Question: Can I use this speaker system, on a 5.1 receiver, without the subwoofer?
Document: I paired this system with a new Onkyo receiver to replace my old Sony and KHL 5.1 system, and at first I was like "meh"... it was "loud enough" (more than enough for my wife) and "okay" sounding but I was not blown away. That's before I setup the whole system in its final spot and ran room correction on the receiver. After all final setup, I can confidently report that this speaker system is AWESOME sounding.
I researched a long time to find a good surround system to replace my old set. The Energy Take 5.1 gets the top online reviews, but I'm a tightwad so I always look for the "next best," "almost-as-good but cheaper" alternative without going all the way down to the lowest price no-name item.
Let me start by saying that I couldn't be happier with these speakers. I did my homework when it was time to take my 6 year old HK SAT-TS2 5.1 system off the wall and make the next step toward turning my living room into a true cinema. Although I have the 6.1 capable Sony receiver and Blueray player (AKA PS3), I decided to stick with a 5.1 system due to the size limitation of my living room (13x16).
Great sound for the price! Sub is very good and satellites are as well. If you need a new 5.1 system this one is a great value.
A few days ago, I finished the wiring in my house to run all 5 speakers (center and 4 satellites). To give you some info on the full system, I am using the Onkyo TX-NR626 receiver to run these speakers. I used Monoprice 14 AWG CL2 rated wires as this is all running under my house, up walls, and into the attic. As a piece of advice here, do your research if you are a first timer wiring it yourself.
I recently purchased this speaker system, and I have been very pleased with the sound from these speakers. I was unsure if the smaller speakers (compared to the 6100) would have enough power to rock the basement, but these speakers sound awesome. The subwoofer really puts out thumping bass, and I just have it turned up half the way. I paired these with the onkyo RC160, and the results are spectacular. The glossy finish looks cool, but is a dust magnet.
I have read good reviews of other buyers and that shaped my decision to buy this speaker system. However, when I bought and installed this system I was rather disappointed with the quality of sound from satellites. My full range JVC speakers (supposedly lower end) produced much richer sound. Sub did make a difference but could not compensate for the dullness of sound coming from the satellites. Center speaker is not bad. I have Yamaha RX-V663 receiver and receiver has been proven to produce excellent sound with other speakers.
I had my home wired for 7.1 and these look great mounted on the walls and ceiling. Love the clear crisp sound of JBL. The bass is also very responsive. I would highly recommend this product. . I am using this with the new Onkyo 7.2 receiver and a new smart TV. Just like you are at the movies!
We just have this system set up, paired with Denon AVR 787 receiver and Monster cables. Not sure how much cable adds to it, but definitely a good receiver is a must for this speaker system to playback perfectly. The sound is pheonomonal. The sound is deep and rich, with layers and details. It is not overtaking the movie if the movie is not loaded with sound effects. We have tested with Movies: Shrek, Chicago, Matrix, Nemo. Each one of them is played very nicely.
I hooked these speakers up to a pioneer vx812 receiver and at first I thought i was listening to a clock radio. They sounded horrible!! But then i realized that i had to recalibrate everything and had not hooked up the subwoofer correctly. Once I dialed everything  in and set up the sub correctly, I couldnt believe my ears. I paid $239 for these on ebay! The first thing i did was put in the Italian Job and watched some  action scenes.
Answer: Yes they all hook up separately.
