One channel drives a pair of MaelstromX-18's in a sealed box, wired for 8 ohms (four 2-ohm voice coils in series).
The other drives a Danley DTS-10 tapped horn, 4 ohms.
The issues are:
1) I just got a MiniDSP EQ to match and smooth the subs' response and apply sub-20 Hz HP filters.
Its output is 1V max, whereas the 4080HZ input sensitivity is 2.25V for max power.
The spec sheet says the 3000's input sensitivity is ~0.8V, so that should take care of that issue.
2) About one time in ten my circuit breaker trips on system powerup; it runs my entire system, including a 9-ch receiver and Buttkicker amp.
Question: Will two IPR 3000's have a significantly lower current inrush then one 4080HZ?
I'm hoping they will because of the absence of a large power xformer and reservoir caps.
Another question:
The sealed sub is much less efficient than the Danley; is it possible to share the load equally among both 3000's by bridging the left channels to drive one sub and the right channels to drive the other?
Speaking of bridging, SickNeedHelp said this:
Did he really mean to say signal ground, which is presumably isolated from chassis ground?SickNeedHelp wrote:How to bridge the 1600 has been covered in prior posts. It's exactly the same procedure for the 3000. Just be sure you understand that what is normally the hot connection of the B channel connector is actually ground (to the chassis) and what is normally ground of the B connector is hot. A+ to B- is the key.
I don't see how what is normally the B+ output can magically become chassis ground by the user changing his wiring choice.
