Is this sub built to be ported or sealed??

I do have winisd but i dont understand it. nor what it means or what those numbers means to real life music.

8 of these would not sound any good???

For $300 for all 8 its hard to pass up, Ive just een these vids were everyone says they pound and sound good, but theres no box specs or anything on any of the vids nor can I obviously hear what it sounds like

They probably do sound impressive to the ametuer ear, and so far thats all I have seen using these //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

WinISD wise, accurate sound reproduction (ear pleasing good sound) is the result of a nice freq response. the lower the deviation the better. Freq wise (un-eq'ed) the idea would be to run them from their loudest note down 3-6dB and same for the upper end or from 38Hz to 120ish. For rock that would probably suffice for anything without a decent bass guitar line because the subs will not only be excessively muddy (based on published TSP's) it will also not be very transient or have a low F3 (30Hz or so). The subs have an F3 of 37Hz in 18 net for the 8 based on TSP's and a Qtc of 1.02 (.7 being optimum for slowest roll off and most natural sounding reproduction.) Ideal response for a daily driver is as flat as possible and a low F3, or a +1dB wide band of gain around the most used freq's (35-50Hz) the HFi12D4's gain in 18 net for the 8 subs is around 53-93Hz. Ebay has them for 37 shipped, If you wanna pick one up and send it to me I'll pull TSP's for ya and get you accurate info on them. If they are way off (to the bad side) you'd benefit from knowing not to buy more, or on the other hand have the confidence that the build isnt going to sound as bad as it plots, lol. I'll pay shipping back to you just to have gained another set of TSP's.

That was a good read thanks, you obvioul know what your talking about

I suppose I have an amatuer ear aswell as I dont know much about eq or roll off or anything much like that.

I was just looking for a change from my AQ HDC3 18's that I blew and I wanted a new wall with new subs instead of reconing them....

They just seem to have great output, and since I dont chase numbers and this would just be for my ride to work fun lol

I dunno what to do

 

[audio_phill 10+ year member]

Wow, you blew HDC3 18's?? We ran our coppers on 2500 per, daily with no issues for a long time, lol. I guess it would be budget fun, but its gonna be budget response as well, lol.

Any other opinions on personal experience with these subs and hearing them??

 

[AudioDave]

20 years of wall building want my 2 cents? Look up my pics. I used to rep for them I got the box designs, dimensions etc. What amps u using? What kind of vehicle?

 

[CoilBurner]

If I ended up going with the 8 of them. Id be using a sundown 3k on all of them. Going in a nissan pathfinder

 

[AudioDave]

in the entire back area or? Specs on the sundown or is it the SAZ-3000D

 

[Qxxx4]

Youve never heard them in person?? They bang prety good and sound pretty nice actually, 8 would horribly hurt

 

[AudioDave]

? ok?
