Dunlavy SC IVA X-over resistor values

Shadorne good read,

When I went external with my Dunalavy SC4's crossovers I hard mounted all the components on 2024 1/4 inch aluminum plate. This material has a high percentage of copper content and is vibrationaly reactive in a good way. All resistors were Vishay metal film and were built 10 up as a bridge type so as these low powered super sounding resistors would handle the wattage. Of all the components swapped out these made for the single largest increase in fidelity. The cabinets themselves were sealed internally with Cascade Audio paste, a latex based product that is drawn into and seals the wood pores. This is not a damping material for it drys like concrete. This material made a huge difference in soundstage size shape and detail.. All fasteners were of brass. The finished out crossovers weighed seventy pounds each with their 10 runs each of driver cable. The primo finishing touch was the improvement made when these external crossovers were placed upon Sistrum SP101's. Resonance to ground control! Tom

Shadorne, The second speaker system I ever owned was Tympani 3a's tri-amped. Very complex system to get my arms around. I was only 22 then and the imaging imbalances in my room at that time drove me nuts. The room was large and so were those panels all the complexity and variables were way ahead of my audio encylopedia at that point in time. Every system since then has been bi-amped, supplemented with subs and electronic crossovers including the Dunlavys. This of course brings about other issues namely phase shift at the crossover point. I can now measure and compensate for these phase induced suckouts in frequency. Tom

And even yet when these speakers are properly coupled within their own cabinet and to the room cabinet that surrounds them they truly become three dimensional and much less critical to placement. Ya just got to venture out and do it. Tom
