SB17DXT

This is one of older projects I did some years ago, and also one that did not lead to satisfactory result. 

The cabinet had 15-18l net volume, and larger facets around tweeter which shown to be beneficial for the linearity of tweeter on-axis and off-axis performance.

All measurements were done from 70cm, applied gatting ~4ms. Crossover modelling was done in Vituix v1, v2 was not yet available back then.

Measured individual drivers responses were promising very nice overall frequency response and off-axis performance. Measurement axis was between SB17 and DXT flanges. Drivers were mounted with 8mm gap between flanges.

Despite all my efforts, listening tests, and crossover tuning, I was not able to achieve good sound, there was still something strange, overall tonal balance was wrong. My first suspect was DXT, so I swapped it for Satori TW29DN, re-measured and re-modelled crossover, and this brought immediate improvement to the sound. Second step was to swap SB17CAC for Satori MW16P, and this finally provided the sound I knew from Jurko and Ghibli, the sound that is vivid, enjoyable and plays all music genres well.
