DIY- Home Theater Update Denon AVR X3700H and Klipsch R 12SW Unboxing 

I'm in the process of buiding a 5.1.2 Dolby Atmos system, I have a Klipsch R-120SWi Wireless Subwoofer, Klipsch R-41M Bookshelf Home Speakers, Klipsch RC42IIBL Center Speaker, and old Pioneer Height speakers and Sony rears with a Pioneer VSX935 7.2 Channel Network AV Receiver. Vewing on a TCL 65" QLED 4k tv. My center channel speaker comes in tomorrow so I'm excited!

You Made the Unboxing the Klipsch Subwoofer to difficult. All you have to do is open the top, fold them back out of the way and leaving the styrofoam in place, roll it upside down on the floor and lift the box off. Pull the plastic bag down around the sides and then roll the sub upright on it's rubber feet and the pull the bag off. It's Much easier. P.S. I just purchased 2 of these up at Costco for $149.99 each. Great deal.

I think the best height speakers I've heard emotive

I purchased 2 of the Klipsch R-12SW from Costco for $149.99 each on 03/24/2021. Here we go. First off this Sub-woofer sounds decent. After listening to this at moderate volume for 5 days I decided to run some test. But first I run a Sub-woofer Sine Wave Break-in on youtube just to be sure it was broke in. After that, I setup my mini dsp UMIK-1 and using the latest version of REW/Room EQ Wizard to begin my measurements. I tried this in multiple locations and got pretty much the same results. I had these hooked up on my Denon AVR-2807 Receivers LFE output, crossover set at 250Hz and the Klipsch R-12SW crossover set all the way up to LFE. These measured -3db at 40Hz where below this, these fall off a cliff and are down 10db at 30Hz. There is a +3db hump from 50 to 70 Hz and the down -3db at 90Hz where the sub-woofer continues to roll off up to 250Hz. I also stuffed the ports with Acousta Stuff damping material, this actually made the performance slightly better at the bottom at the same time eliminating the Port Chuffing. The Green line on the Frequency response graph is port plugged the Red is not. I then decided to pull out the woofer and measure the power output into a 200 watt 4 ohm Dummy Load Resistor. 16 volts=64 watts was clean. 17 volts is where the peaks of the wave form were getting jagged and got worse up to 20 volts, just past 20 volts it wold drop back to 18 Volts Measured output was 20 volts max which into a 4ohm load is 100 watts. I believe the amplifier has a built in limiter as I could not get the peaks of the wave form to flatten out indicating clipping, they just got very jagged as I turned it up past 16 volts. 20 volts +100 watts was MAX! I returned these to Costco 03/03/2021. I really wanted these to work out but I just can't get over the fact that these did not come close to performing to their advertised specifications. I am very disappointed in Klipsch. I will never trust their advertised Specifications again. Consumers should be able to make educated decisions on what the manufactures advertise. It is getting more and more not to be the case. I have seen so many positive reviews on these Klipsch R-12SW and that is what I based my decision to purchase these. I am the only person I know of whom actually went through the process of testing and literally taking these apart to do actual measurements. I hope that this helps others to make a more informed decision. Good Day.

Why does it need an external amp for an additional two height speakers while it has 4 height outputs in the back? I am confused.

How do you connect the klipsch subwoofer to the denon receiver? The subwoofer isn’t connecting and having trouble figuring it out

How do you plug that subwoofer to the receiver? It has 2 connector to 2 connectors and the receiver have 1 hole for the subwoofer.

Hi mate! Tell me please what kind of subwoofer I need for this amplifier? Active for passive? I'm looking for Bose Module 700. Cheers,

I might have to settle for something cheap for now, as my old Sony is dying, but this level of a Denon is what I'm after... I think the way I will add amplification later to get all 11 channels will be to amplify the front stage... L,R,C. Those seem like they'd free up the most power to subtly all the heights and surrounds off of the receiver unit. Not sure if my space needs more than 5.1.2, but hey...I will add speakers and try it, probably won't need a second sub... when I add too many I can pass them along to a kid and stop adding...lol How do you like that avr and sub after some use ?

Dude, its $149.00 at Costco right now.

Hey bro what cable do you use to connect your subwoofers

Hello very good presentation i have the Denon X2700H I'm working on getting a subwoofer polk signature now i know what to get when i upgrade by the way nice Last Name there was a mention about a Yamaha well i have the yamaha rx-v6a need a bigger Display screen amber orange 🍊. But anyway Happy with the Denon yes and D.I.Y. Home theater in the bedroom .

You can add power amplifier to this

Hi there! would you know if the klipsch R-120SW would be ok to use with a pioneer VSX-934

👍🏾👍🏾👍🏾

Will the Denon support a 7.2.4 set up without a separate amp?

I bought my sub at Costco. I bought it for a little over $200.00. Later, I got refunded for the price difference ($150.00). Btw, is your main speaker is a f300?

Hello bro .is it true ..this model the back panel will be warm while music or movie playing is normal..

That 105 watts is only 2 channels driven.

😏😏😏 ... Yeah ... open from the bottom and pull box upwards if possible on the big items ...

Why don't they just make the remote for the unit Bluetooth

this amp doesnt do 11.2.4 its only 11.2 output so would be 7.2.4. count the pre outs.

Get the PS5 instead. The 2.1 works only currently with the PS5. The new Xbox does not currently work with this receiver.
