Chops' Modest System...

Recommended Posts

UncleMeat you’re correct that running a tube amp without a load is bad, but for most solid state amps it is no problem.  The channel with no load is putting out just enough power to run the meter.

 

Especially with a single sub, changing the location will change the standing waves in the room, so experimentation is the way to go.

And the really nice thing about running the system through the dbx Venu 360 is that I have total control over phase for the sub (all channels actually). Not only do you have the option of keeping the phase "Normal" or "Inverted", you can also adjust it infinitely between 0 to 180 degrees. Since I've got the mains and sub crossed over at 62 Hz, I can (and did) run a test tone via the internal tone generator in the dbx at 62 Hz and gradually slid the phase back and forth between 0 and 180. With my eyes closed and listening carefully, I ended up at -100 degrees. I then checked with an SPL app on my phone and ended up at the same -100 degrees. All done in the listening seat via laptop control.

It sounds like you got it dialed in good.  Another way you can try is to run your 62 Hz test tone, and invert the phase on the sub.  You can probably do that with the dbx, but you can also just swap the wires on the sub (if it is driven from an external amp).  Then move the phase to make the SPL minimum.  When you switch it back, it should be flat through the crossover.

Thank you Owen, and welcome!

Thanks to loner_t for sending it to me. His babies are once again together, the way they belong. Thank you LT!

 

After reconfiguring the dbx for true dual mono subwoofer output (instead of stereo), tweaking phase and gain multiple times, I've got things dialed in pretty good. According to the RTA on the dbx, I've got a pretty darn flat response across the board, solid all the way down to 20Hz. One sub I have the Phase switch at 0 and the phase knob around 90*. The other one the Phase switch is at 180* as well as the phase knob around 270*. 

 

I know it doesn't look like it, but the speakers and subs are 1/4 way out into the room. The room is small, roughly 12 x 13.

You are welcome.

 

Glad to see them put to good use in a loving home. If you decide to play Skyfall (James Bond) at night, just turn it down a wee-bit during the explosion and chopper scenes, otherwise your neighbors may object. =D=

Well, I wuz going to watch Skyfall tonight, but after doing some browsing around on HBO Now, I stumbled across Deepwater Horizon. I've been meaning to watch this movie for some time now, and read somewhere that it was a good one for some strong bass content. Long story short, it did not disappoint. With one of the first main explosions, these two subs were pressurizing the room like crazy. I played that part back a couple times, the last of which I watched the woofers... A solid inch an a half easily of excursion! Just a little more than half of what they are capable of (2.5" Xmax). I can't imagine ever reaching that as these little beasts are plenty loud enough in this room.

 

Very strong, very deep, very clean bass, and very impressed!

 

In other words.... DAMN!

Hi Chops,

What kind of speaker  Cables are you running in the back of those speakers to the amp. Looks very thick and serious. I just rewired my with 12 gauge,  but I really like how  clean  it looks with the hook up.I'm not sure if I could afford what you have going there,

Looks very nice..

Hello David,

 

Those cables are Audioquest CV-8 with 72 volt DBS battery packs. They are equivalent to 12 awg. They're a little bit on the stiff side, but not bad. This is a 10' pair that I bought off of Travis here on the forum for I think $220. You can typically find them online for around $300+/-. To me, they are definitely worth the money. 

 

Thank you sir for the kind words!

Now running my 10 year old AV123 X-Statik loudspeakers, half sealed, half open baffle. I rather label them as GR-Research however as Danny Richie is the brains behind these speakers and because the schmuck that ran AV123 was into some really shady business which ultimately landed his big butt in prison for a while. 

 

Anywho, these have fully upgraded crossovers as well as No-Rez lined inside. Both made big improvements! I forgot how awesome these things sound. I only used them about 3 weeks after the upgrades when I got the Martin Logan's. 

 

The grills will come off soon.

Im in the middle of building a pair of those......X-Statik......right now.

They await sanding day......which happens to be today...

 

Kits go for $375 US.....from GR Research.

Over the years I've built a lot of Dannys stuff....V-1, Super V, "H" open baffle servo subs(refinishing them as well)

 

Dont have a clue what Im gonna do with them.....maybe lliving room.

Really?! Very cool!

 

Yeah, the kits that Danny put together for these are quite a bit less than what I originally paid for them. 2 years ago, I paid more than half of their original cost just on caps, resistors and No-Rez to upgrade them. Well worth the money and time I might add. 

 

These X-Statik's are great sounding speakers. Basically blows away everything else I own including the NHT's and Martin Logan's! The closest competitors are the Genesis Physics II's believe it or not. 

 

Those V-1's and Super V's are supposed to be pretty spectacular. I don't know how the X-Statik's will stack up to them. I wouldn't be surprised if the X-Statik's will give them a run for their money though from about 100 Hz on up. 

 

I was going to build my own version of the V-1 years ago, even bought four of the Eminence 12" neodymium drivers from Danny for the H-frames, but never started the project. In fact, I still have those drivers sitting in the original shipping box... Never opened!  I can't remember the model number, but would love to do something with them. I even bought the servo amps to go along with them, but I sold them about a year later. Again, never opened.

The V series are VERY nice......I had them many years.

The servo subs on the bottom are absolutely the best subs I have ever heard period.

When it was time to move on from the Vs I sold only the P-Audio co-ax and kept the

servos. They currently being refinished as well.....I kept the round bottom of my Super Vs

and are retrofitting as I type. They will be paired with my PAP Trio TB, they match perfectly.

 

I've also  built a lot of Selah Audio.....Rick Craig...designs.

My HT sytem is all Selah.

I use The Symmetrica arrays for fronts and the 128 (sedona) arrays for rears.

The center is a Sardonyx and I flank the system with 2 of Ricks Duo 12" sealed subs

Good to hear you hold the X-Statiks in high regard......I've been wanting to hear them for a long while.

As you get older, and your memory isn't what it used to be, you may not remember just where things came from.

I come across boxes and open them to find things I had completely forgot I owned... and have no idea when I purchased them.

Shortly after my last post, I came across your posts and galleries on AudioCircle. I thought your name sounded familiar. LOL

 

I think you're going to love the X-Statik's once you get them completed.

I was trying to post this video here on the forum, but it won't let me. I thought I was able to do it before, maybe with the old forum server?

 

Anyway, this is a link to it. Amps peaking around 20 watts and roughly 96 dB. Crystal clear and the kitties enjoy it! The video is just over 6 minutes long, a full song, and a very good song at that.

BTW, the two kitties in that video... The white one (Bailey) is totally deaf, she was born that way as I have learned that a lot of pure white cats are. The other one on the floor, he's Puzz. We got him from my grandmother when she passed back in 2007. Puzz is 27 years old!

Made a little upgrade to the system today, though not for audio, but video. A Hisense 50" 4K UHD (50H6D) TV. It was the last one in stock, and only $300! I couldn't resist. That little 32" 720p TV was killing my eyes. Man, the image on this thing is amazing! Excellent blacks, zero motion blur, razor sharp, perfect color. This TV would be an excellent buy at $1k!

 

Okay, enough TV talk. 😁
