I finally figured out the subs I was looking for.   They are the EAW BH-800   18" Bent Horn.


Looking for plans for these, anyone please chime in if you have or can locate them.

Thanks!
-Jim

That was probably a good box in its day, but that day has long passed..  Response is not very deep due to the short horn path length and high flare rate.  The "bent" rather than folded horn is to improve the upper end of the response as 250Hz used to be a common crossover point for subs in 3-way systems.

I doubt you will find any "actual" plans, but it should be possible to derive a similar design.

Centauri,  do you think your C-Bin would be a better choice?   I heard 2 of these EAW cabs under some JBL mini-line-arrays and I was very impressed because of its size.

I would like a bin to run 1 on each side of the stage for smaller jobs/bands.

The upper and lower response of both boxes would be similar, however the EAW boxes are a much larger horn and are therefore more efficient and would be the better choice for 1 per side - I usually run a minimum of two of my C-bins per side.

Should I scrap the BH-800 idea all together and go for 2 C-bins, or 2 186's per side as opposed to 1 cabinet?   

I'm still planning a 4 or 8 186 build, as well as at least 1 C-bin to play with and hear.

Thanks,
-Jim

You'd be hard pressed to find an existing popular horn plan that plays well and deep in singles unless you count the 'tapped horn' approach. Then again...

Deadbeat,

Whats a good Tapped horn plan that would allow me to build easily out of cheaper ply or MDF for experiment?

What frequency range are you planning to encompass, and what form factor? There's two main ones - long and thin, like a pencil, and the other is a conventional box.

Looking to go as low as reasonably possible..   40hz?   up to say 150 maybe 200 if possible, but not required.

As far as form, I'd like to do stacks, so stack-able cabs are best.     But the long and thin sound interesting as well.

40-150-200hz...

Not long and thin...

I'll see what there is:

60-250hz flat:

If you can make a plan from hornresp inputs (quite easy, if you want I can show you how!), this is a good one from 50-nearly 200

Apache H15, 40-200 apparently:

Deadbeat,

Interesting!    The Apache H15 is looking nifty,  I'll see if we can mock one up here this week sometime to see what it does.

I just purchased a stack of amps, so we're taking it easy for a little then on to building a series of cabs for next spring/summer.

give it a good measure for all our sakes as well please!

All you need is a soundcard, a mic, and ARTA:

Wait up, i've got an eminence tapped horn with very similar performance somewhere from djk, wait a mo.

This one is done on Akabak but he also provides a picture on how to turn the numbers into plans.

How come I never see any 18" tapped horns.

The TH likes a woofer Fs to be higher than the Fc of the horn.
 
Most 18s have a very low Fs, so a TH would have to be tuned very low for most 18s.
 
I have posted TH designs for a 30hz Eighteen Sound 18", a 35hz Selenium 18,  and a 40hz Kilomax 18.
 
A bastardized hog-scoop/EV T18/TH kind of thing with an Eminence 18 shows promise for making a LOT of noise.

I hate to revive this... But I was just curious about my request.   Does anyone have or, have spotted the BH-800 plans?


Posted By: NLIS5828

Hmmmm, I beg to differ on the post saying they are past their due date. I have a pair of BH800's i just acquired, and they kick! The frequency response range is quite wide actually. I believe it gets down to 33 Hz. The only thing about these cabinets is that they are very bulky, and they only put out 4000 watts peak, when you can get JBL double 18s which are more compact and put out 6400 watts. All in all I like them so far. Im running them with a QSC PLX3402.

BTW i still have the original RCF drivers in my pair of them and I just had them reconed. Now that mackie bought out EAW they've been putting doggy pootier components inside their cabinets. If the price is right i would consider selling these beasts lol let me know if anyone is interested im in massachusetts. I've been thinking of getting some JBL double 18's.

The "C-bin" is http://www.centauriaudio.com.au/diy/cbin.html - this - an old design now, but similar in concept to the BH800 although using two 15" drivers - more compact but not as efficient, and covers about the same range.

If you want an 18" tapped horn then google the Otthorn.

When I google Otthorn,....I get German lawnmower newspaper ads.
This post was originally to do with the BH-800, and had strayed off topic, and I see my posting of a pic of IT failed to bring it back on topic lol....

LOLLOLLOL

So I assume the greyish bit is a conical expansion from a narrow slot to the full width of the cab.  Seems like an awful lot of unused volume in this design, but I bet it sounds nice.

Date Posted: 05 August 2013 at 12:26am
Yeah, looking up in the cab the 'greyish bit' is like looking into a MT121, except obviously its an 18.

The black is expandable boat floation foam. The grey  is the expanding 1st flare. The throat ia approx 11 x 11 inchs. The bottom of the 1st flare is 11 x 28 inchs.  Boat foam fills the sealed in side of the 1st flare. When used 4 to 6 a side in a med club the kick and bass is awesome. In real life sounds deeper than the specs. One per side is not that good. For portable use needs truck with lift gate and NO stairs at the club. VECTORSONICS
