Alpine Type-R - Let Down By It

[Prowler573 5,000+ posts]

Well, I finally got around to putting my Type-R in a single 12" custom 2.5cu.ft. at 32hz box with a Hifonics BXi 1606D amplifier. It sounds great with quality...but thats it. I was let down by the bass. I had to turn it up to 25-30 out of 45 on my volume to achieve where my 2 P1's were almost at with the P1's maxed out on gains and such. Im thinking about getting another Type-R or just a SPL subwoofer for bass. I have all the quality I want, now I just think I want bass. The Type-R I have now is firing into the cabin, seats down, whole car Dynamat'd, and when I get outside to test the bass/loudness, I was let down compared to the P1's I had. I could actually hear the P1's bass outside the car. I know I sound like a noob praising the P1's, but Im not praising that piece of shit (P1's). I just expected to have alot of bass too. So I guess some people were right about it being a Hype-R. And again, Im not bashing the Type-R, I love it for the quality and such, but I just cant help think if it will be better in a sealed box, bc the P1's were in a sealed, 1.25 enclosure each woofer, and it wanged with settings maxed (didnt care for them, so I maxed the gains) and each only puts out 300 watts max. This Type-R is powered by a amp that puts out around 900-1100 watts RMS i think, 2-ohms.
Does anyone think Ill get more bass with a sealed enclosure? If so, Ill do that till I get another subwoofer, probably a 10-12 inch SPL woofer. Whats your opinions?

A) Why is being heard outside the car (whereas most people see fit to operate their motor vehicles from within the interior of said vehicles...) such a critical point? Just wondering.

B) Sealed enclosures aren't meant for SPL applications //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Well, the P1's, what can I say, they were shitty beginners subs at 150 RMS watts each, of course I was going to expect something amazing with a single subwoofer thats putting out alot more RMS than 2 P1's.

//content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif Subs and speakers do not "put out" any amount of wattage, RMS or otherwise. They accept wattage from whatever source of amplification is powering them. The amp(s) "put out" wattage....not the drivers they are amplifying.

My friend says he double-checked to make sure the sub was wired in 2-ohms, and everything is tip-top.

Okay.

Anybody else? Hmm.
EDIT: I just realized this was in the speakers forum....shoot..I meant the subwoofers.

It happens.

EDIT: My bad, you said P1's. They were in a dual 12" sealed, 1.25cu.ft. each. It gave me the kind of bass I wanted where people hear me coming down the street. With my Type-R, I cant really get that at all.

See above.

If you dynamat the whole car you cant expect too much bass to heard outside the car

Again, see above.

Why is being heard outside so important to some folks?

PS: As for creatre above me, I dont see how he can how 1 ohms, on 2 4-ohm subwoofers? I thought it was only 2 ohms max.

If the two subwoofers in question are of the single voice coil variety he can't. If they are of the dual voice coil variety then to achieve a nominal 1 Ohm final load he would wire them like so:

Yeah, I thought we were past the point where I said I dont care if Im not heard outside of the car anymore, lol.

But thanks for clearing up a few things.

please explain. i thought it would be the other way around

dampening slows down the sound waves makin it less to be heard outside i guess...//content.invisioncic.com/y282845/emoticons/ponder.gif.ec2527b23f1d287b60dcbba54f95edba.gif

With Dynamting my rear hatch, sides and roof with 3 trunk made the bass sound much tighter from the outside of the vehicle. No rattles heard from outside of the vehicle is a big positive IMO. Think of the windows as a port and the truck as the box. It's like using 1" mdf box to a 3/4 mdf box in a hi-spl setup.

So you expected it to be this great wonderful thing?

Do you even know what brought on the Type R Boner? It was TCAB

A Type R and a TCAB are meant to go together, if you have a type R in a TCAB enclosure, then actually expect something from them and for it to be piss loud

if you just have a type R, and throw it in some ol random box , then its just like any other woofer out there

TCAB + Type R's like Yin and Yang man, there meant to be together, if your not running both, dont expect much

Whats a TCAB?

TCAB is a company which imo makes totaly unremarkable boxes made of inferior materials that are way overpriced //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Your joking,right? TCAB boxes were nothing spectacular. There is no magic trick to building a ported box and his werent' that great, sorry. People who purchased them have attested to that.

Why not just build a vented box according to the recommended parameters out of the Type-R manual?

Outer Dimensions: 18" x 13.5" x 16.5"

Vent: 12" x 1.25" x 22.75"

Gross Internal Volume: 1.7 cf

Might be worth a shot.
