No sweat! Unless you were to compress the transients by turning it way up too high, but I reckon you're much more sensible than me

Graham, is there any limit to line arrays with the Proprius?
For example, if I had 16 of the same driver per channel and each driver has 8 Ohm impedance and I wire a 4x4 series-parallel arrangement on each side, would things still sound good?

Just reporting back on my friend trying out my proprius amps with his Kef refs.
As Graham suggested, no sweat. Those big output caps kept everything nicely in control.

Sorry I missed this post. It would work, but I cannot comment on the sound you'd get as it would depend on multiple factors of the proposed design.

In terms of impedance, it would be fine.
In terms of inductance, I don't know as I don't understand the physics of inductors/back EMF for series/parallel combinations. I have four pairs of CHP-90 drivers that I could try a 2x2 series-parallel on each side but it would probably sound worse overall than a single driver per side, especially when you start considering phase shifts and comb effects at different listening positions. Keeping it simple is probably best.

In series add the inductances together so two identical drivers gives double. In parallel 1/L = 1/L1 + 1/L2. So 4 in series/parallel have same inductance as one driver. No harm to the amp or drivers, just sacrificing two or four cardboard boxes...
Are you experimenting or looking for a particular change in sound from using multiple drivers, Ash? A vertical line array would reduce vertical dispersion and give a higher sound image, albeit with interference patterns as you note. Usually multiple drivers are for more power handling, coil heating and lower cone excursion. Comb filtering would be a problem at higher frequencies unless you crossover to a single driver. With two drivers In series on a panel/open baffle you could have a capacitor connected across one of the drivers so its output rolls off? |
