Any specific setting recommendations for F15HP and Sierra Towers.

[aiverson]

I recently received my F15 and just followed the basic setup procedure. I was wondering if anyone had any experience with this setup and if they had any settings or tips they recommended. Which crossover level, damping etc.?

Thanks

What is your setup and usage(Just towers and 1 sub, etc.?)? Associated equipment(Receiver, preamp, amp?)?

I have 2 systems...... 1 for home theater and 1 for music. The HT system has dual Rythmik LV12F ported subs and the music setup has dual F12 sealed subs. I used ported for HT due to the large, open room.

The HT is run by a Denon X3300 AVR with Audyssey XT32. Crossover at 80hz to all speakers, though I have in-wall/in-ceiling Klipsch for that. Set to Low extension (Not the same controls as your sub or my F12's).

My Sealed F12's are crossed at 80hz and so are my Sierra-2EX's. I use a preamp and amp setup with a MiniDSP 2x4HD to integrate, EQ, and crossover the subs. I did room measurements with REW and a UMIK-1 and then setup an EQ curve in REW, which then was exported to a file and then imported into the MiniDSP. Damping is set to high and extension at 14hz.

That's the extreme way to do it! Your usage and system will sort of dictate your course of action.

I had same questions on your setup/usage as Ed.

That said, I, too, have two setups (HT & Music) although use 2xE15's for both.

For HT, I run the sub out from my MRX720 to miniDSP 10x10, then from miniDSP to LFE in on the Rythmiks. Rumble filter is on (I listen to alot of vinyl), 14 Hz extension, High Damping. For LFE in, as you probably know, cross-over, phase, low pass are inactive. I also have limiter on (so I can use Auto On with the 1 E15 that has the PEQ amp -- I added the 2nd sub later so it has the XLR amp)

For music, I run L/R line out from my Rogue RP5 into the same miniDSP 10x10 then from miniDSP to Line In on the Rythmiks. Same rumble filter, extension, and damping as for HT. Cross-over is at 80, Phase is at 10 o'clock, Low pass at 80/24. I could set the crossovers/filters in the miniDSP but currently just use the controls on the sub amps.

Sub EQ is done in the miniDSP using REW for both HT & Music.

Maybe one of these days I will rerun REW and also deploy Anthem ARC for HT. Likely after I get my AVM70.

My setup is primarily geared for two channel. I have the towers running through a Schiit Freya + preamp, mono Aegirs amps. So no EQ or receiver control in my setup. Using line in from Freya to the F15HP.

Ok, then. Looks like Ed and I have many of the same settings for music. I'd start with the music settings I posted above and see how it sounds to you.

You may need to tweak the phase a bit to integrate the subs/mains in your room. You could also try a lower cross-over (maybe 60 or 70) and different low pass filter settings to see what sounds best to you.

In addition to those great recommendations, I'll add this......

Curtis had a great suggestion how to dial in the phase. While playing a test tone that is the same frequency as the crossover point, with mains and sub playing, run a sound pressure level meter (Rat Shack, REW w/UMIK-1, etc) at the listening position while turning the phase dial and leave the dial at the point that produces the highest SPL. Another person to help would be ideal!

Adding distance is same as adjusting phase
