Hi all,
I’m now officially a PS Audio ower of a classic power port, Detect power conditioner, Stellar Gain Cell preamp and Stellar S300 power amplifier. My question is the best way to connect a subwoofer. I do agree with Paul using high level speaker connections. I have a Triad Omni 8 subwoofer that has speaker level connections. Can I use the connections second channel of S300 using both red and black terminals?
Yes!
Aren’t both speaker terminals on the S300 hot with the black terminal not being a ground? In addition the amp in the Triad is also a Class D amp so both it’s speaker level terminals could also be hot,
That’s what I thought. So I should just connect the Red terminals?
To my knowledge, this is really only an issue on rel subs who don’t have a balanced input for their speaker level input. Most subs have no issues with floating bridge amplifiers.
I thought as mentioned in the S300 manual. Thank you. I just wanted to make sure.
While Chris may be correct, it comes down to whether or not you want to chance it and it be an expensive mistake. In a secondary setup I am running a pair of RSL Speedwoofers with Class D amps connected speaker level to a pair of Starkrimson 25 GaN Class D amps. In both sets of amps both terminals are hot. What I am doing and it works with no damage to either sets of amps nor any hum is as follows. Connect the Red terminals as normal but not the Black terminals. Use a spare piece of wire stripped to bare wire on both ends. Connect the bare ends to a chassis screw on both ends. With the subs the screws that hold the amp to the cabinet should be long enough to back out to attach the wire on that end. If the screws on the S300 are not then order thumbscrews in the right thread size to replace one of the S300 chassis screws to make the attachment on that side. This is what I ordered from Amazon but you need to find out what size the S300 chassis screws are.
Aluminum would not be my first choice to make a connection to a copper wire. Its not a junction that holds up well to electricity.
If aluminum causes you a problem in this application then there are plenty of alternative choices on Amazon once you know the size and length needed.
