That is correct. Music sounds great with damping set to high with bass coming through as clean and articulate. Movies have more impact when set to low. I listen to both equally (50/50).

I have my two F12SEs set to High, even for Movies. In Low I get complaints from neighbors upstairs. mad.gif

These are choices between max output capacity (2 ports, low dampening, high frequency) and max low frequency extension (1 port, high dampening, low frequency). They all do it in different ways, so any combination could be your favorite. It's a lot of options to understand, but that's better than having to buy a new sub if you decide you want something different.

A bus and a small child for reference. Looks like shipping hurt the outside of the boxes' feelings a little bit but I'm sure all is well inside. Can't wait to set them up in a month. Happy Thanksgiving.

Yes it really is a lot to understand esspecially with the 1-2 port option.

So far I enjoy the 14hz , hi, 1port and I also really enjoy 14hz 2port med damp. Should give me flat to about 18hz.

I might have a bit of a low frequency null becuase I cant hear\feel much of a diffrence in the 12vs 18 hz extension. Only very slightly can i FEEL the diffrence in the 12hz ex mode.

Anyone else use 2 port mode?

As I said before I have plenty of output in 1 port mode but I seem to enjoy the 2 port mode listed above...

Please give feedback on impressions and settings!!

What movie or material were you watching or listening? If the content does not have down low frequency, you won't feel the sound with 1 port mode.

Grenade scene wwz

What settings do u like for movies?
post #11889 of 15114
In do like the 1 port 14hz hi/med the best so far. Just saying I do enjoy the 2 port 14hz hi/med as well
post #11890 of 15114
So everyone wanted a more in-depth review of my up and running dual F25 setup. New update time after a couple more movies:

EVEN MORE AWESOME THAN PREVIOUSLY REPORTED.

How's that?

Honestly, I haven't really play with those settings much but stick with what Brian's recommendation for movie (14/low). When I have time, I will play with these settings.
Are you running your dual fv15hps with your lv12r?

I have to fv15hp and run both ports open due the large space (roughly 6000 cubic feet when taking into account all open adjacent spaces). I have settled on med for both movies and music. I am so used to med that I can hear what I am missing with low. I have a harder time hearing the difference between med and high. I can hear it but only when critically listening so I have settled on med. If I ever bought a second sub I would probably still run both subs with both ports open due to large space I have to pressurize. If I move homes and can have a dedicated space then I would definitely switch to one port.
post #11893 of 15114
^^ can you explain what's missing switching to low from med? Thanks.
post #11894 of 15114
When you switch from hi->med->low, you get a steeper filter slope. This does a few things:
1) It reduces output in the lowest frequencies.
2) Reducing low frequency output saves amp and driver extension headroom, so you get more power higher up.
3) The steeper slope can cause ringing (smearing of detail) in the lowest octave.
4) The steeper slope can affect phase more, although Audyssey (especially XT & XT32) supposedly corrects for this.

You ability to hear the difference depends on content and the room. I couldn't hear the difference in my room until I had multiple subs split across the front and back of the room, since I was sitting in a null. If you can't hear the difference, you sacrifice nothing for more power.
Some rooms need the extra power.
Taste is also a factor.

While it's helpful to hear about other people's experiences, it won't necessarily apply to you.
It's also helpful to experiment with the frequency and port options.

^^Thanks for a detail explanation.

Was wondering if I should put my LV12R on an isolation pad being that I have hardwood floors?

No wife....lol

I actually have tiny furniture sliders under each leg, just in case I need to move it around.

Is it worth the $70 for decoupling? Thanks Beee Man
post #11899 of 15114
The smearing of detail in lower octaves is my experience. The sound is still way more detailed than any sub I have owned before even in low. But now that I have experienced and adjusted to cleaner bass I can hear the difference. I have a hard time listening to music in the car now... need some rhythmic car audio solutions :-)

Do you have a wood subfloor or concrete? If you have a wood subfloor, try a stomp test on the floor and see how sturdy the sub-floor is. Normally, you want to place the sub on a location with strong foundation to minimize vibration. Stomp test can help you locate that. The decoupler is most effect when the sub-floor is less than ideal. If you already have concrete subfloor, all subdue does is raise the height of the subwoofer.
post #11905 of 15114
Yup tvs next. I almost bought one this black friday but I have spent quiet a bit of money in the last couple weeks (fv15hp, christmas shopoing, new dslr camera for wife etc..) plus I'm going to be working away from home for almost 6 months so I wouldn't even be able to use it.

I would also like a new reciver. Somethiing that will eq my subs. That way I can hook up this reciver downstairs to my pro cinema 600 setup

The floor (2nd floor) that the sub is on is just hardwood (bamboo), no concrete. My 1st floor is concrete, but no subs there.

Then stomp test is good. A good subwoofer placement should also take structural rigidity into consideration. Along the wall that you can place subwoofer, maybe there is one or two locations that you have supporting walls. Stomp test can tell the difference.

BTW, the sub does come with rubber feet (ideal for hard surface floor) and I assume you are using those.

Out of curiosity, how available are the FV15HPs?

Then Denon X4000 or Marantz SR7008 are you best choices. I have a Marantz SR7008 and XT32 with SubEQ HT did an amazing job with my two F12SEs.
