Basically im not a Co Ax expert. I need one with clean highs, low end extension i dont really care abotu and try to keep it around $75 if yo ucan. i THINK i need 6x8's. as efficent as possible. They are for my GF's moms explorer, doing Co Ax's and a little ported 10. i want drop ins so i have as little fabrication as possible.

Remember this. The higher the tone at a given ammount of movement the faster the cone has to move. Also remember that when you are accelerating an object form 0-300m/s in a matter of say 5" there is a LOT of force on it. assumeing that you are trying to get loud from sonic booms and not actually the tone it would also be usefull to make the "cone" as arodynamic as possible. and inverted dusctap that covers the entrie cone would be optimal. remember what a sonic boom is too. its where the soundwaves get build up and built up untill the object is actually moving faster than the sound itsself and then the pressure from the built up waves is all released at once. wether a sonic boom would happen in a piston type confiuration i have no idea. Here is an example. im not sure how to figure out cone velocity but if i am doing this correctly at 80Hz you would have to have 158.4" of total linear stroke. a 250g mms would need around 6500 N of average force w/o taking into account pressure buildup on the cone. it would also have over 2600 times the force of gravity on it. this is assumeing i calculated cone velocity correctly

Brad nails are teh shizzle.

RE 8's bottom out because they are efficent and LOUD little bastards. If they had a bottomless design they would be 11,000 times better, they new ones may, i dont know.

TB 8's, i know they where in the Great 8 challenged but i dont feel like looking it up on SIN (CSO) so how do they compare as a drop in for the OLD RE8's? i may be in for 4 also, how would 2 of them sound in a wicked one with 100w for HT

You should have stuck him on the windsheild and put colod lights on the outside and lt him bob back and forth made it look like he was on a lighted dance floor, lmao.

Oh, and this proves to me that there are better ways to acheive what LMT acheives w/o 80db 1w/1m.

Yes. Any you can't strap JL amps foo... I had Two MTX 1501d's strapped on it...and 2ohms each...and that was where it needed to be. NG <{POST_SNAPBACK}> Hmm, oh and you can link JL's togather , not actually strapping but yeah. I didnt realize it was this inefficent. Which is kinda funny that it is a HT driver because the ammount of money you would have to spend on an amp for it to reach its full potential wattage wise would be massive. 2kW HT amps arent cheap. oh well, thought i would get to play with the beast. Any other suggestions. once agian w713 performance, 500ish dollars or so and power is either one or two JL 500's. This kid likes nothing but JL amps and he has the money for them so more power to him.

it's reallt THAT inefficent? 500w is nothing to sneaze at (though i know you all ready know this) What about two 500/1's strapped? 900w is in the recocomended RMS

Ok, Got the 4 RE8's in my friends truck, he likes them, a lil port noise, but he likes them. but he wants something that drops lower. i plainly asked him when i was deigning this one if he wanted it to drop low... he said he doesnt care about low notes...he just wants loud. hence the 36Hz tuning. now he wants low and louder...and hes had it a whole 4 days with the gians set correctly. He is thinking about a JL w7 13 sine he wants something that will sound good, get loud, and drop low off of the 500/1 he has. i immediatly though of a list of driver fitting the bill without going cookie cutter w713. in come RL-s 12. My question is, what kind of enclosre for car and what kind of #'s can i expect in an extended cab GMC 1500. we are going to get him metered sometime soon so that will give you a reference point.

You can halfway maybe count me in on one. if that is still possible. when is payment needed (i didnt feel like reading the WHOLE thread)

its going on the 2 SE's eh? should be nice

My dad goes about once a year and w/e mileage it gets to it gets to.

and now that i think of it, the $100+ i was going to use to get Nick's Entasi can now go to TB's....Maybe even my GF's B-Day present. she is getting a new car soon. 4 6's should be enough for her and she'll keep her trunk space.

Yes, how cheap are we talking? depending, i could go for as many as 6-8 myself. 8 TB 6's + Wicked One = Funer than AW 10's

my Ava 18 i didnt get to attend ANY shows in 2005.

Price mistake...for that price...wow...i should have picked some up. they still probably didnt loose any money though...probably just about broke even.

ya, older modles arent as good but they still wang. from what ive read its just a new back plate and a new spider. i was planing on forward firing ports but the elbows are jsut too damn big with 3" and im already pushing it with port area and my tuning. WinISD says im pushing 80ft/sec around tuning with 500w. i only have around 14sqin of port area...when i should have more like 22 (12 for ever 1 rule of thumb, though that is for slot ports, its a good idea for around 10 for every one with high excurstion drivers excluding ports that are extrmely flared like areoports) anyway. Id i feel like im loosing loudness or an getting cancelation from the ports im going to tear htem out (fun, they are epoxied in), glass the hole shut, and use 21/2 forward firing only im going to have to sand the elbows paper thin and reenforce them a little on the inside to get the speakers to drop in. oh well. should still be louder than sealed, though if we had gone sealed we could have done 8 and 1200w in the room we had. should still wang hard

here it is, ready to go minus cosmetics. gonan finsih bondoing tonight maybe and then sanding Monday night, paint tuesday and installed wednesday. i cant wait to hear this. its been my baby for the past 3 weeks or so...20 min here or there.

Kool Kool... Here is the box (you saw a pic of the beginings before i think) still nto finsihed. just got the PVC for the ports and Bondo to finish it off today. as soon as i finish this post im going to put hte ports in and screw the baffle on. And here is a comparison to a cheapo 8... i dont even reemmber what brand, it came out of a bass tube, the bass tube and al lwas like $60. of ocurse the amp was pure garbage. anyway...i tas silver, i painted it black and put a ghetto brahma dust cap on it. and here is the wickedest scrap box you'll evah see evah...prototype for what a more SPL friendly version will be w/ 2 187 12's or other entry SPL driver. basically i figure if i can get this to get over 140 on the AC with my 2 Audiobahn 10's im trying to sell its worth it modified for SPL as i am doing the enclsoure text book....so its really designed for like extention down to 20Hz flat to like 5,000Hz if you flip the baffle....but ya

Sweet...i like the new one better...just because its faster. lmao what's with red and BMW's? When i see red and i think car its either Older M5 or any ferrari.

just changed the oil today, hadnt been changed in over 7 months and 8,000 miles. Was black as night. I went ahead and spring for Mobil 1 Full Synthetic. Its amazing what good, freash fluids can do too. Truck is running even smoother and feel like it has a few more ponies. Maybe im actually sitting at around 150bhp now...lol. The list of 2 do's: Coolant Transmission Fluid Differential Fluid Vacume Tubes Spark Plugs Wires Coil Pack Next Perfomance upgrade will either be a custom intake of TB spacer.

BTW, do yo ucompeate DB drag or onla IASCA events? i may make it to spring break nationals. I want to attend the 1x 2x event in The Orlando/Gainsville/Ocala area but my parents have me preoccupied then too. DAMN IT!

I wanna come, and i want to bring my GF too...but god dammnit my paretns are dragging me to GA to freez my arse off. My new years resolution: Attends a freaking IASCA meet kickin' is at so i can finally heat 150+ on the AC Well anyway...hopefully ill be hearing another 145+ on the AC soon. iddy biddy eh? 2 more installs and im ordering a pair of 187 12's . i might save up more and get a pair of LI 10's or 12's...or i might end up blwoing it on Amanda...w/e...damn chicks steal your money and you dont even know it.

my room is ungodly dirty
