Home Theater

"The soundcard measurement varies by 11 dB between 20Hz and 20kHz, that is much higher than it should be, the measurement may not be valid and should not be used to make a calibration file" I just tried calibrating my external USB soundcard and I got this result. I matched the out/in levels very closely and completed the process correctly. What does this mean and what should I do now? Thanks

:wave:

Hello folks, Here to learn. Hope I can contribute at some point too. Just out together my first home theater and absolutely love it. But already looking for upgrades... What an addictive habit!

I just got into home theater with the wife's approval. We live in a a town house, which is really an apartment, lets not kid ourselves. A home theater and apartment dwelling don't mix well, but I want what I want. My wife and I agreed that we'd wait to build our home theater system until we moved into a house, but when my father in law gave me a set of this speakers for free it was all I could do not to set them up immediately. After scolding said father for encouraging me to start early, the wife coincided and bought the needed devices to get a working system going. I was given a Morel applause system, which apparently is somewhat rare. I replaced the sub with a definitive technology pro sub 800 and since his receiver had no hdmi options I bought a denon 1913. I built the tv stand myself and did not think about a place for my center channel. So my center is not actually center with my tv but it sits right in front of my seat on the couch. So for only $800 out of pocket I have a great system for this small room, even though its pretty entry level stuff. It's an enormous upgrade from the Sony towers in the pic which are now just holding up the morels. This is already addictive. I'm looking for my next upgrade... Looks like I can't post pics yet...

Using some 500 pound triple wall corrugate, fitted with Vifa A10CC-07 (made for M&K) two way drivers and Eminence Alpha 8 (Parts Express) woofers and a simple 3-way crossovers from Parts Express. They sound better than they have any right too. Actually surprisingly good.

There are some speakers I built for my friend Carter. He had the vintage Altec 605B sitting around and wanted to use them. Here is the design I came up with based on the Altec 620 cabinets plans. First I cut up a couple sheets of 3/4" MDF.

I just picked this up today for free. It comes on at first, plays but has pink diagonal lines that seem to pulse in speed and slowly change angle after it is on for a few, then the width of the pink lines thin out. Also, after a few minutes is suddenly turns off, with the blinking green light. If I unplug it and restart it works the same again and repeats the shut down. Am I looking at caps again causing the shut down? What about the diagonal pink lines? thanks for help. JIm

Hello everyone, While I am new to this forum I am not new to audio and home theater. My first audio equipment was from my father who was an engineer/troubleshooter for Electro-Voice back in the 60's and 70's and consisted of Electro-Voice and Gerrard. The first system I bought was in 1981 and consisted of a NAD 3020 receiver, Kef 303.3 speakers, Rega Planer 3 turntable (I think it was a 3), JVC dual cassette deck, and a Sony reel to reel. Things have changed over the years and I now have four systems in my home, three home theater and one 2-channel audio. I started upgrading 3 of the 4 systems last year but have now been bitten by the DIY bug. I am currently building cabinets for two different pairs of bookshelf speakers. If I can ever manage to glue up a square box I will move to the next step :scratch:. My goal is to build a five channel system this fall. Looking forward to exchanging ideas and experiences.

I hope to get some brainstorming from you smarties. Lets get low and loud here... Just pulled the trigger on 2 Ultras. I would really like to put together the optimal vented system with the drivers, enclosures, and the space I'm putting them in. TC Sounds site shows a couple of different vented enclosure sizes spec'd for the Ultras. 6.4 cubes at 20hz and 8 cubes for 15 hz. My current subs fire to the front and vent to the sides. I would like to vent out the front on the new set. Has anyone built a vented Ultra or at least modeled a set? Playing with winISD a bit - 7.8 cubes at 16hz is about as nice as I can make it look with my limited experience. I can make it a bit smoother with 10 cubes and a giant port. As far as I can tell, I get the same exact thing plus 3db with 4000w as opposed to 1900. I believe x-max will happen with more than 3500w per driver with 16hz tuning, but I could be wrong. Here's what I have for LFE: 2 18" LMS Ultra, 2 EP4000, and a Reckhorn B-2 for HPF. The room is 12x22 swiss cheese with doorways, windows, vaulted ceiling. Enclosure has one place to go, under the screen, 7x2x2, 6x2x2 would be best for aesthetics. I am replacing a set that occupied the same space. I am ready to sell the EP4000s and order the fp14000 if that is what I need. I am also wanting to replace the Reckhorn with a more accurate unit with a HPF and EQing. Something from minidsp.com maybe? Here is a 3D rendering that I created in autoCAD for reference ;)
