HOLY SH**!

It's back!! Wine of the Week! Clos Martinet Tinto, Priorat DOCa, Spain ~$60. If you've not had a good Priorat, you've not truly tried Spain's smallest, yet most unique terroir.

Anyone remember the toy vibrating football games as a kid?

I would say it's gotta be something like that!

Cool, but I wouldn't want to be in the room when he cranks it at 10Hz - any frequencies below about 20Hz at high intensity can make you very sick - or worse. The Germans built (and tested, I believe) such a low-frequncy weapon in WWII!

I remember seeing this at HTF.

Horns are very impressive but they take up too much space..especially in this particular case. Whoa! http://www.avsforum.com/ubb/smile.gif

This page keeps floating back up every so often. Very impressive work, and I can't argue with that sort of ambition. With that much space available, I personally would be looking at some other options that would have been a LOT easier to construct, but to each his own. As for some of the comments made above, some are rather ironic given that just last night I visited some friends over at Servodrive/Sound Physics Labs...

First to dkeller_NC, obviously you haven't experienced bass repoduction like that as in fact it is quite enjoyable, and makes it hard to hide the big grin it brings to most. Last night I again had the opportunity to briefly play with a PAIR of Contrabass subwoofers. These are FLAT to 14Hz, and can produce 116dB at 16Hz. Yes, they do music, not just produce sine waves, and were damn impresive on any of the music I had at hand. I had a chance to play the Telarc sampler "Jurassic Lunch" and I determined I NEED to get these in a real theater system to just experience them properly. I've been told the depth charge scene from U-571 is something to experience with these. For those who aren't familiar with the Contrabass, here is a link with some info.
http://www.servodrive.com/servo/cb.shtml

On a mildly related issue, pronkie-uk mentions canceling out earthquakes. While not that ambitious, yesterday I read an article outlining how the Servodrive Bass-Tech 7 (the original DC-servomotor driven cone speaker) and the Unity TD-1 loudspeakers will be used for real world noise cancellation... to control the sound of commercial jets at an airport runway! Mind you to cancel sound, you need to generate nearly equivalent levels, and the acoustic consultants involved found the BassTech 7 and the TD-1 the ONLY products to actually meet the specs they had determined neccessary to accomplish the task! And to think I'm putting a relative of these horns in my home system http://www.avsforum.com/ubb/biggrin.gif. Fun stuff, and again, there is NO problem at all with having 14Hz extension, and in fact, Tom Nousaine, noted subwoofer reviewer, constructed his personal home subwoofer which is capable of 120dB at 12Hz. The big problem at this sort of extreme is keeping items in your home in one piece if you ever decide to realy see what it can do.

Mark:

Having the capability to output 10-15Hz isn't the same thing as doing it - very few DVDs have such frequency information, and not at high levels at that. Regarding the low-frequency weapon, several non-lethal force companies are developing low-frequency devices as a means of crowd control. Granted, they are designed to ouput 10 Hz at 100 db, which is extremely high intensity.

How about this Kharma Grand Enigma system:
http://www.kharmausa.com/sPECIALPRODUCTS.htm

The bass drivers on the left and right of each speaker are actually horns that goes to the other end of the speaker(left woofer of one speaker connects to right horn of the same speaker, vice versa.) With an efficiency of 100dB/1W/5M.

Certainly nothing beats the efficiency of horn enclosures.
However the transient response of low frequency horns
is pretty lousy.

Much better is
http://www.wilsonaudio.com/products/xs/index.html

and tuned helmholz resonators like the jensen design
from the 1950's work well too in a much smaller space.

4 big JBL 4645C with 1500w each will do for me, 2 already stacked. http://www.avsforum.com/ubb/smile.gif

thanks for this link, incredible. there are some bass freaks on Earth....... http://www.avsforum.com/ubb/smile.gif

but the new SS SVS should rock the industry. the KRELL (2x15", 2600) will have some competition.

for cinema sound in your HT, use cinema speakers and cinema amps! unbeatable.

It's all about headroom! It's one of those cases where you know you will never reach the limits of your system. Live music has very short term dynamic peaks that can be very significant relative to the average level. Cleanly reproducing those peaks (when they are actually recorded and not compressed) goes a long way towards a better sense of reality. It is a lot like deep bass reproduction... until you hear it done right, you probably won't miss it. Once you've really experienced it, it's addictive http://www.avsforum.com/ubb/biggrin.gif.

Oh boy, I thought I was out to lunch with a couple of 18" subs. This has to be a real danger in the wrong hands.

Hi Kevin,

I hadn't noticed you here before (did you ever get that D-ILA you were looking for?). I would agree, the XS is a great example of what a REAL subwoofer can do. Interesting that a single Contrabass is half the size, and can equal or better it's output at the bottom end. Admittedly, at the top of the sub range, the dual Aura 1808s gain some headroom over the Contra', of course that's what 2 are for.... at well under 1/4 of the price. http://www.avsforum.com/ubb/biggrin.gif In any case, it is always nice to see some acknowledgement of the sonic payoffs truely deep, and clean bass response can give a system.
