    Just ordered the Monolith Plus FF in Cherry - having had the Paradigm Servo 15, Im hoping it will be as good - if not better! :D

    Ken

    Mods can you edit the title to Paradigm Servo 15 to a BK Monolith Plus Monolith lol

    It will be interesting to see if you hear much difference. The Monolith has alittle more bottom end output, but the Servo has a little more control...

    Hey Russell, if it can wobble the sofa like the Servo did, then I will be happy :D

    A quick question for you... is it right that the normal Monolith goes a bit lower than the 500watt plus Version??

    I went from a Servo 15 to a Monolith (non plus version) and didn't regret it one bit. The normal version supposedly drops a couple of Hertz lower than the plus but this shouldn't be very noticeable.

    I did have 2 Servo's - much better balance than the one and they really dug deep so I will probably be on the Phone to BK for a second Monolith + if i'm Happy :D

    Yes and no. The LAB 12 driver has a slightly higher resonant frequency, which means the Monolith Plus rolls off slightly sooner (2Hz maybe) but nothing significant. The Plus counters by going slightly louder and as room gain is factored into the equation too, you'd be hard pressed to measure, never mind notice, this slightly earlier roll-off. You would, on the other hand, notice the extra output and so that's the only difference of any real significance.

    Been playing about with my servo 15s today. REW now shows my mains basically flat to 17hz and -1.5db at 15hz and virtually all of the boom I had with the non equalized mains has gone.

    I was running the subs as a stereo pair next to the mains but it was never 100% successful. Today I finally got round to running them as a mono pair. One at the front of the room and one at the rear much much better.

    Using the X30 to crossover at 50hz. The mono outputs feed into both channels on an FBQ2496 and then REW for measuring and adjusting. Each sub channel was adjusted independently and some minor tweaks applied to integrate everything with the mains.

    The latest version of REW is pretty amazing what used to take me hours of tweaking is now virtually automated, very little in the way of post auto tweaking needed these days.

    I should have taken a print out of the waterfall before and after but I forgot it was pretty impressive clean up of decay

    Nice,

    I had a pair of Servo's and felt the bass had a much improved balance compared to the single Servo,

    This will probably be my route with a pair of Monolith plus's with an antimode

    Well... the Monolith + just did not do it for me hence me returning it

    I just could not get any real depth out of it - make no mistake - it has all the power when you crank it up - but I dont want to crank it up all the time just to get any benefit out of it

    For me the Servo is in another level to the BK in terms of depth at lower volumes - suprising to me as people and measurments beg to differ

    An important issue is the fact that its 90% music and 10% films and maybe the sealed servo with its 15 inch woofer that has the superiority

    Gutted in a way as the Monoliths finish was supreme for the money

    Just goes to show everyone's experiences are different and measurements are not the be all and end all.

    What's next on the audition list? :devil:

    That'll be much easier once HiFix start stocking the SVS range. Let us all know your thoughts.

    They are supposed to be getting stock by tomorrow, but still no prices as of yet.

    I feel the same about the XXLS400 in our sunroom. I think the root cause is that newer (more expensive) amp designs use DSP to vary the low Hz boost, maximising the extension at lower levels and backing off as the tap is opened. SVS (certainly on the SBs), KK, MKsound, Velodyne all do this.

    BK's amp uses a fixed LT circuit (soldered components) to extend response and therefore has to be tailored to not exceed Xmax at full tilt, wasting potential extension at day to day levels.

    So, if you are regular hooligan, BK makes you smile. If not, it makes you miss stuff the others can provide in the same or smaller space but for more ££££.


    My mate is running 2 SB12-NSD as stands for his MA Apex set and they are stunningly better than the single XXLS400 at normal levels. Just as clean higher up too.

    I'm very tempted to do the same.

    Interesting stuff :thumbsup:

    Looks as though Hi Fix (close to me) will soon become stockists of SVS and the Sealed SB13- Plus will be on my listening list as well as the above mentioned

    Interstingly, we had a look inside the SB12-NSD yesterday and I'm surprised to say the driver is uncannily similar to the Peerless XXLS......

    So, I went back to the Svsound site and looked at the driver pics there. When you load them up, the image names start 'XXLS'!


    I think we have an 835017 being used here.....ie the Alu cone version of the BK XXLS400 and Mono driver. It would certainly explain the very good music results as these drivers are very clean up high.


    Given Tymphany manufacture in HK/China now and the UK SVS SB subs also come from there I guess it makes sense....

    Having been recently re-united with a Paradigm Servo 15 - for me (and the other half) both agree that the Servo 'feels' and sounds far better than the BK Monolith Plus in my room.

    The low frequency wobble at lower volumes and a much cleaner bass makes it an utter legend :thumbsup:

    As with all things audio, there are no absolutes. The Monolith is ported, the Servo is sealed, relying on larger driver area. There is no guarantee the two will react the same in a given room, even if the drivers are in the same place.

    On paper, one of my DIY 15" subs should outperform a single Monolith, but in my old room it wasn't the case. However, the converse was not true - A pair of the 15" subs was so far ahead of a pair of Monoliths, it wasn't funny.

    You have the room that you have and the best sub is the one that works in it. EQ mops up the rest.

    Russell

    PS. Even if all the figures are the same, there's something inherently natural about the way a large driver moves air, compared to a ported sub. Even if you need more of them...

    I have the SB13 and its a beast. That man Russell likes it too ;) SVS have taken if off for sale to do some minor cabinet updates but I am led to believe that it will be back on soon. If it's better (I suspect it will but not by much) then it will provide many smiles as does mine

    Most Reviews suggest the SB13 is a great sub - for me tho the Servo continues to tick all the right boxes - Power / depth / Very low distortion and price

    Having owned the Velodyne DD18, the Servo did not equal it - but it was bloody close - to my ears (and trousers) 2 servo's bettered it - for around £600 for both, it was a no brainer

    I didn't have the benefit of exploring the limits of my servo 15 in the room I had but it could shift alot of air that's for sure
