Something different...

Been looking at my truck and considering install options, and components, and all that good stuff.

Any sub, including the 8W3v2 I got, is going to be extremely difficult to squeeze anywhere in this truck. I can go get buckets, but I came up with another (unique) option.

Either a single or dual SEAS Excel W15CH or W18E midbass drivers combined with the Millenium tweeter or LCY Ribbons. Ported front stage

that should give extension down to 40s or possibly even 30s, especially with cabin gain factored in. MTM D'Appolito configuration if dual midbasses. No sub, primarily a system for SQ material.

What do you think, especially Geolemon since you've had experience with a line array in your truck? This is one I haven't done before, and I'm up for a little fun :) Wasn't that a single cab truck you were using the array in? Just curious what you ran into.

with a little shaped fiberglass work you could fit a small sub behind the center console or up behind the dash ala-HLCD style.

"with a little shaped fiberglass work you could fit a small sub behind the center console or up behind the dash ala-HLCD style."

Very true, and I'm running over those options. Regardless of that (I know I can get the sub in there some kind of way), I'm considering this whether I do the sub or not

Remember I've still got the ID Max and Dyns for my future truck, this truck was a freebie that I bum around in for gas mileage sake, so I won't feel guilty if I gut it. If it doesn't work out, the Excels can go in my house. Gives me something to do anyway, I think I'm going to go for this. It's kind of like how you use your Oddyseys for imaging and as a SQ reference, then have the Kef References as home theater

what about putting an AP enclosure in the door

"what about putting an AP enclosure in the door"

Could help SQ wise, but it isn't going to aid low end extension or efficiency at that point, especially not compared to ported. I am curious what it would sound like, though. With AP on something like the Excels, you'd be more limited by the excursion capabilities of the driver. I'd say the newer Nextel paper coned versions could go pretty low, the motor design is flat out incredible. I'd have to say the most refined motor I've ever seen on a Klippel analysis, flatter and more symmetrical BL curve than the Scanspeaks, Adire Extremis, pretty much everything I've seen in midwoofer entries.

how big of a ported enclosure can you get for the Seas? i know my bravox will play into the 40hz area open room with a .5 cube box and in the car with a 1 cube box i could play into the 30hz area with only a 5 1/4. so if you have the room you should be able to do it.

And what is this going in again? My single cab s-10 I had the four 8's behind my seat. Can't you just move the seat a little bit forward? :)

"And what is this going in again? My single cab s-10 I had the four 8's behind my seat. Can't you just move the seat a little bit forward?"

S-10s have more room behind the seat. Remember this is an 86 Ranger, they didn't up the size of the regular cab until the 98 year. Moving the seat really far forward is a no-no, because

1: I'm tall
2: I don't want to screw up the soundstage of the truck for subbass. I'd rather lose one octave than screw up the other 9 to get it.

I've already bought the sub, and I'm going to do everything I can to get it in here comfortably. It'll go somewhere.

Right now I'm figuring up a kickass soundstage :) I think it'll be cool and something different if I can get a 5.25 or 7" mid playing 30hz than a sub, just for the eye opening factor

. I could still have the sub to compliment the stage when I wanted (or needed) it. Just the mag cone Excel with the older motor can go to 30hz flat in a car door, no telling what the newer ones can do saying they have a lot more linear excursion. So yeah, it's doable, no question there. I would rather have the ported box to limit excursion down low, if it were too much I could EQ it down and lessen strain on the driver down low. Using the sub, I'd still get sick midbass output from ported front mids, along with them being notably cleaner at higher volumes.

"how big of a ported enclosure can you get for the Seas? i know my bravox will play into the 40hz area open room with a .5 cube box and in the car with a 1 cube box i could play into the 30hz area with only a 5 1/4. so if you have the room you should be able to do it."

I've run over a few options. With the W18E001 (7") mag cone Excels, I can do a .68 cu ft net enclosure tuned to 36hz, the W18EX001 (stronger motor, lower Qts) can do a .26 net tuned to 50hz, both being QB3 alignments. Out of the 5" mids, the W15CH can do a .6 cu ft net tuned to 36hz, and the W15CY can do .24 cu ft net tuned to 43hz, both of those also being QB3. The W15CH is the best midrange performer and has the better motor design out of the mag coned excels. I haven't plotted the Nextel paper coned drivers, but I've seen Klippel analysis and they have the most linear motors (they're the newest design). They'd also be easier to work with as far as the crossover design, as it wouldn't require a notch filter. Bad part is Fs is higher, tuning low isn't a big option with either of them. Anyway, they make a lot of drivers and I'd have a lot of options. Most of their home setups can go into the 30s in room, not counting what they'll do in a car.

Maybe I should become a car manufacturer, and for the factory system I could design the doors to be one huge TL enclosure

i like keith turner's approach to his truck install.

as you know i back the concept of gutting behind the dash. decided it was too much work for me considering i have so much room in the center console. but i like the idea of a lack of a true sub altogether and accomplishing the same lows. the whole "where's your sub" effect would be cool whichever way you went.

It's also because I'd like to try an MTM configuration in a car. Properly implemented, it would allow you to control the dispersion (to a degree) and potentially aid your imaging by possibly cutting down on the reflections you experience from the windshield, dash, so on and so forth. Maybe a more focused image, maybe crappy imaging, who knows? May as well try, though.
