simple question :)

Recommended Posts

i can make a huge ported box tuned to 33hz and a smaller

one tuned to 33hz will they sound the same ?? and whats the difference ??

Not at all.. The best way to realize things that happen is using modeling software, the effects will vary depending on the sub.

The responses already given are all that is needed:

1. No way they will be the same.

2. The difference will depend on the subwoofer used. Modeling software with the subs t/s parameters can help you predict, but then you also have to factor in the vehicle.

Current system:

1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s

Previous systems:

2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz.

1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.

That's the important thing. The sub will be a factor, but even more so how that sub in a specific enclosure and how it reacts in a given environment.

Tell me...does this smell like chloroform to you?

Just sticking with the subs recommended specs is what I'd do.

Not really applicable. Think about subs that can be used anywhere from 2.5^3-6^3. That's a big range

Plus the manufacture's recommendations are always best. They are looking at many different factors when they make those recommendations.

And as TeamHT said - they normally give a fairly wide range. Knowing what you want from the sub will be a big factor in selecting a box from that range.

I think this question is purely theoretical:

So just focusing in free field (like outdoors) normalized frequency response, here is the Alpine SWR-1243 all 3 boxes are tuned at 33Hz:

Red line is 6 cubes net.

Yellow line is 2 cubes net.

Green line is 0.5 cubes net.

As you can see it's the same sub and the same tuning but the response is significantly different due to net volume differences.

Going beyond your question the box design, location, the vehicle itself, electrical system, tone controls.. etc, will have a significant real world effect on performance and that is specially true inside vehicles.
