@j_andrews Keeping the crossover of the sub as low as possible makes it easier to integrate. If its got output above 80Hz it can draw attention to itself. At 80Hz the waveform is 14 feet long. So below that point, bass is entirely ambient in the room before your ears can even know what the bass note is. For this reason the bass can be mono.
I ran a single powered sub with the Fritz Carbon 7s at the recent AXPONA show. The sub was a Golden Ear X, using dual 8" drivers and I used it for the bottom octave only. I didn’t roll off the Carbon 7s.
Since its a powered sub, I set its controls on the rear panel so that the crossover was at the lowest point, 45Hz. I figured the Carbon 7s were good to that frequency!
Then it was a matter of setting the volume control. That took a bit more work, since a lot of recordings don’t have much information below 40Hz. But I had a few on hand. Even still it took me a day to get the setting right, so it wasn’t until the middle of the 2nd day that I had it dialed to my satisfaction. Once that was done you really couldn't tell it was running until it was shut off.
I angled the sub so its output bounced at an angle off of the wall behind it. I found this got me more evenly distributed bass throughout the room.
I use this same technique at home with my Carbon 6s. As long as you don’t play the system super loud the Fritzs can handle not being crossed over. You’re just playing them as a regular speaker.
So its not a big project!
