Waveguides and horns

[Pano]

For those of you wanting 200Hz or lower horns - what do you plan to drive them with? What CD can really play clean that low?
A 250Hz horn is pretty much the practical lower limit. At least for hi-fi.
I'd go for something like that or up to 500Hz. 1.4" throat.

I'd be interested in the 300hz horn.

For those of you wanting 200Hz or lower horns - what do you plan to drive them with? What CD can really play clean that low?

First off, I agree with you on this...

on the other hand.. GOTO and Cogent both make CD drivers in this range. I for one would love to see a modern horn with these for a no holds barred build.

If I could arrange some delivery or even the local pick-up with Dshambala, (I live in Montreal), I would be in for a JMLC 350 horn with a 1.4" throat. I hope that horns come with a predrilled flange.
As I understand one thing is the order for Iawata horns but there is also the cost of shipping and we need to fill at least a palette to get reasonable shipping cost.

Flange can be predrilled, hole at least 1mm wider than screw - you need fine tune center position. GLS (General Logistic System) can send via air a box 50x50x100cm for about $150/5kg, this is an option for Iwata and JMLC-350 but we have to sign agreement with them, otherwise a pallet and freight. Bad news - Autotech is busy with automotive parts and an August is holiday time so real deadline for new horns is September.

New 15" OSWG horn concept for PA, 130dB, 1.4" coax drivers, coverage 50deg. It has much chance to be fabricated soon.

Hi krzys,

That sounds fine. We can work out details perhaps when time comes closer.

Cheers,

[tinitus]

its not to be negative, but depth of your drawing may give a wrong picture of the shape
makes it look more like a long throw horn than OS

anyway
I thought that 15" was supposed to be at the inner circle of the mouth rounding, to make it a 15" waveguide
well, this probably just shows that I know nothing about it

Count me back in for a pair of the Iwata 300/2 inch horns.

Sorry to waffle back and forth. I think I can make the size work and the price may be too good to pass up.

USA, Michigan.

 

[dnewma04]

Where are you in MI, Mike? I'm also in MI, perhaps we can combine our shipments and save on shipping?

 

[MikeR]

Mr. Newman,

I'm in Oxford, Mi. Would be a great idea to combine shipping.

I met you at the AK fest and talked about your unity horns. AKA Dr. Beaker on AudioKarma. How are the unity horns?

How do I add my name to the list for a pair of JMCL200? I'm in New York City.

 

[Frode]

It seems like there is enough interest for a 250/300hz Iwata, how long will it take before the buy can happen?

[jzagaja]

Fabrication in late September. Soon I'll post editable group buy list.
