    Last Tuesday, I called Ampman Audio (the authorized dealer I ordered my Tumult from). They returned my call and stated that Tumults were shipping last week. Anybody get their Tumult yet?

    Yeah... yeah... yeah...

    I know you already had yours. I was asking all of the people who hadn't already gloated about getting one if they had received theirs yet. [​IMG]

    No, I haven't received mine yet. [​IMG]

    But, my enclosure is completely finished and ready to go.

    sorry, don't mean to go off topic here but....
    What type of enclosure did you make for it Dean?
    Dimensions, sealed, PR's or ported?

    I was just teasing myself. Please don't take my comment seriously. Hope you get the enclosure buttoned up soon so you can give us your impressions.

    After consulting with Kyle numerous times, I decided to go with a sealed, 74 Liter, 19 1/2 " cube powered with the HS500 amp.

    I laminated it with flat black Formica and had Kyle supply me with a grill.

    I use my system about 75% for music. Hoping this will give me a sub with excellent sound quality along with some punch for HT. [​IMG] And since this is my first sub, I am really anxious to get the driver.
     
  9. Dean, for music, that alignment should work out nicely. You can then Enable the parametric EQ on the HS500 for some extended lows for HT duty [​IMG]

    ..and if you do not like it, I will be happy to take the system off of your hand. I will even offer you top dollar! (..that is my pennies on your dollar [​IMG])

    here is a quick pic of my Tumult and the dual spider 2500d Stryke PR's.. The PR's have a big spoked basket like the tumult, too cool.

    Hey Craig,

    Nice!

    What's the finish? I love textured bulletproof bedliner-esque finishes. I've been experimenting with automotive rocker-guard/undercoating.

    They are to pretty to hide. He could use an acrylic panel in the enclosure and pick up an additional 6db to boot.[​IMG]

    Newbie alert!

    Craig,

    Does your enclosure have any internal bracing? I don't see any. I'm surprised for such a monster sub.

    Curious, what is the advantage of 2 PRs over just 1? Looking forward to your review.

    thanks,

    Al

    Al,

    When using PR's you want them to have a minimum of 2x the displacement of the driver (4x is better). In this case, the Tumult has 5.1L of displacement and each 18" PR has 6L of displacement. So using 2 of the 18" PR's gives you 12L, which is a little over double that of the Tumult.

    Al, in addition to Brian's point about the required displacement (btw, according to John, the 18" models displace ~9L) it's important to use such monster PR's in pairs so that they can be mounted in such a way that their motions are opposite and cancel each others effects on the cabinet. If not, the shaking can be considerable. You can see the two larger holes in Craig's box are for this purpose.
    As far as bracing, these big PR jobs rarely have much surface left to resonate after all the cutouts, so required bracing is minimal. Looks like doubled 3/4" MDF all around, so bracing might be superfluous.
