United Statesmy 2nd PBS-2000 pro to make it a dual sub setup
the first one was excellent but definitely needed higher volume as was suggested initially for my room 15x16x10. i thought of going one step higher with PB 3000 or 4000 instead of this one but then settled with 2000 pro with the idea or adding another sub later. it made a hell of a difference with the second one paced diagonally. now even at low volumes i can see the difference when watching movies. no wonder why everyone who has 2 subs always suggest that way. once you hear it you will not go back. also the sound is very clean and deep and doesn't feel flat.
USPB2k Pro
I could not be happier with this sub. It is incredible! Not to mention the fantastic customer support when I decided to return the PB-1000 Pro for the 2k. SVS has a customer for life!
USPrecise low chest pounding bass
Precise sound, extreme low thunder surrounding bass great for movies and great for music. Just spot on, can’t say enough about customer service team dealing with me for hours debating and planing out my room and set up. The best subs and company I’ve dealt with hands down
USI cannot say enough good things about SVS as a company and the products they provide.
This PB-2000 Pro is the second subwoofer I have purchased from SVS. I'll try to sum up my opinions of the PB-2000 first. Then for those that wish to read further about my experience with SVS that makes me rate them highly as a company, read further. I've been able to listen to the PB-2000 for about a month now. Using different sources. Mostly BluRay live concert recordings in DTS master audio. BluRay movies. Multiple sources streaming through my Apple TV. Mostly Netflix, Prime, Disney+ and Apple TV content. Also remastered classic rock recordings done in multi-channel now on BluRay. Find remastered recordings done by someone that really knows what they are doing and it can be a whole new enjoyable listening experience to what you've been listening to for years. When it comes to musical abilities. This sub blends in seamlessly in my system. I can really appreciate how it beautifully reproduces the sounds of a traditional acoustic standup bass. Not to mention how well it sounds with electric bass guitars. The best thing I think I can say is this blends in so well and fills in the bottom end so seamlessly, I just forget it's even there. It sounds great. I'll list later what equipment I use. As for BluRay movies. What can I say. Sound effects galore. Explosions will get your attention. Those quiet moments that instantly transition to something surprisingly loud can make you jump. I haven't listened to a lot of subwoofers. But I stopped looking and listening when I found SVS. They just seem to reproduce sound without that fake boominess. Some people like that, I do not. I like accurate bass reproduction. SVS delivers that in my humble opinion. Please remember that the PRODUCTION QUALITY of your sound source material and how well it is mixed has a huge affect on what we hear. As with any sound reproduction equipment, garbage in, garbage out. Use quality source material and components and you'll sit back and enjoy. I also really appreciate the black ash finish. It closely matches my existing speaker system. I am not a fan of any app to control my devices. In my humble experience they usually have faults and do not work for me. Call me old school. (I am over 60 but have been an audiophile since I was a teenager and am not hesitant to check out and use new technology, as I've done throughout my working career, if it is GOOD tech). In the case of the bluetooth SVS app, my seating position, 20' from the sub, line of sight, no obstecles, does not maintain a connection. Not a big deal for me as once I set everything up properly originally in my system, I don't bother to change anything. No need to. If you're someone that just has to have an app, you may find this a negative. I do not. As to my system I incorporated the PB-2000 into. I've had this setup for some time now and it just works and sounds well in my listening environment. I use a Marantz AV7005 pre/pro, a Rotel 5 channel RMB-1075 power amp, Paradigm Monitor 7 V3 5 speaker system, Sony BluRay player, Apple TV 4K, Sony 5 disc changer SACD capable, a Mac Mini as a media server and an LG 60" plasma TV (I have yet to find a TV that can reproduce skin tones as accurately as my LG plasma. I'll use it until it no longer works). My listening area is my living room in an old farmhouse that has some modernization done over the years. It is 15' wide by 23' deep with a ceiling just under 8'. Wood frame, drywall walls and ceiling. Most of the wood floor is carpeted with 8' on the deep end where the main equipment and TV are located, exposed wood floor. I used the recommended settings for the sub provided by SVS for my speaker system. I then used the Audyssey Auto Setup of the Marantz. Using the microphone in as many positions as the system permitted. The only changes I made from there was to adjust the input levels from different sources in the Marantz so they would be similar. When looking at the adjustments the Audyssey software incorporated, they are minimal. This has worked well for me. I used the same technique with my former SVS subwoofer. It just seemed to work for me. One other note. With the purchase of the PB-2000 I also purchased the SVS SoundPath subwoofer isolation system. I was able to compare the sound with and without the isolation system. Remember, I live in a 100+ year old wood frame farmhouse. WOW! I cannot believe what a major difference the isolation makes in my particular installation. Without the isolation there were things that would vibrate and rattle in the listening room and beyond. With the isolation- - it's pretty much eliminated all of those. Which makes the bass produced by the PB-2000 that much more detailed and accurate. Well worth the price. I wouldn't buy another sub without this isolation. As to why I cannot say enough good things about SVS as a company. The other SVS subwoofer I have is a PB12-NSD I purchased some years ago. I truly enjoyed that subwoofer also. Earlier this year I was having a very random, very intermittent unfavorable
