Masterplant Attenuator A2XR 200W 16 ohm

If you want reactivity at all levels then you should check out this one. The sound and feel will be rawer and more open. This is all dependent on the amp and speaker used but you should instantly hear a treble rise and a low frequency hump that is usually flattened out with a standard attenuator. Some describe this as the sound is coming alive which is as good of a description as any. Reactive at all levels
