ebay claims they are spl subs, their website claims they are quality based subs. Oh and did u read- Lifetime Warranty

Anybody ever hear of this company? All they make is extremely high priced speakers and a single 10, 12 and 15. They claim to build very high efficient spl subs but the cost is ridiculous. For instance, they have a 10" sub that only uses a 2" coil, rated at 400wrms but goes for $1,000 new, $800 on ebay or $500 if you are sponsored. Here is their site- www.acshockwave.com

gain is NOT a volume control. Secondly, if it's the PDX amp, u ned to be VERY careful. If it's the MRD amp, then you will be fine. I got a buddy that used to run 2 of them off a 2,000w amp properly tuned and they never got hot, we just had to monitor the movement as the box used was ported and built to maximum recommendation which was actually too much for the power we had so the subsonic filter had to be cranked way up to prevent bottoming out. You may not have that problem as long as the sealed box isn't too large.

well, gotta start tunin the new wall i built a few weeks ago since my close competitor just pulled a 154.0 flat and i have yet to consistently break a 153 so it's time to up my game. I already got enough power.. can't use any more with my fusing so it's tuning and car modding time. I just got done doin a low volume pressure test with the passenger side door panel on, then off... I gained 0.1 db with the panel off as i've heard door panels absorb pressure so i might need to leave it off for competition. I am going to be SPL tiling the hell out of my passenger door soon. Here is the door before- I'll have a pic of it once it's deadened. I see several holes out the side of this door which are there for no apparent reasoning... They will be sealed! the holes on the bottom of the door must be left there to properly drain water from when it rains. I will be attempting to seal the door speaker in place too as this will also add bracing to the door. I tried to do a pressure test before and after removing the port plug.. but, hehe while trying the meter stand wouldnt sit still so i was getting inaccurate readings. The score did drop ~1.5db which may be expected because the tuning is "loose" right now but i need to bring this wall up to WAY over a 153.. hopefully over a 154 within the next 10 days. I'm gonna be busy.

The shows turned out pretty good, especially fools fest today. Me and phi placed 1st Saturday and 2nd Today, coincidentally. I just seen somethin kinda scary as soon as i got home, so luckily both me and Phi made it home safe, .... Just In Time! I just walked in the door and news crews are out on the same part of the interstate we just got done traveling on where a hummer slammed into a semi and caused a fatality instantly. the hummer is completely destroyed and the interstate is backed up for SEVERAL miles... Scary... Also, on the way down to the show, i thought i was seein things until i seen 2 shredded tires on the side of the road... next to the ROTOR that fell off of some semi. It was a pretty massive sized rotor too. Seems like we just got lucky makin it down there and back.

unless i missed that part.. i just heard it was supposedly caused by friction which is too broad of an answer. They keep referring to the pedal getting stuck, not what controls it.. i'm complaining about what i hear.

it doesnt matter if u have 1 sub, lol. If you guys were keepin up with the A team, they just posted a 177 with a single 15 and less than 13,000w of actual power. On their power chart, they also produced a 154.x with less than 40w clamped. It is an extremely modded vehicle to be able to do that, i bet many of you can't do those numbers inside the box itself! Anyways, different parts of the body have their own resonance. If you wanna be a db assassin about it... resonance is what i'd be researching on different parts of the body and try to produce pressure on those notes.

Forgot to post this up but there are 2 shows this weekend. first is at 450 butler drive Murfreesboro, TN @10am CST on 3-27-2010 second is at 1318 West Main Street Lebanon, TN @10am CST on 3-28-2010 I will be at both shows. If u wanna come out to play, the cost is only $25 to compete($20 for MECA members).

regardless of driver comparison- If you are looking for steady daily driving, more cone area is better for dispersing the heat IF and ONLY IF you are running a lot of power. If you are matching a sub with the proper amp, a single sub would be the better choice. I prefer single sub setups over dual or even triple setups when done correctly.

that's why i like toyota. They are reliable. The gas recall thing... if it really is even an issue.... is bullshit. If it's a real issue, fix it yourself... there's no way some bad parts of magical problems has floated onto hundreds of vehicles just waiting to get stuck while cruising. You can thank the media for blowing it way out of proportion like they always do... and the people... how gullible they are, will fall for the crap and believe anything they say. isn't is interesting how they don't really say why it happens? Sure they say friction.. that's crap. they gotta make up somethin to please the retards who believe everything the news says... all they are are middlemen relaying hearsay... The probable truth is there is no one problem and to ask Toyota what THE problem is.. they gotta make up somethin or else they would look stupid. Ever since the gas pedal story started... it's like a news story boner for the next month to many. [/rant]

they are making them for all kinds of vehicles.l it just takes time

not necessary. I've actually tested stock fans on ~30% OC'ed systems. If you do lots of transcoding video, the processor WILL overheat. If you are doing things not related to video transcoding (authoring video discs, video editing, etc... is still a form of this)... then a stock fan can actually keep it pretty cool! To test the temp of the cores for video editing, you need an FPU benchmark done... but i can tell u now, no stock fan will keep even the slightest oc'ed pc cool on an fpu test. Prime95 will test the hell out of it but honestly, prime95 overstresses the cpu compared to what people can possibly do to them.

how much power and what was the box tuned too prior to downfiring? Downfiring will probably lower tuning slightly but if the port is left too close to the floor with massive power output, it can cause turbulence and if on a meter, cause your peak to drop because turbulence drops with frequency. It's possible 4" may be too close but you should see what kind of power he was using first.

lol.no i can assure u that a porn tab would have its own browser window. :)that tab and the lower left program window are things i wont publicly exposeits related to hobbies i work in and i dont want unfinished work or research showneven the software used... too much competition out there

just created account and this is what it does when i add stuff to the cart-

lol, you'd be ok on stock alt and 300,000w. It all depends on how well you monitor what's goin on with your electrical system. Take me for example- My alt can only output so much current so when it maxes out, the rest comes from the batteries. Now, i never listen to it loud for no more than a few seconds because it's unbearable. But let's say i did anyways. Once the constant load is gone, the alt is still maxed out to charge the batteries back up... that's NOT what you want. If that happens, the alt can overheat and die eventually. IF that were to ever happen(from monitoring your system properly), you can unhook the charging cable that separates your starting battery from the entire rear battery bank. that way, the alternator only charges the starting battery and to prevent an alt failure to charge the rest in the back, they would be manually charged via charger and left unhooked from the car until they are fully charged back up.

stock alt (110A) 21,000w of amplifier power. been that way for about 3 months, no problems whatsoever. Might have to put the battery charger on a batt bank once every 10-15days but besides that, they stay at 13.2v rest. I'm patiently waiting for a secret alternator...i'm in no rush.

need to check the store site, man. It's tellin me that i cannot create an account because it can't ship to louisville, ky.

since the enclosure is basically dual chambered, you would divide the port width in half = 4.75" and that's the minimum space to be used between the back wall and end of port wall. If you make the space that size, your port length will increase by several inches decreasing port tuning. If you make the space larger, it will slightly increase tuning compared to lengthening it as said above.

honestly, cone area is becoming irrelevant lately... Been competing.. i've seen plenty of designs where cone area isn't the key. If you disregard installation and design, motor force and power is what's left. Even for those who don't compete, pressure is pressure. It's how much of a difference can be heard? Typically, a 3db change can be heard. I strongly believe a 15" btl in the proper daily tuned box will perform greatly over 3 8s. I have nothing against the sa's, i would just go the btl route. When running multiple subs, you start getting into phasing and while 99% of people don't fool around with this area.. you'd be surprised how multi sub setups can get complicated. I look into the nitty gritty side of things from a competitive side. I just believe there's more potential there with a 15. Now, that depends on how far the user wants to go to get it installed in an efficient design.

the 15 more than likely has more motor.. i'd go 15.

i tested at 152.2 then i taped around all subs and all 90degree corners and did a 153.4 biches,heheim still not tuned... but i got the official headrest stand now

u may have seen it in person... but not wired up Here it is wired up-

this is what happens when your amps don't have line outs and u gotta do everything the old fashion way... Now, this is what happens when i install them- The final pic will come soon... just gotta go take it.

no, each port will still need to be a little bit longer even when maintaining the same port area as one large port.
