Some suggest it only sounds good when an adjustable crossover (on the stereo) is used to kill mids going to the sub. Do you agree? Why/Why not?

If the sub or your head doesn't specify a crossover built in them then you should use a crossover. I'd suggest an inline crossover like this http://www.amazon.com/FMOD-Inline-Crossover-Pair-Pass/dp/B00EZXWWHW/ref=sr_1_3?ie=UTF8&qid;=1392864302&sr;=8-3&keywords;=inline+crossover

Not sure - My car audio deck has a Sub Woofer out, but no adjustable cross over frequency, and I don't know what is the cut off frequency. The Kenwood subwoofer has got an adjustable crossover setting (on the wired remote control unit) from 50Hz to 120 Hz.

Now that I've had this speaker for several months, I can say that it is marginal as a subwoofer. It really depends on the equalization of the music you are playing. It has problems in the 200-800 Hz range. I try to keep those frequencies down as much as I can. I used to own a sound and lighting company so I am very picky about how things sound. There are a lot better subwoofers out there but will cost you more money. I will eventually replace this with a separate power amp and subwoofer that is stronger in the low-mid frequencies.

No the crossover is seperate, but my 4 channel amp has a crossover so I just tuned them with that. To be honest if your amp has 1 buying 1 is a waste of money, and there very very loud, mean as hell haha

Right now I have this running to my sub amp. I use the radio for my mains. Just have to adjust the levels to make it sound right.

I know I'm a bit late to the game on answering this question, but I have to keep the "Subwoofer" dial nearly off, otherwise my entire house shakes. What little % I do have them turned on is enough to rattle the desk and the walls -- it's a wonderful sub, and really packs a punch! If it was higher wattage, I might even suggest converting the sub over for car audio, but it just doesn't have enough room to work with for that purpose.

R. Williams - Nope. I've run this sub-woofer for countless hours over the years...sometimes under "unusual" circumstances and often with very high demands...it has operated faultlessly. As I noted earlier, "it'll make you happy". It still brings me a solid "lower-end" sound (and feel, too.). I'm thinking that Matthew Robb's reply is right-on. An ill fitting cable can make for a weak ground. Feedback is another possible cause...NAH...not likely. Hope your annoying "super loud buzzing" is soon ended.abez2.

This device only has two output channels, so some form of separate crossover would need to used from the outputs. I think adding components like that would defeat the purpose of buying a simple stereo amp like this, though. I'm using mine to drive left and right speakers which themselves have separate subwoofers built in to each of them, although there's no crossover circuitry; it's just two sets of wires coming out of each speaker. I put the subwoofer wires into the same amp output holes as the main speaker wires, so I'm not actually getting a discreet sub channel. I'm sure the EQ is way off, but for my purposes and at low volumes, it's not essential.

Im no expert however i would set the sub at 12 on both the power and crossover than tweak the sub with your receiver.also check your setup and use the small or large. the large will send a full response to the front and surrounds.just play with different adjustments and decide what you like. also google a link called subwoofer crawl it is very interesting.i did look @ the polks rm95 and i would set them to small than use the 505 to handle the low end.polks are 95 hrz low end so try you crossover @ 120.

Mainly its for awesome mid range , not for mid bass or anything a sub would play , but it very loud for mid range .. If you have a spl set up , you really should have this up front , sound stage ..... Hope that helpz

Is does not have a crossover, it does have a capacitor which will block lows, but you could use your component speakers crossover instead.

Agree with others--probably just need to adjust your receiver settings or check your sub. My receiver and sub sound great in my room and even outside for gatherings.

They determine the midrange output ( I think more or less bass) I played with mine and didn't really experience a difference. I have mine set in the middle.

Even though your mains go down to 48 hz, the general consensus of audiophiles is to set your cross over around 125 hz. This allows your mains to focus on the higher hz, making them more efficient (it takes much more power for low hz) and allowing the sub to do what it does best.YMMV

The tweeter part of the speakers have built in crossovers, but not the main speaker. You can still damage them if you allow to much bass through them.

I personally haven't added nothing extra to the system and it sounds great. Between the amp and this device, nothing but bass comes thru the subs. Side note I did notice the bass setting on the radio does add/decrease the bass thru the subs. just for tuning purposes.

No, shouldn't be too powerful! You can adjust the crossover frequency and volume of the sub if you think it's dominating.I've read that your Vizio has very good bass (which I'd consider mids) so you should be able to get smooth, balanced sound.Some people on the Vizio Q&A; page are using a sub, and they're happy.

I feel it can. I have 2 and play rock music very loud ( with a pair of JBL L 7's) i have the subs turned up 1/2 way and the crossover is set at 80hz and they have plenty of room to go louder and deeper.

Short answer is yes. The signal goes out of both the high and low outputs together. I tried it. It worked but I realized to get enough volume to the sub to make it sound good, you were distorting the power to the speakers. They were also really drowned out by the sub. My recommendation and what I ended up doing was to get a 4 channel amp, bridging two channels for the sub and using the other two channels for the speakers. With the amp crossovers, you can really dial in the sound and get the best bang out is the sub. Good luck.
