how do you think these would do sealed in the low-range? like my L7's started to rolloff around 35hz and under... i assume 2 sealed 18"s would murder 30hz but i dunno?

They have low end potential //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Just don't expect much in the way of killer transients...

what does this mean haha

judging from its specifications it doesnt seem to be quite the low end monster...

other than having a huge surface area, nothing else is really going for it to displace any amount of air at low frequencies.

low xmax, high Fs, and mid Qts for low end...//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Don't expect it to sound all that good //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I don't think anything can be a monster for that price //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif I'm doing something dangerous and going by the 12" results, which probably is the wrong thing to do...the lack of displacement is going to hurt it, no doubt, but I'd go with a low Qtc alignment to make the most out of what's there.

 

[thadman 10+ year member]

Yeah...

modeled it in WinISD and got an F3 (-3dB) of 65-67hz (6 cubic foot box to help the low end, mind you)

(I know WinISD isnt the end all be all or anything...but that should give you an idea of how much it sucks at getting low, not SPL just low-end performance)

the Kicker L7 12" had an F3 of about 35-36hz...so if you're hoping this is going to get lower you're not looking in the right place.

would i be better off going with like one Audiobahn AW1805Q 18" and porting it?

 

[JimJ 5,000+ posts]

No...

 

[96i30 10+ year member]

audiobahns are that bad huh lol ...i def like the deep bass the kickers offered...but i also like the loudness...if the 18's im mencioning arent going to do the job as well as the kickers the only other thing that would get louder in my price range of like 200 is 2 kicker 15 comps

200 per? If so you are almost into the range of a Mag 15. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

The 18s will do fine, once cabin gain kicks in they wont be too bad. They just wont be low-end monsters and have a bump in the frequency around 20-30hz, response would be pretty flat/shallow roll-off.

im not very knowledgeable on the freaquecies and such... mind explaining this like u would a woman haha

I think the Mach 5 boner grew considerably today.

I'd still like to hear one but those SPL numbers per dollar spent are impressive. No two ways about it.
