alpha. The Alpha IS a decent driver. Let me know how it turns out.
