  1. IB installation question on wall bracing

    IB - Infinite Baffle Subwoofer Build Projects
    Hello all. I have a 15'x20' theater room with a vaulted ceiling and dormer windows. Due to the way the interior was finished, I have two fully enclosed (drywalled) areas in the front of the theater room, one on the left wall, and one on the right wall (symmetric) that I want to use for an IB...
  2. Klipsch Quartet Mods

    Two Channel Audio
    Hi All, I'm picking up some Klipsch Quartets and am thinking about updating the crossovers, diaphragm and adding sound damping materials. I've seen a little information on bracing, and very little on damping. Can anyone share with me what the benefit of bracing would be; and if use Black Hole...
  3. When is bracing a subwoofer box necessary?

    DIY Subwoofers - General Discussion
    I'm about to build two ported enclosures for my new Sundown Zv4 12 inch subs. I'm in the planning stages and realized my least favorite part of building subwoofers is the interlocking bracing. At what point do you not need to brace the insides? I'm thinking about building the walls of the...

  5. Small sub - Do I need bracing?

    Sealed Subwoofer Build Projects
    I'm building a 16x16 sealed sub out of 3/4 inch mdf and was just wondering if I still needed bracing in the center or if it was small enough to get away with none. Thanks!
  6. Bracing the port tube?

    DIY Subwoofers - General Discussion
    IS it recommended to brace the port tube inside the enclosure? I will be using a 4" Precision Port around 15" long. Should this be braced in some way within the box and not just attached by the screws on the outer flared end. I would imagine a port tube could move/vibrate around quite a bit in...
  7. "BRACING" ...How important is it REALLY ???

    DIY Subwoofers - General Discussion
    Has there ever been any real testing on "BRACING" to actually Hear, or for that matter Measure any real difference in SQ ?? I've seen a High End (Big curved,Sealed) enclosure here, proffesionally build with looks like minimal Bracing,for the enclosure size, and have read other SUB designer that...
  8. Sub Bracing

    DIY Subwoofers - General Discussion
    Obviously this is not a precise representation. :o Comments on this bracing idea? The shapes, amount, etc. of bracing - not the wood type. 16 Dowels The large brace in the center Corner pieces 1.5" MDF for the box. 2 passives, 1 sub, 1 plate amp = 4 sides are taken. Front (sub) removed so...
  9. Upgraded bracing

    Ported Subwoofer Build Projects
    Hello again, I just had a question thread going about retuning my cabinet here. http://www.hometheatershack.com/forums/diy-subwoofers-general-discussion/53377-sub-replacement-now-what.html When I had the sub apart I upgraded the bracing inside. This had been recommended to me when I first...
  10. Bracing material question....

    DIY Subwoofers - General Discussion
    Can you use 1x4 lengths (fir) for enclosure bracing? I notice most people use the same material as their enclosure and then cut out holes/windows.....can 1x4's be used instead? Glued together to make "crosses" and then secured inside?
  11. Bracing for 22" cube box

    DIY Subwoofers - General Discussion
    For my upcoming project, I'm going to run one vertical and one horizontal brace. Is it better to have one run left to right and one front to back or can they both run front to back? I have seen people do it both ways, but was wondering which was better?
  12. Mid/bass driver damping and bracing

    DIY Speakers
    I am designing a slot port enclosure for a mid/bass driver with the assistance of Bassbox Pro. The response needs to be from ~60-5000 Hz. There will be no internal crossover. I have a couple of questions. Which is better at killing low frequency standing waves? Blackhole 5 or No Rez? Is...

  14. questions on bracing and internal volume

    DIY Subwoofers - General Discussion
    If the internal dimensions of my box are 24" x 24" x 58", how much bracing do I need? Should I have bracing width-wise and length-wise? What if the internal dimensions of my enclosure are 24.5" x 28.5" x 49" ? How do I figure out the volume of the Mach 5 IXL-18.4 driver? I saw their page for...

    DIY Subwoofers - General Discussion
    Is one preferable over the other for subwoofer shelf bracing? Or is it a wash? Drawing up my box now but not sure which to go with.
  16. Which way to install bracing in this box

    DIY Subwoofers - General Discussion
    If I have a box that is 33" wide X 19" Deep X 14" Height how should i install bracing? Should i install one long brace that goes vertically across the box so that would be approx 31.5" X 12.5" or should I install 2 braces going vertically that would be roughly 12.5" X 19"? Thanks
  17. Internal Bracing

    DIY Subwoofers - General Discussion
    Is it necessary to round over internal bracing cutouts. I've have several 6.5" holes cutout on my main internal brace in a 3cuft. enclosure. Similar to the example used in the Enclosure Calculators.
  18. Rebuild cabs or add bracing

    DIY Speakers
    As seen in a different post here I have been playing with rebuilding\improving some existing speakers. I have gotten my waveguide where I am happy with the response and am ready to work on the boxes. The boxes are 1/2" particle board with some sort of a composite plasic front as seen below...
  19. Do sonosubs need internal bracing?

    DIY Subwoofers - General Discussion
    I'm in the middle for my sonotube (Formatube) sonosub build. I just got the tubing today and have cut it to size. However, the walls look very thin - about 9mm (3/8"). The 610mm diameter tubes are cut to 1390mm long each. Should I internally brace them or not? Will the walls resonate if I...
  20. Bracing subs (XO < 100 Hz)

    DIY Subwoofers - General Discussion
    At 100 Hz, as long as the biggest box dimension is < 1.7 m (5.6’), potential panel resonances will be above the panel sizes. In that situation, is there a benefit in bracing? Thanks
