Well, I built my first pair of folded corner horns in 1970,

In Reply to: I've been building sealed subwoofers since 1980 and disagree with most of your conclusions posted by Richard BassNut Greene on April 13, 2007 at 07:10:02:

so don't give me any of that seniority crap. How do you know better than I do how my speaker sounds?

I'm trying to encourage people to break away from the standard commercial overpriced junk and experiment on their own, and most people will obtain far better results from a poorly designed sealed enclosure than they can get from a poorly designed or poorly executed ported design.

There is plenty of bass available from one 1259 in a sealed enclosure. Your proclamation that only one is insufficient will merely discourage people from experimenting.

I'm saying that the reason more (almost exclusively) ported designs are available is that manufacturers can sell more and get more profit from small ported boxes with faked bass than they can get for a larger sealed enclosure with excellent bass. The industry has moved away from quality toward convenience and WAF, and I'm trying to make experimenters aware that there are valid alternatives to the complexity of designing a ported enclosure.

I'd like to see some support for your argument that a ported design costs more to make. How can it cost more to build a one or two cubic foot box and put in a crappy driver, low-power amplifier, and a plastic pipe to make a ported enclosure with boomy bass than it costs to build and ship a three, four, or more cubic foot sealed box with a quality driver that requires a more powerful amp?

The difference between the average ported box and a quality sealed box should be readily audible to anyone listening to any kind of music. The sealed box I just built sounds better than the REL Stadium sub I was using, and I think that REL makes a pretty high quality piece of equipment.

Who wants or needs another half-octave below 25 Hz? How much musical content is there at 19 Hz? Mostly all that can be heard is traffic rumbling and stage noise. And what ported enclosure (and what room) can produce 19 Hz?

Thanks for your disagreements. Inmates who frequent this forum are probably not surprised that you know more than anyone else, even about the sound of their own system.

Peace,
Tom E
