New Sub Recommendations

[KMoney28]

Alright guys, hopefully this will be my last question on this topic. My friend offered me a Digital Designs 15" 9500 series sub(DD9500e) http://www.ddaudio.com/dd/caraudio/w...p?series=9500e
for $350. Any thoughts if one of these with my availble trunk space will hit hard? Is this sub comparable the the XXX15? I'm still racking my brain because all I've dealt with is 12's and always more than 1, I wanna be absolutely certain that 1 15" will hit just as hard if not harder than multiple 12's before I make a decision that I can't go back on. Thanks a lot for all your guy's help. So, the final question is 15"XXX, 15" Digital Designs 9500 series, 2 12" XXX's, or 2 12" Digital Designs 3500 series, and why?

I would still get the 15 XXX

believe me output won't be a problem, let me put it this way. A friend of mine has a pair of 12w3v2s on a 500/1, and my single e12a on 800x1 easily smashes them in output (according to both me and him, his jaw dropped the first time he sat in my car). The XXX will have nearly twice the displacement and twice the power of my 12a....

Whichever setup I go with, I think I'm gonna need new interior speakers. I have some aftermarket ones right now but they're not the greatest, Sonys in the front and Pioneers in the back (can't remember the models of either). I also have a small Pioneer 4 channel amp(like 300 watts peak I think) for the 4 speakers. My question is should I buy a better pair of front speakers and bridge the amp to just those two and take out the rear speakers? Would I have enough highs and vocals from just two front speakers? Any recommendations for nice front speakers? I need 5 1/4 in the front and am looking to spend no more than $300 for a pair, possibly with tweeters. Also, would removing the rear speakers increase bass response, or is it a bad idea because the music will suffer?

CDT www.thezeb.com
I run the EF61Cfs and have never been happier. You don't have to spend that much money though

[KMoney28]

Thanks Haibane, I'll look at some CDT 5.25's. Will 5.25 CDT's amped be ok if I remove the rear speakers, or should I leave the Pioneer 6x9's installed in the back?

[Haibane]

Make some kickpods if you can and run 6.5s amped. As for if the 5.25s will be fine amped... depends on model. If you are talking coaxial go ahead and leave rears. If you are talking comp, do you want good front stage? if so nix the rears.

Digital Designs itsself isnt SPL oriented...they just give the customers what they want. The 3500 series is a tad bit less than the XXX series price wise...about the same SQ (depends on your ear really) and 1 XXX will be a tad bit louder than one 3500 series of the same size...but since the 3500's are cheaper its expected for them to be a tab bit quieter... both Resonant Engineering and Digital Designs are great companies... IMO they go hand in hand... Neither company brags about how good, just how loud, but both companies are good SPL and SQ companies, both win about the same amount of SPL competitions and SQ competitions...and as for the 2 12's v. 1 15....it all depends on how much room you have....since 2 12's have more cone area they will need more air space and will more than likely handle more power than 1 15....most people will be happy with either.... i personally would like 2 15's lol... takes a good mid and high to keep up with 2 12's lead alone 2 15's....if you only have 3 cuft a XXX 15 or 3515 will be great... but it will take alot of power to feed either.... of corse it would take just as much to feed 2 12's...its up to you...go listen to someones system with 2 12's and then go listen to 1 15.... the 15 will be a lil muddyer but not much if it is a good quality woofer...i think you will be very happy with either ocmpany and either size woofer...but like i said if 3 cuft is all you have then 1 15 will work well...yo uwil lactually ned about 3.5-4cuft of space since yo uwill then need calulate in port volume, enclosure bracing, and the wood you make the enclosure out of....if 3cuft of space is all you have period you mught think of going sealed or only have 1 12'' ported...

a 9515 for 350....either he played the hell out of it and it is about to go, yo uare getting a very great deal, or it is very old...its probably #1...the 9500 sereis is in no way a SQ oriented woofer...thoes are the woofers DD uses in the teams that go to and win world SPL competitions under the monstor class.... it is equivelent to the RE MT series...comparing a 9500 series to the XXX series is like comparing a JL w7 to a JL w3

I have a few problems with some of the things you say like...
"the 15 will be a lil muddyer but not much if it is a good quality woofer"
Not necisarily true. Many people assume that because a 15 has more weight which is believed to slow it's movement down, but I believe that an 15 inch XXX could keep up with a 12. It depends how it is built.

also...
"since the 3500's are cheaper its expected for them to be a tab bit quieter"
No. I don't expect an XXX to be quiter than a W7 just because it's cheaper

"both win about the same amount of SPL competitions and SQ competitions"
What's that based on, have you researched every compitition they have been to... didn't think so

You contradict yourself a number of times, for example...
"since 2 12's have more cone area they will need more air space and will more than likely handle more power than 1 15"
"if you only have 3 cuft a XXX 15 or 3515 will be great... but it will take alot of power to feed either.... of corse it would take just as much to feed 2 12's"
Pick one big guy, you can't say both
A 10 inch XXX takes 1600RMS as does the 18 inch XXX so obviously, same for the 12 and 15. How can you say it would take just as much power to feed 1 15 as it would to power 2 12's?

I don't mean to argue, well maybe a little, but I have read alot of the things that you write, and much of it is wrong.

[CBFryman]

your not getting what i am saying...i am saying that 2 12's WILL be louder than 1 15...but a 15 will be pretty loud... comparing JL to DD or RE is retarded... JL is good quality but they over charge...that has been established time and time agian... the guy who asked the question obviously isnt seasoned stereo installer so i was telling him why a XXX is slightly more expensive than a 3500... if i where to tell him that they where the same he would be like WTF and immediatly buy the 3500...but since the 3500 IS NOT as loud as the XXX but is still a very good woofer...and why dont you go look at some dB drag results over the years...4 companies that dominate... Kicker, Audiobahn, RE and DD...kciker and audiobahn only because they ARE SPL oriented and have far more resources money wise than most teams using DD or RE since teams using DD or RE dont get full factory sponsorship....and as far as SQ...when you have herd as mand systems as i have yo ucan tell what woofers sound like what...but my deff of SQ may be diff from yours or anyone elses...i have also said that DD and RE use the same motors on all size woofers and there for have the same powerhandleing where as other companies sacrifice sensitivity in the larger woofers motors for greater power handleing since larger woofers automaticly have better sensitivity since there is more cone area to move with the power provided...the XXX series and the 3500 series will take alot of power...but in order for 2 12's to make the same readings as 1 15 the 2 12's wont need as much power...i dont base how much power to put on a woofer on its maximum power handleing...i base it on what will sound the same compared to a different woofer or number of woofers...its like 1 12 with 1000w will be just as loud as 2 12's with 500w... as far as 15;s being slightly more muddly than 2 12's....this will always be true...the larger surface area makes the woofer more sensitive but also makes the motor have just that much more air to push...the difference will be so minimal in some cases that yours an my ears cant tell at all but it is and always will be there....

[Haibane]

kicker and audiobahn dominate? Been to a big car show lately? Most the stuff I see is RF and audiobahn... I rarely see kicker as much anymore.

[CBFryman]

^^^or kicker used to dominate... :-/ they would be great woofers if they were a tad more sensitive... even the comp CVR's will move some air if you get enough power on them to get past that ultra over rated sensitivity....

[Haibane]

cvrs are fun. Bahns Qs sound much better IMO

[KMoney28]

In refernce to the DD 9500 15". He's selling it because world finals for db drag are coming up and he wanted to get it reconed to an 18" but decided it was more economical to just buy the 18's. The subs are only 2 months old and have only been used for competitions. I want the sub strictly for music and street beating, not competing. So the grand finale of this question, 1 DD 9500 15", or 1 RE XXX 15"? 1 15" won't be muddy or sound like ass right?

[CBFryman]

neither sub will be muddy or sound like ass...if you have the money to buy the amp to power the 9500 all power to ya....it'll be so damn loud any sound difference between that and the xxx 15 wont matter.... i still vote 3500 but since your final question is 9500 v. XXX... id say the 9500 if you got the cash to buy the power with a clean amp or if yo udont just buy the XXX....i geuss yo ucan say im a DD head.... lol
