Los Vega's HT

[vega2K]

Okay I took a plunge! I have purchased the pieces to build my own M&K push/pull Subwoofer!


- 1 x MPS-5320; B-Stock, black matte 2X12 push-pull sub-woofer cabinet (15.5" X 27" X 17.5") includes grill; made by Miller & Kreisel (M&K)

- 1 x Miller & Kreisel (M&K) VX-1250/MX-2500 250W Sub-Woofer Plate Amplifier

- 2 x M & K Sound 12 inch Woofers Model 17035, New, Unused, Bulk Packed Miller and Kreisel Super Fast Deep Bass

The end result should be something like this from ebay. Of course I will be paying about half of the asking price!
M&K Sound mk-2500 Miller & Kriesel mk2500 Subwoofer - eBay (item 200430258324 end time Jan-26-10 14:36:39 PST)

Wow! That's quite the project Vega, and even better at half the price! I wish I had the kind of talent you DIY'ers had, but this stuff is way beyond my comprehension.

Good luck and do post pics during the build!

Thanks Rhett! Once I get all the parts, believe it or not, I am expecting to finish in about 4 hours (knocks on wood). The hardest part will be cutting the amp openning to fit the amp (I may not even need to do that) and tapping screw holes. Then install the amp, install the drivers, wire it up, apply polyfill, and test. I 've read enough to know how I need to wire it up, so I think it is pretty straight forward.

4 hours?? Man... you're good!

It's just a very straight forward project. I replaced the driver in my sub and had to enlarge the opening and I had to tap holes and fill it with polyfill. It took me an hour. I figure the extra driver and amp would take an extra few hours. Remember, I am getting all the pieces I need, so I do not have to make the enclosure or paint it or anything like that. I just have to put it together. The beauty is in how much you save by doing it yourself.

These push-pull subwoofers work like dipole surround speakers that have their drivers connected out of phase.

As an alternative to push-pull subwoofer, you may want to consider building a subwoofer with one 12" driver and a 12" or larger passive radiator. Passive radiators are an alternative to bass ports and are cheaper than another subwoofer driver with excellent results. Almost all Definitive Technology subwoofers and Super Towers have subwoofer drivers and passive radiators.

I did not know that. Thanks Big Daddy. The drivers were not too expensive though at $89 a piece and when you consider a very similar M&K sub is going for $1400 at abt.com new, it's worth the cost!

Edit: Correction - the abt.com sub is actually going for $1800, check it out:
