Beringer DCX 2496. How to sum channels A and B low frequencies to sub woofer? When using a single subwoofer as I am, isn't it better to have both the left-hand and right-hand low frequencies going to the single subwoofer? Please correct me if I am wrong. At the moment only the right hand...

Is it possible to lock the frequencies, to which REW applies filters? My Yamaha's PEQ only has the ability to adjust certain fixed frequencies...

The Spectrum and RTA graphs in the RTA Window don't show any data below ~15.75 Hz. Is it possible for this to be extended lower with a few more octaves? Here is why I am asking: I'm able to route movies directly through REW using my MOTU 1248 AVB mixing panel. I used an 80 hz crossover with a...

Hi everyone, Are there specific locations beside the listening position that should be measured? It makes sense to measure the listening position, but would make it difficult to calibrate the room if no other locations are measured, right? If so, where should I specifically measure? Is there a...

A friend of mine came over last night and we got into a little discussion about speakers... Here is what started it: My friend has listened 2 my setup several times, and then went home, and listened to his Yamaha NS1000 Studio Monitors. He has found that when he listens to the same 2 songs on...

While a REW newbie, I've been making measurements and some progress using EQ. But I am stymied by the fact that REW seems to insist on choosing the frequencies for filters. I have a NAD C390DD all-digital amp (no analog inputs) that includes a rudimentary room equalization capability. It has 6...

Greetings to all, after buying some bass traps and redoing my measurements I have some questions and also would love to get some suggestions. First I would like to know what should I do about the very low frequencies (20 - 55 Hz range). How to treat them? Would I be able to treat them too...

I'm planning to do a multi-subwoofer IB install. Unless my calculations are incorrect, I believe all room modes will be below 50Hz or so. The room dimensions are 15.5x24x9 feet. However, the long side is cut to about 20 feet due to the stairwell and the only 24 feet long area is a 4x4 foot area...

Hi, I bought the T748 which has 2 Zone included. After running automatic calibration, different speaker settings, different subwoofer settings and positions turning on and off the EQ option of the Receiver and checking different settings I can't get to listen to mid range frequencies like some...

Over the past several months, I have been using REW5.01Beta17 to sweep and measure distortion of amplifiers, crossovers, and other electronic components. REW is a terrific program for doing Amplitude/Phase and Distortion measurements! I am using an EMU-404 (24-bit 48-kHz external soundcard)...

Hi can someone please comment on these graphs and questions. I have noticed that the upper frequencies are lacking and wondering which calibration file to use. The 90% file graphs don't look as bad. 1. With the upper frequencies especially 3khz > between the Left & Right and Both graphs the...

I have been messing with the sms-1 with my klipsch sw310 to see how it works before I start messing with the DIY subs. I can get a test sound with the auto EQ but when I go into manual there is no sound. I type 12345 to get to the main sound screen, same place as the auto EQ test sounds but...

For the longest time, I have had a pulsing in my speakers and I couldn't quite figure it out but it seems to be related to infrasonic frequencies, regardless of any crossover in place. If I'm playing anything on the computer that has content 20hz or under, there is a high pitched pulsing which...

Hello, I live in Mexico and Im building a HT for my family, it is a dedicated room 100% movies. Room dimensions are 11m long 7m wide 2.41m heigth. All surfaces are poured concrete. I will build 1 side wall of drywall to avoid some columns as well as a back wall same drywall. Final dimensions...

Ok basically i have a pair of 6X9 speakers and i bought an enclosure for them off ebay, about .31 cubic feet in size. Now, although their response is largely increased, the lower frequencies are not that good. How do you go about designing an enclosure to get better bass? I'm currently studying...

Have an onkyo 7.1 receiver that's 100 watts per channel. I have boss double cubes for my rear surround speakers, what frequency should I have them at? My receiver is capable of 80 hz 250 hz, 280 hz and higher.

Hi to all : several firms make tractrix horns for 2-way systems ( image 1). The tractrix 110 (horns.pl) can be driven with CD like the Monacor DT-400. But it is suitable for drivers up to 4.5 inches. What does this mean ? I haven t found drivers larger than 2 inches. Could a fullrange 4.5...

Hi Chaps, I have a question to ask.... As you or most off you may be aware I am making two subs with 3 frequency tunes. Tomorrow I will be setting them up and re running Audyssey. From memory I ran Audyssey first and tweaked if needed be with the BFD (although I have a flat response so the...
