[QUOTE="Bugsysiegals, post: 8743124, member: 682841"] Luckily my profession is in analytics and I enjoy using facts to classify and quantify things so I've created a dashboard to help. The dashboard allows me to apply filters based on budget, speaker size, goals (quality versus volume), ohms, watts, etc., etc. and afterwards graphs the eligible speakers across various categories in order to more easily visualize the best/top speaker(s). To better illustrate the value of the dashboard ... based on the data in the chart, it's easy to see the Fi Q Series sub has one of the lowest costs related to the Watts RMS you receive, medium cost for the SPL Efficiency, and is in the Top 3 for SPL Potential. This doesn't consider speaker build quality, perhaps some other factors which would be important, and perhaps SPL Potential isn't calculated correctly but the point is to show how visualizing data makes it easy to identify what you're looking for. That said, I need help from you audio experts/engineers to understand which valuable comparisons I should be looking at and how I can calculate their values. As you can already see, I've started with the following comparisons to begin illustrating the value you receive for the speaker price and to take a shot at SPL Potential. I'd like to add sound quality but have no clue how to measure and there's surely other valuable comparisons I'm missing too. [LIST] [*]Cost / Watts RMS [*]Cost / SPL (Efficiency/Sensitivity) [*]SPL Potential (Watts RMS * Xmax) ... are there other factors to consider? [/LIST] I've also the following speaker build component related specs available and have listed some of their values below. Are there other important attributes which I've missed and how can I use these in some calculations or classifications for low, medium, high, etc.? [LIST] [*]Basket Material - always seems to be cast Aluminum [*]# of Spokes [*]Cone Material - treated paper, Nomex, Kraft Pulp Fiber Reinforced, Pressed Paper Composite, Injected Pulp Matrix Fiber Reinforced ... [*]Voice Coil Former - not even sure what this is [*]Voice Coil Material - Aluminum and Copper [*]# of Coil Wind Layers - 2, 3, 4, etc. [*]Coil Diameter - ~2.5" to 3.5" [*]Magnet Diameter - ~6.75" to 8.75" [*]Magnet Material - Ferrite and Neodymium [*]# of Magnets - 2, 3, and 4 [*]Magnet Weight - [*]Spider Material - Double/Triple Progressive and Nomex [*]Tinsel Leads - Stitched, Wooven, etc. [*]Surround Material - Dual Layer Foam, Nitrile Butadiene Rubber, and Parabolic EPDM Rubber [*]Cooling - Radiator?
