If you thought that the 8"s were a good deal

Amazing
I want 8 of them

i am new to the diy speaker world, i have started to do my homework but haven't yet entered the realm on subs, as i do plan of building a budget sub in the future is this something i should jump on now?

If it is budget you're after, yes, jump on it before they are all gone.

what Voice Coil option do you think?

thanks for the heads up.. i ordered 10 of the 8's when they were mentioned and i just ordered 3 of these 12's to go along with it.. thanks again

Shipping is almost as much as the drivers. Didn't stop me from ordering (4) 4 ohm ones.

Spezzy, seems you want 8 of eveything that comes up for a decent deal.!


I can only speculate, but the 8 and 12"-EHQS drivers are not being bought/sold to their vendors anmore. At least these versions. So it might lead one to belive eD is cleaning shelf space & building out the drivers and selling them out.

I suspect the 12's will run dry as the 8's did in a few days.

I suspect this is whats happening as it has been done before with other eD drivers, tho those woofers were from eD's own subwoofer lines. I most certainly could be wrong, but if you want one or mre, I'd not dilly dally to long.

Just a possible heads up guys.

If you can handle a decent sized vented encloser, than this is a great woofer deal to get started with a DIY subwoofer project. Also, very little power is needed with when used in a vented alignment to drive it.
Ben, eD's owner, has a thread somewhere on icix's forum for a quick simple 12"EHQS sub build. Maybe I or someone else can find it, he did post it quite awhile back tho. You can always design your own but I think he hit it pretty good for the mix of spl and extension for it.

As far as what VC that depends on how many you want to drive and with what... If it's just one sub, the 4-ohm likely is the your best bet as it's easiest to drive with most any amp, plate amp or other.

Ordering only 4 for my friend tomorrow hopefully. He needs a sub lol.

I got eight 8" subs (four for me and four for a friend). Now this comes along and here I go again. Well I just bought four 12". I'll wait till they come in and I'll have a little tea party amongst my twelve subwoofers.

I'm assuming you're talking about this one

I just picked up a few more of the 12's .. gonna build a couple for xmas gifts for my brothers.. nothing says christmas like BOOM

Each one moves roughly 1liter of air at 13.50! That's cheap...

For IB, two array's of 12 would displace around 24L of air and cost maybe 400.00 after shipping. Each array could be wired up into a 3ohm load, which would be perfect for one channel of the EB2500. 720w/12=60w per sub. That might even be a bit much for them.


Ok nevermind. Maybe factor 500-600 for 24 of them then. I figured if you bought a lot, they'd be able to palletize them or something to help save on shipping costs. They are located in Iowa, one could always drive there and pick some up I guess.

Tempting to buy for some sealed boxes.

Looney, drop that to 16 drivers and you can get a 4ohm setup. You lose only 3dB of possible potential, and it comes in under $500 delivered.

Using the same EP2500 amp you might even make more clean SPL due to the better power distribution.

16 liters of displacement is nothing to laugh at.

Just thinking aloud... for us cheapskates. You know who you are.

EDIT: Make that less than $350 for 16, under $500 for 24 to N FL. Must resist urge...

HAHAH...if someone really wanted a pallet, we could do it

Reminds of of ancient school car audio, where there was no
great subwoofers and people had to cram a ton of common
woofers in the car to get bass SPL up there. /hehe/ ... The same
idea applies to home audio, an array is nice and you have more
room for the installation than the car.

Geoff,

You're close.

The EHQS lines are OEM over runs. Basically the extras from a massive production run for an OEM customer. They didn't want to purchase them and they allowed us to sell them.

Now it's just coming to the time where we can't really afford to keep so much warehouse space given to pallet upon pallet of these things and we've got to clear them out.

You are right though in the fact that we will likely not be offering these again. At least not until more are needed by the OEM customer and we have overstock again.

And yeah, the 8's lasted for about 9 hours after the newsletter went out. I suspect the 12's will stick around a bit longer than that due to the extra cost but I can't say for sure.

I just order 4 of them. 3 for a friend of mine and another to go with my other 12" i had already ordered

Can someone design a ported box for 2 of these? A slot port would be great. I am planning on building one of these for a friend and just bought 2 of the 4ohm versions. I will be using either a 270 or 300 watt plate amp to power them. Thanks!

Except those cars couldn't do numbers that cars with one or two subs can do today.

I got 4 last year when the line was introduced, and built these two towers (these pics were taken before the laminate was put on)






For $13.50 I picked up 8 more. I'll figure out something to do with them!

ashardin - those towers kick arse. Any pics with the laminate?

Woot just got me one and the 4in AeroPort will pick up a little 100watt amp and build the box in the link

and pair this up with my H-100

Ordered 4 for my friend. Tempted to order 4 for myself..

If you ~{plan to use 2 drivers in one cabinet and power it with a single plate amp}~, you might consider calling back and getting the 2-ohm version. Then you can wire the two 2-ohm drivers in series for a 4-ohm load to your plate amp.
Other wise, using two 4-ohm drivers in one cabinet your stuck with either a 2-ohm load or 8-ohm load to the plate amp. 2-ohms not plate amp friendly and 8-ohm dropping your plate amps power output.

As far as a ported design for 2 drivers, just double up the cabinet volume of eD's design for one driver and use the same tuning, 20Hz..

Being that the EHQS 12" driver needs a somewhat large ported encloser ~{for just one driver}~, using a slot port is just going to make the encloser even bigger. Might be a better choice to go with a pair of 3 or 4" Precision ports or even flared PVC pipe, unless you don't mind the added encloser size when using a slot port to save a few dollars.

Being that ashardin has already built a pair of dual EHQS 12" driver enclosers you might ask what he went with for his encloser ft^³ size and also the tuning frequency he used.

If your going to purchase a plate amp for your dual driver EHQS DIY sub, you might consider the PE-240. It's rum filter is a very nice fit if you choose to go with ~{eD's internal volume x two and it's 20Hz tune}~. 120-watts per driver is about perfect for this with the rum filter helping out to protect the drivers below tuning..

The link to eD's 12" EHQS sub build with all it's necessary information is below. Just me, but I'd add at least one brace inside.

Thank CarlsonCustoms for digging that thread build up..

I wonder if I could power one of these with the receiver I have which is rated for four ohms with 100w rms...since the budget is so tight right now.

Ordered another one for my other friend lol.

I can not find them on the web site?
I see the (no longer available 8").

eh, nevermind..
