  • I recently upgraded my active x-over LPF to a PRV DSP 2.4X for biamping <100hz. 4 separate outputs & many options - slope, phase, freq, delay, gain, PEQ. I set the initial setup close to the old x-over, then adjusted. Room corrections w/PEQ are impressive! More defined bass, better coherency, cleaner upper bass & lower mids. Wish I'd done this sooner.

    I love your rig and your living room looks very warm and cozy.
    What are the speakers?

    Speakers are a pair of Sterling Acoustics Acumen IIs. Made by my small company around 1990. Focal woofer and midbass in a transmission line, and a modified Seas H400 tweeter. :cool:

    Recent upgrades getting it done!
    1. Added a Linn LK140 woofer amp <65hz
    2. Adjusted the felt baffle treatment on the speakers. Easy & effective
    3. Added 2 Tung Sol ECC803s to the preamp.
    4. Added wool felt panels to the back of the speakers to help absorb wall reflections
