Is anyone familiar with RE Audio SRi10 subwoofers?

[porksoda 10+ year member]

Well I saw these on sale and I am thinking of buying one for my daily driver build(1992 Oldsmobile 88).

Does this look like a pretty good subwoofer?

I really like the price! ($50 shipped!)

I dont want to shake windows with this system but I just want a little system.

Subwoofer:

interesting... this is listed as a different product than the SRX. I wonder what the "I" stands for. Maybe a special black friday promo item just renamed?

they are very impressive woofers as is all of re subwoofers in my opinion. we did one in 2.5 cubes at 32hz on a powerbass 1000.1 @ 2ohms and it got nasty. def the best bang for the buck no doubt.

Would this be any of a step up from an RE10? I see it has a bigger magnet and 18mm Xmax as compare to 12. Also, which would be louder, 4 of these sealed, or 2 ported in 1 cube @35hz?

tune lower for those, like 28-30hz @ 1.5 cubes, if you want any type of reasonable comparison.

and it depends on how much power you'd be giving them. there really isn't any straight answer to that question. if efficiency is your concern, go ported.

Really doesn't seem to be any straight answers in car audio except for the obvious I guess haha. Ok, let's put it this way, all things equal, box and power, would there be much difference between the two? Or would getting a SE-X be the next logical step up? I would get the SEX but my lil' alternator won't be able to take 300 more watts.

 

[porksoda 10+ year member]

I ordered one today. Ill review it when it comes in.

 

[mobileaudio219 10+ year member]

I ordered one as well... guess we'll see! For 50 bucks, if I don't like it I can sell it locally and not lose anything...

Yes I realize you are asking a hypothetical question... but such a question simply won't work. For example, the optimal sealed box won't be the same size as the optimal ported box for the same driver. All things can't be equal. However, four sealed (usually for sound quality) subwoofers are a little gratuitous unless they specifically meet design requirements (you aren't going to go into that level of detail).

I haven't heard of too many people running four sub sealed. Hands down, go with ported. They will be more efficient ~Subwoofer Box Enclosure Design Calculator - Sealed Ported Bandpass Closed Vented on that site you can see the direct comparison in frequency response. The story it won't tell you is impedance, group delay, phase delay, etc. Transient response is said to be overall better for sealed enclosures but better around tuning frequency in ported enclosures. I've never had the time or resources to do any side-by-side comparisons but i've never noticed an audible difference in sound quality between two properly built ported/sealed subs.

I used to run four 12" of the origial AA Assassins(TC2+ motored)...really sounded great, but I was dumbass and sold them ~3 years ago and regret every minute of it. I actually plan on doing either a sealed or passive radiator setup next.

Well I check my tracking number and it says my sub will be delivered tomorrow sometime so I will get pictures when it comes in.

 

[AWD PSI 10+ year member]

Have you decided what kind of box to use? I think I want to try ported. Should probably email RE and see what they say about it.

 

[porksoda 10+ year member]

I think I am gonna do a ported box. I am gonna get RAM_Designs to do it for me.

We have spoke a little about it already.

 

[AWD PSI 10+ year member]

Mine just got here. Nice looking sub. The instructions list box specs the same as their website does for REX.
