whowillbe Posted March 7, 2007 Posted March 7, 2007 Hi people, I've got my second svs sub and I used a Y splitter to split the signal from my AVR to my 2 subs. However I noticed that the Pb12-nsd is very soft whereas the Pb12+/2 seems to be operating as normal... any idea? Also I noticed that then i turn off the Pb12-nsd while the Pb12+/2 is still on, the Pb12-nsd will produce a sound a bit like its farting (dun laugh hor) whereas it wouldn't happen if the Pb12+/2 is switched off first. (if the Pb12-nsd is operating alone, there wouldn't be any sound too when i switch it off)... any idea?
whowillbe Posted March 7, 2007 Author Posted March 7, 2007 Did you check the volume level on your PB12-NSD? Yup, even at full vol, the sub sounded very soft... so i'm wondering is it due to the way i connected the 2 subs.
media2368 Posted March 7, 2007 Posted March 7, 2007 I am thinking your Y-Splitter may be faulty...Can you swap the 2 cables on the Y-Splitter and test again? If it is still the same, try swapping the sub cables. REMEMBER TO LOWER DOWN THE VOLUME ON YOUR SUB AND AVR BEFORE YOU TEST IT :)
Jason Yeo Posted March 7, 2007 Posted March 7, 2007 I've got my second svs sub and I used a Y splitter to split the signal from my AVR to my 2 subs. However I noticed that the Pb12-nsd is very soft whereas the Pb12+/2 seems to be operating as normal... any idea? If both subs at different position , it could due to difference response . Furthermore PB12+/2 is much powerful than PB12nsd . However,even both r PB12+/2 , one could sound softer if both at different position . Just make sure the PB12nsd is really working and not just vibrating cause by PB12+/2 ;D Also I noticed that then i turn off the Pb12-nsd while the Pb12+/2 is still on, the Pb12-nsd will produce a sound a bit like its farting (dun laugh hor) whereas it wouldn't happen if the Pb12+/2 is switched off first. (if the Pb12-nsd is operating alone, there wouldn't be any sound too when i switch it off)... any idea? Yup , it can fart if the sub is in ready and not standby mode . I also notice most powerful subs also can fart including sunfire ;D. Nowadays I just left it at standby mode so long time no fart liao .

Hi Jason, it can't be the difference in response because when i connect both speakers, I purposely set the PB12+/2 volume to 0 and the PB12-nsd vol to max, and the 12-nsd is still very soft... the 12-nsd is only back to normal when i connect the pb12-nsd singly to the AVR. So 1 farting sub is normal when 2 subs are connected to the same avr with the other sub in the ready mode... ha... and i was wondering why my sub was farting... :o
Jason Yeo Posted March 7, 2007 Posted March 7, 2007 Hi Jason, it can't be the difference in response because when i connect both speakers, I purposely set the PB12+/2 volume to 0 and the PB12-nsd vol to max, and the 12-nsd is still very soft... the 12-nsd is only back to normal when i connect the pb12-nsd singly to the AVR. Then maybe the Y-splitter got problem (contact loose?) . So far I split and split and split using Y-splitterss and just kana 1 time humming on a sub because not push in tight enough ;D . The rest of time so far so good . Try to buy Y-splitter that is not cover with plastic type(the cheapest) . The connection can always be loose and cause hum or whatever . Even those slightly better quality , if possible use one another to try the RCA female holes before you buy . Sometimes the 2 female holes got diff in diameter whereas one is tight and the other is loose . Btw, if you max the volumn for PB12nsd and still soft , I am sure it is not getting any signal at all and the sub is not operating . The vibrating from the driver is cause by other reason. When sub is operating , the driver need to move in and out and not just vibrating .
media2368 Posted March 7, 2007 Posted March 7, 2007 ... the 12-nsd is only back to normal when i connect the pb12-nsd singly to the AVR. The farting is normal... Did you check the Y-Splitter?
whowillbe Posted March 7, 2007 Author Posted March 7, 2007 The farting is normal... Did you check the Y-Splitter? nope... will check to tonight.... OKAY... to all xtremers with FARTING SUBs... its an okay phenomenon.... fart fart... ;D

However I noticed that the Pb12-nsd is very soft whereas the Pb12+/2 seems to be operating as normal... any idea? Hi people, I've figured out why the PB12NSD is so soft... the answer is simple... its relativity at work.... hahaha the PB12NSD is working fine as normal (now sold to steel already) its just that the PB12+/2 is super duper powerful like x4 the power...
tsammyc Posted March 15, 2007 Posted March 15, 2007 More like 3x the power with 900W. My PB12+/2 is rattling so many things in my study, that I have had to tune it down until I find some time to silicone everything down, especiallly the ceiling....

My PB12+/2 is rattling so many things in my study, that I have had to tune it down until I find some time to silicone everything down, especiallly the ceiling.... i'm not good with the technical details but all i know is that the PB12+/2 is simply powerful... just amazed by the amount of air that it can move... silcone the ceiling??? how do you go about it??? and by saying ceiling, i presume that you're refering to the false ones right?
Jag Posted March 15, 2007 Posted March 15, 2007 Can't compare la.......... NSD vs PB12+/2.........I'm still amazed by my twin towers till today....... The amount of air and bass that hits you in the stomach is really outta this world. :) ;D

The amount of air and bass that hits you in the stomach is really outta this world. :) ;D yeah you're rite... phew its a good thing i went with a new pb12+/2 instead of getting a 2nd pb12nsd... its much more economical in terms of the amount of air moved per dollar.
Jason Yeo Posted March 15, 2007 Posted March 15, 2007 12+/2 is much powerful but 12NSD should not be that weak when you turn up max vol ??? Hi Jason, it can't be the difference in response because when i connect both speakers, I purposely set the PB12+/2 volume to 0 and the PB12-nsd vol to max, and the 12-nsd is still very soft... the 12-nsd is only back to normal when i connect the pb12-nsd singly to the AVR. For deep bass , the NSD sure "pop" but if mid bass and turn to max , it should be as good as 12+/2 at half the vol , I guess . And you mentioned when connect direct to AVR , NSD is back to normal ???

Go for a second 12+/2 in future to make it better ;D Oliverlim is doing it with 4 SvS in his hall setup ;D
whowillbe Posted March 15, 2007 Author Posted March 15, 2007 Go for a second 12+/2 in future to make it better ;D Oliverlim is doing it with 4 SvS in his hall setup ;D huh.... the pb12+/2 is already causing my house to tremble at 10 o'clock position... i dun dare to image what a pair of these would do to my place.
Jason Yeo Posted March 15, 2007 Posted March 15, 2007 huh.... the pb12+/2 is already causing my house to tremble at 10 o'clock position... i dun dare to image what a pair of these would do to my place. Simple , settle the house rumble and add another one like oliverlim ;D. I bet tsammyc will add another in future if all rattling gone ;)

And you mentioned when connect direct to AVR , NSD is back to normal ??? hi jason, i mentioned that the nsd is back to normail when connected singly to the avr... this was a mistake in the sense that the nsd was operating normally when its connected singly of together with the +/2... the reason why the perception of the nsd is operating normally when connected singly is because it doesn't have the +/2 outputing at the same time so by itself(nsd) it sound loud enough, but once i connect both subs to the avs, the output from the +/2 simply overwhelming the nsd thus causing the nsd to sound anaemic.... trust me... the nsd at full gain cannot match the +/2 at 10 o'clock position.

Oic . I do have a 12isd too but my side may be different feel due to the position . When both operate , it may have cancell or due to the 12+/2(as what you mentioned) , you feel nothing coz already cover up by 12+/2 . For a 12isd and 12+/2 at same position , the full gain can match with 12+/2 at 10 o'clock for above approx.40hz . Btw, I have not yet tried any of my subs at full vol position coz it is too dangerous to me , my room and the sub itself, above is all my guessing only :P

Yup shouldn't be if phase also the same . Then conclude the 12+/2 cover the nsd completely ;D Actually I feel it is a waste you sold away the 12nsd coz it can do something special where a single SvS cannot be done . :)
