Ported sub enclosure - Transient response?

[Biowaste 0]

Hello gents,

So all these years I've been a sealed enclosure type of guy. I listen to bands with lots of double kick and I enjoy it being deadly accurate.. However, I did hear a ported 12" this week that has me rethinking some things. The guy played me Megadeth's "Rust in Peace" (remastered) album and the sub seemed to do pretty well keeping up with the double kick.

However, how would the transient response be for even quicker metal bands? (i.e. Divine Heresy, Wintersun, Nile, etc..)

Would it stay somewhat accurate? or would it turn into a more muddled response?

Or... is it dependent on the frequencies of that particular kick drum(s) and/or be dependent on the band/mix of the CD?

For you metal guys, what port frequency tuning works best for you?

Thanks,

Your midbass will have the greatest impact on achieving the double kick drum sound you're going for

With that said, I run 2 RL-i8s sealed and they sound excellent

My plan was to run some PG rSD 6.5"s comps installed in properly sealed and deadened doors and to cross them around 75hz. That, plus a 12" either sealed or ported in the trunk.

Do you think that would get me the midbass I'm looking for? In the most cost effective way of course...

I'm heavily considering just dumping the kick pods and running an a-pillar/door setup. Over the years, imaging just isn't very important to me while driving. The time alignment on my HU should be enough to satisfy my listening needs.

Thanks man!

I'd want to cross lower in your midbasses if you are truly looking for fast kicks. In particular for metal.

seems like alot of ppl are picking up the pg Rsd's. including myself. im basicly gona be runing the same set up as you(pg's and a 12). my sub is a 12" aa arsenal runing sealed. my head unit is a sony POS but i just try to work with what i got. gona be geting some deadening for the doors too.

i have my sub in a ported box just for fun right now. its pretty accurate. i always thought ported would sound like chit but i think a better sub installed right would sound pretty good.

the Rsd's will be in next week and will be runing a kicker kx250.2 to them.

60hz? 50hz? I just hope they'll be able to survive it.

Thanks,

Man, I tell you... I was in the market for some new components anyway. The Infinity Kappas I have now are very close to retirement. For $80, I said what the hell and took the plunge. If they aren't for me, then I can sell and replace 'em.

Be sure and let me know what you think of them!

My mids are crossed at 40hz and do an outstanding job with the fast metal...not the reason I have them, but noentheless I have a collection from my past that periodically gets played. In the price range you are at, I'd highly suggest the Pio 720's over the Rsd's for your application. Way stronger midbass.
