  1. Will REW work with a display port cable vs an HDMI

    REW Forum
    Hey guys, it's been a while since I have been here. I just upgraded my subs to dual SVS SB16 Ultras. They sound great already but wanted to see if their onboard EQ can tweak the last bit of sound for me. My Microsoft Surface laptop doesn't have an HDMI out, but uses a display port out, which...
  2. Question on port design/modeling

    DIY Subwoofers - General Discussion
    So backstory: built a wall shaker in my college dorm days with help from here (thanks!), but now I'm married and in a tiny-*** Northeast US "apt" (really a converted house). 6.4cuft behemoth had to go, but I kept the parts. I convinced myself I was going to build a 3cuft sealed and be happy...
  3. Port Timing

    REW Forum
    Both my mains and the sub are ported. I remember reading a while back that ported speakers disrupt relative timing between speakers and subs. Is this true and if so, can it be easily taken care of with external delays provided by a miniDSP or equivalent?
  4. UM10-22 port size?

    DIY Subwoofers - General Discussion
    I'm new to building a HT subwoofer. I narrowed my search down to the Dayton Audio Ultimax 10" subwoofer but something on their page confuses me. They say to use a vented box at 1.75 cubic ft. (net internal, not including driver or port volume) tuned to 25 Hz with a 10" wide by 1" high slot port...
  5. Need help with port length / size based on my enclosure

    Ported Subwoofer Build Projects
    I will soon be embarking on my first sub build, and plan to put the enclosure inside a current wall void. The internal box dimensions that I came up with are as follows; 1.16' wide x 3.256' tall x 2.08' deep. This nets 7.9 cu ft for a Dayton rs5390hf. Don't worry about room between studs. I will...
  6. Port location

    DIY Subwoofers - General Discussion
    Im building an in wall subwoofer that will be positioned mostly behind my projection screen. The subwoofer itself will actually sit under the screen and not be blocked in any way. Normally, I would place the port on the opposite end of the woofer. But in this case, I don't want the port to be...
  7. Port size in Winisd

    DIY Subwoofers - General Discussion
    So, I see the options to change the ports from round to square. I also see where you can change from 1,2,4 etc..... How can I do an 8 inch radius port or a slot port etc?
  8. Subwoofer port location

    Home Audio Subwoofers
    I'm under the impression that subs with downfiring ports are less sensitive to room placement than subs with ports in the rear or front. I have searched and searched for answers to room interactions based on a sub's port/ports location. Is there a general consensus on room placement as far as...

  12. How important is venting port location?

    Home Audio Speakers
    I want to get a centre speaker, but the tv or furniture is going to be right in the back of the port or maybe 1-2 inches. How bad is that going to be? Is it a must to get one with front port? Thanks!

    DIY Subwoofers - General Discussion
    Hi fellas, Got a box design with a first port resonance is 122Hz. I have read several topics on here itself about this issue, but have not come across a definitive "this is the rule of thumb you should go by" or a final value. Those were a few years back, and would rather not resurrect an old...

    I have a limited budget of $500 and it was suggested to me that the HT-S8400 would be the best fit. The TV that I have is the Samsung 6350 which has a nice USB interface where I can plug a USB hdd and play divx, etc. video files. I am wondering whether the USB port on the HT-S8400 will play...

    I have just built some bass reflex cabinets for a pair of Tannoy Monitor Gold HPD 315s. They are loosely based on designs discussed on the Hilberlink Tannoy, and are roughly 150 litres in volume with 2 100mm diameter, 100mm long ports. (As apparently recommended by Alex Garner of Tannoy) I am...
