Waveguides and horns

[rajacat]

They're hoping to get me the information tomorrow about which drivers they like to go with each model. They also have custom drivers and he said the pricing was pretty good.

They can offer DIY kits that come with the 2-way crossover.

He did say he prefers "BMS drivers 4538, 4544, 4550, 4590, 4592, 4594"

Any more info on the custom drivers and crossovers? I'm on the list for the OS 12. Would I just use the same drivers as Geddes? What's exit angle and CD mounting system? I'd like the get the CD with the highest freq. extension. What's the best woofer option?

Thanks,

Roy

Beyma cp385nd + AE Speakers TD12M would be the best CD/woofer combo based on measured performance. Brandon/Augerpro over on HTguide.com would have XO information for that combo but the Vertical CTC might be difference on his box design because he used the QSC HPR152i waveguide to build the XO.

Thanks Doug,

I went to HTguide.com and tried to register to no avail. Hmmm.... perhaps I need to use a local ISP address? yahoo.com doesn't seem to work. I've had no luck with Audiokarma too.

Unfortunately Brandon is using the QSC HPR152i WG so I suspect my situation will be different with the 12"OSWG.

That looks interesting! Looks like you don't need a large waveguide. Just set it on top of the woofer box and connect with a crossover. Of course, I'm still mostly ignorant of speaker/driver design. I got into this quickly and have to study much more to get up to speed.

Would I better off with this or the 12" OSWG? Dipole too? Hmmm...
It seems that this would be very easy to implement.

here is my project of midbass horn, combined hedlund and labhorn idea with over 3,5 m long horn, should go down to 40Hz and what's more important to me will cover 40Hz up to 400 Hz, where JMLC 200 with BMS 4590 will take over. Thank you Jacek Zagaja for inspiration and meritorical help. The horn is curently in production (carpentery) in 2 weeks time should have some pictures and measurements

Driver for Iwata 300

I would love to purchase a mid bass horn for cone driver to go under my iwata 300, anything planned ?

Hello Anthony,
What driver are you using with the Iwata 300 horn? I have some Altec 291-16B. Would they work? If not what driver specifications should I be looking for when choosing a driver for this horn? Any help would be appreciated.
Regards,
David

hello,

I'm using tad 4001, but no doubt that the altec will work.

From data sheet maybe a tweeter will be needed ?

Regards

finally I have decided to start with open back compresion chamber, mainly due tu visual efect. The horn will be about 2,2 m high, JMLC 200 (reduced diameter tu 740 mm) together with driver will be placed in mouth of Bass horn.

 

[fatbattery]

jaskierster is lovely horn. Have you got a thread for it to follow? I take it I long missed out on the mid horns? I still don't get how you build such big horn strong enough not to resonate.

 

[jaskierster]

resonance can be a prolem, this will be a prototype, soon I will start a new thread with my horn - story

 

[fatbattery]

cool I would like to build something similar.

Incredible looking speakers. I hope everyone liked them at the event.

The finish on them looks great and I can't wait to see the waveguides in person.
