I have some free time this week and while I am very happy with my 5b's since doing the x-overs (Solens, Mills, etc) and the RD0's, they still aren't voiced exactly how I'd like them. I'm looking to get close to the same voicing as my wonderful SDA 1C's (sans the SDA part).
These are fused rather than using a polyswitch. The schematic replaced the 2.0 ohm with a 2.7 ohm resistor when using a polyswitch. My guess is the poly adds 0.7 ohms of resistance ????. These originally had 2.7 ohm resistor and I replaced with a 2.0 ohm (not really all that different).
These are not harsh or shrill or edgy, but they are very forward and "in your face" I'd like to tone down the output of the tweeter to have it sound a bit more laid back, like the 1C's. How do I accomplish this w/o completely screwing with the x-over too much?
I have a 2.7 ohm Mills which I was thinking of running in parallel with
the 2.0 ohm already in the signal path of each tweeter. My Ohms law is a bit sketchy, so if I remember, running 2 resistors in parallel *sums* the value, so then the resistance becomes 4.7 ohms. Would it be better to get a single resistor of the correct value?
Will this alone be enough to make the tweeter a bit more laid back in the circuit? What draw backs, if any? Will this even make a difference? Any other ideas? I'm also considering bypassing the Solen cap in the signal path to the tweeter with a Platinum Sonic cap. Maybe this will help, maybe not.
My 1C's are just so much more laid back and effortless. I'm looking to get some of that in my office/computer rig. Bass and mids are great as, well a soundstage, etc. The problem with these older Monitor series is the tweet produces so much of the upper midrange freq as well as the highs so I'm sure that's why these sound so forward.
Any advice is appreciated.
I'm sure perhaps the gear plays a very small part in the sound being on the bright side, but this is a second system and I'm not running out and swapping gear.
