  2. Mal-X 21" - sealed or LLT?

    DIY Subwoofers - General Discussion
    I'm thinking about a build with a 21" Mal-X. My first reaction was to build a sealed cabinet - because I've been very happy with the performance/sound of 6-8 cuft sealed cabinets that I've built. That...and I love sub 20hz content (below tuning point of most ported). But, every time I model...

    Ported Subwoofer Build Projects
    So I have a Mal-X 21" and an EP4000. Would like to build a sub. I am no good building boxes so I will use sonotube and I am thinking sealed. QUESTIONS: What size enclosure so I do not need HPF, if possible... Wired series, parallel, bridged amp etc. Anything else you would do? Thanks in advance.

    Classifieds - Speakers and Subwoofers

  8. Mal-X horn folded?

    DIY Subwoofers - General Discussion
    I've been looking at mdrake's Mal-X horn specs, and wondering how I could fold the 96" long part into 48" or less. My goal dimensions are 48" long (half the 96"), 40" tall (twice as tall as before folding), and 16" deep (I think that was how deep it is.). Is there a way that you can fold a...

  13. Dr. Geddes - Bandpass Theory - Mal-x

    DIY Subwoofers - General Discussion
    Below is a quote from Dr. Geddes regarding bandpass enclosures. I can not get my brain wrapped around the statement in bold. Can someone smarter than I explain? On paper, the designs usually cover about 1-2 octaves, so thats about 40-100 Hz. But when I measure them in-room they tend to be much...
