  1. UMIK-1, REW & Laptop USB & Audio output ports

    REW Forum
    I am new to testing speakers and setting them up in a room and have a few questions. These are based on using the miniDSP UMIK-1, a cheap(ish) Acer 5742G Laptop and Windows 7 for testing purposes: When using the UMIK-1 will it work with "any" USB ports or must the be of a particular spec? I...

    Has anyone tried the 4" Dimpled Precision Port? Do they really allow for higher air velocities / have less turbulence over the smooth version?
  8. Port volume with roundovers?

    DIY Subwoofers - General Discussion
    I don't have the pleasure at the moment of doing a build, but am kind of figuring out the process for executing one successfully for when I do have the opportunity. When you are calculating or subtracting volume from an enclosure, how do you account for the roundovers on a port? Is it the...

    I've been procrastinating to build some subs and not sure whether to use slots or round ports when I will finally commit:whistling:. I havn't seen much in HTS concerning slots so please excuse any ignorance coming from the following questions: Can a slot can take the place of one or more...

    Ported Subwoofer Build Projects
    I have decided to take Thomas-W's advice and build a manifold on my door to house (4) Fi IB3 18's on the top and make 2 slot ports on the bottom out of the rectangles already there. The door is 1.25" thick, I will make a template/face of the entire door adding .75" to the thickness. I'll make a...
  13. FS: 6" Precision Ports, Enough for 2 LLT Subs

    Classifieds - Speakers and Subwoofers
    I'm going a different direction in my planned subs, and have my new PSP ports to sell. They are light, but bulky, so I'd prefer a Dallas or Houston buyer. If in Houston, or somewhere on I45 in between, I can deliver. So, initially, I'm not offering shipping, but will later if they don't sell...
  14. Leveraging Equipment's USB ports for cooling fans

    AV Home Theater
    With all the new AVRs, DVD players, etc., coming out with USB ports. Anyone ever try to use these to power a laptop coolant fan? I figure this would be a nice cheap $10-30 solution mainly for open rack equipment, rather than spending a whole lot more $ (I'm thinking $80 and above/per) for some...
  15. Why does port length increase when two ports replace one?

    DIY Subwoofers - General Discussion
    As per title, Just wondering why two ports are required to be longer than a single port? For instance if I tune a cab with a single 10" port, but the port velocity is too high and I add another port, these ports are then required to be 22.5" long each?

    DIY Subwoofers - General Discussion
    I have 2 700 liter sono subs using Fi Q18's and an EP2500. Detailed more in the Fi forum. In my fight (or quest) to get audyssey to play nice, I tried plugging the ports by wrapping beach towels tightly and stuffing them in the ports. It helped Audyssey to "play" better (that is a discussion...
  17. Larger Ports affect

    DIY Subwoofers - General Discussion
    Okay I have a ed 16Ov.2 D4. 11.5 ft box. When I look in WinISD it shows port velocity in the low 30's. I've researched and found alot of ideas over port velocity but, in general lower seems to be better. I was wondering if a 8" flared port instead of a 6" flared will hurt anything. How will...

    SVSound
    As some of you know I have had an issue with my PB-13 ports squeaking because they were loose. Ed told me that this was only the 2nd one ever that has done this. Well the issue is now fixed. SVS fixed the problem by ungluing and then regluing the ports to the internal brace. NOW the PB-13...
  19. Dual tuning of ports

    DIY Subwoofers - General Discussion
    Has anyone had experience with dual tuning of ports? Such as one port tuned to 30hz and the second one tuned to 15hz, and is there any software currently that could model such a thing. I know bassbox 6 pro can't do it.
  20. How many ports to fill?

    SVSound
    I just got my PB12 -NSD/2 and couldn't be happier. That being said, I am torn as to which freq to run the sub at? Since this is my first nice sub I am not too familiar with whether to plug 1, 2, or zero ports. Any thoughts?
