I knew that it worked I was just alarmed at the voltage it took to get to 20mm like the 152. The 152 takes less to get to 20mm compared to the 9601 21".

Don't forget that the RE of those 2 drivers is much different.

Luke,

can you post a video of the sub moving. I'd love to see this monster sub dancing along the floor.

The othorn is an incredible sub. Here in austin we have several large dance rigs. 5 or 6 big "bassmaxx" ones and a Funktion one at various clubs. Bassmaxx HQ is here also, they make really nice giant dual 18" reflex bins. All that is great for what it is, but I would take the othorn(s) any day over a reflex bin. I instantly fell in love with the tapped horn/quarterwave design. The output is massive, just like a reflex bin, but the distortion levels seem to be much much lower. The extension is effortlessly low. Everyone who hears them falls in love with them. You cant really get an idea of it until you hear one. We have only made two, but I want lots more. Hey BTW Josh ricci!!! Clear out your inboxes!!!! :-) here is a poor quality video for now. The rattling sound the the stage I didnt have alot of time to set em up and record. They gain at least 10db in "cool look" points.

Hey man I'm glad you like the subs. If you add another 2 someday I think you will really start having some fun.

I intentionally keep my in boxes full at a couple of forums because I don't frequent them much anymore or the inbox limit is too small. I can't even keep up with my PM's from just a couple of sites anyway so any PM's would probably not be answered.

Hey Brotha!! Ya I really want to build some more, hopefully I can figure out how to go the CNC route for sake of sanity ( are there plans?) . Im playing with various ideas of what a good live sound matching top would be for 2-4 othorns per side. Ive found the QSC pl380 to be a really good match. It cant push a pair of the BC 21-152-4s to the absolute max but it gets fairly close. I've put these things through their paces, and have been loaded in and out of my van like 50 times already. They have done 20-30 small gigs and not even a hiccup with power handling or over excursion. Had em going at a little psy trance gathering (really fast stuff) for 72 hours straight, without much heat buildup at all. I think the slightly less performance of the BC 21" vs the TC sounds 18" is made up for ten fold with the peace of mind gained knowing that the B&Cs aren't gonna suddenly give out.


While I would love to stack them sideways all the time like in that little video, I think it will prove difficult to get those hatch panels quiet without some weight. Im gonna brainstorm that one. Right side up they never make any noise and I have had zero issues with them wanting to move around. I have little black moving blankets they sit on. I saw a pic on the Danley website of that "hardpop" club in mexico. They have one TH on the bottom, upside down, and then another on top of it right side up. This seems pretty clever I hadn't even thought of it, would definitely want four per side when going that route if looking to stack a top on there to avoid tippage.


In my mind I'm kind of dreaming of four othorns with a danley Sh-96ho on top per side.......ugh....that would be heaven. :-)

Hi Ricci, just read through the entire post and love the results that this cab is capable of. I do have a couple of questions about it though. Is there any reason I can't use the B&C 15PZB40 in this cab. It actually models real well in Hornresp. I realize max SPL will be no where near what a good 18 or the 21 will be but I usually have to deal with 120 volt 15 amp service so I will never have enough juice to power amps big enough to power those monster drivers anyway. I have 4 of the drivers and figured it could be a budget start. A 15" adapter into an 18" adapter to fit into the 21" opening. My current bass bin is a single Yorkville TX9s (larger low tuned 2x18 reflex) loaded with the old RCF L18P300's. I assume a pair of Othorns loaded with the 15" B&C's should easily out perform my single cab and 4 should really shine.

2nd, for a very short time I had a set of folded horns of the same dimensions (36x36x24) and it just seemed much harder to maneuver compared to the dimensions of a standard double 18" (24x24x48 typical). Is it possible to refold it into a 24" wide (same) by 48" tall by 27" deep cabinet (retains same total volume)? Starting the horn throat at the bottom with a down firing driver (like Tham 15) and then refolding the rest above might work. I have attempted to refold horns before in the old Google Sketchup but just don't have the skills. Thanks.

I am sure it can be refolded just fine. This has been done with his Ghorn also. I dont think he will have the time to fold it but LTD seems to always be folding and refolding designs.

PLUS I am waiting to hear more about his Palehorn, or possibly labeled by another name, design results.

@ Ricci
Thank you for your time and effort to design a great sub. I am in the process of replacing my current sub
and I would like to build an Othorn. When you have some time, would you please send me a set of plans
to build by.

Thank you for your time and consideration.

Michael

P.S I sent and email to josh@databass.com and it was kicked back to me as non-deliverable.

Hello sir (@Ricci),

I plan to do an Othorn for my next build (my driver is coming on Monday; got a good deal on Amazon for $375!).

You wouldn't happen to be able to provide the autocad file or any cut plans, would you? Also, when adding those interior braces, do you need to compensate at all by increasing the width of the cabinet?

Shouldnt need to adjust anything when building this design. It has already been tested and built by others. So add your braces and keep the same width. if you were design a horn from scratch you THEN would need to account for bracing. BUT it then depends how much bracing your using also. Changing the volume by a few liters wont change the response by much if any at all.

@Blast12345 , did you get a B&C 21SW152 for $375?
Can you share a link if the deal is still on?
Best Amazon price I can find right now is $648.

Thanks,
Jesal

Bummer - it seems the price went back up again; maybe I should have posted on here sooner

For sure! $300 off is what committed me to the build.

The driver showed up today, so hopefully this weekend I can get the cabinet built (or at least a good start). Trying to decide between MDF and Baltic Birch. Roughly how many sheets will this take? 2 or 3?

Looking forward to your detailed build thread with lots of pictures I may building one in near future

Just fyi, the 8ohm version does not measure the same as the 4ohm version.

8ohm is a little different but should be fine.

I would not do MDF. Use BB or at least Arauco ply.

@Scott Simonian
I entered the specs from the 8 ohm into Hornresp and, as Ricci mentioned, the change was marginal (I checked before I made the purchase). I can post a comparison between 4 and 8 ohm tonight if you would like.

And thank you for the reply @Ricci . I'll probably go with BB; I might as well do it right the first time.

I just remember Josh was unhappy with his 8ohm version when he got it. For whatever reason. Less BL or sensitivity or something.

I would very much like to start on the box this weekend. The biggest thing I'm needing is the width (it says 24", but I want to be absolutely sure).

If it is indeed 24 inches, I assume it is [24" - 2 (ply thickness)] for the internal width? I'm assuming so, but, again, I just want to be sure I get the design right.

I have been wanting to make a othorn for years, but would never cosider a 8ohm driver (not that it's a super bad thing).Because to power it with an 8ohm driver you get half the power from the amp. 2000w is fine, but 4000w=happy times for cranking. If the price is the same why not maximize the power of the amp? Does anybody think that the reason the sale price of the 8ohm driver is so low is because it is the 8ohm driver? Do you think the 4ohm driver can be had for the same price on Amazon, if so I think I would purchase one.

If I have been informed correctly, higher ohm drivers have less distortion at higher power capacities. Also, the driver is 2000w rms, 4000 is peak.

Maybe they have less distortion because they have less power. 2000. 4000, 8000w the more the merrier when it comes to these tapped horns like Danley TH118's, as long as you are careful with the volume control. The bass really starts to hit at these higher power levels, so I've read.
