You've got up to $10K. What would be your choice for a pair of major subs. Two subs only!!

What pair would it be for sheer extension to the lowest frequencies and the most output to make your room shimmy with excitement where one Tripod's step from War of the Worlds would implode your theater!!??

Should be fun to see what folks think is best!

There are more than a handful of [op amps] that sound so good that most designers want to be using them as opposed to discreet transistors. Dave Reich, Theta 2009

2 Choices.

A. A pair of Revel B15a's

OR:

B. A pair of Rythmik servo D15SE's

Both audiophile 15" subs that use a TRUE class A/B amplifier. None of that crap economy Class D garbage they put in 99.99% of all subs on the market today.........

Wow, I guess that shows how amazing ID is. You give people a budget of 10K, and they post options around 2k!

Gotta love ID/DIY!

Jeff, for sheer extension, does anything meet or exceed the TRW?

I might go with a Seaton Terraform XL for deep bass and a JL Audio F212 Fathom for the mid bass, maybe.

What does class of amplifier have to do with anything? Especially with the frequencies we are talking here. I have used all sorts of amps on my subs and can not tell a difference. From a $10,000 Class A,AB to a $300 class D for my subs and the difference was null.

2 subs that dig as low as possible with max spl, Hmmmm, Thinking. Rotary sub will dig the lowest but how much is that thing? Dual DTS-10's will go to 11-12 hz with huge spl unless the room has a bad response. dual opposed sealed subs will not play as loud but coupled with a good room will dig deeper(needs good room and LT). What sealed subs has that much output? I had 8 sealed subs and during movies my dual DTS-10's hit just as hard(they are the eD drivers so LMS ultra drivers will be louder). I did not measure max spl just what they hit calibrated the same during movies. The Seaton terraforms look nice but I am not sure the tuning and spl capability. JTR is coming out with the orbit shifter which looks like a monster.

Sorry, but to sum it up these would be my choices.

Dual DTS-10's
dual Terraforms
Dual orbit shifters
as many dual opposed LMS sealed you can afford(or the Mal-21)
Rotary sub but that might exceed budget

AVR-Yamaha A830
amps-5 Adcom 555 in 850 watt monoblock mode
sub amp-Sanway FP14K
LCR-Dual stacked BFM DR-250's
Surrounds- Dual stacked BFM W10's
subs-12 SI 18's ported 6hz.

Rythmik is ID, Revel is anything but.

Regardless, THe typical retail MFG's have a higher price because your likely paying dividends to dozens or hundreds of employees, warehouses, mfg facilities, office space,packaging, advertisement,distributors, end retail stores and even the salesman's commision. The product itself costs at most pennies on the dollar to make. Its a joke.

I mean lets be real here. What is a "subwoofer"? Its basically a driver, an mdf enclosure and a mass produced plate amp. Take for example a top of the line Rel sub that retails for around $10k. You think that sub costs anywhere near even a grand to to produce in components and materials? Your dreaming. If I was told the total cost of the raw materials and components was near $500 I would be shocked..............

Last I saw the TRW-17 is still north of 10K for a single, but it would no doubt dig deeper than pretty much anything else.

For commercial choices, I pretty much agree with MK, and since he threw one diy option in I'll add one as well. A pair of ib manifolds with 4 Mal21s each. I realize I'm kinda cheating the question since it's only two subs in terms of location, but it's what I'd probably go with if I were spending someone else's 10K.

Class D subs tend to have muddy sound and have limited bandwidth. Class A/B amp driven subs, though not as efficient tend to blend better into the midrange with alot more resolve and detail. Even though the sub is playing from 20hz to 40-80hz before the lowpass filter is applied, there is still significant midrange information played through them. And Class A/B driven subs I find have a more seamless blend into the main speakers than do Class D driven subs with the exception of some of the servo/dsp driven units.

Well, if I'm taking looks into consideration, I'd have to go with dual piano black Sub 25's. Those subs are drop dead GORGEOUS! If not, anything on MKtheater's list above should do the trick.

I doubt the subs being clearer was due to the amp. The servo keeps distortion down so they would of course sound cleaner. The sub itself was better overall. What I am talking about is using the same sub but just change the amps out which I have done several times making the only difference the amps. The difference is just not audible when doing that. Saying one sub is better than other because of the amps is a stretch, I bet the driver and cabinet was better. Like I said I have used Class A, A,AB, AB, and D and for subwoofers the difference is not noticeable on the same sub. Just take a look at the amp thread in the DIY forum, even the cheap Behringer amp can play a sine wave at 850 watts into 2 ohms at 20 HZ with .01% distortion, that is very clean and powerful. It can do the same at 1khz.

Are you sure since not many has even heard this thing? Remember, thebland wants a sub that can play low frequencies at high spl's.

Jeff - For your budget and needs, drop Kevin Haskins an email at www.diycable.com and ask him about getting a pair of dual 21 inch Maelstroms (4 drivers total) built for you.

Outdoors at one meter, with two 20 cubic foot boxes and 3000 watts each, you are looking at 118 dB at 10 Hz, 128 dB at 20 and 134 dB at 40 Hz.

The drivers are about $2500 for the 4, leaving a nice budget for amps and enclosures. Kevin will help with the whole project - this is not DIY, it is custom.

Give me a single DS1500 kit and 2 sheets of MDF and I'll make a sub that puts the Danley kit to shame for half the price no less. An efficient 15" driver in a horn loaded cabinet is pretty easy to do.............

Good luck with that one, so you are telling me that a horn sub(tapped horn) is easier to build than a sealed sub? A sealed sub has to be the easiest enclosure to make, I even built 8 of them.

BTW, put to shame in what way? Besides your unproven opinion what facts do you have to make this statement.

Again the OP said lowest and most spl, a single 15 in a sealed enclosure won't come close. Sound quality will be subjective and vary from user to user.

If you can build a better horn sub that can go to 10hz be my guest. The dual 12's in the dts-10 are beast and efficient themselves.

BTW, if you can build a tapped horn that goes to 10 hz with as much spl and low distortion with the midbass impact they deliver I will build it myself and buy the plans from you. I would need the plans. Maxmercy is trying to do that himself but anything that even gets remotely close to 11 hz with a 15 or larger becomes much too big. Even if it performs the same I would still buy it.

Horn loaded, tapped horn, folded horn, multihorn enclosures really arent hard to build or design. If you got the room for one, they will have extreme output.
