Each cabinet consists of 2-5 inch mineral filled polycone woofers with a 14.6 ounce magnet and 1-3 inch tuned chamber cloth dome dynamic tweeter offering a frequency response of 48Hz to 20kHz. These cabinets have a unique rear bass port producing more low end than most sub systems. The mid range in the TA-1P is what sets them apart from any other near-field. Absolutely the best imaging and clarity in the mids anyone has ever heard. The patented crossover design took two years to develop, but our engineers are now satisfied. You will hear why it was worth the wait. The power handling capability is rated at 165 watts into 4 ohms. All rear panel connectors are gold plated .
