You don't specify which way round you mean, whether side by side like Vitor's or end to end like I built mine (like a funktion bin).

However which ever way you want to build them, they are simply 2 HD15's next to each other - just leave out one of the sides (or ends). The plan is the same as a single HD15...

I've been wondering since seeing yours Dom whether there's anything to be gained by shaping the piece of wood between the 2 horns to help them to couple better. I know that Turbo and FK1 have a cutout but i wonder what difference it makes?

We wondered that as well when we were building them.

Unfortunately our research and development budget is ever so slightly less than either Turbosound or Funktion so we went for the "if it aint bust dont fix it" approach in that we knew they worked as singles so they must work as doubles with a full dividing section. On top of that it's somewhere to attach a grill...

Thanks for your response, but what the difference between the 2 types of enclosures, Vitor's and you, performances ?

Sorry for my bad english, i am French !!!!!

Probably no difference. It's more a preference on dimensions. Long and thin or short and fat and whether you want to use them in pairs and how they're oriented

Since you really need to use at least four singles. it really doesn't matter which way round you do it.... Funktion stylee works better for a stack of 6 though IMO
