Brett,
Go for the 19's for sure, you will not be dissapointed! I will not sell my 19's for anything, well I guess there could be a price up there somewhere. I will say it again, they are only harsh at elevated volumes. At normal to medium listening levels they are nearly "unbeatable" in detail and seperation. The lower end is outstanding as well with crisp, clean, and deep bass. They just do not move as much air as my Cornies, which is a very hard act to follow in any case.
They are 103 db efficient -vs- the 104 db K-horns, so they are very dynamic and enjoyable to listen to.
Hope this helps,
Greg
