If we had a marketing department, they would edit everything I write.

We believe your ears should be your guide. Nothing else matters.

We never believed frequency response figures from others. If you put the microphone in exactly the right position, and apply the perfect amount of smoothing, you can make any speaker ‘look’ great.

The following is for the Pinnacle. Accuton Diamond tweeter installed.

Frequency Response; 18Hz – 20KHz +/- 1.2 dB,       16Hz  – 60Khz +/- 3.0 dB

Power Handling;         30Watts – 200Watts

Weight;                          540 Lbs, (270Lbs each channel).

Efficiency;                     93.5 dB

Before we nod our heads with approval, let me tell you a story:

When I was a young man, I went to buy a stereo. At that time THD measurements where the figure of the day. I bought a very nice receiver, with very low THD, and enjoyed my music.

Years later I went to High End Audio in Toronto. Mr. Salvatore sat me down, and I listened to the CounterPoint Sa12 amplifier. I was floored. I had never heard anything like this. Still not very bright, I asked him what the THD was?, he laughed. ‘This amplifier plays music, who cares what the Total Harmonic Distortion is’. I bought it.

THD was no longer a parameter that interested me. Frequency Response figures are equally as meaningless. If I place the microphone in the exact right position, apply the perfect ratio of smoothing, I can get 16Hz – 22Khz +/- 0.2dB. Meaningless. Your listening room can impart +/-6dB swings just by the speaker placement. There are a multitude of high end speakers with fabulous FR figures. How do they ‘sound’. Do they put the performers in the room with you?

Kunlun :     24Hz – 20Khz +/- 1.2dB, 10Watts – 200Watts, 93.5dB efficiency, 260Lbs per pair

Qaidam ;    24Hz – 20Khz +/- 1.4dB, 10Watts – 200Watts, 90.0dB efficiency, 200Lbs per pair

Our speakers have a single goal; make me feel as if I am ‘at’ the venue during recording. On truly spectacular recordings, I am the microphone in front of the singers and the instruments.

An example of why you should never believe or use published frequency response figures: Let’s look at the Accuton Diamond Tweeter. It is one of the best measuring conventional tweeter available. These conclusions where made by independent audiophiles. Now look at the manufacturer’s measurements below.

If you listen to our speakers toed in, then my above response figure’s are wrong. If you listen to the speakers, where your ears are 30 degrees off axis, then we are flat. Depending on where you’re sitting, there will be a 4dB swing, but my above figure says 1.2dB?.

There are a lot of variables for ‘flat’ response. Room response in the base means no speaker is ‘flat’ in the bottom octaves. At audio shows this is even worse: some people are ‘sitting’ in the perfect position, some are almost directly in front of one of the two speakers. Some of the people are standing. With room gain this means some people will hear one thing, while others something different.

Search ‘golden ratio’. This will help with your initial speaker placement.

Have YOU fixed all the ‘first reflections’ in your listening room?. The most important is the space between and behind the speakers. That big window, or the large flat screen TV, will wreak havoc with the sound. The side walls are next. And for gosh sake, get rid of that beautiful glass coffee table right in front of you (or at least cover it with something thick).
