Hello everybody, i am finally ready with my hi-vi project and i am fully satisfied, i didn't expected such a bass and sound clarity, the midrange is excellent, for the price i can want nothing more The tweeter is hivi-Q1R, the clear volume is around 16l. and 2 ports monacore br45. The only thing is that F6 moves too much when the volume is higher, maybe is something with the box volume or wool(4sm).

Is this using the same enclosure specs as your original post? If so, the reason is that your tuning is too high. Under Fb, the woofer will unload as the port becomes a literal 'hole in the box'. Extend the length of the ports with some additional pipe, or block one of the ports.Hello everybody, i am finally ready with my hi-vi project and i am fully satisfied, i didn't expected such a bass and sound clarity, the midrange is excellent, for the price i can want nothing more The tweeter is hivi-Q1R, the clear volume is around 16l. and 2 ports monacore br45.

I am not sure where exactly is Fb, but around 50hz the cone excursion is less. The ports are with trumpet shape and can do nothing with the length, i can put some foam in one of the ports or maybe more wool, but too much wool can reflect negative on the higher frequencies. I am not sure if the lower Fb is good idea for bookshelf speakers, isn't the 50hz good for this type of speakers?
