I just purchased a pair of "Response" inch and a half midranges from Ebay, I was going to use them in a cheap 3-way crossing to some iffy 8 inch from "DickSmiths" last clearout sale, then i thought perhaps they perform cleanly enough to use as a loe tweeter nd cross to a ribbon at 6 or 7K, can anyone give me a reasoned critique of these drivers??
I like the "response" 2inch dome ( it is a clone of the scanspeak after all) but have only heard ont other set of speakers using this midrange.
if I use it with a ribbon I will probably use the Vifa P17 as the mid-bass and a couple of 12's for the bass.
Input appreciated and thanx in adavnce
