12-inch SVS High-Excursion Driver - Room-shaking bass with subtlety and refinement

Maximizing every available square inch of surface area, SVS packed a high-excursion 12-inch driver and dual ferrite motor assembly into an acoustically inert, 13-inch cabinet. Thermal management is critical when dealing with such a powerful amplifier and motor in a relatively compact sealed cabinet. SVS engineered a vented pole piece and efficient high-power voice coil to keep the SB-1000 Pro subwoofer cool without impacting performance.

My favorite SVS sub purchase!
The SB-1000 Pro is my 5th subwoofer from SVS. I've bought the PB10-NSD, SB-2000, 3000 Micro, and now the SB-1000 Pro. I also bought a cylinder sub from SVS, but can't remember its name.

This 1000 Pro has quickly become my favorite. I use it for my PC work/gaming audio along with a pair of Adam Audio A7V powered monitors and a Topping E70 Velvet dac. I had been using the Micro, but it always felt a bit lacking in its "punch," especially with my music (industrial/electronic rock) and some games. I swapped in my SB-2000 and loved the improved punchy, tight bass, but not the sub's much larger size. I'm in a wheelchair and constantly bumped into the sub under my desk.

The SB-1000 seemed like the best option, so I ordered it and a set of the SVS isolation feet. Within the first 5-10 minutes of jamming some Nine Inch Nails, I was smiling broadly. The SB-1000 hits the sweet spot for a nearfield gaming/music setup. It's small enough to avoid bumps from my chair, yet delivers exactly the kind of tight punchy bass I love. The Bluetooth app makes it so easy to adjust any setting from my phone instead of having to reach the controls on the sub's back panel -- ain't an easy task from a wheelchair. LOL!

The isolation kit is a must, IMO. The 4 rubber feet keep my little sub from sliding all over the wood floor.

The only improvement I'd like to see for the SB-1000 is a metal grille, like on my SB-2000. It would offer much better protection for the woofer than the fabric covering.

Instantly worth it!
I'd been looking forward to getting this sub for nearly a year. The ratings, reviews, and awards for it speak to how great is really is! I was immediately impressed right out of the box with its quality in sound and build. It was instantly with the money for me, and the companion app is a really nice feature as well for full settings control!

Highly recommended
SB1000 Pro provides clean, tight bass in my room to supplement my Omega CAMs and my 20w tube amp. Perfect combination and the app is great.

Small box/Big sound
I waited a couple of months to review this unit, but it wasn't necessary. It sounds great now, as well as the day I unpacked it. I'm not going to get into the technical aspects because I'm not that tech savvy. Having said that, the app is easy to set up and understand. The sub is outstanding! It replaced a sub of comparable price but several years of age. The sound of this unit doesn't even compare.

First and foremost, I don't write reviews. Never have....
However..... This one and only exception is warranted.
This subwoofer is a monster and should be chased down the village square with pitchforks and torches........

The shear amount of effortless, solid, crisp bass is amazing. I've been a Klipsch subwoofer fan boy for 30 years before making the switch....


Klipsch who?????????

Android App sealed the deal.
Still experimenting with placement in challenging room. Phone app is essential considering close quarters setup. Using SB 1000 Pro to augment a pair of Paradigm Reference Studio 40 v2s driven by an old, but capable, Onkyo TX-8511 integrated amp. Being able to choose program material, volume and sub settings all from my seat was fun and productive. This little sealed box is simply awesome. Music is my primary reason for choosing sealed vs ported and I was glad to have other reviews to advise on this decision. If you're on the fence regarding SVS, stack this review on the pro SVS side of the equation. Money well spent.

SB-1000 Pro is exactly what I was looking for
I have been on the search for a solid subwoofer that can get down to 20hz. I originally had a JBL SUB200 8" subwoofer that has a solid response down to 34hz, but alot no response below that. So first I bought the Monoprice THX 10 V2 which, though it hit 20hz, it wasn't very tight sounding, and the cabinet didnt fit in my tight space requirements. So I got the SB-1000 Pro and it fits easily in my space, and Wow, the bass is tight. I went on to try others, but none have the flat bass response like the SB-1000 Pro, at least nothing under $600. I'm planning on buying another one to pair with my Klipsch The Fives powered speaker I have in my bedroom. I included the REW near field graph I made, showing it really does hit 20hz@-3db

Subwoofer sb1000pro; Not sure; still playing with it.
Purchased to integrate into my two channel stereo system (vacuum tube preamp/amp) and Klipsch Heresy I speakers mostly used for vinyl. Goal was to add a little bass to the Heresy’s which can be a little weak in the low frequency range due to their small cabinet size.
It took me a long time to learn haw to use the app. Biggest issue is that how it works doesn’t jive with what I thought I knew about subwoofers ant their operating frequencies. For example, my speakers bottom out at 50hz so I set the low frequency pass filter a a few clicks below that. That had no positive effect. I had to raise it to 150hz to get any real audible effect. played with the slope and ended up leaving it in the default 12db setting and 150hz to get the best result.
This brings me to my next point: It’s my understanding that low frequencies are pretty much non-directional so I’ve located my sub off to one side of the left channel speaker. It seems to me that the sub is in fact adding more to that left side than the right. That said, it could be that my settings have higher frequencies coming through to the sub that in fact do boost the left side. Again, still playing with this.
Third, as stated above I’m using a low power vacuum tube set up that has a quality that I really like. This sub is obviously a solid state device that adds it’s own quality that may be detracting from what I like about my tube gear.
Lastly, I’m low vision and was hoping that the app could be integrated into my accessibility features on my desktop iMac. I haven’t figured out how to do that yet.
I can’t really fault the product for any of these issues, but I’m not so sure that it has really added what I wanted to my system.
