Tapped horn outdoor

Does a tapped horn works great outside? We want to build a stack of 8 mth 4654 and since most of our raves are outdoor during the summer, I want to make sure its a great choice instead of a folded horn like the Lab horn or SBH.

I have 8 TH's loaded with 18's and a mate of mine also has 8. Surely they are not your average TH, but i think the behavior of TH's will be relatively the same for most designs. We did a test a few weeks ago with 16 TH's outside, and the bass was fenomenal, also from a good distance. It did not drop off like i've seen and heard BR's do. (Although i must admit that being a physics student, I still can't theoretically explain the differences sometimes perceived as throw, which is just a product of source SPL and directivity)

My cbe18s work much better outside than inside!

Fully horn loaded system. Sound rejection to the side was immense, standing 5m in front of the stack or 5m to the side we measured a relative SPL difference of 35dB across the band , A weighted, without any clever processing.  I think you will find 8 MTH4654 pretty capable, just don't expect it will do the same damage as inside when all cabs are placed in a corner. If you have the option however, always go for a central cluster for the bass and get the mids/highs up to proper height in the stereo Left right stacks.

Whow what are those bins? I've just been messing around with some sims not far from that with regards to the "open mouth" rather than the regular th "slot" opening

Hi tv00

Those bins are Teunos' own, little bit smaller version of my Miss Piggy, a 27Hz TH

Edit

I did an outdoor live music gig with my system last week. Did tune the subbass end with Pink Floyd's heartbeat at beginning of a record. As I know it starts from 25Hz.

It really was sufficient with 2 pigs per side for 70 people .

Also they have some sort of directivity, more than equally sized reflex stack.

And to Teun, can you reveal something about your mid cabinets, rough measurements maybe. Looks like 12" drivers. I'm interested as I'm running one or two 12" straight horns per side as needed.

...shame your in the US... im getting rid of my cubo15s
