| If I were to purchase the new SVS PB2-Plus for example, would I see a big difference over the M&K? |
Firstly the SVS 20-39CS should/would be a massive upgrade from your present subwoofer for the following reasons.For comparison, the M&K 125 reaches 105db in the 25-63hz range, according to Tom Nuisanes performance charts, compared to 109.5db with the SVS 20-39CS, all parameters being equal.The SVS driver had not been upgraded prior to the review, which has a noticeable effect on improved headroom, more or less 3db of increased output.
Keep in mind, that the SVS driver was still from the old batch, figuring the additional 3db of clean output.So, in light of this information, the 20-39CS has slightly more than twice the clean output of the M&K, with lower distortion levels.
Now the PB2-Plus has been described as achieving almost duel SVS Ultra performance.In other words 5-6X the clean output of the M&K 125.Now whether the improvement will be worthwhile depends on the listening conditions, and the volume levels that you will prefer.The most important element is headroom and clean output at any given lvl, all of which will be greatly improved with the upgrade.
If however you simply listen at moderate volume lvls, then the upgrade in the absolute sense would be non-beneficial.I would recommend the 20-39CS or Pci, as either would provide a massive increase in clean output to your present sub, as well as extending lower with greater authority.Much cheaper as well, about $600 for the Pci(not entirely sure).

| So the next question. Out of the following three, which sub would you guys recommend with a Marantz SR-18/NHT Superone Surround set-up being used 50% for music and 50% for movies: |
Again, it depends on whether you need reference lvl bass(115db if speakers 'large', 121db if 'small'), or if you wish to attempt reference lvl output, it all comes down to your listening lvls.The M&K 5000thx ultra is a good performer but not amazing in comparison with your other three considerations.WSR Issue, measured 96db at 20hz, with no distortion limits, they simply cranked the volume with no considerations for power compression, THD measured levels or changes in tonal character, simply an SPL fest.
The 20-39pci(new batch) should equal or slightly outperform the 5000, the PB2-plus should be 3-4 5000thx subwoofers with regards to prelimary data specs(and used with proven tests with/against other M&K models in relation to SVS models).On a side not, the B4+ should produce almost 2x the clean output of the PB2+ from prelimary specs and by Tom V's comments, scary stuff.The Everast should produce even more high output lvls, and is very scary indeed.

| t.schwartz, you're going to spend for amazing bass. but, if that's what you want then that's what you want. for some people this process is almost neverending. sooner or later, you'll be going with a sunfire |
I'm not sure what you were attempting to say, as your statement was a bit incoherent.In any case, the sunfire should not even be considered in light of the choices that are considered for obvious reasons, however i sense a shread of humour on your part.For the uninitiated, the Sunfire Signiture(reference model) cannot even reach 105db at 20hz in a moderately sized room, even when distortion lvls was not measured, however it can achieve 100db at 20hz(albiet with high power compression lvls and driver irregularities or irregular driver motion).The result of using twin 10" drivers in a 13" cube.
p.s I hope that was a joke.
