Custom Line Source 9
(CLS-9)

Response Audio is producing the external crossovers for the CLS-9. The sonic signature of the crossover is influenced by the use of some of the most highly regarded passive components currently available in the industry. The use of Mundorf Silver/Gold and high quality reference Teflon capacitors, Mundorf and Goertz foil inductors and Mills non-inductive resistors is just part of what makes up this very special crossover network.

Each crossover employs the circuit design topology created by designer Danny Richie of  GR Research, and employs components that are matched to tolerances within 1% or better. Our crossovers are point to point wired ensuring the simplest and least intrusive signal path. A custom external crossover enclosure houses the crossover and resides between the speaker and amplifier in the circuit path. The link between the crossover and speakers is made via four custom umbilical cords utilizing the patented JPS Labs Alumiloy wire and connection to the speaker and crossovers utilizes professional grade speak-on connectors. Bybee purifiers in this link are available as an additional option.

The passive bass management is handled by a series of switches accessible by the user allowing you to tailor the bass output curve to your specific room in real time.

Each crossover is inserted into a CLS-9 test system and auditioned at Response Audio prior to shipment.

The CLS-9 speaker system is internally wired with the patented JPS Labs AlumiloyTM solid core wiring.

What people are saying about the CLS-9

Here is the bottom line, these speakers are just plain enjoyable to listen to, they do just about everything as right as I could want or imagine.  I find myself thinking of them as exciting, dynamic, detailed, lush, natural and musical.  In short they just sound right. At the price these are selling at, if you’re in the market, not auditioning them could lead to some major regrets later on.  I’m putting my money where my mouth is and placing an order for myself.

The CLS9 is a totally different in presentation, the visual size of the CLS9s is insignificant compared to the auditory scale of the presentation. If you can envision a Imax screen of at least 15' H * 25' wide with its curved aspect that is as close as I can describe the scale of the auditory presentation of the CLS9s- Positively tremedous, a different animal towering above and beyond the size of the speakers. The walls and boundaries are totally obliterated- World Class!

You might not think you need the extra capabilities at the extremes or the huge radiating area of the planar array until you experience the dynamic swings the LSs can do. Even at normal listening levels the increase in microdynamics and eyeblinking cymbal shots are uncanny and an experience even long time listeners can't fathom. Everything comes out of the blackness with an ease an effortlessness. Everything is rich and 3D, bigger than I even thought possible. You owe it to yourself to audition these any way you can. The value for this unique perspective and performance is unmatched. I have not heard anything that does the things the CLS9s do. Well thats all I can say.
