I made my own box about 2 years ago that was almost indentical to the one that is being made here. Check it our here
http://www.914world.com/bbs2/index.php?sho...ic=47247&hl I measured the volume with a displacement method and it was perfect for a 8in sub. The 10 needed way too much volume. I bought the JL 8in audio speaker and have way more bass than I need (this fit in my box as I designed it to fit, but may not fit in other check the specs before you buy it). The car interior volume is very small also. It is very clear and has the right sound. If you want to just piss off your neighbors or show off for the ladies go with the 10 but it will not do much as the volume of the box is too small to allow the speaker to move in and out properly. In regards to speaker location, trust me it only works on the left side due to the contour of the body. If you get the JL audio speaker you will need to order the grills on their web site, about 8 dollars if I remember (link to buy the grills) http://store.jlaudio.com/home.php?cat=255. They are strong enough to stand on, really you could stand on top of these things and they will hold it. So get a grill and you should not have a problem with putting your feet thru it. I actually have my floor mats covering the speaker as well. Bass is non-directions unlike trebal and does not need to be in your face or even be seen. The sound waves go in all directions and will reach your ear, even if the speaker in hidden. I love the sound and would totally recommend this set up. |

I went to the JL Audio website and the specs for an 8W3 work with the dimensions Morph posted up above (0.30 ft2 volume and 4.63" mounting depth). I had a pair of 12W3v2's in my last car in a sealed box. Was very impressed with the sound quality and clarity, I'd like to stick with W3's if possible. |

The 8W1v2-4 looks like it's a perfect match for the box, though it's not part of the W3 series that you're looking for:
http://www.crutchfield.com/App/Product/Ite...ofer&tp=111 # 8" 4-ohm subwoofer # metallic-finish polypropylene cone with nitrile-butylene rubber surround # power range: 35-150 watts RMS # peak power handling: 300 watts # frequency response: 28-250 Hz # sensitivity: 83.86 dB # top-mount depth: 3-13/16" # sealed box volume: 0.375 cubic feet |

If I can't get a W3 to work, I'll look at other brands that have an 8" DVC speaker that will. But the more I look at the spec sheet and enclosure requirements on the JL Audio site, the more I'm pretty sure an 8W3 will work. It has the proper mounting depth, volume requirements, etc. The only thing that might not work is if the MDF used isn't thick enough (if the box was designed for a 50watt SVC speaker, there wouldn't be any point in using beefy MDF). That wouldn't be a design problem though, just special order the box with thicker wood. The 8W3v3 only needs 0.30 cubic ft of volume while the 8w1 needs 0.375... weird. The 8w3v3 does need more mounting depth, but still less than the specs Morph posted. Should be good. |

Just out of curiosity, why do you want to stick with dual voice coils? Where do you think the big advantage is there for this application? I'm not saying the W1 is better than the W3, but do the differences in design justify the differences in price and power requirements?
Also, the box is fiberglass, not mdf. |

I don't want to go through the expense and work just to get a little low end fill, might as well go big and get some bass out of it (I tend to get used to things quickly and then go overboard, lol). I'm used to 2 12" W3's, I just don't think I'd be satisfied with an 8" W1. Of course, I had my W3's in the trunk of a mid-sized car, and not right next to my feet, so that's going to make a difference that I should account for. I should probably go somewhere and actually HEAR a W1, but I'm just not that optimistic about them. The other thing about DVC subs is you have more options (bridge amp down to 2 ohms, for instance). As for price, 8W3's really aren't that expensive. I'd happily pay a few bucks more for better sound. The W1's probably sound nice, but I'd rather run my system at 30% of its capability than 80% of its capability. An overbuilt system turned down sounds better than a lower powered system turned up. |

Make a taller and larger dia. ring spacer. Port the encloser to reliever preasure and get movement on coil. QUOTE Ported enclosures actually have more turbulence/pressure in them. They also require a lot more volume than their sealed counterpart. The sub off to the left, and James' original designs are actually very good designs. (acoustically speaking) Thats interesting, I have travel plugs for my Altec 'Voice of the Theater's'. If I forget to take them out of the ports the sound is muffled and reduced until the plugs blow out of the enclosure. You wouldn't happen to have a link to this info would you? |

This is the combo I was thinking of:
JL Audio 8W0 Sub and a JL Audio A1200 amp I can get everything I need to install for under $250.00 Any thoughts? |

The W0's are supposed to be great speakers, and I've personally punished a set of JL Audio's with great results (not W0's though). I think W0's are discontinued, but you should be able to find them left over stock somewhere. Or as RoadGlue mentioned, 8W1's should be a perfect match for that enclosure, and they're a current model so they might be easier to find. Personally, I'm a little eccentric, and want more thump, so I'm gonna find a way to get an 8w3 to work. |

not sure which one I used it was almost 2 years ago. It was around 100 if that helps. It is all black and has JL on the face

i've got a rockford 8" single v/c running off 80 watts and it puts out and good thump not a boom, you don't hear much outside the car but it's very good inside as far as listening to music.
it sounds good with rock,country, but not rap/hiphop bass boomer stuff. |

Is the subwoofer box available? I didn't see it on Ebay or the website. How much is it?

I waited a couple years before buying it because I had trouble imagining it installed. Of course, if I just lifted my carpet it would have come to me.... But think about it.

Paul, You know, I have read so many books on audio systems and have been reading online tutorials from (Kicker, JL Audio, Soundstream, etc) for the past 13 or so years, that I've forgotten where I've got most of the information. I wish I had a link for you, it's some pretty interesting stuff. If I could get L.E.A.P. to work on my computer again w/out having to figure out what is up with my registry this time, I'd be more than happy to send some comparison charts to you. You can PM me about your travel plugs and ports if you'd like, so we can stay on topic here about morph's nifty enclosures. (I hope nifty is on okay descriptor word, I like what has been done with them.) |

The question I have, is do you think it would stand up to a JL Audio 8W3? The volume is right, and the mounting depth is right. I just don't have any experience with 'glass enclosures, and know that MDF will shake apart if you don't use thick enough stuff. If it'll handle the pressure an 8W3 puts off, could I special order one without the speaker at a lower price? |

I have one of these- http://www.bossaudio.com/main/649 (IMG:http://www.bossaudio.com/main/wsc_content/pics/mediabox/medium/11734605391.jpg) Keep in mind these in no way compare in quality to what some are selling, but they do work surprisingly well. I had one under the seat of a 77 Cutlass, and provided enough sound pressure to where I could feel the bass. Cheap also, only about 130 bucks. I was hoping to find room under the dash in my 914 for it. I have heard of a new "flat" sub woofer. Anybody using them? smallest i've seen is a 10". too big from the box morph makes, not enough cubic inches. |
