Spec Real-Sound Processor RSP-901EX Loudspeaker Filters

Wojciech Pacula has posted a review of the Spec Real-Sound Processor RSP-901EX loudspeaker filters (€990/pair) at High Fidelity. His conclusions:

“It works in a similar way with accessories like RSP-901EX: we know how they work, what’s the scientific background, and yet hearing them work still comes as a surprise. It’s even more so because they change an already good performance into even better, more refined, more dynamic, smoother and yet offering even more information in the top end and lower bass.”
