Audax Hifi Loudspeaker Kits

AUDAX SIGNATURE SERIES KITS Over the last 3 years, Audax Loudspeakers has recreated its product line. The new products utilize space age materials including Carbon Fiber, Aerogel, Kevlar and Titanium. The new products look better and perform at a level that is state of the art. To demonstrate this higher quality achievement, Audax asked Vance Dickason, author of The Loudspeaker Design Cookbook, to create kit designs that show the product potential. Madisound is grateful for this serious commitment to the kit builder from Audax. We have built these kits and can recommend them without reservation. Madisound has also created custom Oak cabinets with rounded solid corners and full grills. They are Audiophile kits that can be assembled in a single evening. Signature Series A652 Kit The A651 is a two way design using an Audax HM170Z0 6.5" Aerogel HD-A cone woofer with phase plug and as AW025S3 1" Aluminum dome tweeter with phase diffuser. The enclosure is computer optimized for a vented QB3 type of response yielding an F3 of about 55Hz. This enclosure provides maximum damping for bass detail and produces an output of 100dB, remaining linear down to 40Hz. The crossover is computer optimized (using LEAP 4.51) as a 4th order Linkwitz-Riley type at 3kHz which yields an overall efficiency of 86.5dB. Third order networks couple with the natural rolloff of the drivers to achieve the desired 4th order slope. Signature Series A651 Kit The A652 is a 2-way design using two Audax HM170C0 carbon fiber 6.5" woofers and a TW025M0 1" textile dome tweeter, mounted in the popular D’Apollito configuration with the tweeter placed between the two woofers. This technique produces a smoother vertical frequency response above and below the listening axis. The enclosure is optimized for a modified QB3 type of response yielding an F3 of about 53Hz. This volume provides a well damped group delay profile for bass detail and produces an output of 105dB, remaining linear down to 37Hz. The crossover is computer optimized (using Leap 4.51) as a 4th order Linkwitz-Riley type at 2.8kHz, which yields an overall efficiency of 90dB. The 4th order slopes are achieved by using 3rd order networks and the natural rolloff of the drivers. The response of the speaker is 60Hz - 20kHz +/- 2.2dB with a very flat off axis response. Dimensions: 25" T x 9.25" W x 11.75" D Dimensions: 16.4" T x 9" W x 11.75" D Both the A651 and A652 will perform best when used on stands of about 24" in height. As with any quality 6.5" woofer system, the low-frequency response does not produce much output in the lowest octave between 20Hz and 40Hz. For this reason, this speaker makes an ideal satellite speaker to be used in conjunction with a powered subwoofer, or bi-amped with an electronic crossover, separate amplifier and subwoofer. www.cadaudio.dk

AUDAX SIGNATURE SERIES KITSOver the last 3 years, Audax Loudspeakers has recreated its product line. The new products utilize

space age materials including Carbon Fiber, Aerogel, Kevlar and Titanium. The new products lookbetter and perform at a level that is state of the art.

To demonstrate this higher quality achievement, Audax asked Vance Dickason, author of TheLoudspeaker Design Cookbook, to create kit designs that show the product potential.

Madisound is grateful for this serious commitment to the kit builder from Audax. We have built thesekits and can recommend them without reservation. Madisound has also created custom Oak cabinetswith rounded solid corners and full grills. They are Audiophile kits that can be assembled in a singleevening.

Signature Series A652 Kit

The A651 is a two way design using an Audax HM170Z06.5" Aerogel HD-A cone woofer with phase plug and asAW025S3 1" Aluminum dome tweeter with phase diffuser.The enclosure is computer optimized for a vented QB3 typeof response yielding an F3 of about 55Hz. This enclosureprovides maximum damping for bass detail and producesan output of 100dB, remaining linear down to 40Hz.

The crossover is computer optimized (using LEAP 4.51)as a 4th order Linkwitz-Riley type at 3kHz which yields anoverall efficiency of 86.5dB. Third order networks couplewith the natural rolloff of the drivers to achieve the desired4th order slope.

Signature Series A651 Kit

The A652 is a 2-way design using two Audax HM170C0carbon fiber 6.5" woofers and a TW025M0 1" textile dometweeter, mounted in the popular DApollito configurationwith the tweeter placed between the two woofers. Thistechnique produces a smoother vertical frequencyresponse above and below the listening axis. Theenclosure is optimized for a modified QB3 type of responseyielding an F3 of about 53Hz. This volume provides a welldamped group delay profile for bass detail and produces anoutput of 105dB, remaining linear down to 37Hz.
