My experience adding subwoofers to 2 channel


My Kappa 9 speakers are rated to 29hz and they sound pretty good in my 18x24 room...powered by McIntosh mc1.25 amps...l was looking for another layer of bass to enhance the sound..my first experiment l took my SVS pb16 ultras from my theater room and tried them first...it sounded terrible,didn't blend well..couldn't hear a difference until you turned in up then it rattled the room apart........my final experiment worked..l used 4 Velodyne minivee subwoofers(1000 watt rms class D sealed 8 in.) and after hours of calibration l hit it......lve got the bass response that exeeded my expectations. ....l should have done this along time ago....can anybody tell me of another subwoofer that may work even better?

I would really like to hear  SVS ultra-16 and the New SB 3000 you mentioned.

Blending a single sub or a pair with 2 channel system does make all the difference in the world.

Pretty cool you had a store till 2008 !

We have had many years relationship with our REL rep (was with Magico at one point),

and he shared the REL G1 Mark II’s idea with us , since REL’s specialty if u will, is Sub-bass with 2 channel systems. But perhaps the S Series would be your choice. The G1’s are 5500 each, and we have 2 stacks of 3 shown in the photo gallery. Amazing. The Wilson Alexx speakers are the left n rights. Even the T7i’s I have played with our M7900 that we took as trade-in, and it sounds amazing with the $1000 each x 2 sub base.

But the G1 MarkII’s sound Absolutely incredible sound when you use the 3 in what they call an array stack of 3.

But that may be more extreme than you desire. But they many levels of Sub Bass for 2 channel. And their speak-on connector system with connecting the red & yellow wires to the + side of one speaker and the black to the ground terminal on said speaker. And then do the same for other side.

It was fun setting the different frequency for reach, and then going in to experiment with phase.  Very easy to work with.

Here is our high end listening room (the photo of the G1’s is in the slideshow at bottom of page, sorry, I took the photos w iphone, but the REL stacks of 3 you can see behind the Wilson Alexx speakers. In the top of page photo u will see JL Audio f212’s but those are now in the back of the room used for 5.1 only. The G1’s are for 2 channel and have high level connection, and then for 5.1 listening, we then use LFE:

I use the T5i with my little NAD 3020 office system with a couple of MartinLogan Motion 2’s and it sounds great. :)

Were u talking to Vinny or Me Larry?

I posted the theater link where we have the Wilson Alexx speakers.  But no price. They are $109 K/pair. Except the link lead to the page that priced out the system.  
My boss and former roomate from school owns the showroom, and yes, the Wilson Alexx speakers are certainly worth every penny for the sound.

If someone has the money, and can also have a dedicated, full blown treated room as good as the custom listening room that Robert Harley shared in an article in an issue or two ago, then yes you can totally hear it.  It is really enjoyable to just have folks come in for a demo in all 3 listening rooms, saving the "Transporter" room for last.

I enjoy MartinLogan ESL's (2500/pr) , I enjoy PSB Imagine B speakes (1300/pair), I have MartinLogan Motion 2's in my office with a REL T5i, which sounds great.  You just shift gears when you listen to a pair of Wilson Alexx with D'Agostino Progression mono blocs.

I love listening to Vinyl in there, and then comparing it it to streaming from Tidal, using Roon, thru the Vivaldi DAC and dCS Network Bridge. Usually the Vinyl has greater detail (Brinkmann Bardo turntable w Audio Research Phono 3 preamp), but many times a solid MQA Master recording gives the Vinyl a run for it's money, almost :)
