Kicker 9/11 truck "28 and 45hz we were hitting over 140dB in room with 2.8kw"

kryptonitewhite · Aug 20, 2011

My idea, 25Hz tapped horn using Kicker CVXs, was stolen by Kicker, by Deon screen name dB-Kicker. I didn't do any of this design work or build, it was just an idea, but an idea shared between 2 men in private messages. Since my private message turned into a very public build, I took it upon myself to do the same...share private message information.

I made a comment/reply in his thread about it, he ignored it and sent me 3 PMs confirming guilt. I gave him a day to reply, then started my own thread. It was ignored, then deleted, so here you go!

Re: CVX vs Solo X

--------------------------------------------------------------------------------

More so. We broke the building with them. Had groups of 5 and 8 and 10 people at a time standing - trying to speak, making their hair stand up, pressurizing the room with Fun Stuff. I won't post this - but between 28 and 45hz we were hitting over 140dB in room with 2.8kw. This was a BIG room. Room gain helped of course as did using the rooms constructive interference modes (corners). Most of the attendee's had never ever experienced bass that deep that loud... And this wasn't with auto cabin gain Lotta fun.....

Solo X's have suspensions too stiff, and motors just a little too strong to make for happy TH tuning. They are designed for one thing - and one thing only.

It looks like I need to respond to this directly.

Apologies for everyone here under this thread for having to hear someone air his personal vendetta against me on a forum dedicated to TH builds.

Jordan,

I have not responded to your accusations for several reasons, the first and by far the most important of which is:

April 22, 2011: My father was diagnosed with Stage 4 Lung cancer– he now has less than a few months left to live.. I stopped talking to almost anybody not my immediate family, or closest friends then. This would be directly in the middle of you starting with this tirade.

Second:
Your accusations and ensuing onslaught deriding me for ‘stealing your idea’ have no basis in reality. You are not the first person who ever thought of dropping a TH in a vehicle. Search the web – there are dozens of threads where people have been doing exactly that since the first time we figured out how to model TH’s.

Your questions to me relating to the usefulness of using multiple of Solo X’s loading a TH in your VAN, firing them forward at an SPL microphone from the rear of the van’s insides are in no way shape or form even relative to the project you have been up in arms about.

The TH sub in the First Responder sits in the truck bed and fires into the surrounding atmosphere. It isn’t loaded anywhere in to the vehicle. It is used as an out door sound reinforcement woofer – PA style.

Before that, and before you ever asked me about TH’s in your Van, some history, all of which is documented…

2007: My first TH discussion with the inventor of Tapped Horns (also the TH patent applicant) and my friend Thomas Danley regarding TH and TH woofer design theory dates to BEFORE HIS RELEASE OF THE DTS 10 Super Spud!

Tom approached me while I worked for TC Sounds regarding the suitability of TCS 3k woofers – or a new driver design suitable for his TH’s – while he was designing either the MatterHorn, or a TH subwoofer he was commissioned by someone in Marin county CA (I think) to build. Or maybe the Bay area... Thomas D can correct the time frame and specifics I am sure.

November 3 2008: My first e-mail discussion regarding a large outdoor truck bed 25hz Horn subwoofers began here at work, with a request from our Venezuelan distributor for a high SPL sub design for use in truck beds of their outdoor crowd competition vehicles. I committed to our trainers to design one when I had could. I was also asked to design PA subwoofers for Ted Nugent’s band – which would be the same type of 25hz sound reinforcement type sub.

2009: Mike documented his first quad-driver tapped horn over at DIYAudio.com in the "collaborative thread". The layout is inverted, but the design concept is essentially the same as what he folded up for the "First Responder" project.

Dec 6 2009: after Tom shared his DTS-10 Super Spud drawings with me –then helped me redesign the Super DTS subwoofer for my personal use to accommodate our CVX 12 drivers. I had planned to use a variation of the DTS-10 as my home ULF – we traded models, driver details, and drawings. We also discussed a Quad variant of it at that time, I have cad models traded with him then showing this.

July 07 2010: I sent an email to William Cowan requesting information on TH’s. Directly after, I decided to test the idea of TH use in vehicles with a variant of Erik Forkers (Volveter) 6.5” 30hz TB. I built this as a proof of concept TH test bed exploring TH applications in vehicles. I hadn’t heard them yet, and needed a small unit to play with.

My lab tech and I took this 6.5” 28hz TB TH and installed it in his truck, then my personal vehicle. That little 6.5” driver hit 114dB @ 22hz with no effort whatsoever in my car – moving the package shelf up and down over an inch. I call that digging deeeeeep for a 6.5. This was before I met Mike.

After experience with this little TH my desire for a TH used as ULF in my own home to replace my prior line up of theBeast-MK’s 1 through IV grew strong. For the record, the first of theBeast subs were shown at a DIY audio meet in SoCal in 1997. Enter Mike.

July 8’th 2010: My first discussion with Mike P. about TH Folding began with us working on various TH folds, including theHouseWrecker – and other higher tuned crazy subwoofer enclosure ideas. Including the possibility of doing a variant suitable to use for a truck bed for our Venezuelan customers. We also discussed the suitability of TH’s to enclosed vehicles with variations for SPL vehicle duty.

July 27, 2010: Joshua H. from NASA (yes the Aerospace corporation) e-mailed me with questions regarding using our Solo X’s in an acoustic chamber to stress test equipment that will be used on the mobile launcher at Kennedy Space Center. The chamber utilizes (4) Solo X 18” drivers in a sealed configuration being powered by (4) 14Kwatt amplifiers. After speaking with Joshua, Mike P and I discussed the suitability, or in-suitability of using a TH variation with our Solo X’s for the NASA project.

August 2 2010: directly after Joshua’s e-mail discussing NASA’s acoustic stress chamber, I was approached by one of our trainers with a side project to help with a sub that needed to work for the 9-11 tribute parade truck. He needed a subwoofer that would get DOWN and play LOUD without the benefit of CABIN GAIN, and the truck bed subwoofer was once again re-initiated, in Ernest this time.

August 12 2010: My Lab tech had his last day, he moved to a new career opportunity working in nuclear power plants.. Remember - He and I had built a variation of Volveter’s TB TH – tuned to 28hz – just to show people what you could do with a tiny driver and a TH sub in a vehicle before he ever left.

December 6 2010: I traded Mike’s and my idea’s for TH designs with Tom Danley – sending renders, models, HR txt data, and CAD files letting him know what I was naming it, getting his input, making sure he didn’t have issues with the purpose – etc..

The common thread here is a timeline of events playing with subs, horn sub idea’s, including TH’s for personal, and recreational use. This timeline involves friends building TH’s in homes and putting them in vehicles prior to your first communication with me.

If I recollect that was around the beginning of April 2011 this year. Since it wasn’t an E-mail – I can’t date it, though you ripped the whole conversation, it’s still under a YouTube video.

So let me know if I have this right.
A sound reinforcement subwoofer we started working ideas up for in 2009 which stemmed from a request to design an outdoor truck bed horn subwoofer for the Venezuelan market back in 2008, that over time evolved into a truck bed TH sub collaboration with Mike; which was a variation of a project he displayed online in 2009 and is now used for a commemorative tribute vehicle I somehow stole from you deep into 2011?!?!? This was your personal intellectual property?

My employer donated everything to that project without any form of recognition for the company, or the personnel involved. Myself, Mike, John, and Gene all donated our time and energy for free.

I dropped a TH into my own car more than a year before you asked about Solo-X’s suitability to a SPL vehicle TH in your Van. The project has NOTHING to do with SPL vehicles – it is a sound reinforcement system to broadcast sound to an external audience.

Not one single person or company or sponsor are identified on that truck anywhere an audience can see anything out of respect for the families, we were asked to help for free and we gave our help gladly! One of my own friends was in the second tower as it started coming down – he’s a New York city police officer. He barely got out alive with 3 fire fighters and 3 civilians he was escorting.

You asked me about the Solo-X’s would work for an SPL vehicle (your own VAN), Jordan. My abrupt cessation of communication with you had nothing to do with you – or even the world of subwoofers. I stopped talking to you because I was on an airplane to be beside my father some 2,000 miles away, fearful that I would never get to see him again.

For that I have the privilege of being reamed by you, having you make YouTube Video’s disclosing my PERSONAL Face Book profile and private IM’s with you, then I have the honor of having you rip me across the internet, cross posting hundreds threads, dropping links sharing private conversations, taking things I communicate with you out of context and claiming I stole your intellectual property rights for our vendetta.

Let me say this Jordan. And I fully realize you’ll more than likely rip another enormous internet armchair warrior shred thread against me, but I will say it.

You owe more than Mike an apology.

Deon, I apologize to you as well. When I received 3 PMs after my first comment, I felt it was to cover up and avoid reponding directly to my implication. I was very wrong, and I am sorry. I will cross post this to the other threads to admit my wrongs everywhere else as well.
