The PV1D is probably the perfect sub for your system / listening environment - I wouldnt be looking to change ot for the MA.
While the PV1D is not going to give you room shaking thunderous deep bass can you honestly get away with that in a flat mate - you will be forever turning it down and thats the last thing you want to do with a sub?
It will give you clean bass through your crossover of 80hz down to whatever your room / the sub will do - probs around 40hz at a guess - that still deep enough to rumble you enough for enjoyment of a film - its the 50-60 htz range that you feel the pressure more anyways due to how your ears actually hear bass. The deeper the bass the more you need for your ears to hear it at the same spl
What The PV1D does have is built in DSP which is essential as the LX83 doesnt have any proper bass management.
Now changing over to the MA - a 12" sealed box sub you can get it to do deeper bass but will need to drive it hard / eq it hard to get deep bass / remove the room peaks etc which I doutbt you will get away with in a flat. Unless you drive a sealed unit hard it wont be doing deep bass with enough SPL for you to properly be hearing it - with eq you cna get that at the listening position but there is excess bass everywhere else - i.e. you downstairs or upsatirs neighbours.
I cant help buy comment on previous recommendation of 2 subs turned down low as being better than 1 sub turned up - that is not the correct thing to get the right amount of deep bass.
You dont have to have 2 subs to get even and transparent bass reproduction around the whole listening zone, you just need to get 1 setup properly.
RichMagnus can testify to that fact
I never claimed having 2 subs turned down low would be better instead of 1 sub turned up...??? Just for the record, mine are both set to the recommended "referencelevel" at 75db which works terrifically well within the acoustics of my current room. I had the same level when I had just the one unit. Increasing volume over 75db in either situation would prove overbearing.
Adding a second unit resulted in better bass precense, dispersion and feeling of 'weight' than I ever managed to get with just the one (and I tested placing it in the full number of placement options available to me). When I added the second AW12 into the equasion lower frequencies were transformed. Best of all, I can no longer localize where the bass is coming from, which was a tad too apparent with just the one unit. A friend of mine who has a lower end speakersystem than Apex had issues with bass from his subwoofer in his room. He descided to test adding a second identical unit, tried it in different locations and finally got a much smoother respons. All without too much tinkering. My favorite dealer has infact a dedicated and well treated listening room in his house, and he uses 4 subs to great success. Though in theory he should be able to manage the same with just the one...? Donno.......I kinda doubt it.
If I could afford a super high-end subwoofer and manage to dial that one in "perfectly" I'd still wonder what more could be acchived by adding a second one. Again, I'm not saying it's 'impossible' to acchieve even and transparent bass with just the one sub IF you have the means of perfect conditions and can place it freely exactly as you wish according to your rooms acoustics, and of course if the sub itself is up to that task, I mean different models work in different ways. For example, downfiring units tend to sound pretty dreadful in my room (I've tested 3 brands before I got Apex). Sidefiring happen to work the best here. But how many of us in 'real world' apartments have perfect conditions to set things up 100% properly. I think a large dose of HT fans out there have discovered the very same thing, seeing how many do infact have multiple subwoofers.
I think our friend gosahl can testify to that fact.

Yes indeed, i can concur. For me, having an additional AW12 subwoofer increased the presence and all round listening experience. There was a huge difference to movies and music.
