The Loudest Comps Budget $600

either bostons or avi.

well in older days the diamonds used to break up at high volumes (talking 5 years ago and not so sure on how well the gains were set) i used to sell diamonds let our installer install them then i used to tune (for those that wanted it). used to do the same at another shop that sold boston and never had 1 problem with any type of breaking up. basically all i did was use an iasca disc and make the system center good with how it was installed.i didnt have an rta or any meter but i can honestly say out of the handfuls of cars i did this for most of the time the bostons at least seemed louder. another company that m akes loud and clean drivers is avi. they are canadian made and are pretty hard to find but can take your head off none the less lol. reason i say horns in a situation like this is (being loud) is its a no contest and people who dont carry horns say they sound bad simply due to the fact they dont carry them .

Those morel sets (hexs and pg elites) dont get that loud, dont let the power ratings fool you- they just use up alot of power to get going

Look into the Rainbow Power CMX set...those are designed for a loud/clean fronstage

Well if you want to have fun with an install the DLP7 with a 93dB/w/m efficency will take a 120W sinewave all day long... all week long -- never resting w/o frying your Voice Coil... it is just a tricky install when you have a pair of 7" midbasses on each side //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif 200W by car audio rating standards wouldn't be out of the question if you don't ever put your amp into moderate clipping that is...

If you are adding 8" midbass anyways, and loud is your goal.....I'd just slap a pair of horns under the dash with the 8's and be done with it. Output wise; nothing you mentioned would compare.

Haha....nevermind, I didn't see your last sentence when I wrote that //content.invisioncic.com/y282845/emoticons/blush.gif.99bc659ee2012b7d826165e26fb5eebe.gif

I agree with audiolife then.....Boston or AVI is your best bet if output with "standard" components is your goal. I still say horns would be better though //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

yea that would be interesting... stick some compression drivers in there //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif and figure out a way to assemble a bass horn in your car to get you down to 80-100hz atleast //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- then let some subs take over haha thatd be a trick...

well if you are talking about components i was talking about cd-1e sets image has out they come with a mid. with 75 watts a side they would gooble up anything i can think of in volume. some people love horns some people hate horns but the thing about them is there is no mechanical distortion and much less distortion thats "notacable" at the cross over points. some say they sound like a megaphone but i never had that problem everyone thought i had regular speakers until i told them....even about half the judges that scored my cars lol. anything mentioned up here should do a **** good job though.

A good design + plenty of EQ + horns + great install = nice... 105-113dB/w/m can be managed... more even with some work.... and 50-100 watts of power handling... heh -- tricky though... horns aren't my specialty though //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I'd have to play with them a little more and talk with some people before I can give any real advice... Other than B&C compression drivers sound good //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- and radians are sensitive as heck...

Like audiolife said; Horns will slaughter regular components in output, and match or excel beyond them in sound quality (with proper tuning). 700hz may be pushing it unless you have an extremely steep slope. Full bodied horns should be able to handle 800-850hz @ 24db/oct just fine.

If you want to stick with comps; I had the Pro 6.5 set w/ an Eclipse 34230 running them (400w x 2 @ 4ohm), and they got loud enough that your ears would literally pop, and you could hear them from a few blocks away.....you could be about a block away and hear them from inside a building. Didn't sound as good as my horns at those volumes (horns retain their accuracy better).....but when you're that loud, your ears are distorting just as much if not more than the drivers themselves.

Throat distortion is a pain though... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- get good lenses and its all good though... There are very few horns that sound better in the 100-110dB range (other than the headroom -- which is nice) than conventional speakers though... it is **** near impossible to properly install a horn in a car too...

Active is darn near required for a compression driver setup... take a peak at what is going on with the impedance plot of say.... B&C's top of the line compression driver...

Look at all the various resonant modes... needless to say... the energy storage... isn't too pretty //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif -- that would make one UGLY waterfall plot... and I'm all about the finer details of life... Compression drivers just aren't my cup of tea but there is not much that you can do that is louder thats for sure //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Is the Sensitivity/SPL dB rule true?

Click to expand...

10*log(watts)+sensitivity = volume at ref. distance (typ. one meter) from one speaker.... 2x the speakers and power gain 6dB..... -- half space gain 6dB from a point source..... those are the basic rules that almost work...
