Calling BS on "breaking in" subwoofers, prove me wrong.

Directly from DD website regarding the 9500 series woofers. People may question the build quality of AQ, but I hardly think people can judge the quality of DD (the price is a whole other story).

DD blows.. For one.. i recones my woofers with glue strait from their "vat" that they use.. glue did not set up with accelerator.. ****** glue.. ended up needing more recones.. number 2 the gap is tiny, the coils are thin, and made out of carboard.. **** man.. RD/atomic there is not a piece of paper or cardboard on the entire coil.. all aluminum.. and bulky.. DDZs are big subs.. but other then that they are behind in terms of competition.. daily beaters.. they are ok

Ah, my 9512s have been on 2 2500 sundowns strapped at 1 ohm for a year with no issues. Maybe its user error and not the sub. The afore mentioned shop that is nearby did a end of year blow out on their 9515s, because they were upgrading to the Z4s this year. I can post the video, although it does not show the initial abuse they went through.

After all the abuse, they were able to destroy 1. Also, this was after 2 full seasons of competing (including top 3 finishes at Midwest SPL nationals in several classes).

There is a pic of the 159.5(thought it was 159.6) I was talking about at 42 hz.^

I streetbeat 4 atomic subs on 4 d9s @.25 .. so what.. i didnt say they wouldnt play.. parts just arent as good..

90% of failures is due to bad/incorrect installs.

not to mention i know several people who work at DD.. i mean i live right next door.. one of them has helped me on my build some.. i know a little about DD.. not impressed.. but im speaking from a competition lets do 160 DB standpoint.. not daily do 140s

:laugh:

Doesn't DD have more WR's than any other sub manufacturer?

I can't believe anyone is trying to knock the quality of DD subs. Shows me lack of experience. They are expensive as **** though, one can talk about that all they want, and I will not argue.

Their Z motor does.. liek i said the Z is a beast.. after that.. it goes wayy down.. i see alot of 9500 series do well.. but at finals its all RD, Atomic, DDZ, some solo X, just an assortment of decent brands.. ill take RD all day tho..

DD owns most any other company as far as quality and record holdings. I'm pretty sure they lead the way on new and innovative woofer designs that are actually usable, not something just given a fancy name.

heres 26,000 watts to an atomic apxx... which is actually less then they are rated for.. do to atomics site and they will tell you 30k for burps and 25k for the apxs.. show me another site where the dealer says ya.. put 25k to it and its still under warranty... lol

ya they do own MOST

A lot of unnecessary bitching and moaning in here. The OP wants facts, point blank. Opinions don't count at all. A lot of unnecessary chatter from people who may or may not know what they are talking about, but your "break in" could be simply a result of other variables that your complete clueless to because you believe the subwoofer is "broken in".

Honestly though to debunk this myth, would take lots and lots of testing with many different woofers, multiples of the same woofers, different temperatures, different atmospheric pressures, ect.

Just out of curiousity because I have not attended finals personally? Where they the top of the line RD and atomic OR were they lesser models? I mean the 9500 may not hold up to the best RD or atomic offers, but what about their comparable lesser models?

the DDZ and the APXX have to be up at the top for baddest most durable subs.. if theres another i would liek to see it

i would put the DDZ and APXX necka nd neck.. the APX then blows out the 9500 and the atomic ele blows out the 3500.. im sure some dd nuthuggers willl say otherwise... but just froms eeing some of the setups, power they take, and numbers they do.. my .02

but the DDZ and apxx are in their own class.. just ridiculous amount of power it takes to even warm those things up.. gotta have a deep wallet
