I am going to a VMPS Larger Copy with the TC Sounds 12" and 15" with an 18" PR...

http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=293-658&scqty=1

http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=293-662&scqty=1

http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=293-684&scqty=1

The box will be 2.25" thick walls - HEAVILY braced with magnet supports on the inside of the cabinet...

Unlike Brian's original design I am going to build it with a BASE to the subwoofer to fire into so the slot port will be perfectly implemented and not dependent on the floor - air tight if you will...

The base will be 1.5-2.25" thick and will have Castors mounted to it

I project the sub will weigh 300-350 pounds of awesome.

I will have two sets of speaker terminals to power each coil set -- basically will need two 1,000 watt amps to properly power it..

Should have usable output down to 11hz....

Brian Cheney is doing this modification already except mine will have a Larger PR capable of handling all the excursions of the active woofers (3.5" per speaker)

It should be intense...

    I may go out and buy the MDF tomorrow and get started.

    It is happening - plain and simple. This will be born...

    Going to do 1.5" thick MDF panels with 3/4" Cedar or Oak overlay for the finish --- just do a nice Satin finish....

    All corners roundovered 3/4 ---

    Base will be 2.25" MDF -- with the edges being cedar or oak -- and the MDF painted black...

    The part that form the base will be extremely heavy duty...

    This is going to be AWESOME

    The Enclosure should be around 200 bucks....

    The woofs are 770

    Amps will be around 400

    1370 for AWESOME

    LOL - I am definitely freaking insane...

    But what is even more insane is if you think about it - this is not a lot of money. Infact it is far less money than the Ultra...

    I am so pumped on this...

    I already have a buyer lined up for my modded VMPS and as soon as it is paid for I can jump on this... I already have a Crown Amp - just have to add one more and build the enclosure and I will be set!

    Yep - Since there is virtually no bracing in the VMPS getting measurements for internal volume is a piece of cake -- just exterior dimensions - 2" per side (1" thick walls)

    What an easy enclosure to build ahhahhaahha

    This is going to be awesome

    I think, but I could be wrong, that it is 1 pound per 1 cubic foot of volume. This should be an awesome build, can't wait to see the final product. :biggrin:

    I am projecting 10 - I am going to see if someone on VMPS's forum will tell me - otherwise I may put it in a plastic bag and weigh it at work...

    Thanks for the encouragement...

    I think I am going to install rods on the back of the sub where I can insert weights

    350# without weights....

    The sub will still move - so If I can insert maybe 2 - 50# weights on the back to balance it out between the drivers it shouldnt move to bad

    I thought of this after we talked Trey.....what about steel plates, maybe 2 or 3 of them enclosed in the base? Or would this be bad for resonance?

    My bracing concept is very simple - because if I were to do the modern bracing after accommodating all the drivers within the enclosure - the bracing would be non existent after allowing adequate air flow and so forth....

    So with the thickness of the enclosure and so forth this should be adequate...

    I enlarged the box to compensate for the bracing as well...

    Here are the current dimensions of the box -


    Larger Rebuild Exterior Interior
    Width 29.5 27.5
    Height 21 19
    Depth 20 18

    First Box Shell Dimensions
    Width Height
    Left Side 19.5 19
    Right Side 19.5 19
    Front 27.5 19
    Back 27.5 19
    Top 29 19.5
    Bottom 29 19.5

    Second Layer Box
    Width Height
    Left Side 19.5 20.5
    Right Side 19.5 20.5
    Front 30.5 20.5
    Back 30.5 20.5
    Top 30.5 21
    Bottom 30.5 21

    Third Layer Box
    Width Height
    Left Side 22.5 23.5
    Right Side 22.5 23.5
    Front 30.5 22
    Back 30.5 22
    Top 30.5 22.5
    Bottom 30.5 22.5

    So the sub with no platform will be --

    22.5 D x 23.5 H x 32 W

    I would guess at that point roughly 250 pounds w/ drivers.

    I have not measured out the base/port or the platform yet...

    Are you sure that the PR and the 15 active will fit? Specifically around the magnet?

    Yes

    The PR is only 8" deep, with the 2.25" thick wall - that leaves about 5.75" in the box (the box is 19" high (interior) -- so that puts the center of the box at 9.5"

    So if I mount the 15" on center and the magnet is 7.75" wide -- that puts me at roughly
    7.87" of clearance when you combine the interior dimensions with the panel thickness...

    So the PR should have 2.5" of clearance under the 15" active

    The 15" Active is only 7.8" deep -- and with the 2.25" thick wall that would make it only go in the enclosure approx 5.6 inches

    I am trying to figure out how I am going to build it - I think the best way would honestly be to build it without a top or back at first so I can cut the driver holes and line up the bracing accordingly.... Would make for a cool picture

    (Just the initial box of course)

    Whatever you guys come up with and I like I will get a plate like this made for the front of the base of the sub...

    have you "designed" this thing in any way? taking interior volume measurements from a sub that uses a 12" and 15" driver with a 15" PR, then using completely different drivers and an 18" PR..... and just hoping it will make 11hz?

    seems rather optomistic that it will do what you are wanting it to do, sure it will go boom boom, but without some proper design behind the enclosure, driver and PR, your just guessing your 1400 bucks will give you great bass

    call the thing - Supposition

    Good luck, I am only asking because I would hate to see you waste the time and money.

    Why not ask TS Sounds for a box design using the drivers and PR you have picked out?

    Dodd - Battery Preamp
    Monarchy Audio SE100 Delux - mono power amps
    Sony DVP-NS999ES - SACD player
    ADS 1230 - Polk SDA 2B
    DIY Stereo Subwoofer towers w/(4) 12 drivers each
    Crown K1 - Subwoofer amp
    Outlaw ICBM - crossover
    Beringher BFD - sub eq

    Where is the remote? Where is the $%#$% remote!

    Only reason I am doing this is because Brian Cheney at VMPS is doing it with the same size enclosure and a lesser PR...

    He is calling it the OMG series (which is silly)

    index.php?action=gallery;sa=view;id=43715

    Yep Brian is taking the same sub enclosure with a PR tuned to 11hz with a "high throw"

    So I am going to take a 18" PR with adequate throw to match the actives tuned to 11hz in a box made to withstand such woofers.

    Brian Cheney is charging 1499.99 for the Larger with both TC Sound woofers and an inadequate PR --

    I can for 1350 build a far superior box, with a far superior PR capable of hanging with the active 15" and 12" and have two 1,000 watt power amps driving it for 150 dollars less.

    No brainer...

    Brad (Early B) has already upgraded his VMPS 215 with the new TC Sounds woofer and Brian's "BIG BUMP" PR -- he loves it, however he has already blew the surround off the PR...

    He is ordering the TC Sounds PR to match his sub, the 15"

    So the enclosures will work -- Brian is just skipping alot of corners...

    If anything I may keep the 15" PR in the mix instead of the 18"
