Tenshi is Japanese for angel. This very well describes my niece that I am building these for. She picked the color, a very beautiful tealish tone. Drivers are the Zaph Audio ZA14W08 woofer and SB Acoustics SB26STNC tweeter. 5 components. Enclosure is 11H 7.5"W and 8D iirc Fb of 60 and f3 about 55. I used 1/2" bb ply (20x20 panels at Menards, $4 ea). A single cross brace runs side to side. The xover schem has the correct values but the tweeter should be normal polarity.
