What’s Old is New Again

The projected price range is $60-70,000.00. The DD66000 has two 15-inch Aquaplas coated woofers. JBL first used Aquaplas in the 1980’s as a laminate […]

Impedance tells you how much current […]

A hi-fidelity amplifier usually has a frequency response of 20 Hz to 20,000 Hz within approximately one dB. The human ear can normally detect audio frequencies […]

We reused the original polypropylene dustcap, but we can replace with a larger one if preferred. This is just one of the many different model of Time Window Speakers we […]
Under Powering Can Cause Speaker Damage
Any speaker can be damaged with too much power. Low Power Can Damage all speakers, but especially High Frequency Units. A loudspeaker system capable of handling 100 watts should have a high frequency unit capable of handling 10 watts. If the high frequency unit is rated at 20 watts there should be a 100% safety factor. Using an lower powered […]
