http://www.geocities.com/foreverfai/teacmod.html Yup, recently got the Teac HTIB from costco for $280. This HTIB includes 4 - sats with 1 inch tweeter and 4 inch fiber cone 1 - center with 2x 3 inch fiber cone and 1 inch tweeter 1 - 100 watt RMS 7 inch subwoofer 1 - Teac AG-D8900 500watt DD/DTS receiver The Teac receiver IMO is alone worth the $280. It has S-video ins/out, 2xoptical/ 1xcoaxial digital in and 1xcoaxial out. This package sounded awesome while playing a movie....but was lacking went it comes to music....time to bring out the tool box Curiousity got the best of me. Once I received the TEAC HTIB, I took the subwoofer apart. To my surprise, theres no polyfill at all! Its just an empty box! The same goes for the speakers! No polyfill again! No wonder the sub sounded boomy and the speakers sounded hollow at times. Anyways, I went to home depot. Got some fiberglass fill for $8.50 and started stuffing the subwoofer/speaker cabinet lining. While I was at it....I also replaced the original 24 gauge wire which connected the crossover to the speakers with 16 gauge wires.....as someone pointed out on this site, "whats the point of using 16 gauge speaker wires when the wires used inside the speakers are reduced to 24 gauge wires?" WOW! What a difference! The sub sounds way better. Much tighter bass respond. The boominess was completely eliminated. The speakers no longer sounded hollow. B4 filling the speakers, the speakers always give out a echo/in a tunnel type of sound. But now with the fiberglass filling, the sound, especially the midrange, was much warmer and pleasing to the ears. All the vocals are accurately reproduced through these speakers. What do you guys think?
