Decision made!!! Going Dual....

Grimster74 · June 2020

I'll be moving onto Dual SVS PB16-Ultras!!! I'll be placing my order sometime this week. As much as I loved the thought of going with Dual JTR captivators, just can't justify the price at the moment. Not only that, if I place a order for the dual SVS's I'll save $200. Can't wait to see the difference over the dual SVS PB12-Plus/2's that I'm currently using, according to SVS it should be quite an improvement. Guess we will see in the next couple of weeks. Has anyone else made such a move that you can share your experience, I'd love to hear about it.

I went from a single PB13-Ultra to Dual SB4000's and the difference was astounding... I do not miss the ported monstrosity and placement issues that come with it and the dual SB4000's give a greater experience overall.

I hope you have help moving them....

You are gonna love it, especially when dialed into your rig/room/mains. While I have not heard that exact sub in stereo, I do have the Rythmik F-25's hooked up in stereo and flanking the mains. When I did this, I had not realized just how much or the lower registers were also in stereo.

Running dual subs also seems to even out some room deficiencies as well.

One suggestion if you have the room and if they are wired in stereo.....place both subs on some solid stands that have the center of the woofer at your tweeter height and toe them in to be pointed straight at you.

I did this and the visceral impact, realism, sound stage, cohesion, imaging and performance height (where the performers were up on the stage) were all improved in words that would be very difficult for me to describe. After experiencing this, I will never go back to stereo subs on the floor. Just a friendly suggestion to try out if you have the room.

Good point Tom. I think this is why you see companies like REL using arrays of stacked subs.

I only have two currently but would like to give an additional two a try. I was very surprised at how the two changed the overall texture of my current setup.

Congrats, I look forward to hearing what your impressions are.
Are you trading the Plus/2s in?

If not, where do you live again???

sgmsmg · June 2020

You can save a little more if you watch the inventory in the SVS outlet. Usually minor if any cosmetic defects.

I'm sure I'll have one if not both up for sale very soon, Virginia by the way, LOL!!

DaveHo · June 2020

I've got a single plus/2. Can't imagine duals. That said I'd take a hard look at Rythmik if you haven't before you commit to the SVS.

Hey Tom what freq. do you cross your subs over at?

treitz3 · June 2020

Hmmm, that is a loaded question. The F-25's have a plethora of adjustments, each one affecting the others and how it reacts to the room, to the mains and to the overall presentation as to the end result as to what hits your ears.

Normally, I am between 32 and as high as 48, which I think is too high in my room but where it sits at depends on so many other factors within the control panel. It was set at 42 ever since I readjusted it for the addition of the Canary. Only this past weekend have I started futz'n around again to see if I could improve the sound.

The limiter is usually off, PEQ on, gain at 0, bandwidth at 3:00 and frequency at 32-35. The subwoofer toggles are at AVR/12, rumble filter off while the LP rig is currently unconnected. The extension filter toggles are at 14 for frequency with high damping. The delay is set at 0, non LFE crossover overridden by EQ (but usually set at 38) with the volume set at 11:15.

As you can see, it's not just where I set the frequency. I tune them all by ear and these settings are what I have found to be my "starting point" based upon my room, how they respond and blend with the mains and how the entire system presents itself when sitting in the listening position.

Self admitted, these are not the easiest subs to dial in and given the location within the room, it takes a while just to do one simple adjustment and evaluate what changes it just made to the end result as to what hits your ears.

For example, if you make a change in the damping, you may want to make changes in the frequency, gain and volume. You do it on one and then you have to do it to the other and in my room, where they are located? This is not an easy task.

So, to answer your question, that's a loaded question and though I have a starting point for the room/rig/mains and their settings? It is still work in progress until I am 100% confident I absolutely nailed it.

Do you use a room analysis software to assist with dialing it in, and confirming the response that you're getting? A lot of those knobs aren't clearly marked with white lines and/or detents so it seems like a tricky process.

treitz3 · June 2020

No and it is a tricky process. I had a Velodyne SMS-1 before and after "optimizing" it, I ended up dialing that one in by ear as well to achieve the best end result.

Measurements are overrated and can't tell you how the perception of imaging is changed, it can't offer any information on height information or other locational cues of the reproductive effort. Measurements can't tell you how the perception of space or the size of venue is observed/perceived to the listener. They are and can be a very useful tool for those who are not intimately familiar with frequencies, nodes and the like and how they affect the end result as to what hits your ears but along my audio journey, that it. It's a guide. A useful one but one that has its limits.

I built my system guided by my ear, tuned it by ear, adjusted everything by ear and while I may not have achieved perfection (I never will), I damned sure have exceeded excellence.

Getting back on topic, the dual subs helped me to achieve where I am at now in my audio journey and the OP should be very pleased.

Velodyne was my introduction to what truly deep bass sounded like.

treitz3 · June 2020

My apologies to the OP for all of the off topic posts. The Velodyne SMS-1 in combination with a VMPS Larger with upgrades was my introduction to true lower registers and an outstanding (or rather, seamless) blend with regards to the mains to the subs and both to the room. It taught me many things and was an invaluable learning experience.

The dual Rythmik F-25's have surpassed that previous combo.

Going duals is the best way to capture the depth of your sound system. I was looking at the SVS 3000 subs and at the last minute, I went with the SB16 subs. Ive had them for almost 2 months and I do enjoy the bass as I went 2 yrs without it as my old system was good but had issues. I also wondered how it would sound with just one sub, so I would turn one off and it was lacking depth. With 2 subs, its effortless and I really feel at home when the subs tremble and make the room come alive. The bass is astonishing despite turning the volume down so it sounds more natural rather than obnoxious. I did get to experience an SVS 3000 that my sister bought at the same time. She placed it behind the couch and that was enjoyable from a single sub. I told her just think what 2 would do?

Good plan going with two. I visited my friends house. He has the SB-16. That thing is a monster and could pressurize the room very well. But I could not stop noticing where it was. With him having just one I could tell exactly where it was located during listening. Now he uses it for mostly theater/movies but other than the SPL I thought two would integrate better than the single.

Usually indicative of a polarity mismatch on the mains, mine blends seamlessly but it used to call out its location the same way. That is until I dialed in the polarity and phase.
But still would like to have another.
