1x18 Horn

Just built and tested a single 18 horn with a new driver on the market, with what I feel is unprecedented success. I found the driver by accident and couldn't believe the results I obtained at design stage so had to make it!. Tested against an 1850 horn loaded with Void V1000. Better SPL at lower power input levels. Good sound andlower bottom end. 40 hz.
I'll get some pics uploaded whenI can. The cost of the driver is less than half the Void, and after hammering the driver for a few weeks with peak levels above +/- 140 volts, (oscilloscope on amp leads) I can say the driver is reasonably rugged. I haven't mentioned the driver manufacturer yet, since I know everyone will have a very good laugh, but I think this goes to prove you can always find one rose in a manure heap if you look long enough and don't mind the smell!.The cabinet takes less than 2 sheets of ply to make, and the driver is far lighter than the void. Cost of components including driver, handles, speakons etc. would be in the region of £230-00p per cabinet, and 2 people can comfortably liftit!.
Size is slightly larger than 1850at 1075x750x636with the mouth at the top end, if compared to the 1850. More details to come when time and patience is available.

sounds fantastic, more info & pics please

Pics and driver name now!

Its not another celestion, is it?[img]smileys/smiley1.gif[/img]

have you got anything against celestion Deadbeat?

[img]smileys/smiley36.gif[/img] Of course not! I use mostly celestion and P Audio actually (yeah, i'm cheap). They certainly are good value for money, and i've only ever had to recone one, when some idiot played around with a signal generator and a prototype design. I was just guessing the speaker make based on the other horn's speaker. Looking forward to the pics and plots and plans.

Funny, I've blown a few in my time with a sig-genset to the wrong frequency, not supposed to put 0.1 hz into drivers from a 1000 watt amp!. BBQ anyone? (HDX variety)

idiot: 'Hey, that speaker looks like it can go low. Ever heard of the brown note?'

Me: 'It's a prototype I built earlier and can't go as low as 4hz, which is where the brown note is commonly...No! Don't touch that! @%^#%!!!'

Idiot: ' I'm sorry.'

*Speaker and my head gently fume.

It was one of those BX series ones as well...can't get them anymore...[img]smileys/smiley19.gif[/img][img]smileys/smiley19.gif[/img][img]smileys/smiley19.gif[/img][img]smileys/smiley7.gif[/img]
