maxima95 - As mentioned, am not sure yet from tests that the Audax is too hot (the crossover clearly has mid/high built in loss to match the lower sensitivity of the woofer) as only had one instance where 6Khz, or so, was 3dB high. Perhaps the Halifax guy can provide the original Energy tweeter rating? He would not provide me with final plots: return loss, sensitivity, flatness, if he rebuilt mine - my engineering background requires that performance be verified, so I declined his rebuild offer. As am working with a known quantity here, the Audax, and results match the Auratone near field studio monitor in the mid/high region, will add a pad if required (to the rear plate) to complete my Audax/22 monitor conversion. Good luck with your project.
