You need to get load resistors of the same value of the load you will be using.

Well, first you need a load resistor for the output of the amp. Digikey has some 16 ohm, 50 watt resistors which you can put in parallel to get an 8 ohm 100 watt resistor. Here is the page for the resistor: The resistors need to be mounted to a heatsink or large metal plate - the larger the...

The best test for how well a speaker handles transients is either a single cycle pulse wave, or a square wave, both of which have a leading edge slope which is infinitely steep. Most of the energy in a cannon shot is in the bass, which by definition is a slow event. Plus the cannon shots have...

If you're referring to me, I don't use planars because they don't have the dynamic capabilities of horns (not even close), they don't have the efficiency to allow SET type amplification, and they don't have the controlled dispersion of a horn system. Plus, as noted before, they run out of steam...

Planar speakers will launch a larger (and coherent) wavefront, in-line with their larger size compared to the smaller speaker. They will also because of that project a better sense of scale than a smaller speaker. They probably aren't more popular because, like other large speakers, they have to...

For awhile many years ago before I built my current room, I had my Altec A-7-500s in a bedroom that was about 12" square. I also had some smaller speakers in the same room. The A-7-500s definitely sounded like the larger speaker, in fact it sounded like the entire wall behind them was radiating...

We can sense the size of a room by the reverberation patterns, and this mechanism is probably no different than our ability to tell the relative size of an object by our ears. I've done some binaural headphone tests where I could also tell the relative size of objects; there's one catch though...

The is something in human physiology where we can sense how "large" something is by the way the sound impinges on our ears (not just ear drums, but the pinna which defines the head related transfer function, or how we sense things like direction - including height - and size), and it doesn't...

If he is married to, or has a girlfriend who he thinks can beat the shit out of him, then ,yes.

By request, I'm porting over a thread I started from the S&V forum. I wish there was a way to capture the entire thread and bring it here, but hopefully we can start a discussion again on the subject of small verses large speakers, and specifically, how important is a sense of scale in Hi-Fi...

I think it all boils down to: Acoustic treatments = Ugly In The Wife's Living Room And given that the majority of American men are totally pussy whipped......well......no acoustic treatments......

By the way, it was also common practice on popular music recordings to record the backing orchestra on two of the tracks as stereo, and record the vocal on the third track; a primitive form of multitrack recording. Some relatively recent rereleases of vintage recordings use this third channel to...

For many years in the 1950s, 1/2" 3 track tape machines were the norm (Ampex 300-3). For stereo releases the engineers simply mixed the center into both the left and right channels at a level of -3dB, which would yield even volume for the center as the left and right. The RCA recordings you have...

Oh.... I actually have an early version of the program, fooled around with it a bit, but never did anything with it.

What program is it?

That's actually extremely good response.

You should still have the "0dB" point be your reference voltage or reference dB level. Without the reference, nobody can tell how far down the noise is.

The Y axis numerical legend is kind of goofy in the program you're using. Usually "0dB" is set to be the reference level for the test such as having it equal 1 volt, with the noise so many dBs below that, like this:

The soundcards in desktop computers generally aren't all that great, but yours seems to be particularly screwed up, or there is something wrong with the measurement. In any event, if you're really concerned about audio quality on your PC, you should upgrade your soundcard. I use the ASUS Xonar...

Great idea!!!!!
