Ricci,
WOW that SUX, makes my stomach turn just looking at it.

thanks for the kind words about the box, it is interesting. Every time I fiddle with it something changes, I took out the fifth pillow and re-arranged them, now the tuning is so low it seem ridiculous(9.2716Hz). It ended up measuring best on it's side so now I'm considering a 24"x24"x36" version with a larger port to raise the tuning back up & pick up some more efficiency.

When I received my EP2500 it felt like something big was a little loose or moving around a tiny bit. As the powersupply is secured into the frame with a large screw I figured the screw was a little loose. I haven't done anything with mine. It appears to work just fine.

I actually thought this was the norm?

I just ordered a Maelstrom-X myself. I've got an EP2500 to power it. Will this box be able to handle it? Will it be the "ultimate" box, without the port restricting the maelstrom+ep2500 in any way?

My setup is dual Maelstrom-X's on EP2500's, they handle it just fine. A subsonic filter is mandatory to protect the driver below box tuning.

A bigger box with a larger port would give you more,I am considering a 24" X 24" X 36" version.

The response of this box is very similar to a sealed box of the same size(6'³), it's just 2.5-4.5dB more efficient.

A bigger port in the same size box will give you higher tuning, higher vent velocity's, and less bandwidth.

With a box tuned this low I would say that the restrictive nature is much lower in frequency than that of %99 of ported boxes. In listening there are no port noises. Even at levels that will make the drywall rattle.

hey dan, how would this box be with a mach5 IXL 18.4? I'm looking to build but haven't quite settled on a box yet and this one looks like a very good option. Or is there a better ported box option for those drivers?
I will be building 2 and with the port the way it is, would you be able to stack them top to bottom?
I'll be using a ep2500 for da power.
I also have the ear's plans for dual sealed versions, I just haven't decided which way to go.

BTW, did you figure out a 10Hz subsonic filter for the EP2500 yet?

Like so?


The IXL response is similar to the Maelstrom-X in this box, but did you see my IXL 18.4 box design?

The EP2500 appears to have EQ's instead of filters, I don't think there gonna work for subsonic filter duty

Doesn't the EP2500 have a filter somewhere below 10hz? I would bet that everyone has significant rolloff below 10hz in their electronics chain. I know I do. If this cab is tuned to 9 or 10hz do you really need a HPF?

ahh holy crap how did i miss that pic? LOL Well The answer would be yes then.

Well I don't know how to design one myself so I figured I'd just use one I found on here. Your easy button one has the look and size I want, though the tuning might be a bit low but I'm new to the DIY stuff, so in reality I don't know lol but I'm learning.

Your other design looks great but I would need the driver and port on the front, driver on the side will not work in my situation. I like the look of the first one but If the mach5 driver will not work so great, I can find another box that will work better.

plus all the numbers are there so I'd know all the cuts and stuff I'd need, so it would be "easy" to build lol
thx

Ricci,
the stock Bridged EP2500 peaks at +6db @ 3Hz

N8DOGG,
What tuning were you interested in?

As for the EB IXL18 box, you could always put a long curve elbow on the 6" port to get it on the front with the driver.

Now that I re read the posts the tune is 13.5? if thats the case as long as the mach5 will work, I'll be golden.
I though it was 9hz something but it looks like you stuck a bunch of pillows in there to get it that.

I like the look of that box the best of any I've seen so far.

edit. sorry by front, I meant the driver on the same place as the port with the port either above or below it. but If the other one will work well, I'd prefer to use it cause its purdy lol

It does!? I did not know that. Is there a response graph I could look at somewhere? That would need a HPF then. Crown uses an 18db octave filter at 8hz on most of it's stuff.

I just sold one of my servo 15's so it's time to start building!! wooo hooo!!
I'm gonna use this box as my build, thanks for the design dan!

Those mach 5's will be rearranging my organs in no time!!!!

N8,
If your going to go Mach5, and one EP2500 I'd recommend 4-MJ18M over 2-IXL18.4, that's a better impedance and power match for the EP2500, very similar cost wise. Build some big boxes and you will have way more bass than you'd need.

I'll just buy another ep2500 then. that was going to be my plan anyways so I'll just get 2 because I already ordered the drivers.

I'm also looking at building this box, and using an eD LT-1300 for power. (already bought). Only thing left to decide is the driver. the Mach5 IXL18 would be the easiest, as I'm in Canada. Also contenders are the (of course) maelstrom X18 and possibly the eD 19oV.2.

Opinions - would the Maelstrom X be enough of a performance improvement from the IXL18 to warrant the extra cost of driver and shipping / duties / taxes etc?

How well will the IXL18 perform in this enclosure? anything I could do to tweek the size / parameters of this box for the IXL? larger size is no problem and if i need to use 3 sheets of MDF then so be it!

I do love the look of this box and its slot port(s)!!

From a fellow canadian... if you are contemplating ordering from eD, be forewarned that they only ship UPS, and to the billing address. It cost me about $ 64 or so in brokerage and other BS Ups fees... also my wire crossed the border back and forth 4 times before they released it, and I got it about 4 weeks after ordering.

I've already got an EP2500 pushing an IXL18.4 in your Easy Button box for the IXL. Plan on building another... for, uhhhh, symmetry, yeah, that's what I'll tell my wife! Anyway, how would you recommend wiring that setup? Stereo? Series? Parallel? Keep in mind I really can't remeber which each of those means...

You can always buy more (and more expensive) subs and more (and again more expensive) amps, but on a "bang for the buck" scale, the Easy Button combo kicks some serious ass. The telltale sign is the grin and sideways glance from friends and family when I demo my HT and the couch is vibrating. I'm not really technical about this stuff, but I know what I likes... and I likes dis!

Just to clarify things a bit, Devon built the bigger IXL design. It is a great way to go unless you just don't have the space. It is easier to build.

thanks for the kind words Devon

****
soundemon,
LT-1300 should be a decent match with an IXL18.4

****
Everybody,
Bigger Is Better(for the most part), if you can go BIG DO IT IF YOU CAN
The EB/IXL18.4 design is a real easy build that performs very well for everyone that's given feedback after building one so far.

Hey everyone! First time posting. I really like this design, but my cheapness wants to know how well the dayton 18" will do in this design? I can't justify buying something like one of the SVS Ultras, but I can't seem to justify ~$500 to build this. I can afford it, just want to know if it can be done for less? One other question is who else makes 18" drivers? Is there a list of manufacturers somewhere?

You'd be better off putting a Shiva-X in this box if you wanted to save $ Run it off a PE BASH 500.

The Shiva-X should get down all the way to 10Hz in room, fairly easily

The Tempest-X really needs a larger box

But for this you could use 2 handi panels instead of the 4th sheet, to save some money. I just noticed Friday when I bought MDF the pricing for 4 handi panels is almost exactly the same as a regular 49" x 97" sheet.


Dan,

Any chance you have the cut sheet handy for that smaller 15" slot load?
