Hey Wayne, Thankyou so very much for the compliments! The tweeter is made by Pyle pro , I used only the cap. that came with it as the cross from mid to high. Also run an L-pad to help balance the 106 db sen. of the tweeter to the approx. 98 of the Eminence 15"er. Also doped and tweeked the 15 and foam /felt wrapped the rear of the tweeter. Sort of turned this coaxialy mounted tweeter assembly in a pseudo phase plug of sorts.Seems to do the job. This speaker has been designed to serve as an intro level audiophile speaker for budget conscious music lover. I have gone over more construction detaild on th Decware forum. Thanks again Darrel
