I am desining and building a speaker box, and i'd just like a general answer to this question so i can incorporate the correct volume into the box:

Which setup would make the most/loudest bass:

An entry level 200Watt RMS 15inch sub powered by a 200Watt RMS amp or a comparable 12inch 350wattRMS sub powered by a 350watt RMS amp.

I have no idea about how either would sound and would like some input so i make the best decision.
Thanks

 

I'd go with the (unlisted) dual 12 option.

 

That would be nice, but i'm pretty set on having only one. Infact my design was inspired by one i saw on the boards with the speaker mounted in the center of the box facing the hatch motor with the amplifier recessed into the top of the box, so there's no way of cramming dual 12's in that setup.

 

Won't you be underpowering that 15?

 

There's way more to this than what little information you've provided. What's the sensitivity of the drivers? What's the impedance of the drivers? Who makes the amp? Is it low ohm stable?

Too many variables.

With such a low power amp, you should be looking for subs with a high sensitivity rating. If you can get a mono amp, then you can get a DVC 4 ohm per coil sub and parallel it for a 2 ohm load. This will get more output from the amp.

Everybody builds a stereo from a bunch of parts. You need to build a good system for good results. Everything needs to be well thought out and well matched. Most importantly, your goals need to be identified ahead of time, and you need to adhere to them. Otherwise you have a mismatched pile of crap.

 

The 15" setup components:
rockford fosgate p115s4 4ohm 90db sensitivity with 200maxRMS

mono profile california ca400m 200x1RMS at 4 ohms

The 12" setup components:

infinity reference 1230w 4ohm 90db sensitivity with 300maxRMS
sub link

profile california CA400 300wattrms bridged at 4 ohms

Thanks for the help

 

Anybody have any ideas? I have no clue how a 15" driven by a 200watt amp would sound.

 

its all in the install....theres no way to really tell which will be louder in reality. Only on paper. Ive done quite a few installs for friends who are tight on money and you can make a 15 sound really good with minimal wattage (or any sized sub for that matter)

 

Like this " boom, boom ,boooom, boom, boom" with maybe some thumps thrown in there!

Seriously what are you talking about? Just do it and you'll see. How is anyone supposed to tell you how it will sound? Just make a box with the correct air space for the sub. Use correct gauge wire for the amp. Use some good speaker wire. And please dont throw the sub box in the back seat.

The dvc 12 is a better option imo for these cars then a 15 imo.

 

spend your monry on quality, period. you will be so much happier (and louder) in the end. Ive had so many crappy amps and speakers that Ive learned that spending more will make that much of a diffrence. Spend the money you would on 15's on 12s of higher quality(sp?) and get the best amp you can possibly afford. All in all the better the amp the better it will sound regardless of the speakers, spend the money on the amp, and when you blow the speakers get new, better ones. Amps are the most expensive part of a system for a reason, they make all the diffrerence.

 

in general id think a 12 inch would be better when you wanna do a budget setup, more power to a little bit better 12 will sound better (too me) because i dont like 15's pretty much at all...

 

I've had mixed experiences with 15" subs. Basically I really like a 12" sub for the following reasons; a 10" sub is really tight and punchy giving you tight accurate sound, but is limited in frequency responsiveness. A 15" sub has frequency covered, it can really rumble, however isn't near as neat and clean as a 10", making it sloppy in comparison. Now, the 12" has got your bases covered; big enough to "go deep", but by no means sloppy. I think it's a perfect size to cover a lot of musical styles, which is also something to consider. If you specifically listen to a certain style, then that may persuade your choice, otherwise a 12" is a very versatile sub. Now I have heard "accurate" 15's and "deep" 10's but this is just based on my experiences.

 

it really depends what you're going for as far as your SPL/SQ mix. There are 10s out there that will hit harder than 90% of 15s, and 15s that have better SQ than almost all 10s.

out of those two choices i would go with the infinity because ive never had a bad experience with their products.

 

hey boomin where did you get your alternator from and how much did it set you back? 280 amps is incredible.

 

My setup incorporates a Solobaric L510" w/ 2 ohm DVC, so it is running at 1 ohm woofer in a Super Bass Ported Pro Box. The amp I am using is a Memphis Baby Bell 5 channel amp. It puts out 55w rms x 4 @ 4 ohms and 400w rms x 1 @ 1 ohm. This setup will really jam and leaves my interior pretty much open.

 

my alt was made by dominik iraggi of iraggi alternators i think i ended up paying something like $550 CDN shipped. He's an established db drag competitor aswell. I think if you do a search over on termpro you can find his email address.
