Lol, yeah that piece of trash they charge $2500 for can be outdone by a 10" woofer

I'll see your Fostex and raise you a Back to the Future subwoofer... ;)

10" ? Can you show us pictures and spec ?

If you really want to know what the mother of all subwoofers is, the Thigpen Rotary. Too bad it will set you back about $13,000.

we need to hear from some Danley owners

Nothing but the Eminent Technology TRW-17 can do over 110 db at 4Hz in a real room. If there is anything from Danley or anyone else that can do over 110db at 4Hz, I would like to know what it is.

Here are some starting points.

The owner of that concrete subwoofer can't even measure the response at 5Hz. This is not about car audio. We know that at certain frequencies car audio can do about 170db.

what's the WAF on that sub? :eek:

So those guys go through all the trouble to design and build a 60" sub and then it's shelved without seeing exactly what its capable of? :rolleyes: (other than hitting 162 and breaking)

the TRW-17 is hardly "plug and play", imo it's more of a DIY type project

at 2k shipped the big ED monster appears to be pretty high on the mountain

You are right, the TRW-17 is not a "plug and play" subwoofer. The TRW-17 is for people who have a lot of room and a lot of money. People who have been to demos of the TRW-17 know that it is the only subwoofer than can do over 110 dbs at 4Hz. The big Ed monster is high on the mountain from about 10Hz on up. However, the Ed can't begin to do 110db at 4Hz.

There is nothing (else) on the commercial market that can do over 110db at 4Hz. The very highly regarded Epik Conquest could do 103.9db at 12.5Hz.

There is no "plug and play" subwoofer that can do over 110db at 4Hz.

If I could reach you from here, I could shake you at much more than 110dB equivalent at 4 Hz. But I'd have trouble with 20Hz.

My car wasnt even built for SPL it was done for SQ which got a 9 out of 10 for overall SQ. 600 watts rated toal for both subs and only the 302 even ran the subs, I had 2 USD 12".

I’ve seen it before last year:D. and that sub is not real its “fabricated” I mean would the air from that really lift the body off of the floor and propjet Marty flying though the air like that. I don’t think so, the distance looks around 14 feet.

The ionised magnet structure alone would weigh a ton or so and would be so damn powerful it would interfere with any other electronic equipment in the home.

I saw that episode as well and if I remember correctly did they not weld the "slices" of the metal sub together? Not the most flexible solution but using the crankshaft to "power" the sub was a pretty cool idea.

The Epik Conquest and the Ed A7-900 are probably the highest output commercial plug and play active subs right now.

There is not much interest in passive subwoofers right now. The SVS B-4 may be the highest output passive sub, however, it is out of production.

The real mother of all subwoofers is the Thigpen Rotary.

If the instalation cost of Thigpen Rotary is about $25K, how big is that FAN actually? :eek:

I have a dedicated HT of 17' x 24' ceiling 10'. Is the Ed A7-900 with its 1,500 watt amp not overkill for my set up?

Damn that matterhorn thing looks cool!

Spyboy, how many movies actually have any content near 4hz? iirc, the guy on the forums with the thigpen sub commented that very few movies benefit from the thing (or something like that)

If the guy on the forum did not get a lot out of his Thigpend Rotary, why did he end up buying 2 of them?

Deep Bass is a funny thing. I have had several guys sitting all of one foot from a pair Fathom 113's, and we were talking. I ran a high level, 12 Hz sine wave through them - and I mean they were RIGHT behind the chair.

They were delivering 100 dB of SPL right at the chair. Not one person knew they were on.

Of course, after being TOLD they were on, and what they were "hearing", each guy suddenly was able to tell they were playing.

That's the Grateful Dead, Probable the biggest bass heads ever. Anyone that saw them in concert would agree. They used to play trains and thunder during intermission just to shake the place up.

Holy Crap! $145,000 for a subwoofer? Is this for real?

Yea a joke for real...:rolleyes:

These Me Too companies with these hocus bogus claims are pathetic. For $30000 you can probably order a custom woofer with a 250lbs motor structure and probably made with the help of TC Sounds or another reputable company.

Over $100000 for ONE driver is just plain dumb,these drivers are primitive air pulse pumps nothing more. No rocket science in there.No long research needed,the technology is all here,even CAD to help design them.

If anyone buys one give me a call and let me unload some compliments to ya.
For wasting money like a an challenged oil Sheik.

Then again with the capability to do 120 db at 20 hz at 750 FEET away...you could pull the trailer up to the back of your house, cut a hole in the wall, hook it up and demolish your house. Bet the Thigpen can't do that. :D

Has anyone seen the youtube vid of that chick with the glass eye in the car at some bass contest type competition.... The guy turns it up and i'll be darned if her eye didnt pop out!!!

10" ? Can you show us pictures and spec ?

Sorry, this is from a while back. If you look at the parameters of this driver, it isn't hard to understand just why it is so horrible, it has a huge sd, which normally is good, but at this size, its impossible to control the con breakup at subwoofer frequencies, let alone woofer or midwoofer frequencies where the driver must be designed to perform, this will give the driver a very high distortion and peaky frequency response. Secondly, it has the highest vas of any commercially used driver to date, and this by a LOOOOOONG shot, most suitable enclosures for this driver are in the hundreds of cubic feet, making the only suitable scenario a open baffle dipole. Now let's look at the vd of this driver, you would think that with a third of a meter of surface area, it would be able to push a LOT of air, however, the measly 2.3mm xmax puts this woofer back in the running with much smaller drivers in terms of total displacement. It only sweeps 1.5liters of air, a 15" dayton RSS390HF sweeps 2.2Liters of air, and costs $160. I chose that woofer as an example because it could at least beat the midrange performance of the fostex mammoth, however, by comparison, a Soundplinter Rl-p18 will sweep nearly 7liters of air and they cost $420 and can be put into reasonably sized enclosures, the fostex is starting to look like the whimp it really is. Now, if nothing else, you would hope that driver of this size would have some insane efficiency, but at 96dB, it is pretty normal for PA woofers. Speaking of PA woofers, let's look at what we can do to accomplish the same goals as the fostex. how about 4 simple 15" drivers, all they need is 90dB sensitivity and 2.3mm xmax to match the performance of the fostex, and I guarantee you they would cost WAAAAY less and be able to be used in tons more flexible alignments. If you wanted to destroy the fostex, how about 8 lambda woofers with the apollo upgrade, they have flat response to 5Khz and will sweep 13x the air, have twice the cone area and cost the same as the fostex.

How about 180.1 db from ONE subwoofer?

This is a picture of my buddy's Avalanche. It's running around 10,000 watts to 8 15" subs in one ported box. It out puts 168db. Not home audio but definately the loudest thing I've ever heard or felt.

not putting down the Thigpen Rotary as I have never seen or heard it, but it sure does look like a fanA fan with the ability to maintain it's rotation speed while varying the pitch of it's blades in a very exact manner. This sub is optimal for <20Hz operation but it won't operate at higher bass frequencies. In other words, it's used to augment an existing bass system.

As far as off the shelf units, the Everest subwoofer by Acoustic Visions (http://www.acoustic-visions.com/~acoustic/products/subwoofers/pre_finished/pinnacle_everest.shtml) is capable of a lot of output (amp not included). Off the shelf products tend to be limited by the size of the enclosure and weight of the unit (shipping and inventory storage would be prohibitive for most companies). This is one of the reasons why DIY subs are very popular (stick a 15" driver in a water heater and you've got great performance, etc.).

KyleLee, it is an 18".

I stood in the horn mouth of the Matterhorn at a tradeshow in Anaheim, CA while Tom played a 5hz test tone at what he called 5% of the equipment capacity and I became sick to my stomach. It was insane. You felt as if bad things were going on in your body. Truly intense.:)
