Last week after months of debate with myself about upgrading my subs I Finley did . After researching all kinds of brands and sizes of new subs I pulled the trigger on these . Had many conversations with them about my room it size my whole setup I decided on the SVS pb-1000 pros . I read lots of reviews on here and other forms . \n\nFirst of all my old jbl subs were close to 25 years old still worked but were sounding tired to me so there retired and need work on the amps and connections need replaced ( rca’s ) as they were acting up helped with my decision lol ! \nNow for the Pb-1000 pros I wanted night and day difference right out of the box these are outstanding subs . Easy to setup and interface with my speakers and avr only problem I had was on my first setup calibration I didn’t notice that they weren’t on lol and did the whole 8 point calibration only to see the subs were not recognized fixed that and ran again only to find that for some reason it was the best results I’ve ever got with YAPO in my rig . \nCould it be just way better response across the sweeps or better quality subs with better mid bass and really deeper extension in the lower frequency’s my jbl towers are not lacking in mid bass and do play down Farley deed but this is a different cleaner powerful sound in my system that was never there with the old subs . \n These subs are very well made not real heavy but not light either. These are capable of very deep powerful output with bass I never knew that was in any soundtrack I’ve tried . There very clean deep into your bones deep for lack of a better description. \n SVS is great to work with very knowledgeable and really seem to want to help you get every penny out of what you bought and help get the most out of it . \nIam not a reviewer lol but my take is these are incredible subs , play deeper than anything I’ve herd with precision I’ve never had before . \n These sound really good with music in two channel and just amazing with concerts on Blu-rays , scads and I was surprised at that . Movie soundtracks and tv shows now have bass you can feel are not here if that’s a thing . Two of these can seriously slam you back in your seat with authority. The biggest thing was my wife’s reaction to these when she noticed the difference I knew I did good she’s very impressed with this upgrade and she’s had good sound in our home for over 30 years lol !\n\n These are winners in my setup and room and Iam sure they would be in about any room . Yea you can go bigger and more power too but I’d be hard pressed to say I’d need better with this setup I have . \n The come with crazy control options with the app and I’ve yet to really play with the peq settings and room gain compensation and a few other settings these have but setup was a breeze easy and I’d say very accurate with our useing like rew measurements but I may give that a go too . I asked for port plugs and they sent them free of charge the next day . \n\n Myself in my system I’d highly recommend these in a duel setup yea they make bigger and better form SVS and other companies but after useing these for a few days and playing with some settings in the avr I’d be hard pressed to say I made a bad choice in these I’d definitely buy again Iam not sure I’d go bigger not finding these lacking in any aspect . Iam very impressed with these they do exactly what they claim and way more .
