craig, are you going to get an epik and battle it out between that and the a7-900. Also, is that sub you have an a7-900 or is it just the box and you are going to put some other drivers in it?

I have a call into Chad about getting a unit for testing. Now how to get another monster sub past my poor wife ...

Chad ... If you are reading this ... I will BUY the sub ...

mwolfe ... I have an A7-900 ... and this comparo along with the Def Tech Trinity and the new Ultra are TOO good to miss.

I've moved a discussion that started here to this thread, where it is more appropriate.

Tom Nousaine has tested the DD1812 to produce 104 dB at two meters (our listening position) at 20hz. So we're off by about 16 dB. Room gain in a typical listening environment is about 6 dB at 20hz. So now we need 10 dB. Each time we double the number of subwoofers, output increases by 6 dB. Since decibels are logorithmic in scale, tripling the amount of subwoofers will increase output by ~10 dB. This is why you need about 3 DD1812s to match the output capability of the T8s and S8s.

Actually, if you bothered to read it, the information was merely posted by the manufacturer. The measurements on Epik's website are the result of Tom Nousaine of Sound and Vision magazine who's spent a good deal of his career providing measurements of various subwoofers (different from reviewing). Do a web search, you might learn something.

Hmm for how "good" that epik subwoofer is you would think it would have made a list or any list.

It isn't on the list because it isn't for sale yet. I would be surprised if Craig doesn't test it when it becomes available.

Quote:


Plug away buddy plug away, I don't see any of those "epik" subwoofers making the list anytime soon.

For your information, I have no affiliation or interest in Epik subwoofers. The only reason they were brought into the argument was because they provide a single link to Tom's measurements. I haven't bought anything BM or ID in a long time and have turned to DIY, in order to provide the performance I want, in my price range. For those interested in Epik products, I'd direct you to this thread. If you want to challenge their performance, Blueray, post there, please. I won't respond to any more of your posts in this thread (as you can see, Craig clearly intends on purchasing one to add to his list). For anyone familiar with the DIY world, the name Chad Kuypers says it all.

Quote:


Look like a lot of people do not trust the tests that Tom Nousaine did.

Mind providing a link? I think what you are referring to was someone comparing the results of an Ilkka test to a Tom test. Comparing results from two different people in two different places is never a good idea - it was this idea that was challenged, not Tom's tests. No one in that thread challenged the results of Tom's tests.

Quote:


Right in the epik subwoofer thread, since tom did not mention how he tested the subs.

Are you blind?

He wasn't plugging any sub.

Tom Nousaine measures subs, doesn't review them.

There are plenty of good subs that are not on the famed list (yet). Epik subs in particular.

DD1812 is terribly overpriced for it's performance But hey, at least it looks extremely nice.

Hey craigsub. So when is this "shootout" going to occur? Maybe I should fire up the truck and head on out to PA? (I love road trips... ) Even so, I already kind of know how this test is going to turn out. Plus we will post 2M GP results of the Conquest for people to see on the website shortly. If you think people got fired up at the Nousaine results, wait until they see these...

Shipping was changed today and is lower. We just put up the subwoofers for sale and offset the cost for those that ordered until we fixed the price difference. We are Located north of Chicago by the way.

I pushed the release of the veneered subwoofers back because I found a better finish for the veneer. We are now using a magnificent (expensive) catalyzed laquer for the Rosenut cabinets. It comes in gigantic containers so we have to wait for it to be mixed and sent. Once it comes in we will start spraying the cabinets and start shipping those out too.

Chad, while this thread has your attention, are you planning on releasing sealed subwoofers as well? I noticed that you made the "ported" distinction on your store webpage.

Yes. Absolutely. We have sealed versions of all of the Epik drivers designed already. The drivers feature suspension modifications that result in more output in a sealed setup versus ported.

We were originally going to wait a little bit to release these, but the interest has been growing quite a bit. With absolutely no sealed 15" subwoofers in the direct online market to offer something cheaper than the popular (yet expensive...) JL and Velodyne products, I feel that this would be a great thing to just get out there ASAP. We have designs for single 15" sealed, dual 15" sealed and even 18" sealed designs waiting in the wings.

If the interest is there, we could honestly start selling 1000 watt dual 15" sealed subwoofers next week. The cabinets are all designed and ready to go. All I have to do is hit "start" on the "Epik dual reference sealed enclosure" program on our CNC router and cabinet parts will start appearing before our eyes...

Hmmm...

Hold the phone!

Does this mean that you can make a sealed sub that is at least as good as a JL F113 for less money? If so, what size would it be? Many of us (like me) are looking for something small -- like the F113.

How much for dual 15"? Any specs?

Just curious, is it a problem with the amp regarding the distortion at 16hz as well as the protection device coming on? ( re Tom Nousaine's test)

My point is simply that there is an enormous absence of larger single driver sealed subwoofer designs in the direct online subwoofer market. Also, almost all commercial sealed subwoofers (even the Fathom) all distort heavily below 30-40 Hz. And when I say "heavily", I am simply stating that to reach maximum output they will go well above 10 percent distortion limits. Online you can pick on this fact like crazy, but in a store there is no graph sitting in front of you.

The Fathom is $3500. If I could get you within a couple of dB or so of the maximum output of the Fathom @ 20 Hz for 1/4 that price, would you be happy?

Even so, I want to measure the Fathom directly. Anybody in the Chicago area want to drag one over to the shop for a ground plane test? I will definitely make it worth the effort.

Well, for me the main thing is the physical size of the sub. If you could get within a couple of dB or so of the maximum output of the Fathom @ 20 Hz for 1/4 that price in a similar sized box as the Fathom, then YES -- I'd be happy. Heck, I might even buy TWO!

Chad, not that you're asking for direct feedback and input... but as long as you're here, I did some measuring for you. Here are the perfect sub measurements for me (and probably others as well):

* No more than 24" high -- including the feet, if any.

* No more than 24" deep

* No more than 22" wide


EDIT: By the way, the MOST IMPORTANT aspect to me is the DEPTH of the sub. Any more than 24" deep and it "sticks out" like a sore thumb. The other dimensions are important to me, but not as important as depth.


Hope that helps.

SoundsGood,

Our single sealed 15 inch subwoofers (both models...) are well within those dimensions. Hopefully I can get some pictures up on the website by Thursday or Friday.

With the right driver, you can fit a pretty nice 15" sealed subwoofer into a 18" cube. Needs an LT circuit and a fair amount of power (~1500w peak), though. I look forward to seeing what you came up with, Chad. Are you including various LT circuit options in your sealed subwoofers? It'd be nice to provide customers with a way to tune it to match room gain, or trade off extension for output.

Well here are may good choices. You know you can place the subwoofer sideways. The driver doesn't have to face the listening point.

Mark Seaton's Submersive
24" D X 17.5" W x 24.75" H (plus 3/4" tall feet).

SVS PB13-Ultra
27 D x 20.5 " W x 22" H

JL Audio f113
19.25 " D x 16.50 ". W x 19.75" H

SVS PB12-Plus/2
28" D x 19" W x 26.5" H

Not in my case. It won't fit if I put it sideways. Out of that list, only the JL Audio f113 would work for me.

I gotta stick with the dimensions I suggested to Chad.

What about the 60-80Hz punch that the fathom/DD subs have? Or is this only a low Hz sub?

They've got plenty of punch in the 60-80 Hz range.
