DIY project (Ekta 2D + Visaton La Belle combo)

Dear all,

Just wanted to share my DIY full range active speaker project which is a combination of the Ekta 2D design of Troels Gravesen (tweeter + mid) and the Visaton La Belle ( 2 x 8inch woofers) where the Hypex Fusion FA122 of the Ekta 2D is replaced by the 3 channel FA253 Fusion amp.
Cross-over between tweeter and mid is designed by Troels Gravesen (with first order, second order and 4th order LR options, all in the range between 2-2.5kHz), and LR2 cross-over between mid and bass at 300Hz (same as original Visaton La Belle):

Below the frequency response I measured with Umik-1 and REW software. Is a combination of far field measurement (same as Troels at +- 70cm distance from the speaker with microphone height between tweeter and mid) and a near field measurement of the woofers (corrected for baffle step loss), where in REW I selected the psycho-acoustic smoothing option:

In the end - after hours and hours listening and finetuning the hypex parameters - I am now very happy with the results! ;-)
