The pricing is at AE Speakers store. Also can select either 2 or 4 ohms. At this time an AE Speakers AV15-H costs about $249. The woofers are dual voice coil so the coils have to wire up in series to get an 8 ohm. Sure you can call to try to get a discount.

It is easier to deal with one instead to deal with a decision of which one is better during the design process. For a novice, I suggest stick with one woofer and play with the simulations. Sealed boxes will be the easiest.
If you want others, Exodus Audio, Elemental Designs, Peerless, Creative Sound Solutions, Sound Splinter, Sound Solution Audio, Ascendant Audio, Mach 5 Audio just to name a few.
In WinISD, set the amount of watts for the design, so you can see the cone excursions or Xmax. If the Xmax is exceeded at the frequency you are trying achieve, the woofer is bottoming out. Always design the woofer so it stays under Xmax at the wattage you want to put into it. Pe is the power limit of the woofer, but WinISD does not use this spec for the SPL output.
Another simulation that you can use is Unibox by Kristian Ougaard. It is a spreadsheet simulation, so you will need at least Microsoft Excel 2000 to use it. It is easier than WinISD.
In any speaker simulating programs you will have to convert Vb
into dimensions. If Vb
uses cubic feet, multiply it by 1728 to get cubic inches. When Vb
is in liters, multiply by 1000 to get cubic centimeters. Take either of these numbers to the cubic root or take the number to the third power. This gives you a number for length, width, and height. To convert liters to cubic feet, multiply liters by 0.0353. Do not mix US and metric measurements or else the box will be too small or too big.
I suggest buy the book titled "Speaker Building 201." It will teach you about the specs which are helpful while using simulation programs.
Do not need a sound card with phantom power. The phantom power is used for headphones. You just need the Dayton Audio Woofer Tester. It helps to measure the specs of the speaker driver and helps to break-in the speaker driver.
