So I purchased an EA 500c. This is a 4 ohm wizzy cab with a space on top for the iAMP500. Makes a nice light combo which is pretty loud. But I will be playing in a 7 or 8 piece band tomorrow and I wanted a bit more volume. So I tried it today with my other cabs, both of which are 8 ohms. Paired with the LDS 12"-6", there was no appreciable volume difference from the wizzy alone. However, with the CLX-112 there was a big difference! I would say that pairing the wizzy and the CLX also blends the strengths of the two. You get more mids from the wizzy and the CLX adds some of the bass that the wizzy lacks. I have some samples here: ftp://ftp.seanm.ca/shootout/ The naming scheme should be obvious However, the samples do not really do justice to the combinations. Especially the CLX/LDS pair. This is a *very deep* combination and the depth gets lost in the samples.
