Stainless steel gaurds, could loose it.

They handle very good I've had mine for almost 11years now and and they finally stopped working yesterday I don't care what nobody say bad about these subs cause they have served me well. Wish I could get 2 more cause they are really great sub. And I've had them in different kinds of sub boxes through the years.

Weakness the whole 11 years I did not find any they rocked hard.

Handles lots of different types of music, i listen to everything. For being in a sealed enclosure i dont lose them completely until 38hz

Im sure there are some but havent found them yet.

So ive had these for almost 2 years now. 2 15" 1200watt volfenhags in a sealed enclosure wired to 1 ohm beigbmpushed by an m.a. audio hk-1998 putting out 1200watt rms @ 1ohm.

I paid 200 for both subs enclosure amp and capacitor so i figured if i blew them i wouldnt have lost anything but they wont die.

When i first got them the previous owner had the gains and bass boost cranked way up. Typical but sounded like $#&*. Found the box they were in was falling apart and was no longer sealed.
Purchaced a new sealed enclosure and since these say they handle down to about 40 hz i set a tone and played with the gain until they clipped at 2/3rds volume of my radio and then turned them back so they werent clipping. No bass boost on on the amp and no equalizer set on the head unit.
This is key to any sub lasting and sounding good.
I run a kenwood dnx 7140 head unit so am able to set x-overs through the head unit. So i set the subs to handle 180hz and down.
I always got compliments of the sound from these guys and ive had my fair share of systems. My stock door speakers could handle the volume and the voice portion would become distorted so just recently installed 4 kicker 6x8's to compliment these subs and make the sound crisper all the way through.

The only issue i have had with these subs is that they will cut but thats due to my amp and trunk getting to warm and going into protect mode in the warmer months.

They are no spl maker but are a great bang for your buck. Im definitely thinking of going to a vented enclosure to tune them in for lower freq. But im more about the overall sound quality compared to making earthquakes.

techno music

rap $hitt

ok for all those people who talk $hitt about this German concept. This is a techno subwoofer. The thing plays at 15 000 herts. the average for a subwoofer is around 800. It is better to be put in a ported box and to buy a pair with around 200 rms running to each speaker but it really dosent matter. If you like boom boom this is not what your looking for. If you looking for a subwoofer that plays fast music and all the lows even the lower mids then this is the best out there.

price and value. have only impressed people since i have had it.

even when i give it the right amount of power I have still pushed it to where it maxes out on it's excursion and have to back off a little.

I am redoing my previous review which can be found below. So far people seem to either enjoy this sub or hate it. Many of the people who hate it have not given it a proper chance. I would like to tell anyone considering this subwoofer should not go with a sealed box because they suck. The best alternative is to go ported and tune somewhere between 23 and 30 hertz.

The worst part of this sub is that it takes a very very large box to make it sound good. Most people probably have not put it in the right box. At best it wants an 8 cubic foot box and at least 4 cubic feet. If going for the larger box tune to 23 Hz. You will get a pretty flat response all the way to 20 hertz. If going for the 4 cubic foot box tune to 30 hertz. It will not go as low as the other box BUT you will get really good output at 35 hertz.

If you want a sub that you can shove in a ready made crappy box then look somewhere else. The new shallow series from jl audio can be put in amazingly small boxes.

An alternative to having a huge box size would be iso-barik loading. You should look into this if you want great low frequency response. problem is it takes 2 subs for about the same spl and you need to power 2 subs. Good thing is you can halve the box size.

Volfenhag subs hit real hard but they are very over rated ive had my subs for two weeks and there already blown. I was only pushing 900 watts to two 15 inch 2400 watt woofers Volfenhag subs suck the big one

ok size magnet for cheap sub produced ok sound at low volume

red sticker glued to magnet. magnet plate glued on bolted only for show,easy to burn coils if not carefull no xmax movement at all looks like the sub moves 2mm before max out noise then very distorted. german concept made in china yeah never buy brand again better than sonys though wich are horrible.

broke in for a week when powered at 300 rms on rockford punch amp voice coils started burning. max out at very low volumes on certain bass notes only type box sound even close to decent was sql vented box. still even ive heard way better 1000 watt subs alpine e series sound wich are only 750 max each so volfenhags are seriously over rated.

many subs, bought this to mess around with

great performance as well as good looks.

none that i've found

I bought this sub after I heard a friend talk about them. I have never heard a sub hit with the clarity this one has. even mounted inverted I still couldn't turn it up more than half way before i couldn't handle the volume. ran it with a 1200 watt max 2 channel monoblock SPL amp. and you know power when your car becomes the box for the sub. had it for about a year and it still hits as strong as the first day i hooked it up.
