Sorry I can't tell you the exact details but I do remember adjusting the time alinement slightly to compensate for the horn length vs. speakers and of course the horn driver level had to be brought down some to match the speakers. The horn drivers are all 16 ohm so they pull less watts from the amp compared to the 8 ohm paper speakers. Yes - the crossover points are progressive - they all go down to 66hz at the bottom but cross lower between horn and speaker from top to bottom. There was 1 dip and 1 peak that were adjusted for the paper speakers and something was done to the horn too. The speakers are rated at around 600 watts rms each and the amps can deliver around 500 watts rms give or take a few depending on how many speakers I hook up at a time. That's roughly 2000 watts per cab with no caps or iron in the way causing issues - THEY ROCK!!! They sit on top of 2 double 18 cabs with the same series of Faital speakers (1000 watters) and they are aux fed by 2 separate Crown Xti6002 amps. So depending on how you add the watts - the total FOH watts are at least 20,000 and maybe 24,000 - 3x2" horns and 9x12" speakers on top with 4x18"s per side. It's a formidable ground stack and it sounds very hi-fi. <span style="font-family: 'Verdana'">8)~<img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f60e.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt="8-)" title="Cool 8-)" data-smilie="6"data-shortname="8-)" />~<img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f60e.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":cool:" title="Cool :cool:" data-smilie="6"data-shortname=":cool:" /></span></span></span></p></blockquote><p></p>
