Beautiful! this is one hell of a project, kudos to you sir
If you don't mind, can you share with us the details like; drivers used & implementation, crossover settings etc. I assume the top 3 drivers are OB? TIA.
Thank you sir.... It's my weekend & holidays project ...
Yes, the 3 drivers mounted at flat panel. Woofer w/ H frame enclosure, open at the back but front form like Bandpass type. Originally, it's 12" woofer but found 15" which matches well with the configuration. So, it's now version 2 w/ 15" woofer. Midrange is 6.5" vintage wharfedale coated paper cone (very open in vocal). Twt-1 1" seas & Twt-2 kenwood horn.
Cut-off freq. bass- 80hz/12db, mid- 130hz/6db (low) - 3.5khz/12db (high), T1- 3.5khz/12db~ 22khz(max), T-2- 16khz/12db~ 50khz(max). Mid,T1&T2 are fixed attenuated to not use L-pad. Used same notch filter and impedance equalization from driver original crossover. If you notice freq. gap bet woofer & mid, in theory and number there's freq. hole but in real world of dipole environment our ears will not hear it. I also made the BP low 6db, @ 1 octave it covers down to 65hz. Fine tuning were done by extended listening sessions and opinions from friends who have different sound quality perceptions...
