I used to summarily recommend LR crossovers (passive or active) because they are -6dB at the crossover frequency and "should" sum to zero at the crossover frequency... or so I thought at the time. Since that time, I learned about phase alignment and all that. In a situation where you have...

yep, I saw the 2nd order and 4th order in the plans, but what type of crossover is it? Or, is it your own brew?

A friend dropped off a dead Headrush speaker. Module is toast and the HF driver is blown. My plan is to turn it into a passive speaker and replace the HF with a spare I have laying around. Finding specs on what driver is in there is not gonn'a happen. So, I'm going with an ASD1000. I need to build a...

The standard for years has always been Steely Dan because it was all recorded so well. Although, probably not enough lows for the DJ stuff nowadays. I've always used the song Texas by Chris Rea.....it's not perfect, but I know the song and it starts out with lows then adds the kick. A little hissy o...

In that case, you'll get no extra inputs without an additional stage box. Acknowledged, my prerogative is not more inputs..its getting more familiarity with this x32 platform standard. If you're using a tablet, phone, or PC as your interface, it's essentially the same, nothing to familiarize yourse...

*Referring to X32 RACK

In that case, you'll get no extra inputs without an additional stage box.

The X32 is the gold standard in the segment for even larger shows in my area..and I do like the fact that it has a small screen attached to it. I'm able to sell my xr18 at almost the same price I bought it for ($500) .and think i can snag a used x32 in the $700 range... Are you considering an X32 o...

Keep the driverack. You need the dedicated crossover and limiting. Even if the mixer could do it all, you would still stand the chance of changing to a scene that doesn't have the proper processing and blow it all up. Not worth the chance. But, I don't think the mixer can do the brickwall limiting y...

Wow.....just wow....

Wow you are making Crazy Fast progress! What did you use to fill in the holes? I used drywall joint compound. I wouldn't recommend it for situations where the cabs get moved around alot, but I've used it on my other home builds and it's fine and really easy to work with. I've used bondo auto body f...

Of course, you're building T30s, so tilting and rolling is gonna' be really hard unless you are 4 feet tall. Have you considered puting 4 casters on the back of the cab surface mounted like the QSC subs?

I used standard casters mounted in the pockets. Use rubber feet on the four bottom corners and attach the casters where the are just above the floor. Tilt back and they roll. Set upright and they are stable.

I applaud you taking on WH10s. I built three of them many years ago - not an easy build with all of the combination miters.

Looks good.

Thank you Bruce, I use foam so I can replace it very easily for mic hygiene. I'm a germaphobe. I also recommend people chew bubble gum while on the mic, then it smells like bubble gum instead of stinky breath, or whatever else they might be consuming. Don't forget music! Good music is also best whe...

Her mic technique is good, but I would like to get her to keep her lips right on the foam.

Unless you are in a 20mph wind, there's no need for the foam. If you're using it because the mic is popping, then the internal windscreen may need to be replaced.
