  1. THE FOLLOWING ARE THE FINALIZED PARAMETERS FOR THE 12 INCH AND 15 INCH DSS ETHOS TRANSDUCERS (NOTE: physical dimension will be added soon) 12 INCH DSS ETHOS re 3 ohms Le 2.94 mH Qms 5.91 Qes .54 Qts .49 Fs 28.24 hz Mms 326.15 grams Cms .1 mm/N BL 21.43 T/M Vas 33.1 liters spl 84.99 1w/1m sd 490.87 cm^2 xmax 32.5mm per 70% Bl rating recommended power 1,800 watts 15 INCH DSS ETHOS re 3 ohms Le 2.94 mH Qms 10.6 Qes .69 Qts .64 Fs 25.78 hz Mms 362.9 grams Cms .1 mm/N BL 21.43 T/M Vas 95.93 liters spl 88.22 1w/1m sd 804.25 cm^2 xmax 32.5mm per 70% Bl rating recommended power 1,800 watts The design goals of these drivers were to create around 3 db of ripple and a f3 of 28 hertz in a recommended ported enclosure of 3 cubic feet for the 15 and 1.5 cubic feet for the 12 tuned to 32 hertz. Below is a screen print of the 12 and 15 in their respective enclosures.

  3. Would there be any interest for a 30 pound Ethos that was around $450 as an option in addition to the regular 65 pound Ethos?

    Ethos and Trident preorder

    In the next few days I will open preorders for the Ethos. Pricing will be as followed. Pricing does NOT include shipping. ETHOS 10" retail $322.95 preorder $273.95 12" retail $329.95 preorder $279.95 15" retail $339.95 preorder $288.95 18" retail $359.95 preorder $305.95 TRIDENT preorder won't open for about 6 weeks but preliminary pricing looks like this. for those not in the know, the Trident is the first and only transducer ever developed with three air gaps. It uses a large 11" OD triple gap MMAG motor with 3 inch 8 layer coil. Box specs will look similar to the Ethos. Power recommendation will be around 2,750 watts rms. Xmax will be limited to the the driver's suspension which is about 45mm one way. rearward xmech is 50mm. The triple gap is used to increase sensitivity, maintain BL, and reduce power compression. The BL curve will look a bit odd and numbers look like the following. It will retain 100 percent BL all the way to 20mm one way. From 20mm to 30mm one way BL evenly drops to 70 percent. From 30mm it retains 70 percent bL all the way to 40mm one way. And it achieves this with a moving mass upwards of 40 percent less than a conventional overhung driver. 12" retail $590.95 preorder $502.95 15" retail $601.95 preorder $511.95 18" retail $626.95 preorder $532.95 And as always I will offer Lay A Way
  5. Below is LPM or your typical small signal T/S parameters which I DO NOT use. (I'll get to that in a minute) ^ AS YOU CAN SEE THE CONE ONLY MOVED ABOUT .1MM THAT'S ONE TENTH OF A MILLIMETER! Large signal being uploaded now.

    Welcome to the IHoP v.2

    I sure did and like I said if you have a problem with it go whine to Mark and Aaron. If they want to deal with your nonsense over my money tell them I'll be happy to take it else where.
  7. The DSS section is a paid forum section dedicated to the advertisement of the Direct Sound Solutions brand and it's customers. Endless bantering will not be tolerated. If member or especially a moderator does not agree with the specifics of someone else's post, notate your point and move on. If need be the issue can be brought to an open forum section, the technical section for examples. The same goes for OP's do NOT stir the pot. If you do not agree with a remark, notate that you have heard their point of view and that WILL be the end of it. In here I am GOD and I will not allow activity that shames the DSS and SSA brands. If anyone has issues with this take it up with Aaron or Mark.

    I can refund your payment if you like.

    Perhaps an explanation? Very different results when tested...

    First off the dats is a hunk of junk. The specs it's showing is proof of that. Assuming you used the added mass method it's calculating a mms of ~10 percent more with a Cms that's nearly identical and a motor force factor that's enormously different. It not physically possible.
  10. Quentin Jarrell


    If you look at the "distortion analysis" graph you will see that the suspension and inductance is inducing 30-40 percent distortion (in other words playing 40 percent more signal than the pink noise being played). This is why you have to look at specs that deal with linearality and distortion in context.
  11. Quentin Jarrell


    Distortion caused by the suspension in the sub realm is inaudible. But this is a common occursnce in most every suspension. You'll see some transducers with spaced spiders and the bottom set will be inverted to help offset the nonlinear action of the suspension. But the edge (surround) plays a huge roll also.

    LOOK AT THE HUGE DIFFERENCE IN PARAMETERS. The LSI shown is a bit different than the ones I publish because this is an instant snapshot at zero xmax during testing. I take 10 points throughout the testing and average them to get average LSI parameters. Below is the set up for the klippel. Basically telling it how much power to give it and how to limit excursion based on percentage parts limits (limits used when distortion can become audible). Below is how far the cone moved during large signal identification.

    Just another newbi ?

    Email was replied to at 1402 central time. Don't let anyone fool with it and risk losing your warranty.

    Thinking of switching sub setup..

    going for spl..yea maybe 3.5 that is just me though..Uh no, I'd stick with the manufacturers recommendation. A box that large tuned that high WILL sound horrible.

    Welcome to the IHoP v.2

    etiher your not following the 10 percent rule or its and ID ten T error.

    External PA Speaker?

    here we go

    External PA Speaker?

    this thing had 8 pair also I beleive.

    ^ that is a pic under the driver side of my Tacoma. The boxes on the tail gate was the vacuum formed enclosures.

    External PA Speaker?

    That truck has had the same speakers in it since 2006. He pressure washes them weekly. The MDF boxes had to be replace with birch about two years ago but the speakers are in perfect condition.

    External PA Speaker?

    I made this popular. In the late 90's mobile one autosound built an impala for master p full of Bazooka equipment. One of the things installed was a couple pair of 6x9 marines Somewhere around 2003 I installed 8 pair of 6x9's under a 69 caprice droptop for New Orleans Saints tightend Boo Williams. Soon after I was installing on average 100 pair a week. The people who couldn't afford my work went to radio shack and bought PA speakers. I had a 2005 Tacoma with 48 pair of 6 1/2 marines in vacuum formed abs enclosures under it.
