  1. Did Quentin really just make a post in "his" forum calling out "especially moderators"

    I don't give a fuck who posts what and where, if the information is bogus it will get called out. This exists whether I am a mod or a member. I won't be a part of a nonsensical board.

    *amusingly the topic that I am pretty sure caused this was sent to me in a PM asking me to respond because of the nonsense.

    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.


  2. 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.


  3. Is the suspension stiffer on the rearward stroke? Probably not a big deal for a subwoofer though.

    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.

  5. 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.
