Well the reality is that i have perfectly good curve with single SB13 (in house measured for best spot to the listening position(s). in 3200cb house without no dips. Frequancy response with ARC has no dips and one Peak at 60Hz that the position brings that i can EQ away. so there really is nothing to fill with two subwoofers right?
Why would i ever want to buy dual subwoofers if i have a spot in the house that fills the space without nulls/dipps in the low hz?
Cant see the point why im judged for buying one quality over two quantity.
Allso my next question is about what cant be seen from the curves (because they show at 72Dbb that they can bring <20Hz to the table) what is the point of upgrading from sealed to ported when in reality there is nothing to be measured ( SB13 has same type of curve measured (inhouse) as PC-4000 has (specs)
..Might be i end up blowing traces, if that happens i will let you know so someone in position of me dont spend dollars for nothing (well i got good deal and new equipment has 5years insurance) so its never nothing.
I have several thoughts to share. First, congratulations on your new sub! I think you will enjoy the PC4000. Second, speaking for myself at least, I won't be judging you on how many subwoofers you have.
For instance, the estimable @Jim Wilson
has always achieved very good results with a single subwoofer in his room, and I don't believe that anyone judges him for it. You are always going to get mixed advice on AVS regarding anything you are doing. You just have to trust your own judgment and listening preferences, and in this case, your measurements.
I sincerely doubt that you will believe that you spent money for nothing in moving to the PC4000, but as noted above, you will have to be the final judge of that. The lower bass frequencies are harder to hear, in relation to mid-bass and higher frequencies, as volume levels drop. You would be able to hear a 20Hz test tone at 72db, with no problem at all, in a relatively quiet room. Hearing sounds at that same frequency mixed-in with other sounds, however, would be very difficult if that 20Hz frequency were only playing at 72db.
The whole point in moving to a ported subwoofer was to give you more <35Hz SPL, especially for the special effects in movies. Your single PC4000 will be able to produce several times as much SPL at low-frequencies as your SB13 can. You may find that you really enjoy the low-bass sounds and tactile sensations for movies, although you may have to increase the volume of your subwoofer somewhat to take full advantage of the additional low-bass capabilities.
As with having a single subwoofer, you will be the only judge that really matters as to whether or not you do like the additional low-bass. In any event, the PC4000 will offer you several different tuning options, and some cool features, so you will be able to experiment very easily. (For instance, I think that the new top-mounted display makes it much easier to implement changes, including PEQ adjustments, post-calibration.)
One final thought involves the issue of dual subs. People often have more than one reason for adding subwoofers. Improved frequency response is one. Reduced localization, where people are more able to localize <80Hz sounds and mid and low-bass tactile sensations is another. Increasing total bass output by an average of 6db (averaged across the identical sub's passband) is a third.
I think it always helps to understand reasons why different people may choose to have multiple subwoofers. But, the biggest recommendation I would make is to just pursue the objectives that you
want to pursue in your HT, and trust your own judgment and preferences.
