Well, my roll off is natural since I have auto eq off.

As long as the high-end doesn't sound too toned downed to you, you're golden.

It's sounds pretty sweet. For the $260 I spent on my LCRs ($390 retail), I'm very satisfied. And they're not overwhelmed by my Rythmik sub.

I'm currently giving high extension/damping a try for at least a few days to see if I like it. Do I need to bother with generating a new set of filters based on the high extension/damping frequency response with no EQ applied? Or does this current frequency response (see attached) look suitable (hc1, mid based filters)?

High ext/damping alters the FR below 30Hz; it doesn't just control dampening. So, you should apply new filters or at least run YPAO again.

80Hz seems like a bit of a stretch for most mids, so I would give 90-100Hz a listen before pulling the trigger. Forget 120Hz !

If it's not too much trouble, what is the minimum EQ you can apply that simply gets rid of the 2 peaks and the dip in between them (without any net boost when all filters are summed)? I want to preserve as much of the existing FR as possible (minus the 2 peaks and dip in between them).

Removing all filters in the MiniDSP makes YPAO set the sub trim a whopping 8dB lower. So, I guess that is the price to pay for aggressive cutting of huge peaks.

For info purposes, here's an overlay of the response differences between low/mid/high without any EQ applied. However, since sub placement and gain knob position did vary (and measures were weeks apart amongst other variables), they are not an exact match past 100Hz to about 200Hz.

Nothing more can be done with your current placement. Either change the location or change the room or enjoy what you have right now till the time you move your setup in a more acoustically friendly room.

I basically removed the first filter to preserve the high damping characteristics and then tweaked the dip filter to avoid any boost (0dB gain at 60Hz). Do you think this should sound good?

I appreciate all the help you gave with the 5 sets of filters I currently have. At this point, I'd like to learn how to manually create filters myself and perhaps get suggestions from as many AVS members as possible. I think I'll start a new thread in the Audio Theory and Setup section so I can learn how to fish as opposed to asking for fish.


(I really just want to tweak things to my personal preferences at this point and since no one knows exactly what I prefer other than myself, learning how to create filters and what kinds of FR curves to target should be the next step for me.)

What about the auto EQ that REW creates?

I can't seem to get it to target the kind of house curve I want (or even close for that matter)... perhaps the house curve feature in the preferences window might be the answer...

I must have done something right, because right now watching previews before the start of my BD movie sounds very tactile and punchy for high damping. Not too weak like in the past. Getting rid of that 30Hz filter must be why.

Do subs sound best at 80Hz and under only (crossovers)?

Can I ask why you are taking measurements and doing eq from 1m vs your MLP or is the distance just coincidence?

1M sweep is measurement quality in REW, not distance between mic and sub.


Mic is in MLP (exactly)

I gave higher crossovers a try with the LV12R and after a day...

Went back to 80Hz crossover and simply cranked up sw trim to compensate. It seems each 10Hz step from 120Hz to 80Hz resulted in cleaner, clearer, more tight and precise bass. 120Hz and 110Hz were quite bad sounding, whereas 100Hz and 90Hz were a lot better but still noticeably off.

That's coz the sub ends up playing upper harmonics as well above the fundamental xo frequency. The higher you set the xo; the higher the upper harmonics seep into sub response, which sounds awful. That's the reason wall linings are used inside the sub to attenuate upper harmonics should you decide to use higher xo. But that can only do so much.

One alternative is to cascade two LPFs i.e. engage LPF on AVR and sub as well. The net effect of two LPF will cut upper harmonics and you may be able to get away with higher xo setting.

But what's up with Rythmik subs can go as high as 200Hz? Is it ok to use 200Hz if I have dual subs next to my fronts?

That's too high an xo. I wouldn't do that. Even the weakest and cheapest of bookshelves can play down to 120Hz. With an xo of 120Hz fundamental frequency, the sub would end up playing till 240Hz (2nd harmonic). You can even hear 360Hz (3rd harmonic) if LPF has shallow slope.

Most of the male and some of the female voices will be bloated and directional. Now it is a separate case, if one has trained ears to discern the difference. But I guess mostly would.

In your case, you may get away with it if you place your subs next to mains.

Interesting, so using the 24dB/octave setting on LV12R and/or lower crossover/lpf frequency could allow higher crossovers without sound quality suffering?

Or using the crossover feature in the MiniDSP to apply exactly the lpf I want?

Though I wonder if it's worth the trouble over sticking with 80Hz crossovers...

I'm going to try 24dB/octave lpf slope on the LV12R while sticking with a 80Hz crossover to see if that sounds even better than 12dB/octave on the LV12R. It's only one flip of a switch so easy enough to try. Though I might need to redo the sw distance tweak...

Initial impressions are more articulate but weaker... will do REW measures and sw distance tweak later I'm curious what the sub only measure will look like.

^ looks pretty similar especially when you consider the 12dB/oct measure was with sw trim 2.5dB hot and 24dB/oct measure was with sw trim 4dB hot

@braveheart123 , do you know why my measures look the same between 12 and 24dB per octave on the LV12R? Am I measuring the wrong thing? Because I can definitely hear a difference and since the sw distance remained at 11.2ft between both lpf slopes, the only reason it should sound different is due to the sub's lfp slope setting.
