Hi all,
What would the best enclosure be for dual 10" Type R's?
Ported or sealed?
I understand that Ported gives you great low bass and Sealed has great tight kicking bass. Is this correct.
I listen to music like Skrillex and Metallica, But also RnB, Rap when the girlfriend is riding with me(Cant handle heavy anything/screaming haha).

This is in my 2009 Ford Falcon XR6 4 door sedan, Lots of internal volume/large vehicle.
Thanks for any advice!!!

What do YOU want to do? For your tastes, a vented enclosure, tuned to about 35 to 40Hz will probably do you just fine...
Me...? I don't like vented enclosures, especially tuned that high. I sacrifice space for extension any day, and tune for drastically lower than that, or just go sealed, which is a completely different response curve.
Everybody you ask will likely give you a different opinion. :P
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I have limited space and I like tight bass so I suppose My choice had already been made for me eh? Will start getting it built this weekend hopefully.

So after weeks of checking everything out I went ahead and followed Alpines Recommendation of .6Cu ft Sealed for a Alpine SWR-1043D. I have two of these, both in .6Cu ft enclosures and they lack definition, I have since spoken to an Alpine certified installer and he recommends a 1.0Cu Ft enclosure for each sub.   So back to the drawing board it was.
Mounting Depth: 149mm (5.875")
Mounting Diameter - Front Mount: 231mm (9.1")
Displacement - Front Mount: 0.080 Cu ft
Added Volume - Reverse Mount (magnet out): 0.055 Cu ft
Recommended Enclosure Alignments: Sealed, Vented, Bandpass
Sealed Box Volume Range (Gross): 0.5-1.0 Cu ft
Optimum Sealed Box:
    External Box Dimensions 12.5" x 12.5" x 10"
    Gross Internal Volume: 0.60 Cu ft
    Net Internal Volume: 0.50 Cu ft
    Cu F, Qtc: 46Hz, 0.90
I have come up with this, As close to 1.0Cu as I could get with the sub volume taken out(2.1733Cu Ft /2 - 0.08Cu displacement = 1.00665Cu ft/sub)
Sorry for the drawing, it's my first so let me know if something needs amending. :-S

Anybody able to provide me with Dimensions similar to above for these subs in a ported MDF enclosure?
I don't think I'm up to that stage of enthusiast audio yet :-S
Alpine Optimum Vented Box:
    External Box Dimensions: 12.5" x 12.5" x 20.5"
    Gross Internal Volume: 1.4 ft³
    Vent Area (dimensions): 11 in² (11" x 1")
    Vent Length: 18.5"
    Vent Displacement: 0.24 ft³
    Net Internal Volume (Vb): 1.1 ft³
    F³, ripple, Fb: 28Hz, 4.5dB, 35Hz
    Nominal Impedance: 4ohmd+4ohms
    Frequency Response: 26-200Hz
    Sensitivity (SPL @ 1W/1m): 83dB
    D.C Coil Resistance (Re): 3.7ohms +3.7ohms
    Inductance (Le) 1kHz/20kHz: 3.79mH/1.93mH
    Free Air Resonance (Fs): 31Hz
    Equivalent Stiffness (Vas): 21L (0.75 ft³)
    Mechanical Q (Qms): 7.9
    Electrical Q (Qes): 0.57
    Total Q (Qts): 0.53
    Xmax10 (One-Way Xmax @ 10% Distortion): 20mm
    Mechanical Excursion, Peak-to-Peak: 70mm
    Gap Height (Hag): 10mm
    Coil Height (Hvc): 44mm
    Cone Area (Sd): 332 cm²
    Voice Coil Diameter: 65mm (2.6")
    Magnet Weight: 128oz
If you have a preferred size(Cu Ft)over Alpines recommendation enclosure please let me know.
I would like to use 3/4" MDF as I can get as much as I need for free :-)
I cannot exceed 11" High and 31" Long due to the boot space :-( however I understand there will not be enough room so I would be happy to allow the enclosure to hang over the spare tire well if needed.
I listen to a lot of rap, hip hop, and electronic/techno music (Skrillex) bit of the good old rock here and there. Really want to feel the music in my chest :-D
Thanks to anyone who can help out, I greatly appreciate it :-)
