Vertical stacking 2X210or2X212 system and head

1. With a $1000 budget what would you get? Why?
2. If you were building DIY cabs for above system, what would you choose for drivers?

Building a successful bass speaker cabinet is a combination of drivers and cabinet. Both have to work together well to get a good result.

If you check my avatar you'll see that for my purposes a vertical stack of a pair of 2x10s, Acme B2, does all I need. Of course your needs may well be the polar opposite.

That's determined by the speaker design. You choose the design based on your frequency response, dispersion, sensitivity, pack space and cost requirements, then use drivers recommended for use with it.

Whatever you do, you have to put them (the drivers in your DIY cab) on top of each other. How real cabs are built are incorrect. Cabinets know when drivers are side by side and introduce phrazings so you're not really hearing what you think you're hearing.

Love my vertical 212 stack. I use two EarCandy BassBombs. It is incredible. Only issue is making sure you have an amp that will fit on top! When I used this SVT I actually would place it on top of my guitarists cab and let him stick his Marshall on top of it. Now I have a light weight rack bag rig that sits nicely on top of these cabs.

I've been toying with the idea of adding another 112 Neox T to my 212 NeoxT, for a 312 stack. The 112 would be closer to my ears. and both of my current rigs can handle 2 .67 ohms. Two, 212's might be a bit much as far as the schlepp factor, and pack space for me, but a 312 stack is definitely in the ballpark. How much more spl is involved, 312 vs 412 ?

Just keep in mind that if you are running the 212 and 112 in parallel, the cabs will both get equal amounts of power, which means the 112's driver will get twice the amount each individual drive in the 212 gets.

Hopefully that made sense, here is the breakdown.

On a hypothetical 500 watt example rig, the 212 will get half, or 250 watts, which divides evenly among the two drivers, so each driver there gets 125 watts. The 112 cab gets 250 watts too, but it only has one driver so that driver gets all 250 watts.

Short summary: be careful to not blow out the 112!

+1 Although I have a few other options, this is my favorite.

Just an FYI - the NeoX212T is 4 ohms, and the NeoX112T is 8 ohms, so each individual speaker should get about the same power.

I use a power amp which gives me a few options, such as running two channels with different loads ( 4 in one, 8 in the other), or running just one side at 2.67 ,splitting the power equally to the 3 12's.. I believe that I can do the same with my Carvin BX1500.

The 312 will give you about 4dB more than the 212, but it will seem like more with the higher profile. The 412 will only give about 2dB more than the 312, so probably not worth it unless you find the 212 anemic.

In my opinion, no reason to use a dual 2x10. The sensitivity of 10" speakers is poor and the cost of the drivers at low budget or high budget would be the same as a 2x12. 2x12 will require less power and go slightly lower than a 2x10.

As far as a 1000 dollar budget with any current manufactures...None that i would recommend. The only 2x12 I would consider is a Genz Benz 2x12 which has a true vertical speaker placement and a decent slot port design. Using a cast frame Beyma Neo speaker it can handle decent power, but of course comes at a higher price. 2 cabinets would go above 1000$.

Other wise the only way to get what you want is to go custom build. For 10" speakers i would do a vertical 3x10 with 2 3"ports for each speaker. placed evenly and close to the driver.
For 2x12 i would do 4 evenly spaced ports for each speaker close to the drivers.

NO slot ports, NO off center speaker placement, NO odd/ uneven round ports. Equal spaced flared round ports.

Low budget Build, would assume that 4 or 6 speakers would be used to offset the low xmax and power handling. So a single cabinet would be out of the question, but 2 cabinets vertically stacked would offer excellent Sensitivity and decent power handling.

Low budget built/ must use 4 to 6 drivers for 250/300 watts

3x10 cabinet loaded with Eminence Delta 10A
2x12 cabinet loaded with Eminence Delta_12A

Med Budget Build/ can use 2 to 4 drivers for 250/300 watts
or use 4 to 6 drivers for 400/500 watts

3x10 loaded with Eminence S2010
2x12 loaded with Eminence Basslite_S2012

again NO slot ports, No off centered drivers,

Evenly placed round ports mounted close to the driver.
tune 5to 7hz above FS and keep volume close to the recommended volume supplied by the manufacture.
