Not really impressed with all those obscure brand names I’ve presented till now? Hold your horses, now. I know most of those designs are pretty down to earth and don’t really add much to the artistic impression. The truth is manufacturers are not that interested in looks as much as in performance. Avalon Acoustics has another opinion, though. Take a look at their Sentinel Active Reference System.

Avalon claims that Sentinel features all the latest groundbreaking technologies in high accuracy transducer development. In this sense, outstanding improvements were brought to diaphragm materials, three dimensional magnetic field modeling, low-noise circuitry, resonance control, and temporal coherence.

As far as design goes, Sentinel already earned prestigious awards like the “Component of the Year” and the “Edge of the Art Award." Among Sentinel’s highlights you’d certainly notice the unique facet structure for proper polar response control. The cabinet construction uses Avalon’s proprietary multiple aperiodically damped internal chambers, coupled with out inert golden-section baffle design. The floor stand system also integrates dedicated subwoofer amplifiers with built-in active crossovers.

Need some tech specs? You got them:
- Frequency response: 16Hz to 100kHz
- Sensitivity: 88 dB
- Nominal impedance: 4 ohms
- Recommended amplification: 100 to 1000 watts
- Drivers: Diamond Diaphragm Tweeter, 3.5" Ceramic Dome Midrange, 9" Nomex-Kevlar Composite Cone Woofer, 2x 13" Nomex-Kevlar Composite Cone
- Subwoofers Dimensions: 1753(H) x 432(W) x 940(D) mm
- Weight: 415 kg

Don’t ask me about the price of these behemoths. Seriously, you don’t want to know. No, I’m not telling! OK… $ 84,995. Happy now?
