Ok, bare with me this is my first thread but been searching the forums awhile and I can't come to an conclusion and its driving me First finding a 8" Free Air/Infinite Baffle sub is hard enough but finding one that can produce 30hz and handle atleast 150w rms seems to be impossible. Below is all I can find but still not what I want

 

i know you're wanting to go with an 8 inch, but im sure slim series 10inchers would be easier to find? maybe? if it were me, i would just do some fun custom work and put a ten in there :-)

 

Yeah your right I think I will have to get creative. Thought i could take the easy route.

 

that would be an awesome little custom setup...a ten on the back deck... i wouldnt think you'd run into many if any at all rattling issues puttin a sub there too

 

1 underhung DLSOA10 in the stock location. It will handle that power and give you the response you are looking for.

Yes I have seen it done. SC2k1 has pics here somewhere.

 

DLSOA10? I tried to google it and can't find it

 

Thanks, I seen you mention that in another thread where can I find one?? tried searching but not much luck

 

Here is the home page:

Here is a link to the OA10:

If you have any other questions, shoot.

If you want impressions of the driver, other than mine, you can contact SC2k1.

 

Another option I seem to always neglect to mention is, Fi can easily modify the ssd to operate IB. I have done a pair of 10" IB ssd's in a G35coupe. I will find the pics if you are interested in going that route.

 

Here. These are the Fi IB ssd's with Havoc dust caps. This style dust cap was used at the customers request b/c the front of the driver would be visible. But the one you would order would come with the standard FI logo dust cap. These are pics before the install was finished. But you get the idea.

 

Thanks for the help!

 

Anytime.

 

That's 1 helluva setup. Very nice!
I found this video on youtube: http://www.youtube.com/watch?v=MxtD5hNSU-8

 

Yep, they can get the job done.

 

I check DLS site and seen they also have the OA8 that seems to fit my needs to the T so think I will go with that. Also found this review from nismos14

http://www.diymobileaudio.com/forum/...n-hx2-cvr.html

So I think I have my setup: 2 sets of 6.5 kappa perfects componets, the OA8 in the rear and the G4500 feeding the componets a conservative 80w each and smaller amp giving 150-200w for the sub. Hopefully both amps can fit on the back seat and Ill have a decent setup and full trunk space.

 

dls oa8 and image dynamics id8 come to mind as the top subs i would try.

/thread

 

where are the prices on these subs? as well as the OP, i've been looking for a great open air sub too.

 

PM or call Don, Pearl96Max for prices. I don't think they are pricey at all IMHO.

 

Yeah ask around or you can try looking on the web. I found the DLS OA8 on a couple sites for round about 100 bucks shipped. So the OA10D shouldn't be anymore than $150-$200 if that

 

Be weary of fakes. I am not saying the sites you are looking at carry fakes, but there are more out there than you can imagine.

Don=Pearl96Max=6spdcoupe, just so you know.

 

your right filtor1, I pm'd Don I guess it doesn't hurt to support a fellow org. member i told him you refered me so maybe you will get a refer a friend discount

 

I can only hope so.

 

why do u want 150rms, u can get a kicker C8 it handles 100w rms and with a nice amp and dynamat on the rear deck u get a lot from that little sub.

 

Other good options are the Cmass SS82, and Kicker CVR's. CVR's get loud iwth little power, C-mass's handle a bunch of power.

 

Like you have used any of those...

 

Idk 100w doesn't sound like enough from what I have been hearing free air subs need as much power as they can get because the lack of a conventional sealed or ported box. But don't quote me I'm not an expert

Speaking of though quick question for the audio guru's might be dumb but the OA8's are 8ohm's I believe. So can I use any amp? and if so would it be less than the rated wattage example: @ 4ohms = 250watts so would 8ohms = 125??

 

subs run free air generally need less power to reach full excursion.

8 ohm speakers will see half power, but it's not just that simple. sensitivity also comes into play as to how loud the sub will actually be.

 

Yep, free air requires less power.

 

do you really have/want to go IB? why not just use 2 10'' and make a box for each that mounts to the bottom of the shelf. then you get your saved space + better bass...

 

^ not everyone wants / needs that monster bass. A single 8 or 10 free-air is more than enough to the average listener.

 

Yeah i just need a little extra thump to go with my sets of componets and don't feel like doing any custom work so sticking with an 8. Just glad to find out that it's alot of options out there. thanks again filtor & nismos

 

Anytime.

 

true but don't IB have poor low-frequency bass and it will not be very accurate or defined. but i suppose for the average person that's fine.

 

IB setups usually player lower, they just don't get as loud. In my experiences anyways.

 

Quite the opposite.

 

 

following for information

 

From: http://www.termpro.com/articles/subwoof.html
"Unfortunately, there are several disadvantages to the infinite baffle. When a speaker is mounted in an enclosure, the air inside the enclosure acts like a spring against the speaker cone, and he resulting buildup in pressure provides mechanical damping and prevents excessive cone movement. But an infinite-baffle installation does not use an enclosure, so the mechanical damping is poor, resulting in "hang-over" and lack of definition. The power handling of the speaker will also be compromised since the infinite baffle provides very little control over cone excursion."

is term pro not a good source for information?

also i googled and just found this:
From:http://www.mobileinformationlabs.com...e-baffel_1.htm
"Disadvantages of this design are difficulty (sometimes extreme) in completely isolating the two sides of the cone from each other, and slightly less accurate sound reproduction."

granted they could be wrong but is there a finite answer on this subject?

 

I've liked the sound I got from my IB enclosures more than boxed setups. The accuracy in every instance was great, I never suffered a loss in that department. I've also had no issues with cancellation and my 6 or o IB setups have all had some anomolies as far as power handling goes.

Some handled rated power + some handled rated power, some handle way less.
