Does anyone know if this driver can be mounted in a downfiring position?
According to Adire's equation, the AV12 has a 2.43% sag, and so should work well firing down.
I ran all of the T/S Params in WinISD and it has less than 3% G-Loss the 2.43% factor is right on, yes it can be mounted down firing.
Thank's guys that was fast! Now I have to figure which sealed enclosure size needed for a mid Q design. Thank's again for your help. Andy
The low Vas allows a pretty small Q=.7 box if that's what you're after, but if I was going as large as 3 ft^3 I'd definitely go with two 15" passive radiators.
I'm looking for a sub that is good on music as well as movies. The big issue is it needs to be toddler proof. I think the passive radiators would be to tempting.
The output sealed is of course going to be lower than what
your going to get ported or running a pair of PR's but
honestly in a 2ft sealed enclosure it's not going to be
a slouch at all.
But if your a crazy bass head like some of these guys
then ported or PR'd is the way to fly (or rattle I should
say... everything off the walls..)
This one's much too rolled-off to work for me in my room sealed without EQ/LT, but it does have the Vd for decent headroom down low in a tiny box.
I could go as high as 2 cu/ft for the enclosure. This would lower the Q which I assume is better for music but not for HT right? Thanks for all your help.
Should work well for both with moderate room gain and corner placement.
What's the current price on the AV-12? US$140 or US$175? If you click on "add to cart" it notes the price as US$140....however if you read the text above, it says that the price is US$175 AFTER October 21, 2002.
I presume that all new orders are all dual 2 ohm subs....which is what I need if I use it for a car application.
David, John hasn't said one way or the other and he's been busy with CES and all.. I ordered mine way after the pre order and I got it for $140.00 The way I look at it is that John is a very decent man and he will honor that price since when you order it, it sends you an order confirmation email which has the $140.00 price listed. Untill he updates the web site and the order form I say he must be helping everyone out because of the delays they had to wait through perhaps.. At any rate even at a buck seventy five they are still one hell of a sub for the price (or even twice the price)
Just ordered one.
David, Cool, Hope ya get it at the Pre Order price.. Like I said though even at his "retail" price it's cheap for what ya get!
Great purchase, mine should be here in a few days.
FWIW, I'm going with 4.0 ft3 vented enclosure tuned to 19Hz.
Also, according to John, the cut size for the driver is 11". The countersink diameter for the outside of the basket would be 12.5". In case you want to get started before the driver gets there.
has any one herd the av12 in use? how do the speaker play low? loud? tight? boomy? i have a velo ct120 and 2 old klh speakers with 12 in woofs curent in my ht
Yes. It's all of that and more. it's rely rely guder thanh mohst.
Jack I am guessing that was suposed to be a
Hey I played my AV-12... Free Air on my floor
It wasn't boomy at all (In fact there wasn't much of any
sound LOL but there sure was a helluva lotta cone excursions
I'm still undecided on whether to build my DIY sub or upgrade the original SVS driver in my truck. I don't spend a whole lot of time in the vehicle....waste of $$$ and a good sub? For the home, I already have two Mission 700AS subs (1 not currently in use since I live in an apartment). Anyways, I will definately find a use for it, somewhere, somehow....maybe build myself a furniture grade subwoofer...hmmm.
