First time I've ever seen the boards "Active Topics" go blank from inactivity since I've been a member here. Tom to the rescue! An enjoyable read I might add. I've always wondered how to get the side off, never thought long enough to think of using a hand saw. I don't think I've seen one i...

HowieZ... Thats who made his with 18's

It has been done though. I'm brain farting on who did it. It was within the past few years. Ahhh! Crap. Think think think. Grrr. Come on! Brain no workie. It'll come to me. Not recommended at all. But in the world of anything's possible, nothing's impossible. And it's DIY, so do what you want. But i...

So, actual dispersion angles can only be done through measurement. However, you can easily calculate the frequency at which beaming starts to occur, which is still useful.

Now wiping coffee of my screen and keyboard. Thanks for the laugh, Seth

What mixer are you using and what is the band typically mixed on?

You have the dimensions. Google (or chatGPT) how to calculate the volume with the dimensions you have.

Nice. Well done! (as usual)

Unless they're digitally produced sine wave bass notes and are actually hotter in the mix than every other sound, the gauge won't give you anything of value other than entertainment and enjoyment of watching it bounce around like a Hooters marathon team. For setting up the limiter, it could be handy...

Looks the same as the BB in my neighborhood with the outer layers slightly thinner than the inner, but not a paper thin cosmetic veneer. However, my eye's aren't the best.

Love the idea. I used Douglas Fir for similar reasons, but ultimately wanted Poplar which was way too expensive. I've seen threads over the years where people built a T39 out of 3/8 ply with good results. Lot's of options to reduce weight. Give it a go and please keep us posted. Thanks for taking on...

A little food for thought: The only reason to ever build a dual loaded cab is if you need to wire the drivers in series to create a 16Ω cab. Otherwise, it is always advisable to build two separate cabs. Dual loaded cabs offer no advantages over two single loaded cabs of half the width. Yet, two sing...

I suppose, if you were able to book a gig somewhere like a high school, church, or sweet sixteen birthday party you might be able to contact a local DJ to do the show. It could be a good opportunity for some of the other local guys to hear your system and maybe they'd call you if they got a gig beyo...

My existing powered mains (QSC k10.1) tend to sound to loud in some spots and not loud enough in others. Depending where these spots are, it could also be a function of comb-filtering. If they're off axis, left and right, dispersion. Anywhere between the speakers, comb-filtering or just plain room ...

The width of the cab/array/drivers has a direct relationship with the off axis response, dispersion. It's the only contributing factor between the the differing dispersion angles of the QSC K12, K10, and K8. It's also why the column arrays (not just Bose) are so popular with karaoke... more of the f...
