    hehe - pretty much decided when I buy the plywood I am also going to invest in a little set of hand trucks -- as the weight of this thing ALREADY is insane

    Very impressive! I cant wait to hear the results.

    thanks!

    Honestly I do not know - pretty much at this point I am letting the weather decide, cold and wet = working on the house, warmer and dry = working on sub...

    At this rate, armed with my router --- I would guess I can be done in 2 months

    2 months - thats like another season!!! :biggrin: Can we wait that long to hear the results?

    For those that are interested in taking on this project, it would be cool if you could put together a parts list needed. Just a suggestion though.

    Have you thought of the finish you plan to put on this sub?

    I am thinking of finishing it with just a satin pine (light finish) with dark wood (wenge) side panels...

    And misc areas like on the bottom and such will be painted black... but that is still racking around inside my brain

    Parts like is pretty simple...

    12" TC woofer, 15" tc woofer, 18" tc pr - terminal cup (two sets needed)

    Two 1,000-1,500 watt amplifier (one for each woofer)

    A **** ton of wood and patience

    Give it a 70s throwback look - two tone color!!! Remember those cars having a two toner on them?

    hehe - I was trying to think of a way to make it not look like a big **** box...

    I was thinking of making it a vertical design like the tall boy with a side firing PR that fires into a slot port - should work the same... decisions decisions

    Thats pretty hard to do when your sub is on steriods. :biggrin:

    lol -- yeah the more I think about it I think making it vertical with a side firing PR would be down right beastly --- and much easier to build...

    I say that anyone interested in this post should invite themselves to VR3s house for a listen upon completion of the project. Is there an "ooh and ahh" factor in the specification sheet?

    It should be -6db 20 hz, -10db to 16hz --- without room gain or the slot port.

    With the slot port reinforcing the PR it should be -3db 20hz, -7db 16hz -- and Room gain should make it roughly flat at 20, -3/4db at 16hz and capable of usable 10hz...

    But with 2,000 continuous watts it should be able to crank out 120-130db at 50hz ;)

    How is that compared to the setup you had running with the VMPS?

    The VMPS only handles 750 watts... so not sure as far as numbers

    This sub will have a power handling of 2,000 continuous and 8,000 peak...

    So from a power standpoint alone it should be huge.

    Not to mention a xmax of 3.5" vs. 1-1.5" --

    Power and throw is way larger. I could essentially EQ this subwoofer anyway I want and throw as much power as I want to it without consequence...

    It should be able to fill up a large room, small room, medium room - whatever really

    Here is my current thought process...

    Obviously this is not proportioned correctly ;)

    Why does it look slot loaded?

    Because it is ---

    VMPS slot loads their PR, but they use the floor as the base

    FYI, that's going to affect your tuning.

    I know - this is pretty much an exact rebuild Mike...

    Brian uses these two drivers in the same box, with that slot port with a PR tuned to 11hz

    These results are excellent...

    Gents we just fired this up in its rough MDF form - no slot port on the PR...

    ran some quick sweeps - EASY below 15hz extension and just wow - we are only running 800 per speaker (only a 1/4 of the power needed) and the amp was peaking at points and the sub was hardly working...

    The sub is a success and now I am pumped back up to build it - I was worried it was going to flop but jesus h christ. Intense is an understatement

    I have experienced a PC Ultra from SVS (The older one) and it has nothing on this. WOW

    You need to compare it to the PC Ultra/2 from SVS and let us know your results!!!

    I cant wait to hear what your final results are!!!

    Those pics are impressive!!! Will the sub be able to power up from a single power outlet, or is it one of those beasts that need two seperate outlets on different electrical circuits?

    What binding posts did you use?

    This was just a mock up - we used the post from the Taylo Reference II

    and the final product will use two 1500 watt amps on a dedicated 20 amp circuit

    I would use a recessed speakon jack.

    I just noticed your place is already recessed, so it's a little late.

    I'm starting to like Speakon plugs for their convenience. No chance of reversed polarity, sturdiness, only a small amount of mass added to the signal chain, etc...

    Regardless, very cool build!
