[QUOTE="Antti Laine, post: 216857, member: 13538"] It may be beneficial to EQ 1500 to 3000Hz down something like -3 to -6dB and use +6 to +10dB high shelf from 3000-4000Hz upwards for the DH1A, depending what horn is used. DL15X has 3rd harmonic distortion peak around 600Hz, eq it down some -3 to -6dB depending taste. This should help to achieve more civilized sound at higher levels. Please consider using subwoofers in the system. I have been listening a similar combination constructed in one trapezoidal enclosure (2x DL15X + DH1A/HP940) + MTL2 subwoofers for some 20 yrs ago. Analogue EV XEQ-3 was used with 80 and 800Hz/24LR Crossovers. The 800Hz 24dB LR highpass module contains aforementioned high shelf filter to bring out the sizzle, but I cannot recall if the 2,3kHz notch filter was included, at least our master eq contained that to remove the dreaded "horn quack". DH1A's were paired with HP940 horns. In above example of deltamax the horn is smaller than in my example hence the difference in filters. Measure Your system at first, then add notches to eq out any nastyness. Delay the woofers until phases combine. Hire some experinced guy for a day to help out the tuning. While im quite capable of tuning systems from scratch, I still sometimes hire another set of ears (and measurement set) , bit like doctors' second opinion ;) Cheers, Andy [/QUOTE]
