Speaker Buying Guide

  • 20-300W recommended amplifier power: Ensures robust and controlled audio that is crisp and clear.
  • Dual 6-1/2" aluminum cone woofers: Along with a 5-1/2" aluminum cone mid-frequency driver and 1" x 1.4" Folded Motion tweeter with 5.25" x 1.75" diaphragm, offer a complete range of sounds.
  • Proprietary Vojtko™ crossovers networks: Designed in such a way that all drivers are kept within their optimal frequency range and balanced with one another.
  • Low-mounted woofers minimize floor bounce: This floorstanding speaker uses 2.5-way designs that feature woofers positioned low in the cabinet and close to the floor and delivers a flat, balanced response through the bass and midrange regions.
  • Custom five-way bi-wire toolless binding posts: Assure a stable connection while accommodating a wide range of connection options.
  • Modern design with luxurious finish: The solid cabinet, designed to eliminate fidelity robbing vibrations, is constructed from 0.7" MDF with 1.2" thick front baffles.
  • 40Hz - 25kHz frequency response (±3dB): Ensures a wide range of accurately reproduced sounds.
  • 92dB sensitivity: Delivers crisp, robust audio.
  • 4-ohm nominal impedance: Allows efficient conduction of power through the speaker. Compatible with 4-, 6-, or 8-ohm rated amplifiers.

Q: Is a subwoofer needed with these speakers?

A: Hello. Thank you for your question and your interest in our products. This can be subjective and also come down to the individual. Subwoofers can not only add to the bass frequencies that the speakers can't hit but, the bass signals can be redirected to the subwoofer, thus enhancing your speakers' efficiency. So adding a subwoofer isn't just about more bass. With a great sub, the system's dynamics rock harder, and soundstage depth and spaciousness improve. So it's not something we would consider a need, but it can dramatically enhance the overall sound of your system. We hope this information helps, and please let us know if you have any other questions. Thank you for your support of our company and for considering us for your future purchase.

Q: What is the RMS watts of the speakers at each Ohm?

A: Hello. Thank you for your question and we hope all is well. The speakers are 4 Ohms Compatible with 4, 6, or 8 Ohm rated amplifiers. We typically recommend an amplifier power of 20—300 watts per channel. As impedance is a dynamic and constantly changing number, the exact power output from an amplifier at any given moment will vary. Luckily the power handling of the speaker always remains the same regardless of its impedance at the time. So it really depends on the amp being used as the speakers power handling does not vary with impedance, only your amplifier's power output varies with impedance. We hope this helps and thanks again for your question. We appreciate your interest in our products and your support.
