Will subwoofers be getting any better or just bigger? Also, will there be a point soon where subwoofers cant be improved any more? I dont want any super hi-tech posts Im just asking as far as new stuff coming out but if you must post the brain juicers than go ahead.

not really. maybe in new cars with the new 48v electrical system. but that's about it.

sure they can get better.

But I don't see by how much. There's still the physcial limitations of
enclosure size
power handling
depth

you can only be good at two, the other will have sacrifice.

there are new servo based technology subs that are pretty darn incredible.

I just want to see what Alpine comes out with next because I had one of their 12 inch Type R's and loved it so bad that I had to sell it on Ebay. No really it was awesome!

Bigger is better.
There is no way around it - sound is the movement of air, so subwoofers are absolutely limited by the "swept air" movement of the driver ( Surface area x driver movement)

The response time of the magnet and cone are a factor too in producing louder, deeper, and clearer sound.

meh, make me a 20 foot by 20 foot electrostat or planar subwoofer and I'd be pretty happy.

nope. that is all mumbo jumbo.

You can trade in some low end response for a slight increase in efficiancy with a ported enclosure, but how loud and how low a driver plays is governed in absolute terms by the volume described by the area of the driver multiplied by the X-max.

More cone excursion will get you more air as well. Notice that a lot of subs these days are coming with huge surrounds for a LOT of excursion.

Ideally, the perfect subwoofer would have no mass (high efficiency and transient response) and completely rigid (no distortion due to cone flex). The closer we get to those two ideals, the better things will sound.

Mmm... Martin Logans... :) I heard some of their "low end" speakers that were only around $6k for the pair. I won't go into details on their sound, but let's just say it was a good thing I was wearing brown pants! :Q

you have that link to the folded horn sub they built under the floor out of concrete?
 

yes, they can and will

one of my best friends is a speaker engineer at one of the big name car audio companies

he currently has 2 'test' subs in his car - they REALLLLLLLLLY pound, much harder than anything i've heard
they'll be on the market next january (launches at CES i believe)

i cant link you to a 20'x20' but maybe a 24"x24" sub

http://www.adireaudio.com/Files/Dan/Parthenon/

and yes, subs will be getter better, and bigger.

The XBL^2 technology is amazingly sweet, as is what JL has done with the W7, people will be trying to break that.
XBL^2 allows the sub to stay straight through more excursion i do believe

Also, you then have the RE MT which is setting records on the DBdrag arena because RE researched the hell out of it, and then made it work like crazy.

for pure loudness maybe, but there are other factors to speaker quality. Frankly, top-notch speakers are usually wasted in most home-user applications due to the shape of the room/car they are used in. It doesn't matter how good your speakers are, if your license plate starts to rattle it sounds like absolute CRAP (which describes the music preferences of many of the people who cruise around town at 3 AM blasting their "music"...)

Cheers!

Hm. Got goosebumps but no chandelier hanging from my Senheisers. Time to get an amp I guess. Be interesting to listen to this on my old crappy headphones ... :23 - :40 probably sounds like silence.

BTW, this is a very interesting solution:

Servodrive ContraBass

It uses a servo motor instead of the normal driver.

More:

BassTech 7

They have a new folded horn bass unit called the SPL-BDEAP32 too.

BTW, spidey07, you're talking about the Royal Devices sub?

http://www.royaldevice.com/custom3.htm

yep. That's the link.

I really think the servo tech is a step in the right direction along with auto-eq.

True. The room is you're biggest factor.

But IF a sub isn' capable of the frequencies desired in an anechoic environment it would be awful hard to make it produce them in the gnarly spaces of a room/car.

Nope.
Bigger is better for subs.
Better response, better transients, you name the spec., and it is better as "swept air" increases.
