Hello, I'm new here and searching the forum for a couple of days without finding an answer to my question. So here it is:
I'm heaving trouble deciding which sub to buy.
I've got a lot of experience with various brands like RF, alpine, JBL, Kenwood, Clarion.
My current setup is:
Kenwood KDC-W808 (5v preout)
Kenwood KAC-8401 (4x60W@4ohm)
Kenwood KAC-8151D (1x400W@2ohm)
Macrom SE2.60 2way (6 1/4")
4x Macrom 59.10 midrange (4")
2x 12" Kenwood KFC-W3009
1x 12" Rockfort Fosgate RFR2212 DVC (too much is not good for me!!!)
Recently I bought myself another car. A Swift '94. And it's small. Real small.
So the problem is, I heaven't got enough space in my trunk. And I really need to leave some useable space there. I don't want to use any of the subs I have.
I tried to use my RFR2212 but I always end up with a terrible headache. Even when I don't listen at high volumes. It's just an SPL sub, and I really want SQ!!!
The Kenwood sub doesn't sound right in a small sealed enclosure (0.85 cu ft). Both of these subs only play well at higher volumes. But most of the time I want to listen at lower levels.
Here's what I made up:
I want to order a Polk 8". Just one! And place it in a sealed enclosure. My Kenwood KAC-8151D (1x400W@2ohm) is a bit heavy but there's a good stable signal from the HU. And with the input sensitivity at 5v (minimal gain) I think the Polk 8" will play just fine. I know fore sure my amp runs best at 2ohms.
So which Polk 8" to choose: the db840dvc or the mm840dvc.
In the Netherland these subs are relatively expensive and I've got a small budget.
db840dvc sells at €89,- and de mm840dvc sells at €139,-.
My first choice would be the MM, but I noticed that a ported enclosure is not recommended. That could be a problem when I want to switch enclosures in the future.
So right now I'm thinking of buying the db840dvc. But I only can find a box plan for the old db804.
Is 0.35 cu.ft. not a bit small? The MM840 has plans for both 0.35 and 0.68 cu.ft. The 0.68 gives me a better feeling about the result.
That's a lot of question for one thread (sorry), but here's a summary:
Will one 8" sub give a nice "add' to my SQ system?
Is one 8" sub suitable for my D-class amp?
Is my choice for the DB840 good, or should a MM840 perform very much better?
Which enclosue to build for the DB840 or MM840?
I've NEVER heard a polk playing, but because of the threads I've read so far, I'm sure they'le be just fine for me!
