For SPL-clamshelling or iso isn't going to help, just raise the level of power needed to acchieve a certain SPL.

The only benefit for iso is decreaseing vas bay half and increaseing power handling before distortion.

with 12 15s though, if you have the power clamshell away...

What the  :o is this?
My very first post on this forum, I asked the same question and you told me not to bother. Have you become totally light headed today or have I finally worn down your resolve. Smiley

Lets hope 60's resolve is okay, he saves many of us form horrible experiments by saying:

"Build it exactly as the plans show and load it with suggested drivers and it should sound great?"

*I like how he always puts the question mark, like don't you agree*

Maybe I should say "Who the Hell is this and what has he done with 60?"

So true! I pound that drum frequently, but not like the Maestro.

lol, you guys Embarrassed
i dont know what it is, my experiences so far with building steves desighns are that they work, very well, all of them.i wanted good quality bass and loud, and i got it.but dirt reading some of your VAST experience leads me to believe you are in a leauge of your own. how many people have had the oppertunity to play with the rigs you have and over the period of time?..not many i bet. im sure when you move from 2 watts in a room to 20,000 in an arena things must change? everybodys enthusiam  for the 'excess' when it comes to bass, has obviously rubbed off on me- "thanks" Roll Eyes. im 42 next year and i have built 6 subwoofers this year and an i.b install in my car Cry  if you guys dont stop talking about insane bass rigs that make your neibour wanna vomit when it hits low and makes yer beer froth over as you walk by the sub, im going to be unable to resist building more next year, and im really not sure my wife can take it? i dont post as often nowdays cos both my in door and in car systems satisfy for now? but i frequently read all your posts and laugh and drool and wonder ??? thanks to all of you bassheads for not leaving me out there....here, on my own..................... Cheesy  i wonder what 10,000 real watts on a pair of some of these modern subs (3,4,5000wrms capable) in a modded wo would feel like? or a hw Cheesy  i would love to have a sub make me vomit @20 hz, seriously i might not wanna do it twice but id love to feel that much pressure that low Grin

Your original statement still stands as good advice 60.
I have taken on the same stand, on your first build anyway!
DD has loads more experience than I and I am sure keeps up on his stuff. I mean what else has he to do during the day Smiley ( thats a joke)
After I screwed up steves subs I took your advice 60 and life improved to the point where I started modding after I knew what it was supposed to do.
DD keeps my head on my shoulders and helped me from making some time consuming mistakes that would have frustrated the heck out of me.

both you guys are from differant worlds but none the less, your rocks in mine.

oh ya
Since when is your present car system based on steves design 60....... thats all you!

I have an I.B. in my wagon and it sounds awsome but it just does not get loud enough for the times a guy likes it loud.

Any other sub takes up way too much room to equal it in SQ and low extention and  that includes Decwares.

It is built into the rear well of the station wagon. after my alpines were stolen I did not want my system out for people to see.
I recessed an ADS sub plate and covered it with material to stealth it. you would never know it was there. all my other crossovers and amps were recessed into the same well as well.

anyway I am screwing up this thread so later!
