New Sub Recommendations

no it wont sound bad. XXX wins. If you want arguments as to why the DD are not SQ well at least not in a lot of opinions. I can find them, but I don't really want to post them

1st off, 15's will not sound muddier unless they're simply poorly engineered or stuck in an improper box, which would make any sub sound like crap. Everyone always says "but the 15's cone weighs more so it's slower" or "but the 15 has to move more air, so the cone moves slower"....yeah, so what? If the cone moves slower that just means it doesn't move as far for a given transient, but it still turns around and reacts in the same amount of time. Transient response has virtually nothing to do with cone size or weight. You can double the weight of the cone on a driver and take response measurements and the transient reaction will be nearly identical between the 2, the only difference is the one with the extra weight has less output. This test has been done and these results have been measured and what I just said has been proven....just so you know.

I would go with the XXX, like I said DD's sound quality isn't exactly world renowned.

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)....both companies are good SPL and SQ companies.....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...


no offense, but you are also doing a 45hz tune for a "sound quality setup", which automatically voids any opinion you may have over what sound quality is and what actually sounds good.

^^ how many systems have you installed for other people? how many years have you been working at a car audio shop... maybe alot more than me or none at all but i checked my record last paycheck...38 installs BY MY SELF and a total of 102 over all...and how many of thoes customers have comeback complaining about overly boomy bass...none...how many have comeback for better woofers or more upgrades...many.... Bashing DD as a purely SPL company or not a good SQ company is like giving audiobahn praise for having highquality SPL and SQ woofers... i know DD sounds good and so does RE... and RE SQ isnt exactly world renowned either... especially the XXX series which, next to the HF series, is the most used SPL woofer made by RE...just as is the 3500 besides the 9100 and 9500 series...

Ever heard an audiobahn immortal box in a properly built box(not an audiobahn recommened one)?

^^ive herd audiobahns in about every set up you can imagine...its cheap $***...end of story... they can sound okay in a proper setup but if you are going mainstream and are thinking audiobahn just save your pennies a tad more and waste them on JL... or be smart and get the good stuff....

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. comparing a 9500 series to the XXX series is like comparing a JL w7 to a JL w3

u said it yourself. an xxx will rape the 9500 in sq. nuff said.

ya and... a 3500 will rape an HF in sq... because i also mentioned the HF... using either a 9500 or HF in an SQ setup is assanine

JL definately will beat them out, but a audiobahn built in a proper ported enclosure works well. Bahns are just marketed really wrong. Btw, I can go get the list of SI people and also P4s people who will agree on DDs as non sq drivers. Also the entire SI board will agree that 45hz is not SQ. You can not use the fact that you have done tons of installs to back up you know sq. Your average person you install has porbably never heard another system in their own car, let alone a sq system. Also SPL is usualy what your average buyer wants

I will go ahead and add the only quote that matters from the well known Lyod AKA Big bassman
"I've owned / used every DD woofer sold.. and every size brahma, and XXX

DD's get loud, and handle large amounts of abuse...

but sound like *** as you increase the volume..

however, you'll find some who think they are the greatest sounding drivers ever... course you'll also find people who like to have sex with corpses..

I wouldn't touch any resonance woofer for any reason other than balls to the wall competition..

an xxx has better sq AND spl than a 3500.
better and better.......hmmmm........is there really a decision here?

not only does the XXX not have a flater responce (they are enarly the same) but the XXX isnt as sensitive as a 3500...it will get louder but the SQ should be the same if both are set up correctly...but the 3500 is less expensive and dB difference will only be 2-3dB difference...barely reconisable to the ear...

Ok, Shut up. Do you know who Bigbassman is? He has been in car audio longer than you have been alive. I think he knows what he is talking about.

Wtf?

Well sorry I am just a little pissed you completely ignored my quote went and said you were right and then falsely state something isn't true. The 3500 is not a better sq driver then the XXX, read above. "I've owned / used every DD woofer sold.. and every size brahma, and XXX

DD's get loud, and handle large amounts of abuse...

CBFryman, you're wrong, give it up. The XXX has better sound quality than any of the DD stuff you keep praising, but if you want to get yourself subs whose SQ can't come close to the XXX, that's your business.

Lol, I'm gonna hook up 1 15" DD 9500 on Sunday and see how it sounds, I'll let you guys know how it goes...Btw, I'm more so looking to get loud.

:owned:

What you talkin about Haibane?

Does it matter what kind of port i go with, aero or slot? Will there be a difference in sq or spl?

What is this aero port you speak of?

oooo....that's a good idea, lets get into the "my penis is bigger than yours because I put a sub in some guy's car" argument :rolleyes:

The general public doesn't give a rat's ass about sound quality, I don't care how many people you did installs for, chances are less than 1% of them actually care about having a decently flat response and a good, balanced sound. And you have no idea what you're talking about with the XXX, it's one of the most well respected sound quality drivers there is. It has a very very flat response if you give it a decent enclosure, and it has less BL distortion than any sub I am aware of next to the Brahma and W7.

I think we covered that pretty well, but thanks for the "I am really pissed off response" lol

yeah you're right

I'm just a little behind, I was home for the weekend and I didn't have the internet, lol

Also another great sub that nobody is mentioning here are the Image Dynamics and Rockford Fosgate HE2's are rated at 750 rms i believe. These are VERY good SQ. Or any of the R.F. top end subs. All these are no more than 350 each. My friend has 4 10" he2's with 3000 watts in an Acura rsx. He hits a constant 152-155 on the streets!

Not only was this post long dead, but RF is nothing compared to the companies we where speaking of.
