Technical Questions


Q. What size amplifier should I use to drive the Cubes?

A. All the Cube models represent 8 ohm loads and are very efficient. Virtually any power amplifier or receiver regardless of wattage rating may be used to power your Cubes. We generally recommend that you purchase the highest wattage amplifier or receiver your budget allows to facilitate added headroom (power reserves). This helps deal with low frequency transients (bursts of sound that require the amplifier to output more instantaneous power to accurately reproduce these sounds).

Q. How do the Cubes' reproduce low bass with only 4 1/2 inch drivers?

A. By using multiples of these drivers, the effective cone surface area is additively increased. If you place multiple drivers in a vented enclosure and boost the extreme low frequencies with signal processing, you end up with an overachieving "bookshelf" size loudspeaker.

Q. Do these speakers need special placement? For home or studio?

A. Yes. The Cubes four front facing drivers were specifically placed for a tight radiation pattern to increase imaging and minimize and on-axis phase shift. The optimal placement for the "Cubes" is to toe them in so you are directly facing the front baffle, with the center of the speaker at ear level. Also, the enclosures are vented with a rear firing port. This arrangement allows you to "adjust" the amount of bass energy in your room by placing the "Cubes" different distances from walls, floor and ceiling. Basically, the closer to a reflective surface, more bass, further from one, less bass. The choice is yours.

Q. Will the Cubes work with home theater? And how do you hook up the EQC-1 active equalizer?

A. Absolutely! Because of their dynamic range and "amplifier friendly" impedance, they make excellent home theater speakers. Most A/V receivers today incorporate a PRE-OUT/ MAIN-IN set of connectors around back of the units. The receivers’ PRE-OUT and MAIN-IN connectors interface with the EQC-1's LINE-IN and LINE-OUT connectors respectively. For those of you who are using separate components, the EQC-1 will be the last piece of equipment wired in just before your amplifier/receiver. Simply put, program source outputs (surround processor, pre-amp, mixing board, etc...) to EQC-1 LINE-IN. Then EQC-1 LINE-OUT goes to amplifier/receiver inputs.

Q. The Cubes are smaller in size compared to other similarly priced speakers. Can they compete in sound quality?

A. Absolutely! One cannot measure qualitative differences quantitatively. Materials used in construction, some not even seen with the naked eye, can affect the sound quality as well as the cost of a loudspeaker. A high end loudspeaker design strives for accuracy and listening enjoyment as long term goals, no matter how big or small the speaker size.

Warranty Questions

Q. How long is your warranty and what does it cover?

A. The Cubes come with a 5 year limited warranty that covers parts and labor for manufacturing defects or component failure which occurs under normal use.

Q. What do I do if I have a problem?

A. Call us and we'll issue an RA (return authorization) number. Ship the unit back to us UPS ground with insurance in the original factory boxes and packing material (these provide the best protection against damage). We'll repair the unit and ship it back to you UPS ground with insurance at our cost.

Q. What if I buy the Cubes, and decide after 30 days I don't like them?

A. Call us and we'll issue an RA (return authorization) number. Box'em up and ship'em back. As soon as we receive them and verify (right away) they're in the same shape as we shipped them originally, you'll be refunded the full amount of purchase.

Purchasing Questions

Q. What advantages do I have buying factory direct?

A. We're saving you at least $700 off the suggested retail price that you'd otherwise pay in dealer markup! We're also the best possible source for technical information and support, and nobody understands the product or its intended uses better than the manufacturer. Also, no sales tax on out of state purchases!
