The Official Power Sound Audio Subwoofer Discussion Thread

You guys will need to wear ear plugs once the higher dB are introduced.. lol.
 
:rofl:

Well... at least you have the kids enthused and onboard. My home is similar to your (minus having the kids enthusiastically involved). :T

It's part of the "badge of honor" of being an enthusiast, right?

I know that scene in Interstellar well... and I have to be honest... I think you're shorting yourself. You need to get another one and have dual S7201s in your theater. Not only will you lay claim to some of the best bass on the planet, you'll also have ridiculous amounts of street cred (your ownership has already boosted your street cred to insane levels... but just imagine would two would get you!!)...:devil::devil:

I started the project with the first S7201. Now maybe we can crowd fund the other! :justdontknow: I'd be willing to take REW to the next level and post formal reviews and measurements!

My wife stays downstairs in the family room most of the time. Now that the S7201 is shaking the ENTIRE house, she can't escape the bass any longer. :hush:

@Todd Anderson Any recommendations for video storage? I'd love to take video but uploading to YouTube generally gets the audio removed to the copyright.

Hmmm... I bet if you upload to YouTube without mentioning a film titles in text, you'll probably be able to have it stick. Other than that, not sure.

I'd put good money on a bet that if you came up with a creative story, you could crowdsource funds to get another one of those insane subs into your hands.

Promise a video of the move in process... interviews with your wife, kids, and neighbors... it could be so entertaining that a few hundred people would be willing to chip in enough coin!
 
How about a few movie scenes with insane audio (Interstellar comes to mind)... take some video of the sub cranking the bass?
 
Just watched Life at -12 dB MV. OH MY GOODNESS. Tactile response doesn't accurately describe this sub.
 
Yes. Time to get a UMIK-1 and get REW rolling.

Have you checked to see if your foundation is cracked??
 
Made a slight modification to my S7201.

@climber07, when you get into REW and seeing what is going on in the room for real, you are going to hit a whole new level that is several levels above now.

Accurate bass seems not as fun as bombast at first, though. Get it dialed in, live with it for a bit and you will understand this juxtaposition. I have two settings on my pre/pro, the "fun" setting for showing off and the "accurate" one for serious listening.

Best of luck, room measurement is a game changer!
 
These video show the S7201's power and driver excursion. The audio gets massively clipped on the camcorder. Nothing but pure, smooth, undistorted bass is audible to the ears.

Oh my. Do not...I repeat...Do NOT send that link to your homeowner's insurance. Hide the kids. Hide the pets!!!!!
 
wow.. I am speechless. wow.
 
Climber, did you draw those yourself in a CAD program?

I'm curious about the reasoning behind the varied shape of internal openings between chambers... @Tom V.

I used Sketchup. It's a free 3D drawing program. I used the overall actual measurements when designing "my" version of the S7201, but free-handed some of the holes, drivers, etc. The bottom baffle openings are different shape/size due to the amp cutout.

Here is the actual CAD drawing pic that Jim posted:

I'm still amazed at how powerful it is. The extension is crazy low and clean which causes the how to shake even when there is no audible output from the sub. This subwoofer also dismisses the debate over tactile response in ported versus sealed subs. I feel like I have transducers installed in all of my furniture. You can feel the bass hits in your entire body. I watched Terminator Genysis and was blown away by the absolutely violent output the S7201 is capable of. Tom and Jim have updated the Power Sound Audio site with more specs on the entire line-up of subwoofers. They listed the output specs for the S7201 and it only serves to validate the observations that I have made. Even running the subwoofer AVR trim 8 dB hotter that Audyssey's initial setting and with DEQ enabled, I am unable to push this subwoofer to its limits. MASSIVE amounts of headroom in even the most demanding movies and music.


S7201 Frequency Response
The frequency response graph shows how the subwoofer will sound for a given input frequency or tone. Accurate reproduction of the source material is achieved with a flat frequency response as shown in the graph.

S7201 Compression
The compression graph indicates how the output of the subwoofer changes as the input signal increases.

S7201 Output

16Hz - 25Hz: 124.1 dB
31Hz - 50Hz: 137.3 dB
63Hz - 100Hz: 142.4 dB
16Hz - 100Hz: 137.2 dB

The S7201 output numbers are acquired by using the Consumer Technology Association (CTA)™ Standard, ANSI/CTA-2010-B - Standard Method of Measurement for Subwoofers, formerly known as CEA-2010
