F25

[qwknuf6]

Would a F25 Rythmik sub (sealed dual 15" ) blend with Sierra 2 and a horizon center in a small room , I have a 12 sealed Rythmik in there now and the subwoofer bottoms out on movies , I have it turned down so it won't bottom out , but I wish i had more headroom.

It bottoms out? How loud do you play it in the small room? Is it calibrated hot? Do you have the bottom end eq'd high?

Not calibrated hot , but some movies make the sub bottom out , I had the volume knob @ 1:00 , turned it back to 12:00 but I feel like for movies it will not keep up , it's great for music

Do you have the rumble filter turn on? For movies, the recommended setting is 14hz or 20hz, low damping and rumble filter ON. This will conserve the energy on more audible frequency band.

These days, there are too many movies with overloaded subsonic signals that makes cone move like crazy and yet we hear nothing. One of the common one is the opening scene of edge of tomorrow.

Yes I have the rumble filter on , I have tried all different settings , I even sent it to Jim Salk to see if there was something wrong with the sub but he explained it was just reaching the max movement of the driver , Jim adjusted all the settings for me , I have tried different rooms and equipment , checked the setting in the AVR , movies just tend to max out the 12" subwoofer , I have 15" rythmik and I have never noticed it reaching max travel .
So would the F25 blend with the Sierra 2s and horizon Center ?.I would crossover @ 80HZ.

I have dual F12's and I can't ever see needing more bass even in a very big room like I'm in now. I have them set at 12 o'clock and -9 dB in Audyssey, so they have a lot more room to go. When I turn them up they make the whole house shake during reference level movies. I mean it's intense, it scares the daylights out of people and you can feel your chest moving. I sorta find it difficult to believe that there is such lacking bass with one sub. You may want to buy another one and see if you can even out the room modes that way. It would make more sense that you are just experiencing lackluster subwoofer placement due to room compromises. A second 12" sub would be much cheaper and would be more likely to solve any room mode issues you might be experiencing.

A sub crawl, when in doubt, is always recommended as well. I've read some crazy stories of people getting massive improvements in subwoofer performance after a sub crawl. This assumes that you are able to place the sub in the spot where you find the best sound. Usually that isn't the case, and that's where a second sub can really help out, again if you have space.

What is the size of the entire area that is open to the sub?

[qwknuf6]

Room is sealed , 11X11X9 FEET

Hmmm....the F12 shouldn't even be breaking a sweat with that room size at reference level. Call Rythmik.

I have sent the subwoofer back to Jim Salk , he tested it and gave it a clean bill of health , even adjusted the setting for me , I only have trouble with movies , not music , the driver or cone bottoms out or clips on sudden explosions and such , I play loud but not over the top , below reference I would say
