I'm getting more and more ridiculous requests all of a sudden. This is seeming to be becoming somewhat of a problem, not for just us, but other companies that I deal with and talk to often.

We're getting a lot of service requests asking for average subwoofers to be built to handle absolutely insane amounts of power. While we're able to build some very very high powered subwoofers out of existing motors and frames, we are not magicians.

A standard "large" subwoofer with a 3" voice coil is NOT going to handle 3500+ watts reliably on a daily basis for most users! While there are some situations, and some users where this may be SOMEWHAT possible, 98% of the time, it's NOT going to happen.

A basic rule of thumb is as follows:
Most large 3" coil subwoofers can be built to handle anywhere from 0-2500w rms. These types of subs are like the RE MT, DD 9500, fi btl, IA Death Penalty, Nightshade, ETC. In some cases, we can build them to handle around 3000w rms.

Most smaller to medium sized 3" coil subs are going to meet their limits at around 1500-1800w rms. These subs are things like the DD 3500, RE SX, RD Alpha, etc.

VERY large 4" coil subwoofers can be built to handle up to 3500-4000w rms. These are the SS XXX, TC 5400/4HP, TRF, etc.

These higher power handling numbers DO come at a cost though. People ask me for a DD 9500 that handles 3500w rms and "kills on the lows". Guess what? It's not happening!!

By stuffing more spiders into the assembly to handle the extreme power and control excursion of the assembly, you're killing the low end capability of the subwoofer. You're making it greatly LESS sensitive, requiring even more power to get good output from it. Why would anyone want a sub that plays like crap from 40hz and down, just to pour 1000w extra into it and get the same peak output that they would have gotten with a looser suspension and les power?

Basically... when you ask me to do such a build, you're just running in circles. You want the sub to handle more power than it "really" can, and by us doing what we have to do to ensure that you don't destroy it in 5 seconds, you create a subwoofer that performs the same or worse on 3000w than it would have with 2500w or less.

Have you ever really thought about the performance gain from 2500w to 3500w? How much extra output do you think that you will get? In the real world, less than 1db.

This problem is happening because huge amplifiers are getting cheap, and it seems that just because people can run out and buy a 4000w amp, they think that a single subwoofer is going to reliably handle it. News flash... it cant!

While we want to honor your requests for extreme subwoofers, we still want you to be happy with what we end up building for you. Please keep this thread in mind when you send us a request to build your subwoofer.

We'll build anything that you want us to, but we CANNOT warranty a subwoofer with burned leads, ripped parts, burned or damaged voice coils, etc. These are all common failures when using subwoofers with too much power.

I'll be linking far fetched requests to this thread as a response, so if you post in here, make sure it's something helpful. Any silly responses will be deleted.

Thanks guys!

The sucker you out of your money part comes when I have seen on one occasion in the classifieds a sub was being sold buy " sub builder x " and said the sub was built to take 10 000 rms. On another occasion, another " custom sub builder" said his custom sub can take 7k rms.

How was the builder able to ascertain these ratings? Its not that hard to get a motor and assemble soft parts and make a sub. In my electronics class regular Joes like me did it in one shot. How do you know however, if you have set the coil depth correctly? or what the change in characteristic of the sub was obtained by using a thicker or longer coil?

A few guys have woofer testers, which arent hard to get; its around 100 USD, but I`m pretty sure when the sub is built, whatever parameters it ends up having are kept. No matter if its for better or worse. Why? Because the new coil can " take more power" and in the end, that one point is what those custom sub builders in Trinidad sell their creations on. POWER HANDLING

u ^^

becasue a man make a video name 5k playing a sub, it means the named sub handling 5k comfortably?

wtb a 40k amp and a 12 inch zebra then
and then put a video on youtube, for u to interpret

You saw the condition of frank? After all that abuse he lived

ok so OP if you can get a sub 15 inch company rated 5000 rms but cost about $9000 and weighs about 120 pounds would you buy it??

if you like privacy then stay home

The poster said before 'cusrom sub builders sucker you out of your money's

The hardest 2 single 15s right now are custom subs
the hardest double 15 right now is custom subs

And the mass quantities of xxx15s that Steve's were able to sell out, mass quantities of dd95s that Rrr was able to sell, the Orion hcca15s, some of the larger ground zeros, massive csx treos .. all these big power subs,

Who winning categories with them right now?

whoever walks with the biggest crowd.............

bring them under the meter and prove it
