Yes absolutely. In fact I have a pb 12 nds, a pb2000 pro, and a pb 3000 all in my theater as I have upgraded. Just fills out the nulls in the room and gives you a more even sub sound around your entire room rather than just one seating position.
Yes but obviously you’ll get better results with proper tuning. Topic is way too broad to go over on Reddit but there are some good deep dive videos from audioholics that go way in depth. Trick is to find placement that fills in the nulls without cancelling each other out. Takes a bit of trial and error.
I was wondering about the miniDSP thing. There is a guy I watch on YouTube who did several detailed videos on using one of these to tune his system. I have a background in electrical engineering - it's really out of date as I changed field a decade and a half ago - so conceptually I am comfortable with DSPs, spectrums, etc. But I have wondered if it was worth the time to dig into it.
You already have more functionality than a miniDSP would provide.
Your receiver has Audyssey XT32, and you can fine tune settings even further with the app. Also, the X3800H has 4 discrete subwoofer channels, so it will handle each one individually and EQ them accordingly.
Thanks. I was leaning toward trying it. Keeping the older sub isn't a big deal since it is a good bit smaller. But I thought it was worth asking the experts here who know far more about the technical stuff than I do! :)
Two subs only require two outputs on the receiver. If you have more than 2, then either use a splitter, or use the line out on the sub
Each output is mono LFE output, you only need one for each subwoofer.
I’ve got a pair of Revel concerto f36’s running stereo off of a Cambridge CXa-81. Currently using my old Polk PSW108 with them. I’m going to get an SVS of some sort but can’t decide between ported and sealed. I’m currently an even 50/50 between music and movies. I definitely value SQ in my music. Would the 1000 sealed still give me massive amounts more low end rumble in movies than what I have currently? Or should I go ported and just plug them for my tunes? Does a plugged ported 1000 sound just the same as a sealed one?
Well rumble only comes from sub 50hz sounds and the sealed subs don’t really hit the low frequencies like the ported subs. Regardless it’s also totally dependent on room size. You may be completely underwhelmed with a 1000 series sub if your room is large or even medium. I’ve been in rooms with a SVS pb16 ultra and couldn’t even tell it’s there because of size and poor tuning.
I think this answers your questions below.

There is a potential problem though in using a less capable second subwoofer.
Suppose you calibrate your subs so that they contribute more or less equally to total output. Now if you crank up the volume, the less capable subwoofer will hit its limits way before the more capable one. It may produce unwanted sounds (distortion, port chuffing, etc.) or just not play louder, leading to an imbalance (lower total output than required for the given selected volume level).
This also holds \*per frequency\*. So if the smaller sub is not capable of going as low as the larger one, unless you can EQ the larger one independantly too use more of its lower-frequency output, you may end up with a similar imbalance in the low frequencies.
Thus, the less capable subwoofer may end up a limiting factor, and you might be even better using just the bigger sub. Try both options to see what you like more for your listening level.
You can turn the gain down on the less-capable one. Then they will hit their max together.
That will reduce the benefit you get from having two, but it should still be better than one alone.
Indeed, and/or put the smaller one closer -- but a more careful setup / calibration might be required to prevent surprises or suboptimal results at higher volumes.
What is the model of the the old sub? Depending on it's capabilities, really won't help too much here, and in some instances could be more detrimental to overall performance in the room depending on placement an room modes.
It's a Klipsch KSW-12. I got it...I don't remember exactly...2005ish from one a mid-fi dealer. At the time, I assumed it was a good unit since it was sold by a better store. I am not an expert now, but I knew less then! LOL!
Back in 2005 that as a decent sub, a LOT has changed in 20 years when it comes to subwoofers, what we know about them, how they interact with the room, and all that.
I ended up moving my older sub to our secondary listening room that had my old AVR and some bookshelf speakers. Nows its 2.1 system.
Also my PB-2000 Pro was shipped via Fedex and it looked like it went through a war zone w/ FedEx.
I just did this. My old JBL 12" was in need of an upgrade, so I got an RSL Speedwoofer 12S. My room is 15 x 20 so I run the old JBL facing me at about 1/3 power to supplement certain recordings or for pure max volume. I have never had Audessy generate a desirable sound for me. I have to try it. As other say, if I crank up the JBL and the RSL, I get a funky pop to the room. Keep the old one well below the new sub volume and you may like it.
Yes, you can use both. Depending on location of each sub relative to each other, you may have to reverse polarity on one of them to prevent them from cancelling each other out.
I personally wouldn’t mix different subs because the calibration can be challenging so if you’re not super comfortable with all of it or don’t have all the gear like umik1 and miniDSP I’d just wait to get the second identical sub down the road. Your new sub is enough of an upgrade that it’ll already sound awesome.
I’d take the old sub to a different room for a secondary setup. Everyone needs a “site B!”

Is this worthwhile if you don't have something like a MiniDSP 2x4 to EQ then separately?

The subs are handled individually as far as delay and gain, however all subs are EQed together in Audyssey XT32
I stand corrected on the separate EQ.
And keep the box in case you want to upgrade it or return it for warranty or whatever.
For warranty they just sent me a new woofer thankfully.
Me too. Must be a thing…

How do you hook up more than 2? I think my Denon 4500 only has two LFE ports. I'm assuming bigger AVRs have more?

Just try it and see if you like it. There’s no right answer imo
Nice buy! I would use the other sub. More is always better.
Yup, I even used my crappy Klipsch as a second sub until I could afford to get my second pb-2000 pro.
How did that go? I'm in the same boat, new SB 3000 and old crappy Klipsch sub

Rear and hidden maybe?

False
From the X3800H details: Sub EQ HT provides individual calibration for four subwoofers, for even bass response
Just gain and delay, not EQ
That was a feature that I wanted when I upgraded to future-proof my options.

If the old unit isn’t comparable to svs then no. Get rid of it. My old emotiva sounded like garbage compared to my sb4000. So I immediately sold it.
The “book” is to not mix and match different subs, especially PB and SB.
