How are you dealing with the comb filter distortion that will start to kick in at about 8,000 hz by using the press-in Neo's which have a c-to-c of about 1.6 to 1.7 inches? 13560/1.6= 8475hzI know somebody who did that and found that his speakers had a distinct lack of air and a wa-wa feeling to the upper frequencies.
