Single 12 hitting 142 Decibels?

Did it happen? I have no idea.

Could it have? Absolutely.

Like others have said. SPL experts have no interest in music.

They choose the best frequency for the car, the best sub for that frequency and the best enclosure to play it loud.

Even a cheap sub can play extremely loud if it's set up right.

The one that always shocked me was a few years back -- I believe the guy's name was Nate Munson -- Took a 10" DD9510 and did just shy of 170dB w/5kw. I guess the old mic's read high, but it was easily 165db by today's mic.

possibly yeah. It all depends on what type of car it was in, the smaller the better. Also the type of box that was used. The box could be tuned to around 50 - 60 hz. It wouldn't sound very good, its only for getting loud for high scores. The amount of power is also a factor. With the correct box subs can take way more power than recommended but only around the tuning frequency and only for a short time before the coils burn out.

So to answer yes its possible, but only for a short time, and it couldnt be used every day for music

I see that FSMetc is employing the old saxon spelling of disciples. What decibels Sir. have been given it in a single Obi old son. i ask your self why Sir he did that Sir. To confuse people Obi me old mate. So how many decibels have been there Sir ? 15. You specific Sir. I recommend i'm able to in hassle-free terms count quantity 12. Fred,Harry and Inigo. Sir ! The lacking 3 disciples. You recommend decibels Sir. don't get clever arsed with me or it fairly is P45 time. pay attention you loud and clean Sir. specific Fred the Shepherd, Harry the Goatherd and Inigo the Artist. What befell to them Sir ? All have been given fired by using JC. Why so Sir ? did no longer attend the final supper.

I have a single dual 2ohm (in parallel) T2-12 fed with a T1500-1bd, slot ported, tuned to 30hz in a Mustang, coupled with my highs producing 141db. It's clean, so I suspect it wouldn't be difficult to achieve. I also have a T2-12 co-operating with 2 10w7's in an F250 hitting +151db. Granted the 10w7's are work horses, and providing most of the share.

It all depends on what kind of vehicle it was in and how hard he was pushing that sub.

hell yea thats possible. its all about the install and the vehicle involved.
