For the size they do, I do not see the speaker equivalent (If the 4311 but more difficult and adnicher Magnat Ribbon with ... but I prefried my 4312 ..). I use it with different amps: Rotel, Harman, Proton, Hafler .. marier.je speaker rather easy to use it for listening to proximity .. (but even when nickel is far .. hi, hi,. ).. (This notice is for passive 4312a monitor speakers ..)

SOUNDS

Medium and adjustments excellent, very precise and sharp

OVERALL OPINION

No regrets, I hope to keep them very very long time they have already more than 10 years and no date has ppins
