Tuba24s in an Outdoor Stadium

[Jayebob]

I recently had the opportunity to use my 4 new Tuba24s to play music at the opening ceremonies of a national junior disabled sporting event. I placed 2 of them in the V configuration on each 40 yard lines facing the grandstand. I evenly spaced my 6 EV SX300s along the same side-line tilted up to evenly cover the entire length of the of the stadium. I don't have V-coupling plates built yet, but they are in the works. I used a Mackie 1400i in subwoofer mode to power the subs to great success. (hi- passed at 35Hz and low passed at 125Hz) I set up my mixer to feed the subs discretely via a post-fader aux send. I don't need popping P's and wind noise (no matter how many windscreens you use!), coming from MY subs. The play-back of the music was outstanding with bass that was clean and pure and, literally, everywhere. Fanfare for the Common Man, The Olympic Fanfare and Summon the Heroes, all from a John Williams album entitled: Summon the Heroes, were heard as they were meant to be, BIG! The tympani and bass drum hits gave me perma-grin, especially when I told the event sound guy from Florida that they were just 10"(HL10C) woofers. It was truly an inspiring beginning to what turned out to be a spectacular event. The info, advice and experience of others in this forum have been invaluable in my decision to build these, and my 4 soon to be finished DR280s. I've not needed subwoofers before in the kind of sound company that I own- a lot of classical and jazz, speakers on sticks kind of thing, but I just about can't go out without them, now!

That's a great review! That driver is truly awesome in the T24 box. It will stay together for ever if you set your voltage levels and limiters. Obviously most people do not as you know, they discontinued production of that speaker. It's been an improvement for me though as bill has already used the oppertunity to tweak his design to work with a couple of cheaper speakers on the market. I believe in the dual 10" version, he has matched performance of the original disign, and lightened it. As a bonus, the 60hz dip doesn't need boosted back up.
Great review. Thanks!

Couldn't you minimize the 60Hz dip with the HL10C by reverse mounting it if I recall. I have 2 Tuba 24s with the HL10Cs normally mounted. 4 would be devastating I would think. Too bad about the HL10Cs. I would like to build a couple more, but alas I will probably sell the current T24s to a small DJ company and build 4 T48s eventually. I have to say for small venues I love the T24s though. It really is nearly unbeatable for size/power/weight in it's class.

. 4 would be devastating I would think.

They are. That's what I had before the t48's. For a band, I prefer the 48's, but miss the size of the 24's. DJ work, tubas.
