Home Speaker Asylum

General speaker questions for audio and home theater.

RE: 6 - 7 octaves if you're into low fi...

Operating a driver at frequencies where the wavelength is smaller than the driver's diameter results in frequency combing or destructive interference off axis. This is acoustics 101. If you wanna argue that fundamental point, go read some basic texts on acoustics or talk to the hand.

"The D130 I mentioned is good to well past 6KHz!"

The D130 was a 15 inch driver. The wavelength at 6khz is about 2.25 inches. If one were to cross that driver over to a tweeter anywhere near 6khz, there would be a very narrow dispersion pattern between 1500 hz and the crossover frequency. At the crossover frequency, the dispersion would flare out or as is commonly said in the industry- "bloom". This may be high fidelity to you. To me and the industry professionals I know, it's rubbish. All of the JBL drivers I've ever used were extremely well made, low distortion units. But that doesn't fix a novice's poor design or misuse of a driver.
