depends, if you are looking for just spl then I would go with the two W0s. If you want a good combination of sq/spl go with the 1 W3. The one 23 might even take the two w0s in spl. depending on power. If I remember correctly the 10 w0 takes about 100 watts where that w3 could take about 300.
I would take the 10w3 or have you considered a 12/15w3? The W0's are alright but I prefer the other series. I hvae owned my share of W0's, 3 12's, 3 10's, 2 15's and I had 3 10w6 before as well.
I only have these two choices. I have two W0s in NY and a W3 in LA, and I don't remember what the W3 sounds like. I guess I'll switch them and hope the W3 is better. Thanks for the advice.
