I am purchasing a dd 9510g. it will be used for burps only. I was wanting some opinions on whether or not it was worth it to buy it with the stiff suspension and composite cone option. all opinions are welcome. thanks

If it's for burps only on extreme power. . I would say so. Or, if you plan on having enough pressure to cause cone failure.

I'm not sure that it would be considered extreme power. most likely to start with i'll have a memphis mojo 4kw on 14v on it. then when I get the 2nd sub it will be 1 4k on 2 9510s but I'm in the market for a new amp at the end of the year i'll be looking to put at least 7kw on the pair. the stiff suspension is my main concern now I'm pretty sure i'll do the comp. cones. the standard suspension on the new subs is extremely stiff now anyway. i don't know if it'll be worth it to go for the extra stiff or not

Xstiff spiders are only louder in a few applications.

I currently use 4 extra stiff and 2 mod. and they seem to do well.
Of course thier AQ HD310's and not DD but thier pretty much the same.

are the stiff suspension more durable over time? are there any applications where using them might decrease spl? I'm considering building some tubes for these subs, and I was thinking the extra stiffness might help in a tube enclosure.

yes if you are working with less power extra stiff will not work as well, unless it's a big box.

For burps only I would highly recommend composite cone, Carbon fibre dustcap and double XX stiff spiders on the 10. It will break in to approx where the X stiff would come new.

dunno if DD sells recone kits still, ( I need to find out asap for personal use though) but maybe if you buy 2x what you need as far as part just one with stiff one with not and test each sub in each different box you build will yield better results.
What I have learned though that anything that is competitive hobby you have to test and tweak on your own to find what works best... Even in the computer benching world people act as everything is g-14 classified lol Myself I am so good at it I reveal all my secrets cause I know even then no one will touch me with the same components (except a very select few) (sorry for bragging lol)

pretty sure DD still sells recones, but only for DD subs, not for making hybrids. So you have to have a sales receipt and serial number I believe

there will be no difference in SPL with regular cones vs. composite cones. SPL will be the same.
get stiff suspension and composite cones if you are giving the sub over its rated power, which is 1500 rms i think.
with lots of power the regular cone will fold.
get the big dust caps too.

I def believe the x stiff are more durable. I was always told that your sub will eventually decrease in output after so many burps and so much abuse. I live to beat the ...l outta my music and burped them I dont know how many times and everyshow they were just as loud or louder.
A friend of mine had these tens in a tube enclosure.8 spiders in ea. and they took 10k burps like a champ!

I doubt it. I wish I coukd but moneys tight and gas is high. bad combination for a tiny four cylinder pulling a lot of weight. I really want to go to one of the NC shows but I don't have a whole lot of extra time. by the way your prototype looks intimidating.........i like it. can't wait to see one in action
