Good job Mark! The boxes look great. I like your comparison to the OS's. Have you used them together at an event yet?
For my use I find single 18's offer the most flexibility. I've got 12 in the inventory now.
What is it about subs, when I see someone do a successful DIY project I have the urge to start making saw dust even though that's the last thing I need more of right now.
Thank you Don ! Good to hear from you.
Yes, I used them at a VT graduation party this weekend with a single JTR 3TX. (PM60 would have been overkill
)
I had both the subs on one channel of a PL380 and the 3TX on the other. It all sounded super till it came time to really crank VT's fight song, Enter Sandman.
Still sounded super...just wished I had 4 subs....but a 3TX is good for a pair of OS's, so of course I needed more subs...
Hey your urge to build, and comment about 12 in inventory, are about to get me making more sawdust
edit : I realized you were probably asking if I have used the diy 18"s with the OS, on an event yet....
Not yet for an event, but a band manager came by yesterday afternoon to check out what I can offer...
Since I had the subs already setup in the driveway for testing, I just threw a top on the sub combo betting it would work as well at volume, as in testing.
If it didn't deliver at volume I was going to pull out another OS.
But happily, it worked and sounded, excellent.
The more I think about, the more i get convinced combining different type subs shouldn't be that hard.....the wave lengths are huge.....if anything can be coupled it ought to be subs..
I mean, if they are located together, and the exact same HPF and LPF types, orders, and frequencies, are used on all the subs so that there isn't any electrical crossover phase difference, well....
.....all we have left to align is the natural phase difference of the sub type, and maybe some physical distance offset.
It shouldn't take that much FIR, if all we're trying to align is the natural phase difference between sub types. I just can't see latency being a problem.
Maybe it's a cheap way to couple existing sub inventory across different type boxes ....
