- Testing my newly built TH-18 tapped horn subwoofers outside. Gear is as follows:
-2x TH-18 tapped horns with B&C SW115 4ohm woofers
-2x KV2 ESD12 passive mains
-Crown Itech 6000 for subs (2 x 3000w at 4ohms)
-Crown Itech 4000 for mains (2 x 2000w at 4ohms)
Mains are high passed at 90hz 24db/octave butterworth, subs low passed at 80hz 24db/oct butterworth and high passed the same at 28hz, 5.8ms delay on mains, NO EQ!
This is an extremely powerful system with the tightest and most musical bass I've ever heard outside! The KV2's sound very smooth and clear. The subs -3dB point is about 36hz according to my measurements.
The track playing is Jim Keltner - Drum Improvisation. The SPL meter is positioned 5m away. You can see peaks of 116dBC on the kick drum hits which would be approx 130dB at 1m! My phone's mic is distorting. Could definitely feel a punch in the chest and met a neighbour a few houses away!
Thanks to Martin/Xoc1 and the others on diyaudio.com for designing this kickass PA sub! - เพลง
Very nice setup BTW!
nice work man
Nice!
Thxz for your reply Wish I had your set up thxz
More vids on the settup please :-)
+Javon hall I just uploaded a new video of these!
Hi Great video its been a few years do you still use these and did you build the originals or the newer cone corrected version?
I certainly do still use them but don't do gigs these days, they're setup at home in my lounge room as crazy DJ monitors! Yep my ones have DJIM's cone correction but not the longer horn path like in the even newer version.
@@eggchen18 Awesome thank you for the info! I'm starting a 4 cab build!
How well does the TH18 handle the 31hz low note in Diplo's Revolution? I have been looking at this design for a while and was concerned about the approx 40hz roll off. Thanks
+David Duff I will have to test out that track next time I have them setup outdoors. I did some REW measurements and the -3dB point is 36hz. Do you have some low playing subs that make that track shine?
m.th-cam.com/video/yMzLJDwGq9k/w-d-xo.html
tell me if it is necessary to reverse the phase on this subwoofer due to the fact that the speaker is located with a magnet outside
But why did you decide for the 15 inch b&c instead of the 18 inch?
Very interesting horn, the 18nlw9601 by 18sound would make a beast out of it ...
Im really thinking about building a pair.. do you really power EACH of them with 3000 watts?!
I used B&C 18SW115 which is the 18inch version. Didn't type the model number properly! Yes my I-tech amp puts out 3000w RMS to each sub but they are so efficient that they would maybe only see 1000w on peaks when cranking them! You should definitely build a pair you won't be disappointed!
@@eggchen18 Do you think you could get away with an amp that has 2k-2.k peak output at 4ohms per sub? Sick build appreciate any insight you have!
@@chasepe5762 What specific model amp is it? RMS output is more important than peak. Also the answer to this would heavily depend on what genre of music you'd be mainly playing.
Hey i saw ur post at diyAudio. And i've been thinking about building 2 of these TH-18 atleast 1 to start of with. How do these sound like inside. Thinking about having them in my house lol
I had them setup in my lounge room for a while in stereo and they sounded beautiful even at low volume! If you have the space go for it! However bass never sounds as good indoors so depending on the dimensions of your room and listening position you will get peaks and nulls in the bass..
What country are you in? I'm looking to build some horn-based subwoofers.
Beast system but tell me whats the benefits of a Foldee Horn sub vs a Front loaded or typical sub im asking cuz i have four 15 inch woofers i want to put in two double 15 boxes but dont know if i want to build a dual folded horn enclosure or a dual front loaded enclosure id like to know the benefits etc. Also im a Dj but have another two 15's ready for that gig so yeah let me know
This is a tapped horn which is a bit different to a folded horn (tapped horn doesn't have a sealed back chamber). Benefits of a tapped horn are +6dB sensitivity and output over a front loaded reflex, less amplifier power required and better phase response (if it's a good design like this one). One of these TH-18's has more output than TWO typical manufacturer 2 x 18inch front loaded reflex cabs!
Due to the extreme stress placed on the cone, you can't just stick any woofer into a horn loaded system - it needs to have specific parameters (such as a strong motor and stiff cone) to enable it to work well. So it depends on the parameters of the woofers you have. Check out the subwoofer section on the diyaudio.com forums
4 dislikes are from your neighbors right?
Funny you say that as I was using them while polishing my car recently and this lady from 3 houses away complained :D
@@eggchen18 only 3 houses
Nagkita pa din tayo dito Sir. Hahaha.
How much power were you sending into the subs?
+Douglass Berry 3000w each from a Crown Itech 6000
+eggchen18 So the amp was running at full tilt in this video? If so, these cab designs are massively unimpressive, as a single one should be able to do well over 130db at 1m. A pair of simple, EV ETX-18SP's can do 130db at 1m.
+Alex Berry They are very efficient at about 104dB 1w/1m each so they were massively overpowered. So they were probably only receiving ~100w each during this video.
eggchen18 That's exactly what I wanted to know! And is the best news I've heard all day! Thanks! Also, I think you meant to say massively underpowered, cause sending 100 watts into one of those B&C drivers is certainly not overpowering it, lol.
Where did you get the perforated steal for the front grill?

thanks alot...
Thxz for time 11.2 how long is the horn in side th118 and I betitsoundreally good
The horn path is about 3.0m. This is the best subwoofer I've ever heard, it's very musical and has a BIG sound!
@@eggchen18 Hello! Can you tell me, what type of wood you used to build this subs?
And thickness of plates?
and last my question.
I have noticed, that not always subs play good outside, diference goes back to 400 percent. Its normaly? in good acoustic day, bass can be verry big, and quality. You can have this too? thanks :)
@@basserex4991 18mm 13 ply baltic birch. Which plates, the ones in front of the cone?
Hey, sorry to ask after 8 years haha, im building some and i wonder if it is good enough to send 2 x 1600w into 2 x B&C 18SW100, what do you think ?
Depends on what tyoe of music and how many ohms that 2x 1600w is. Also I highly recommend saving more for the 18SW115 instead as it has more xmax, higher BL and a slightly heavier cone which will be a lot more robust in a tapped horn like the TH18!
@@eggchen18 i want to send 2 x 1600w 8 ohms in 2x B&C 18sw100 for every types of music, also for noise exhibiton, pretty open to listen everything, yes the sw115 for sure better, but how if i just send 2 x 1600w in 18sw115 ?
2 x 1600w 8ohms is plenty and about the same as the 2 x 3000w 4ohms I was using on my pair with 18SW115. If you're playing EDM with heavy bass all night then you must set proper long term RMS limiters otherwise they can overheat!@@hugochevillon8701
@@eggchen18 thanks very much ! I was worrying not being sure before ordering my stuff haha, i dont know very much yet about this kind of stuff, thanks from France.
Dear friend, I am hesitating between othorn or TH18 with the 18SW115 controller
Hi Bryan, the othorn is heavier and more difficult to build but plays lower (-3db point of 30hz vs the TH18 at 36hz). What sort of music will you be playing mainly? The TH18 still sounds fantastic with EDM but the othorn will play those deeper EDM bass notes with more authority.
eggchen18 Dear friend, thank you very much for helping me and responding. I usually play neurofunk, dubstep and drum and bass for raves (my competition uses SBH). For now I only have a proline 3000 amplifier for this purpose. What worries me is that othorn has less sensitivity than Th18. A hug
Bryan Rueda Cortes I read in the othorn discussion that it needs a very powerful amp to get the most out of it (4000w RMS). The type of music you are playing would benefit from having true 30hz extension - the crowd would love it! But if money is an issue the Th18 with the SW115 is still a beast!
eggchen18 Thank you very much again for your help, I will try to get money first for an amplifier fp14000 clone for example and if I can not pay then I build Th18, thank you very much.
eggchen18 One last question, in my country Spain, it is difficult to get b & c, I can get 18sound, specifically model 18NLW9601, I understand that this is valid for Th18 and othorn and the parameters are very equivalent but I do not know if it will hold dubstep for long times
Use kv2 ESP 2000 amplifier?
Nope, I use Crown Itech 4000 for the KV2's.
Kv2 ex2.5mk2 active sub woofer more bass more kick.
U can try
What the time Aline meant at about 7m|s
With a high pass of 100hz on main speakers and a low pass of 80hz on the subs 11.2ms of delay to the mains aligned the phase traces according to SMAART.
what is the tittle of this music???
Jim Keltner - Drum Improv
song name
tosa sebastian remix Jim Keltner - Drum Improv
Test the bass
Sounds 'woofy', more mids and HF will make it sound punchier.
Yeah I think I need more tuning work - the walls of the house screw up the 100-180hz area but even with this they felt punchy! The original recording is also a bit on the woofy side if you listen to it with headphones. The distortion from my phone's mic doesn't do it justice either!
eggchen18 Looks like you done good.

add the usual hashtag in front of that (why won't they let you use a direct link?).
That system does 122dB at 20 foot, which calculated back to 138dB at 1M. Power was one channel of the CA6, 400W/8Ω into a pair of JBL 2445, One channel of the CA9, 1000W/2Ω into the horn-loaded 12's for mids, and the other channel of the CA9, 1000W/2Ω into the PPSL 31hz tuned woofers. The PPSL are H24" x W36" x D30", about the same as your TH18.
TOUHOU 18?????????
