  1. It will see 40+ I believe its only partially a high xmax sub its low end monster that can handle tons of power and efficient. More cone control towards peak xmax where other subs start to lose cone control. Xmax is what these can be modded for though
  2. Stevil I've been waiting 13 months for results from these lol. I never heard these in his system just 22-27-32 hz burps at half volume which was doing shirt tricks violently. Will needs to get in here and comment. I couldn't make it to the show myself or I would have posted Vid immediately. The xmax is 28mm one way but actual stroke side view is impressive. Definitely larger spiders needed
  3. Yes Perry thats the basics. If this gets off the ground, they will eventually look alot more appealing like this picture
  4. PM Will or me I will be building the smaller model in 10"-15" 1000rms. We have a machinist, and parts all ready to go. The big ones, 3500-5000rms if we actually decide to build these will have a month build time due to machining process and getting the motors shipped. The biggest issue is weight. The small ones alone will be 45lbs and use 2" coils. the 3" coil model starts at about 80lbs, and we have a model we will be messing with soon that is in the 110-120lbs each subwoofer- Not really a high demand woofer. The ones he has are 80/85lbs each
  5. Wont get into details other than, think of a See Saw thats the basic idea of it. Any further info and I gotta kill you
  6. Whoever says there is patents being stepped on is wrong. These have been in the works in multiple designs since 2006. These were built 13 months ago for last years Autorama, but Will couldn't make it, so these were put away in the corner of the garage for a whole year, dust, spiders etc. The last 3 years we have tried multiple configurations to stay away from other patents. Even from the design shown, there are alot of improvements. This was the largest paired prototypes we built, and were not meant to last longer than some testing and to get some T/S and out put numbers, rebuild -redesign/start over again. Will being the bass head he is, loving big houses, big dogs, big subs, big amps, loving low numbers and high power, this concept going extreme in his ride matched his whole fortay- so perfect match! Bringing them to Autorama was to stir some shit and even get some pre orders if anyone is interested. The extreme model is going to be made in all aluminum basket, some lighter and stronger parts. The benefits of this design are a Dual linear Drive design, meaning there is two separate coils. One goes one way, one goes the other- like the old tree saws of the 1800s early 1900s two guys pushing and pulling on a 10ft saw to cut a massive redwood down. This helps with controlling motor force alot. When a typical motor/coil design loses motor strength at peak excursion and even gets sloppy, this sub has full control. Benefits are accurate brutal low end bass. Another benefit which may be obvious is cooling.The coils radiate heat away from the winding's That flower piece on the back serves two purposes, one happens to be a heat sink. So power handling is increased quite a bit After 6-7 years of being in the garage proto testing, it would be nice to get this design off and running if there is interest
  7. Great install Steve. When I swung by the other day you looked hella busy with that stuff drying, I wish I got to take a good look at the F but was just delivering a $20k pressure washer for my work lol. Oh well, another time. Bad ass wiring job from the batteries to the trunk lid man
  8. Robnie, I think your definitely adding great info. One problem I have is say T-line or Transmission line in place of Quarter-wave Pipe. A quarter-wave pipe, what this thread is originally based on is the "T lines for Dummies " of quarter-wave/tline design. (The Dummies part is not making fun of anyone, just in case there is no books in your country "For Dummies") I have noticed in Quarter-wave pipes, they are way more flexible with woofer style, no need to taper like the design your showing. I tried tapering your style before, and its just not for me. Its to complicated for most even.
  9. Well, it had good results when I built them. I just didnt have the wood to do a larger design with a lower tuning. I really want to do a 40hz or lower on a 15" or larger subwoofer
  10. Also, I guess if anyone wants to try the Passive design, I can build up some tune-able Radiators 10" - 18"
  11. Because of another thread, I been getting a lot of emails and PMs here. I haven't updated or done any build logs in the longest because I been to stuck on speaker repair and sales. Also, I have had constant back issues, sciatic nerves, disc issues, and no medical to fix me.. Usually about once a year I do something wrong, like tie my shoe, or pick something up, and bamm, bed bound for 2-3 weeks. So All I can do is stray away from heavy subs and heavy box building. There are some box designs I wanted to share with you guys that I haven't been able to test thoroughly enough yet. I wanted to see you guys try and take the task on. There are a lot of hobbyists on this site, and especially in this thread, so I'am sure I will get lots of takers on the designs. I have always took the normal Tline and tweaked it. Why go through the math and programs not readily available to build something that people think are so damn complicated, when there is a simple approach to them, that DOES work. Thats why this thread is here. Anyways, here are two for now. First is a M-Line or M horn. similar to some other exotics, but I just never could find anything exactly like it. I have built two before, but one was a mid bass 8" I tuned to about 60-65 hz, the second was a 10" to about 50. I always wanted to do a 30-40hz 15" or 18". This one shown is for a 18" I call it a M design because of the obvious shape. The line starts with a large area like the ending of a horn, the middle pinches to speed up air flow, and it ends exactly the way it started. Iam sure people who have scrap wood or who go to Homedepot for the scrap 55cent bin can do this for cheap to practice with. This second one is much easier, smaller, and is a more musical box. I have built one before with some 8" and used a 10" passive and it worked pretty good. This shown is a 50hz tline, with a 12" active in the beginning of the line, and ends with a 12" tune-able passive radiator. The radiator should be tuned to around 25hz. This should be a easy design to accomplish. The result should be something to play pretty well from 60hz to 20hz in car a 50hz line also has a 25hz 1/8th wave and a 100hz 1/2 wave- so lets see what happens
  12. I just heard the same thing. Our country has been allowing those stated above to go to school here at our Best up to date school, and they go back home to share the knowledge. Fuk that! You learn here you live here and should be a citizen of our country.
