Purchased this item today. What would be the ideal lpf and subsonic filter settings in a .85cubicft sealed enclosure?

Your better off geting a custom enclosure built. If its a prefab box your not really getting anything out of it. But you usually set the subsonic to half of the tuning of the box. Lof is usually 60 to 80hz is fine.

Check fuses first. Then look at you high pass, full range and your low pass switch. Sensitivity also. Also your level min/max settings. If all else fails, contact planet audio.... they are great over there about walking you through installs.

Not sure, my system is very quiet after that first fill up. Maybe it's defective, try calling customer service.

306 will be enough for it. Bought 306 here before but exchanged mine to my friends eheim filter because of too much noise. If you can stand for rattling noise, I'd love to recommend you to purchase 306.

Probably a bit much for those. Think infinity recommends 1.5 ported or .75 cubes sealed per sub.

Indeed, 80 wpc should suffice, although it will be best to have the 901's speaker suspension foam replaced to ensure vivid ambient sound reproduction at low volume output. I did the foam replacement about ten years ago on my 901 IVs, and those are performing admirably.Cheers,KJ BleusMadison, WI USAkjbleus@gmail.com

Closing the port will not solve the problem. The box dimensions are different and a sealed closure should be between 1.2-1.5 cu ft. Also I doubt you will have a proper seal on the box. Any air escape will change the sound. I've been very impressed with the set up but that's MHO.

For a sealed enclosure like for 1.25cu.ft and 1.5cu.ft for ported. I personally have mine in this box, http://www.amazon.com/gp/aw/d/B004X63LQ2 gives some good clean bass while still delivering strong bass.

The sub Box you need is a box with a air volume of .80You can make any Design of box as long as it has a air volume of .80 or as close to that as possible I have two of these subs and my air volume for each box is .78 wich is really close to it and it won't make a difference for tht little bit off from .80

In the manual it states that if Channels 3/4 are switched to LP (Low Pass) that the HP (High Pass) adjustment will turn into a subsonic filter adjustment instead. I am emailing back and forth with Hifonics technical support to try and figure out if that is for the 5th channel. Why would they have a subsonic on the 3/4 channel only? Im not sure, why wouldnt they have a subsonic for the subwoofer channel that needs it? Im not sure. Seems like someone forgot something when designing the amp.

Yeah, for sure a large sealed enclosure due to the high QTS (open baffle) parameters of in wall speakers. Ported would result in many trial and error tunings with midbass peaks. Try it out though, no difference between wall cavity and an enclosure to the speaker itself. Without T/S specs this will be a gamble, try around 1-1.5 (larger yields deeper bass extension roll off but less accuracy in bass tones) cube feet enclosure to mimic a wall cavity, heavy stuffing. Have fun.

I bought a 90 hz low pass filter and just ran the positive and negative through the filter and hooked it up to the positive and negative of the sub. It filters out all of the mids and highs and sounds great. Then I just hooked up my other speakers to the remaining channels on the amp. Hope this helps

Thank you so much for the information. I bought some 58mm filters and an adapter and have held them in front. I will look for some 37mm so I can do your workaround. Thank you for the information.

I have mine set at 60,0" phase and ~100hz on bypass and I've had no problems. What amp are you using to drive it? I listen to lots of heavy bass music and can easily drive myself out of the room if I crank my amp so the question is--? what do you want to do the heavy lifting. The amp or the sub?

It actually works pretty good in a sealed enclosure. I bought an 8 inch sealed bass tube enclosure just to test out all the hype ive heard about this sub and I must say you definitely wont be disappointed
