    Default Pro and con questions

    I need educated opinions

    What would give over-all better sound, LV12F x 2 or LVX12 x 1?

    Also, I'm still trying to get the finer point of the sealed vs. vented down. What are the advantages and disadvantages of each? Generally, I'm still trying to decide if overall, I'm better saving and getting the most expensive option, or having a pair of less expensive ones.

    Right now, this will be music only, however, I want to slowly piece together a home theater system, so, they will eventually be used for both.

    Ultimate room size they will be in is sort of unknown. We are house shopping. Currently, they would be in a 11 x 15 ft room living room that is open to and has a shared wall with a narrow 9 x 15 ft dining room, both have 8 ft ceilings. The houses were are looking at are likely to have different layouts and sized rooms. But guess would be these will be in rectangular family room 12 x 20. Similar ceiling height.

    I read a detailed article that helped a bit with sealed vs ported, BUT in some ways, it created more questions. Very general summary seemed to be ported = boom and sealed is more authentic/natural. But I also got the impression that besides preference (to boom or not to boom, isn't the only question), but preferred musical style also factors in.

    I have a wide range of interest, but if I had to choose, based on interest and sound preference, I would side away from the boom. Generally, but maybe not always. then there is the home theater aspect. There, within reason, the boom can be good.

    Now I may have all the above wrong. Even if I have it right, I'm still confused as to which is going to be the best choice for me in the sealed vs. vented debate.

    With the Rythmik servo subs, I wouldn't stress too much over sound quality differences between sealed and ported. The ported will simply give you more low end output. However, between the 2 models you are comparing, there is only a 1.5 dB advantage @ 20 Hz with a single ported. You will easily recover that with a second sealed sub. Your biggest challenge with subs is going to be room integration - and your listening area is something that will be changing over time. Having 2 subs will give you a lot more flexibility with room integration now and in the future.

    Of the 2 options you are considering, hands down, I would go with 2 x LV12F.

    Thank you. That helps a lot.

    What you say about having two with room integration make a lot of sense too, especially with the unknown of the exact layout of our new house,

    I need to correct my previous statement as when I glanced at the Rythmik site I just looked at the picture on the products page (which does not show a port) and assumed the LV12F was a sealed sub given the context of your original post which I thought was asking about 2 sealed vs a single ported. I thought something seemed off given my understanding of Rythmik's product naming conventions and there was, the LV12F indeed has a single port whereas the LVX12 has dual ports. The output difference I cited between those 2 models is correct and I would still recommend 2 LV12F vs a single LVX12.

    However, that doesn't address the sealed vs ported issue. At 20 Hz, the L12 sealed would be down 3.5 dB relative to the LV12F and down 5 dB relative to the LVX12. The decision between 2 L12 and 2 LVF12 is a little tougher. If you're trying to save money, I wouldn't hesitate to get 2 L12. If you don't mind spending a little more, you could go with 2 LV12F for the extra low end home theater boom and rumble.

    Me too. In a small room two subs are always better than one, just to help control room modes. In a large "open plan" "room" however, you might be better off with one really large sub. IOW, one-size-fits-all doesn't work with subs. Just sayin'.

    I'm in a medium small room (21 x 13.5 x 8) with two LVX12s. Couldn't be much happier than I am now -- excellent HT, excellent music. They make my Sierra-2s sound like they effortlessly reach down to 20Hz or so, but the sound is still completely Sierra-2s. The LVX12s seem to contribute almost nothing to the overall sound of the system. IOW, these were amazingly easy to integrate into the rest of the system.

    I'd take two of the smaller LV12Fs over a single LVX12. Absolutely. But I'd also wait to see what kind of a room you end up with. No point in doing this (buying and positioning subs) more than once if you can avoid it.

    Thank you so much for looking into that. Spending a little more is the way I think I’m going to go. Somewhere recently I saw a post that called this a money pit of a hobby, I can see why. It’s addictive.

    Why not consider an F15 or E15? It's just a bit more than the 2 LV12F and you could always add another down the line if you need. I went with an E15HP for my 12x16x11 room, open to the back and one side -- sounds excellent with my S2's for both music and home theater.

    On their site, Rythmik recommends sealed for music only; 15" for combined.

    You could also call Rythmik (or Ascend) for a recommendation or try pm'ing enricoclaudio for a recommendation. He works for Rythmik, I believe.

    I tend to always upsell myself, so I was looking at those. It’s good to hear you like the E15 for music and home theater. I’ll check in with him and get his opinion. I research the heck out of things before I buy them and the good news is that I believe I’m going to love which ever one of these I end up with.

    LOL. I also do a lot of research before purchases. Anyways, I don't think you'll go wrong with any of the Rythmik subs.
