Yes, and shrinking the box will reduce the peak in output around tuning and flatten your frequency response. This does come at the price of reduced peak output though (before you add more power). Sizing a box is is all about balancing the trade off between getting max peak output (a large box) and getting a smooth frequency response and good sound quality (with a smaller box). There isn't a single "best" size. It's always going to depend on what kind of performance is most important to each person.

Glad I could help! Making the box bigger will get you more output, but only around the tuning frequency. You mentioned previously that you noticed output rolled off on the higher notes. Making the box bigger will make that effect more pronounced. If you want to get louder overall, you need to add power and/or add cone area (along with box size).

Should get a mustang

While 4K has been the latest craze, its not leaps and bounds better than 1080p especially at viewing distance vs screen size. Can be negligible. What you should look for to be 'next gen' so to speak is HDR (High Dynamic Range). This is where vast improvements will be made, as more content begin to utilize this feature. Thats a feature Id look for in a newer TV. Something like this may fit your budget and needs: http://www.bestbuy.com/site/hisense-55-class-54-6-diag--led-2160p-smart-4k-ultra-hd-tv-with-high-dynamic-range-black/5524900.p?skuId=5524900 https://www.amazon.com/gp/aw/d/B01E6PGT90/ref=mp_s_a_1_1?ie=UTF8&qid=1499174136&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=55H8C&dpPl=1&dpID=518-TDLzyJL&ref=plSrch

Not because of the refresh rate...but because it is a better screen. Refresh rate is generally marketing nonsense as long as you aren't really slow. Samsung, Sony or Sharp - the 3 S's were what you should buy for the past 10 years. That could have surely changed now though.

In that era, buy a Ford not that bowtie nonsense.

Its just a link to a web page. The calculator was created in Google Docs so I think it should work fine from your phone. It does take a lot of port area for these higher power systems. Its just like the exhaust on a car though, if you make a lot of horsepower you need to flow a lot of exhaust. I think the "9-12 sq in per cube" guideline for aero ports is robbing a lot of folks of a LOT of output. The nasty part about an undersized port isn't so much the port noise (which is annoying) its the port compression. Its the silent killer, it robs you of output but you don't hear the output you aren't getting. Its hard to notice the absence of something. It can easily rob you of 3 dB or more of output around tuning, that like throwing half your amplifier power (or more) out the window. As far as a port being too big and resulting in a sub bottoming out easier, that's at least 90% false. If the port ISN'T big enough it will actually result in MORE cone excursion around the tuning frequency, not less. Much below tuning I can see where a larger port MIGHT result in higher cone excursion, but at those frequencies you are at the point where the box is no longer providing mechanical control regardless of port size and you should be using something else to prevent mechanical damage (like a high pass filter AKA subsonic filter).

How much port area you need depends on the size of the box, the tuning frequency, and the amount of input power. What is your tuning frequency and how much power are you running? There really isn't such a thing as "too much port area", what can happen is a port can get so long that you begin to have pipe resonance issues, but that usually doesn't become a consideration until the port gets up past 40" long. Be wary of anyone who gives port area recommendations based purely on box size, that's like saying "if you are 6' tall you wear a size 10 shoe". It may not always be wrong, but it isn't always going to be right. The BEST way to determine how much port area you need is using simulation software (WinISD, etc) and seeing what port velocities you get. If you can't do that, here is a port area calculator that takes into account box size, tuning, and input power:
