I have been a lurker here for a while due to doing Stereo, Home Theater, and Multi-Room audio and installations since 2000. I am currently working on a 21 zone distributed audio system and am involved in a brand new company.


I took an interest in Drum and Bass 5 years ago, and as a side project I built a portable sound system specifically built for doing live DJ shows. It has evolved from a pile of direct radiating car subs and various amps, into a legitimate sound system, while on a very modest budget. Below is a picture history of how the system has progressed. The design goal was 20-20 as flat and loud as possible.


Version 1.0 was just a pile of hifi gear with some subs, it all began here...




Version 2.0 began more of a conversion to pro oriented gear...




Version 3.0 included more subs and even more pro oriented gear...




Version 4.0 featured even more subs, and also more amps...




This is the point where I decided to seek more efficient options, the number of amps used made it impossible to power on a 20A circuit. Through some research I found Billfitzmaurice.com... The rest is a continual cycle up upgrades and builds.

I started by building 8 24" THTs...





Shortly after, I built 2 dual12 tops...




Using these cabs and some creativity I have created a system that runs off of my Explorer, WiSound Mobile. 15 min setup and tear down, great sounding, and all fits in the truck for transport...




I got a pair of used DR290s and converted them in to Kickbins, or DRwiKs:




Here are a few more recent pics of the system in it's various forms and stacks:















Here are a couple of videos from a show I did, that poor camera mic:




Right now I am in the process of gearing up to revamp the subs. I'll be doing 6 more THTs, this time out of birch, the width is pretty undecided but I am leaning towards 18", loaded with Dayton DVCs. I'll end up with 4 DRwiKs and some amp upgrades are in the works.

I'm running a PC controlled Ashly NE880m for processing and Ashly FTX-2001s for amplification. The sources are decks, CD-Js and the mixer.


I have a facebook profile with a ton of pictures not posted here as well:
www.facebook.com/wisounds


I'll try and answer the 2 most common questions I get:


1. Why did you build THTs and not a pro sub?

Because I wanted solid output to 20hz, I understand that that extension results in lower sensitivity, I overcome this with cab count. I had 8 drivers on hand that would work in the THT, so instead of spending $800 on drivers I built the cabs. We also came up with a build process and set of jigs that gets the build down to a couple of hours per cab.


2. Why are the driver covers not on?

The drivers I used are car woofers, and not the most robust ones either. They do a VERY good job, but fall significantly short of the DVC. I took the covers off to monitor the driver status better, it does tweak around the response a bit but that was something I had to deal with. When loaded with DVCs, the covers will go back on.


To conclude, this whole project has been a great learning experience and a lot of fun. I'm taking a break from doing shows for a while so I can get the system actually finished. It will probably be at least a year before I agree to do another show. I'll more than likely limit it to 2 or 3 shows a year if or when I do go back to it.


Well there you have it, a summary of my last 5 years of work.


Hi to maxmercy, myn, dbldare, Passing Interest, Bill, and anyone else from bfm I haven't yet run into over here. Looking forward to seeing how everyone's THTs come out. I think they are a greatly underrated cab, but with the number of people building them the word is surely starting to get out.

If this doesn't prove to people the versatility of the THT I don't know what will. Its been tough getting people to realize how musical the THT is and also the amazing SQ they produce for mere dollars compared to other comparable options. Great writeup and welcome to AVS.

Nice to see you over here - I've followed some of your exploits in a lurking capacity over at the BFM forums

I wouldn't hesitate to use the THT in a pro capacity if I had enough of them, myself. A good design is a good design. I think I would agree about 18" width being the way to go... you'll have multiple boxes to array together, and in pro audio it's good to get as many boxes into one van as you can.

This evolution represents great insight and ingenuity. Maybe you could build cabinets for others.

That is my all-time favorite quote, right there!

You started by building 8 THTs, while most of us struggled with one or two!

You are out of control!
Glad to see you, Wi!

Ver 2.0 I did an outdoor party at a pavillion in a park here in town, I had people come from a pavillion across the river probably 1/4 mile away come over and ask me to turn down the bass. Unfortunately there was only one outlet in the pavilion, but there was an extra 20A breaker in the panel not hooked up to anything. I cut the end off of one of my cords and wired it right into the panel. I have pics of that gig somewhere I need to add.

Ver 3.0 was at an unbelievable afterhours basement party. I played from 2am to 5am, knocked a vase off the mantle in an apartment upstairs and had 150 people jumping in that basement. I'll never forget it. A good friend called it the "HiFi Wi Wall".

Ver 4.0 was a DJ Klever show, and was the first time I had ever heard a dubstep set live. All I could do was chill in front of the subs and listen. It was incredible.


Glad to be here, and glad to see so many people here that I know. Now I have 2 forums to keep up to date on my projects haha

I dug around my hard drive and these are the park party pictures, undeniably the most ghetto my setup has ever been...

DJM-909
1pr Technics 1210M5G
1 Sherbourne 2/150
1 B&K PT3
1 B&K ST2150
1 Crown Straight line two
1 Belles Soundwave 400
1 Belles Soundwave 200
1 Behringer EP2500
2 Box fans

The PT3 acted as the crossover, the straight line two off of the LF out on the PT3 gave me control and distribution of the LF to the sub amps.

Yes there are 4 monitors, yes all of the DJs were happy.

I waited till too late in the day to take the pics as it was starting to get dark.

Cool looking setup, Wi.
Good use of box fans, too.

I will definitely be watching for your next build.
You do some really great work.

Congrats, it looks like a "loud" system.
Was that a B&K in there somewhere?

I had a B&K PT3 and B&K ST-2140 in rotation for a while. The PT3 was my crossover and master gain.

Next phase is TBD after I beat up the DVC for a bit.

If all goes well I'm looking at 6 18" THT.

I'll say it again - finally a pro sound guy who knows bass does not end at 40Hz. That's a sick setup man, now if only dubstep was more popular here...

Well, it is amazing how projects take on a life of their own sometimes.

The initial summary I wrote of future plans/builds got turned on its head.

I can't reveal much yet because it is still way up in the air from a design standpoint and is subject to change, but let's just say it is very exciting.


Methinks there shall be some very interesting build threads over the next couple of months. Granted they will be a bit more pro oriented than home, but I think we can deal with that.

If you feel like taking on a complex build we have some plans in the works for a bandpass/horn hybrid sub using a pair of TD18H's. With proper power a singele dual 18 cabinet will get you upwards of 140dB down to the corner point.

Of course there are more traditional options too like the single vented 18 cabinets Elite Audio is using. Here's a picture of the full setup next to an EV Xarray system when we were playing around a few sundays ago.



They've done many national acts with this system, mostly rock/metal shows. They're doing Papa Roach this tuesday night.

If you need any help with plans, let me know.

Big pile of speakers, gotta love that!


The most important variable in considering using a cab design is Fc. 20hz is a must for my music.

not playing fair...how can you make such a claim without saying what the corner point is? ;-)

Hard to find a 20hz Fc cab, much less one that gets you to 140db with anything less than several.

Gotta love DIY

hey wi...love your stuff and have enjoyed reading your posts over time. my comment was in response to john j.'s post. i've been farting around with horn designs for a while, and to hit 140db at the corner (sans power compression)would require a 100db 1w1m system powered by 10,000 watts. i can hit 100db 1w1m at 35db in a 844 liter cab with an 18", but i'm not sure that i'd put 10kw into it!

That is sooo awesome. I'd love to have just a fraction of that gear. Although having it all would be even more awesome.

My Dual 18" LLT subs 120dB down to 10hz

I love the MTM waveguides in the middle (top) of the stacks.

looks like the 18sound waveguide and two TD15Ms!!!
