It depends on the version he has. It's a 2008 model...

My choice fell on a RE XXX-18... The RL-p 18's wasn't in stock at that time, and I had a chance to try something new at a reasonable price.

Just to point it out, (I think at least one of the above posters have it wrong) lowering the tuning frequency of the enclosure, will actually decrease the subwoofers excursion @ the same SPL levels compared to the sealed enclosure, making it take more power at those low frequencies (impedance will rise also, right). Since we need 4 times the excursion to maintain the same SPL level at 20hz compared to 40hz (in a sealed/IB install), I don't see how tuning low isn't a good thing, it will not make the driver "unload" any easier, but it'll lower the treshold for where it will do so. Which is good, right? If one is seeking a flat response from a capable driver, and stay linear while hitting high SPL numbers across the frequency band (sealed boxes don't do lows any good compared to a 20hz tuned ported enclosure), tuning low is a must in my opinion. Yes, it is unpractical with low tuning due to the long port(s) and big enclosure, and with some speakers it's just not a good idea due to their lack of low frequency capabilities in general, but: I've heard low tuned enclosures (with subwoofers that thrives in such boxes, like the SoundSplinter RL-p or JL W7's), allthough they're recommended for sealed also, honestly, the SQ is not lacking in any way, when putting them in a very low tuned enclosure. It just kills the sealed when it comes to output. In my opinion, a 10W7 in a 4 cu.ft. @ 22hz enclosure, sounds BETTER (the low notes sound more effortless) and has the capability of getting much louder, than a 10W7 in 1.5 cu.ft. sealed. 3dB more @ 40hz, and 6dB more @ 30hz, 10dB more @ 20hz - that says a lot. With enough power, I do think you'll bottom the sub out in the sealed enclosure @ 25hz, while the one in the ported enclosure laughs at the same SPL. Not saying ported is always better, it obviously depends on the sub, but if the sub thrives in a ported box, and I have the room for a <30hz tuned enclosure, that's what I'll build.

I really wanted to post a picture of my new girlfriend with my new XXX-18 on her lap (she almost disappears behind it), but I think I'll restrain myself from posting it. But I don't mind posting this, though, a picture from when I swapped my (for me) one week old RE XXX-12 into (2) JL 10W7's.

I have a $2000 car with $6000 worth of equipment in it - and the ratio keep getting worse I realize I have had over 15 different cars in 5 years, because I get bored when the car audio install is done, and I need to start over in a new car I have dreamt of car audio on several occasions I get angry when my friends buy shitty equipment because they don't "prioritize" having a good car audio system I can remember at least three girls I've had sex with, while I was thinking of car audio sitting in a car with a crappy sound system, just makes me want someone dead I must really restrain myself from buying good equipment to people (and paying for it myself) just because I can't stand the sound from a crappy system someone asks for my help with a $300 system, and I refuse because it's not worth the trouble with that small budget.

What is da plan for the XXX 18? i say big box+low tune (25-28hz). But thats just me. Hi! Yes, exactly, it's around 14cu.ft @ 25hz, "walled" in my '74 Mini.

No hard feelings.

With my 7 years of car audio experience (that's experience, not jerking off at a web forum), and the social intelligence above that of an average rat, I'd say you're the one doing the insulting here. It works very well. That shelf is "dead" as a fresh piece of roadkill. Think about it... 15 pounds of wood, enforced by U-shaped steel bars, with the added mass of the two 10W7's. And it's jammed tight between the rear seats and the door, when it's shut. It's not vibrating, even when playing really loud.

Its not point in him telling you what you can see, that is just a shelf for the w7's with the back door as the rest of the enclosure. Correct. There's also a wall of 19mm MDF against the back of the back seats, to seal off the cargo space from the rest of the car. The cargo space is really square, and easy to seal off, so there's no leaks into the car. While this may be considered a "free air" installation (with a 6" port, though), I don't see how an enclosure the same size (270 litres) would make it sound or function any better than it does. The "shelf" is also cut to fit and seal when the door is shut, and the "shelf" itself is 22mm particle board reinforced with two U-shaped steel bars from side to side. It makes a very efficient, light weight "enclosure". And they get "loud enough" (guessing high 130's) with just 150w each (when I get time, I'll change the amp to the RSd1200.1, and get it metered just for fun).

... See previous post.

Also found some images from when doing the PT install the first time.

Found some pics of the Mini on my Photobucket account...

And why use both the XXX-18 and the Morels, you ask? Well. Beacuse I can, and I want high sensitivity all the way down... Because XXX-18 in 14 cubes @ 25 hz is a killer SUB BASS (this enclosure yields 93,5dB sensitivity @ 30hz). Morel Elate SW10's have ~50 grams of MMS and reach full (+/- 5mm) full excursion with less than 50 watts if playing less than 50hz... Also, pictures say more than words, so here you go:

Oops, sorry, I don't think I made myself clear... Obviously. The JL 10W7's in the 9 cubes @ 20hz, are in ANOTHER car (a 2000 PT Cruiser, which I use daily). Observe the sweet, pink speaker wire. And yes, I know the carpet for the home-made cargo shelf don't match, I just haven't found the correct color anywhere... I have two new Phoenix Gold RSd-amps (300.4 and 1200.1) laying here, I just have to install them when I have time... Notice the nice frequency response in WinISD. Sounds just as nice too! In my "project car" (the 1974 Mini), I'll put my RE XXX-18 (->50hz), three Morel Elate SW10's for 50-100hz, and Morel Integra Ovation XO 6 speakers. I'll power the XXX-18 with a Helix Dark Blue 1000.2 amp, and the rest of the speakers (SW10's and Ovation XO 6) with a Harman/Kardon CA5250 amp (the sub-channel pulls all three Elate SW10's easily @ 1,33 ohms, I know this as this was my previous setup in the PT Cruiser). This amp is 2 x 150W RMS @ 4 ohms bridged + 300W RMS @ 2 ohms on the sub channel. It actually kicks major ass for being so cheap! (The sub channel is actually currently running the two 10W7's in my PT right now @ 1,5 ohms, and it sounds really good, and gets "loud enough" for daily usage). Don't have any pictures of the mini project so far... But this is the XXX-18, my XXX-12 (which I swapped for my brother's two 10W7's), and one of the Morel Elate SW10's.

Thanks for the input, guys. Got a nice deal on a RE XXX-18 today.
