Im getting ready to put a small system into my 2005 350Z. Im running 2 JBL amps at 424 watts each at 4 ohms.
I'm not a boomer but wouldn't mind showing off clean loud bass to some young punk if needed. Since space is very limited and both subs recommend 1ft3 each, should I go with 2 8" DD 1500 series or 2 10" Alpine Rs?
Thanks Sam

The pair of 10" would definitely impress young punk, because of the cone area. On the other hand the dd 8" sub would probably be loud too but just depend on the enclosures, amp, and type of install. Since room was concerning you then go for the 8" sub.

oh really? why will be DD be better? it is smaller..rated less power...smaller voice coils, you cant choose voice coil resistance (alpine have 2+2 & 4+4 impendance) , and alpine has better frequency response- goes lower...I had two of dd 0512 in ported box....around 90 liters of volume and they didnt get low...however I tuned the box...for everyday listening alpine is better...dont judge if u dont listen this sub in proper box...I have listen alpine R & X series, and dd 05series, 35, 95 and 99...and alpine for short burps can handle more power (comparising 1500 and R series...)

Wow. Do some research, DD 1500 series are available in dual 4 and dual 2. Also take build quality into consideration.

I did take and if to U dd sounds better than alpine...you have hearing problems or U didnt ever listen to the music...only the noise....build quality? why alpine isnt quality builded? or better...why the DD are?? and I believe the man want to listen something, not to look how the thing is builded or made
BTW: i have told the advantages of alpine...U didnt told the advantages of dd...

I will.........the 1508's are stone cold bad ass subs. they will tune at 20hz if you want and they are small .75cu per sub with port. I have personally tested two 1508's in a ported enclosure and read 161db in the port. In my opinion two dd 8's will out perform two alpine 10"r/s every day of the week.

The "advantages" you named are 1. The type R 10 is bigger ( you're absolutely right a 10" is bigger than an 8" sub ) 2. Higher rated power ( right again even though this rating doesn't mean much and it doesn't really matter considering he will only be giving 400 watts to each sub and both will easily handle that ) 3. Smaller coil ( once again 400 watts ) 4. No choice in impedance ( Wrong DD 1500 series can be had in dual 2 or 4 ohm) 5. Better frequency response ( this sounds like an opinion so some will agree some will disagree)
So, the only real advantage is one is a 10" one is an 8". I think everybody reading this already knows that. Thank you, your input is much appreciated.

Once again I appreciate the input and apparent passion for this topic, but it occurred about 2 weeks to late.
I already received the two DD subwoofers from the factory.
I will be building an enclosure according to the manufacturers recommendations because thats how I do business and I see DD added a .75ft3 enclosure design for this sub giving me greater flexibility.
Thanks and peace out

I think the alpine is better choice...and they will go lower....and deeper ( even that dd's are 10" too) ...in my experience with DD's 05 series and alpines...and tuningof 8" woofer to 20Hz?? you will her that?? because i dont....I can maybe feel it..but hear it no....and why will I tune sistem so low?? i didnt see (hear) a song that goes beneath 37Hz (except burp tones and some bass tests) and i have no need to tune system that way....especially with 8"s... that 18" is in question...33Hz is lowest that i will tune....and by the way...we are all speaking about subs (speakers) specs...but I believe that will be more important how they sound...and i believe that alpine will sound better of 1508s....as I sad before...i couldnt make 0512s to go low and play deep....for drag DD yes of course...95/99..for listenint...they are ****....anybody says different...he didnt hear real sq music..and DD for playing some music needs huge boxes....**** that sub....

and by the way....everyone says only good things about equpimnet he represent or use....no one will say that equipment he bought and payed a lot of money is crap....I can say so...so i say..in my experience DD is crap for listening...unless you are listening to the noise...and interior noise of your car...

everyone has their own opinion, I didnt say i would make a box to go to 20hz i said that they will play that low. Congrats on that 151.1 db nice score with 2 12's. is that on the termlab sensor?????

I agree. Anyone satisfied with what they have will be happy to say how good it is. I don't think either sub is crap personally but everyone has their own opinion.

yes on termlab...measured on db drag competition...with 2 type R's...here is the video of finals....151,1 was in semi final...after that battery was little empty ...but still enough for victory...

everyone is entitled to thier opinion even a misguided one.
you feel 20hz not hear it, if you hear it thats either motor noise , higher freq cone distortions , or many other problems that are speaker and or installer mistakes.
DD subs have plenty of lowend output its just alot cleaner than most due to motor and cone designs.
I personally wouldn't do 8s 10s would outweight on displacement by alot. Lacking space?? buy a larger coiled DD and push more power with some slight EQing on the lowend even if the box is small.
Won't win any SPL contests but will rock that 350Z

AS "KRAVEN" (STEVE) SAID, THE DD1508'S ARE BADASS SUBS.
EVERYONE HAS THEIR OWN OPINION AND EVEN DAVOR IS ENTITLED TO HIS.
THIS IS FACT NOT OPINION:
I HAVE TWO DD1508 IN THE TRUNK OF MY 96 ACCORD. THE AMP RUNNING THEM IS A DDM80 (800 WATTS RATED @ 1 OHM 13.8v). THE SUBS ARE DUAL 4'S. MY CAR ON THE TERMLAB USB SENSOR IS A 141.1dB ON THE WINDSHIELD, AND FOR MECA IS A 141.0dB AT THE HEADREST. THE FREQUENCY IS 38Hz AT THE WINDSHIELD (dBDRAG) AND 36Hz AT THE HEADREST (MECA)
DID I ALSO MENTION THATS WITH A 40AMP FUSE BEFORE THE AMP (FOR MECA RULES)
STEVE (KRAVEN) KNOWS IM NOT BS'n EITHER.
I THINK FOR 2 EIGHTS HITTING OVER A 141 IN A TRUNK CAR WITH ONLY 800 RATED WATTS WITH A 40 AMP PRE-POWER FUSE AT 36-38HZ IS PRETTY NICE. AND IT'S NOT AN SPL BOX EITHER. IT SOUNDS VERRRRYYY NICE. AND IF YOU THINK I DONT KNOW SOUND Q... I HAVE HAD 5 STATE CHAMPIONSHIPS IN SQ AND POSTED THE SECOND HIGHEST SCORE LAST YEAR IN THE MASTER CLASS IN MECA.
I WOULD LOVE TO SEE ANOTHER COMPANY'S 8" SUB TRY TO BEAT IT. I DOUBT IT WILL HAPPEN. I THINK DD HIT A HOMERUN WITH THESE SUBS. KUDOS TO DD!
