3 drivers, ports around 450mm, plays down to 28hz... all theory though

wouldnt you start getting port noise if you put an infra style horn on the x1?

Hi Adam, Im very interested in building a prototype or two,I think if you can get 2-3 db more out of them it's worth a couple of hours building time.Plus the x1's get a little lost looking under my Martins which stick out over the top of them.Would make my rig look sweet!Got plenty of ply, although it aint the best ply, it's free (which is the best ply when your skint!)Are you ever in Exeter?

NEIGHBOURHOOD SOUNDSYSTEM
Infinitely baffled.

not been to exeter for a long time... but that doesn't mean to say I couldn't... its not that far from me...
 
I think it's worth a pop.... looking at the FK1 horn extension there is a throat / mouth to the horn (if you see what I mean).. so I think it might need a bit more design work than just sticking a big triangle on the front... BUT I reckon just trying it with a three bits of ply (stacked like cards).. might give us a clue as to wether its worth bothering...
 
@HBL.. can't see how a horn extension would effect port velocity?
 
Thoughts?

I think the horn is going to dampen the resonance of the port/chamber combination and therefore it may be worth making a slightly underdamped design - also make it easy to change the tunings for the prototype to see how well the concept works for you.
Would using a series tuned setup work? or looking at HBL drawing, maybe port the rear chamber just in front of drivers 1+3?

Heathrow that last design you posted is almost identical to a D&B B2...which seems to work well enough!

Any progress with this folks? Never designed horns before so not sure where to start? - but i'm taken with the idea!

Im not too sure how to go about it, you could model one half of the x1 with a flair at a time and see what works....?

Or get some chip board and try it out! (brace well!)

Without sounding thick i really don't have a clue where to start, building yes ok i can do that, designing hmmmm.... maybe not?

Anyone fancy giving me some pointers? or coming up with a design?
 
Thanks
