Even amped 6x9's can't come close to subs bass-wise in terms of volume and sonic range.

From what you guys have said it sounds like I can really accomplish a lot by just getting a better box. I have a sealed box now, but I don't think it's truly sealed (no silicone in the creases or around the terminal cups). I think I'll try to borrow a single box and see how it sounds pointed correctly like Nismos suggested.

This is my new favorite forum, you guys rock.

 

gently push on the middle of the cone and report back what you find...

 

hurt my feelings it was like 7-8 hours to get my germs...sigh

 

Nothing to speak of that I could tell. There was there was a pretty high amount of resistance in the travel. It didn't make any funny sounds or anything.

 

Sounds like the box is sealed up fairly well. Just try another box single sub action see how you like it... worst case you decide to go with more powerful subs (sub).

 

yea hoenstly I would go with a sealed box if you listen to alot of rock. I know in my case I listent o everything so sealed made sence. If you listen to rap or techno on majority you can get away with a ported system and gain alot more boom with no real noticable loss.

 

Low tuned ported can be just as clean/accurate as a sealed box.

 

^^so true!

 

I have heard such but ehh still the sealed or me

 

I would prob stick with ported if I were to go back to an enclosure again.

 

Yes but as you fill it, your woofers FR curve will change......

Unless you have a vent somewhere in your trunk.

 

Ehh.......Group delay will still be higher. I have a ported sub in my room that I built myself and the increased delay is obvious on faster passages. Yes, it very well could be error in construction or problems with room interaction, but the math says group delay will always be higher (with the woofers I've got). I say get a high(ish) QTC woofer and put in either an IB or a properly sized sealed alignment so you get an F3 point right about 25hz. Nice and smoooooth bass.

 

I have one 12" Kicker Solobaric (the square one) and it pounds hard. I have had nothing but kicker subs in the past and have had no major problems. Best subs in my opinion.

 

Where did you get the information that led you to this conclusion?

FYI, 2 10" subs have 620cm^2 fo surface area.

1 15" sub has a surface area of 810cm^2.

Given they both have the correct power and the correct enclosure, the 15" will have a measurable advantage in output.

 

More room for the bodies.

 

To the OP, what is you 'actual' budget. Also, what is the model# on the Alpine amp you have?

 

My amp: MRP-M650
http://www.crutchfield.com/S-21rcTVW...p?i=500MRPM650

I'd like to match the RMS within 100.

As for budget I'd like to stay around $150. I get lots of stuff off eBay.

 

It is going to be very difficult to "upgrade" withing that budget. The next step for you will be a bit more costly than your budget allows.

 

So a $100-$150 12" sub (Alpine Type R, Eclipse Aluminum, Kicker Comp, JL W3) wouldn't be an upgrade from my two Type S's?

I guess the next big question is, how much a hit would I be taking by switching to one of those single subs? Like, "I won't notice, I'll notice a little, I'll hate it."

 

Does your budget include what you'll get when you sell the Type S subs?

 

The subs you listed above would not be enough of an improvement to make up for the lack of displacement. Out of the list though, the JL would sound the best. This is just my opinion. Take it for what it's worth.

As far as taking a hit, when you cut your cone area down by 50% and keep the same power, you could see around a 3db loss in output. That is not the gospel as far as loss, but it is a starting point. Will you notice? I can't, nor can anyone else tell you the answer to that. Chances are good that you will.

The question now is, are you willing to take a hit in output for the gain in trunk space. None of us can answer that either.

 

Great question. After factoring in the additional money collected from the sale of the current subs, we could start suggesting some better drivers. This is assuming that your $150 did not include this already.

 

what about your diamonds?

 

Cool... that gives me something to think about. Thanks for the perspective.

Good point, no I did not factor that in. I Imagen I could get $75 for the pair with the box. If that was the case I'd be willing to bump my budget to $250. That's still without an amp upgrade, but I could wire it at 2 OHMs instead of 4 to give me 600 RMS.

 

They are still sitting here in my office. I have no idea what I am going to do with them.

 

ment 2 12's wasnt paying atention when i wrote it. but there are a lot of veriable involved in it too.
