I've purchased a set of HT-10's for the L+R positions in our small 5.1 home theater to compliment an 88 Special I built several years back. They will take the place of my Forte II's, which are fantastic speakers in their own right but they never blended well with the 88 and are better suited for stereo use. The well-packed kits arrived over the weekend and as of this posting I've assembled the crossovers and glued up both cabinets. All the panels were straight and everything fit together just fine. The only issue I encountered was the vertical brace protruded a tiny bit past the top/bottom pieces and had to be trimmed (I used a sharp chisel to shave it flush to the edge). On the crossovers I opted to shorten the leads of the inductors for a cleaner look. To expose the bare copper I scraped the enamel coating off with scissors and finished with sandpaper...there were no problems soldering to them. I also decided to omit the screw terminals and will be soldering the driver hookup wire directly to the board. I highly recommend getting the optional circuit board with these kits. Question: I have a couple sheets of 1" sonic barrier from PE and a few lbs of acousta-stuf on-hand. Should I both line the enclosure and loosely fill it with stuf?
