You might ask at speakerplans where the designs are hosted. Outside the UK/eurozone those drivers are $$$$ so not many use them.

The 186 should give you higher output, when used with the recommended higher-BL drivers. The 1850 horn was re-tuned to accomodate lower-BL drivers (including Eminence). I fooled around with using it for Omega Pro drivers breifly, but dropped it in favor of something more like the Tuba36 with a 15" instead of an 18. Those old-school horn designs really need the stronger motors.

Ins't not the inverse?
If I remember Rog Mogale made them:
1850 has a bit minus back Vb, made for PD1850 less extension down and more SPL.
1856 has a bit bigger back Vb, made for the 186 goes a bit lower in extension, with a bit minus in SPL.
After Void made a better one called Lonney with a driver like Void18/1000, a mule kick in your face.

Made four mod 1850, with a bit morew back Vb and are very good speakers.
In a stack of four with correct cross could easy do it from 40 to 100Hz very well. Above a bit onky.
Made 2 T36 trying several drivers innit. No way. Nothing down low. HD 15 performs better with less than half the volume of the box. Firing the wood was the better ideia.
Post some photos of the burning beside jbell's ones.
Wayne Parham made some curves of this things performance in a subwoofer shoutout.
Some days after it dissapears from BF site.

Regards,

I'd be more interested in the similarities. Neither one will go below 50 hz. Kind of adequate for PA for bar band old style rock music but not much else.

It will need a steep high pass filter probably around 60 hz, once that's in place it will already be down at least 3 db at 60.

IMO basically useless for any type of modern music.

The low knee is around 70 hz. It's already about 5 db down at 50 hz. Add a 60 hz highpass filter and it will be 5 db down at 60 hz.

Add 3 more (stack of 4) and it will be 12 db louder and it will go about 2 hz lower.

Like I said, useless for any type of modern music. Very loud but it's not a subwoofer. I'd call it a midbass horn.

And 956mm x 636mm x 750mm isn't really small either....
(38" x 25" x 29.5")

Pretty sure a Danley TH-118 betters that in the same size format.... Well slightly different, but very similar. (40x22.5x28.5")

all your posts are very interesting, and i have tried asking on speaker plans and no one seems to want to reply! but this forum seems a lot nicer

I have also tried contacting the designer but im guessing these are old plans!!!

So you think that folded horns would be a bad idea for a DJ playing house and dubstep ?

Any suggestions ?
