dd 9500 15"?

. if u plan to run 400-500rms on a dd9500 then why dont u get a 3500 series instead which will be better for the power demands mentioned. the sub should run atits optimum, ie. no point underrunning

why would the 3500 be better for lower power? will it "run" better? hell no.. its a woofer, they all do the same thing. the 9515 will be just as loud as the 3515 with 50 watts.. 500 watts, and 1000 watts, IDENTICAL!!!! The 9515 will start to pull away with power amount over 1000 watts.. due to LESS POWER COMPRESSION, thanks to the longer coil (i.e. more heat dispersion). You're completely incorrect saying that the 3515 would be a better choice due to performance. However, price would be an issue, but you did not mention that.

point 2 - from what i gather, Ricky Nichols does plan to use it fore SPL purposes, in which case, as i said before, lots of power, around 2000RMS per 9500 is a good number, not too much & not too little. and another thing, if u put a big amp up a sub, then u can turn the gain right down, u will have less distortion up to a certain point and the curent draw will be less too.

 

thank you.//content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif

wanna know how big a difference 300 watts is? (bd 1500's bench in the 1650-1700 watt range) bout .3db.. that enough reason to buy a new amp? not for this bassmonkey.. you can find .3db other places.

BTW... you do NOT want to turn a gain down a lot in SPL... distorted signals have a higher power potential, therefore.. they are beneficial to SPL installs. There is a limit to this of course.. you cannot fully clip an amp and expect a gain.. since you are robbing the cone of stroke...

thank YOU //content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif

wow i always knew bigbassman knew his stuff. ... lol.

i bow down before you...

if i were you jtmoney, i would listen to the WORLD CHAMPION! lol have YOU ever been a world champ?? lol.

dont think anybody can prove me wrong on the above and thats exactly my point. whilst i dont disagree that Lloyd does have some experience witn DD, I always go by the saying of a fool learns from his own mistakes, an intelligent person learns from the mistakes of others - i have seen and heard LOTS of DD installs & know what sounds good & what doesnt. explain to me then why Nathan Munson's ride had so many amps starpped to his DD and it coped just fine.

Nathan blew multiple 9515's at finals.. you don't hear about the woofers that get blown. I was there.. I talked to Nathan a bit, he tore up a bunch during his season. (I'm not including the woofers he purposely tore up in the PLD.) You should have seen the stack's of DD's at finals.... they aren't indestructable...

I have a saying myself, modified slightly...

Never argue with a fool.. they will drag you down to their level and trounce you with experience...

Yes I did.. it a previous post I shot in idea apart.. if you're competing.. and you turn the gain down... you're gonna lose...

I'm gonna down to SC for the weekend.. help a buddy get a pair of Brahma 15"s loud... hope everyone misses me.. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

another solution (im putting my system in your hands loyd), 2 1200 watt jbl amps on each sub thats like 600 bucks instead of 700, but would 2400 watts be to much, i will not have money to replace em if i blow one, and do those jbl's really push 1200, i mean 1200 for 300 bucks is a deal. , or stick to the rf

If this is for a daily driver I wouldn't do it. If you do,I hope you have one hell of an alternator //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 

[Ricky Nichols 10+ year member]

well i may compete sometimes but more of a dialy, my neighbor is an alternator shop and hes getting me the max they make (not sure about the ampage) , and im gonna have a few optima's and capciators

Cool //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I never ran that much power constantly to mine. When I tested the enclosures I would only run about 1500w a piece to em' . Good god was it still loud as h@ll //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

so will 2400 hurt em

 

[Wonderbread 5,000+ posts]

shouldnt, and for a dialy dtriver, jstu watch your gains, and they wont get ruined...

yeah that is a lot of power. i'm gonna be getting a 2nd amp of the one i own now that will put me over 3000 peak watts but i'm also gonna run them off a kill switch to where i can run 1 amp and sub at a time. you think that sounds like a good idea that way i don't go def or anything

keep it thumpin,

adam

 

[Ricky Nichols 10+ year member]

that is a good idea blazer, im gonna look into that. im already putting a kill switch to all amps in to one swith in the dash cus of my towns corny 100 feet law //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

 

[bumpin_blazer 5,000+ posts]

yeah austin has a 30 foot law so 100 feet is better than austin. but i've never been pulled over by a cop for my system (knocks on wood!) b/c i never turn my subs off during the day but i always do after 10. the law here is 30 feet before 10 and if they here it after 10 you get a ticket. that kill switch thing sounded good to me to though so now i gotta look into it.

keep it thumpin,

right....im not trying to get on anybody's wrong side BUT lert me spell it out one more time, for Lloyd especially......

ok....

1. 3500s are good for 1.2 kw no probs...1.5 in most cases and even 2kw IF YOU ARE CAREFUL. Daily driving numbers...not burps.

2. OK...9515 efficiency...this is where we get stuck...people think that because a 9515 is efficient it will be louder.

WRONG!

Only if it gets a bigger box...

It really does depend on the box, the power, alternator/battery supply, whether they are at their optimum voltage....you have to factor in a lot of things to get the right decision.

3. 9500s will work with anything up to around 3-3.5kw for daily use.

4. Power compression occurs when you reach excursion and thermal limits on the woofer...in the case of DD you will need more than 1.5kw to reach max excursion on a 3500, and way more for a 9500 - the cooling system on both subs is excellent.

5. THATS IT. I REFUSE TO BE DRAWN INTO ANY FURTHER CORRESPONDENCE. END OF MATTER.
