Default PRV 6MR500-NDY-4 HiPass Setting

So..... where are y'all setting the crossover point on these? Freq response according to PRV is 105-12500 and they recommend using a 275hZ HiPass with a 12dB slope. I've got roughly 140w going to each..... just wondering if I needed to go that high or if I could drop it a little lower?

It is a balancing act between the power and crossover setting. Are you using the amp crossover to set the frequency?? Is there a eq or DSP in play?

The best way would be to play a variety of your favorite songs and adjust the crossover to get the sound you are trying to achieve.

Normally with those speakers I have found between 85 to 105 to be a happy spot depending on the amp

No DSP yet, just using the crossover dial on the amp. Still debating between a few DSP units and trying to decide if/when I wanna throw some 8's inside the bags...... gonna make the decision on the DSP when I decide on the 8's.

I wouldn't run lower than 150, with no idea what your amps crossover is doing. Enjoy the super clean mids it has. I've bottomed these out really hard and I was impressed they didn't die, but now I know where they work great for me.

They certainly do hit hard with good clean power to them. I have mine bridged on a JL XD amp getting 150 each crossed at approx 100
No issues bottoming out and will punch you in the chest

Exactly how they've been running on a few bikes. The remaining two channels have been feeding those DD horns, which don't always fair so well.

I have mine down in my lowers, and when cranked up..... I get a good foot message when I'm propping against the highway pegs(Which is how I ride 90% of the time.... heal on the floorboard, ball of foot on the highway pegs)!

I did some calculations last night after checking the amp gain settings again. I got a handheld oscilloscope in over the weekend to make sure I wasn't getting any clipping at my initial calculation of 23.6v on each channel and found out that I was, so I had to bump the gain down to 22.5v to keep clean signal which means I ended up with 126w going to each speaker instead of the 140w I thought I was sending them. Right now I have them crossed over at ~115dB based on position of **** and my calculations... but I have a DSR1 coming next week that will allow me to dial in specifically what I want.
