Ebenezer Joseph Posted July 16, 2019 Share Posted July 16, 2019 (edited) Hi everyone, newbie to stereonet, I'm trying to decide between the Svs pb1000 and the Krix seismix 3 mk6, which out of the two would be a better sub? I'm trying to get a good sub to pair up with my polk signature speakers for home theatre driven by a Yamaha rx-a1070.

hopefullguy Posted July 16, 2019 Share Posted July 16, 2019 (edited) depends on the cost.. there is a krix on gumtree https://www.gumtree.com.au/s-ad/como/speakers/krix-speakers-up-to-56-off/1223298358 but pb1000 come up for around $650 2nd hand. to be honest they would be at a similar level. just comes down to placement, placement and placement as to which performs better. 2nd hand or heavy discounted/refurb is the way to go buying a sub.

jamiebosco Posted July 16, 2019 Share Posted July 16, 2019 (edited) Just looking at the Krix specs online (no experience with this particular model) and having previously owned the PB-1000 (and several other SVS subs) I would personally take the PB-1000 hands down if the use is primarily home theatre. The SVS's much larger cabinet will provide a fair bit more efficiency down low , giving much greater output under 30hz,the tuning of the Krix looks to be a fair bit higher too The Pb-1000 lists an anechoic/groundplane freq. response of 19-270 Hz ±3dB with room gain you may get a little under 19Hz The Krix only lists an "in-room " frequency response of 22-200Hz with no +/- given (maybe -12dB??) According to this review, the Krix was 30dB down by 20Hz - and that was in-room https://www.avhub.com.au/product-reviews/sound-image/krix-seismix-3-v60-subwoofer-review-438075 ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Krix seismix 3 v6 Quote MEASUREMENTS: In our listening room, in subwoofer corner, measured close, the Krix Seismix 3 v.6 delivered an honest 29Hz to 153Hz. As is typical with bass reflex designs, once the limit of bass extension is reached, the dropoff is precipitous. In this case the output was down by 30dB at 20Hz (that is, making no practical contribution to the sound). ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The SVS PB-1000 measures much deeper These measurements are taken OUTSIDE (so no boundary reinforcement other than the ground) with room gain and boundary gain you should get flat to at least 20Hz https://referencehometheater.com/review/svs-pb-1000-subwoofer-review/ and from SVS Edited July 16, 2019 by jamiebosco 1 Link to comment Share on other sites More sharing options...

Ebenezer Joseph Posted July 16, 2019 Author Share Posted July 16, 2019 Thanks for the responses so far it seems like the pb1000 may be a winner. If there are any other Subwoofers brands and models that you can suggest please feel free to, I would be interested to know what other options are out there.

hopefullguy Posted July 16, 2019 Share Posted July 16, 2019 just realised you are in perth. that is the home of big subs so just wait and you will get one for sure. you might pick up a pb2000 as they tend to go + or - $800. much better than paying shop prices. 1 Link to comment Share on other sites More sharing options...
Ebenezer Joseph Posted July 21, 2019 Author Share Posted July 21, 2019 Just a quick update, I have bought both the Svs pb1000 and the Krix seismix 3 mk6 as I could not make up my mind and decided that best way to go about it is to introduce both subs in my room space and see which is the better sub. 1 Link to comment Share on other sites More sharing options...
MattyW Posted July 25, 2019 Share Posted July 25, 2019 Well, this should prove interesting. Interested in potentially getting a PB1000 myself to fill in bass for a pair of Open Baffles I'm assembling. 1 Link to comment Share on other sites More sharing options...
Ebenezer Joseph Posted July 26, 2019 Author Share Posted July 26, 2019 (edited) Just an update on the Subwoofers: I have had the Krix seismix 3 mk6 for a week now and got in the Svs pb1000 Subwoofer on Wednesday. I've tested both subs in room that measures 5mx4m with 4m ceiling height from floor. Both subs were tuned at 80db with a 50hz tone, both subs were plugged using the LFE input. My speakers consist of the polk s20 bookshelf speakers as my fronts crossover at 80hz an s30 for a centre speaker also crossed at 80hz and s10' s for surround and atmos effects crossed at 90hz in 5.1.2 configuration running off a Yamaha rx-a1070 av reciever. Both subs did great on music, the only difference was that the pb1000 was a little bit more punchy whereas the seismix 3 mk6 was a just a tiny bit more accurate. Movies was where I started to see obvious differences, the seismix 3 mk6 was a solid performer and did effects very well, however the ultra lows at about below 30hz was lacking, but like I said it is a solid subwoofer. The pb1000 on the other hand only can be described in one word.. Awesome! It was just that good, it's was balanced, but most of all I have never smiled so much listening to a subwoofer, that just shows how much I love it. Below 30hz I wasn't just hearing the sound, but I was also feeling it. In conclusion I would have to say that the winner is the pb1000, it is just balanced overall and given the price, its a steal for such an excellent performer. I highly recommend the pb1000, however if you have very limited space then the seismix 3 mk6 is a great solid choice.

MattyW Posted July 26, 2019 Share Posted July 26, 2019 Mmmm, I'm definitely going to get a PB1000 then. Thank you so much for your conmparison 1 Link to comment Share on other sites More sharing options...
jamiebosco Posted July 26, 2019 Share Posted July 26, 2019 Glad you liked the PB-1000 so much, I had one for a few years and they are such a solid performer , nearly bulletproof . I was pretty sure that movies were going to be that would separate these 2, so much of the enjoyment from movie soundtracks comes from the bass weight under 30hz Link to comment Share on other sites More sharing options...
hopefullguy Posted July 26, 2019 Share Posted July 26, 2019 dont know what seating you have in your room but given a 4m ceiling (wow thats tall) your room is very close to 3000 cubic feet..that calls out for a 2nd pb1000 1 Link to comment Share on other sites More sharing options...

Seismix 3 Mk7 | Krix WWW.KRIX.COM.AU MK The mk7 is a bit different from the mk6 on paper with an increase of 50watts rms more on the mk7 than the mk6, 300 watts rms (mk6) vs 350 watts rms (mk7) and now on the mk7 you get wireless built into the subwoofer for the optional adapter for the av reciever. I've got one on the way myself after hearing it in store, very impressive. Edited November 24, 2019 by Rolland 1 Link to comment Share on other sites More sharing options...

I was already getting one until i saw this thread and then they have the SVS PB 2000 at $1225 now lol. My usage would be 60:40 (Movies:Music), hence i need a bit of musicality in my setup. Kinda hard to get insights into this one as not many people heard both mk7 vs svs pb-x. The rest of my setup is in this thread (Krix speakers). Thanks!

Thanks! usually for more music use a sealed sub would be the go.. the sb2000 is $1115 delivered on ebay from distributor. as for how they compare you really wont know as most dont have both, set up in your particular room. if you have all krix speakers and that krix sub is "matched" with them then maybe that is the better choice? what type of music makes up that 40%.. how important is music vs movies. placement and EQ plays a big role, do you have the chance to put the sub in the optimum position or will it be the typical "it looks better in that spot blah blah".. variables come into the equation.

To be honest with I've only heard the pb-2000 in store, so my description of the sound is not going to reflect what it sounds like at home, but on paper there is really no comparison, the PB-2000 would destroy the Krix seismix 3 mk7, 500 watts rms (pb-2000) vs 350 watts rms (seismix 3 mk7), 17-260 Hz ± 3 dB (pb-2000) vs 22-200 Hz +/- 6db (seismix 3 mk7), there is realistically no comparison unless you are comparing the seismix 3 mk7 with the Svs pb1000. Sound wise, like I said I've only heard the pb-2000 in store, but I will say that I liked it a lot more for movies than I did with music, I found it to be a just a little slow and sloppy at times during music playback, but it wasn't too bad, however for movies it was fantastic. The seismix 3 mk7 I also heard in store and I found it to be cleaner and more musical than the pb-2000, but at the same time the seismix 3 mk7 gave a very solid performance for movies, it didn't dig as deep as the pb-2000, but then again the pb-2000 is physically way bigger than the seismix 3 mk7, so it was going to go lower anyway. At the end these are just my observations of the sound between these two subwoofers, and every one is going to have a different opinion. You have mentioned that your usage would be 60:40 (Movies:Music), how big is your room? Edited November 25, 2019 by Rolland Link to comment Share on other sites More sharing options...

Hopefully the siesmix 3 would fill that room. According to 1 of the sales guy I'm buying my setup from, he definitely said that the seismix 3 is more musical.

hopefullguy Posted November 25, 2019 Share Posted November 25, 2019 whatever you decide best get a move on. svs are rarely on special. sb2000 would be the way to go imo, the "other" person wont complain about the size so much and it is easier to fit in different places due to smaller foot print.
