CBT build thread
Wanted to try a pair of CBT arrays as a possibility for home theater. The only commercial offerings are the PE kits. I like the CBT36 but thought a little more displacement would be helpful for theater duties, so I designed a cousin using the slightly larger Dayton ND105 vs the ND91 Keele uses in his kit, 16 per array. The tweeter will be a peerless frameless 3/4 fabric dome, 48 per array.
To simplify wiring and decrease losses through voltage dividers needed to achieve the Legendre shading of driver output I'm going to use two amplifier channels for midbass and two channels for tweeters per array with DSP to make appropriate filters. Voltage dividers will still be needed but the upper half of each tower will be down -3dB digitally to start.
Based on expected seating height the array will need to be at least 60" tall. I'll keep the 36 degree arc of the PE kits as the shading drops output so much beyond that there isn't much point in continuing it further.
