I was into car audio for a long time but have recently wanted to setup a fairly simple system in my home, mostly for listening to music, but I will also use it every now and then to watch movies. The first question I have is about my subwoofer. I need to know what you guys recommend for wattage to use with the sub and I need help with the enclosure. Here are the small thiele specifications on the sub. It is an eclipse 88120 dvc twelve inch subwoofer rated at 500 watts rms. Also if it helps the room I will have this setup in is my bedroom, its about 14 x 12 so it’s a pretty small room.
Eclipse:
Qts: 0.30
Vas: 90.6 liters
Fs: 27 hz
Qms: 5.00
Qes: 0.32
Pe: 500 w
Dia: 11.06 inches
Sd: 0.051 m^2
I modeled the sub in winLsd and I came up with 2.7 cubic feet internal enclosure tuned to 27 hz. I don’t know if this is the ideal tuning frequency for the sub or the ideal volume what would you guys recommend? Also a friend of mine had this woofer in a 2.5 ft^3 enclosure, slot ported on 180 watts rms and said it was very loud. Would you guys recommend this or maybe a bit more power? I was thinking of using a parts express amplifier 150 watts rms class a/b for $110 part number #300-804.
My second question is about my main speakers. The drivers are a component set from Image dynamics with crossovers. They are 6.5” carbon fiber drivers with phase plugs and 1” silk dome tweeters they are rated at 150 watts rms.
Thiele:
Qts: 0.39
Vas: 6.0 liters
Fs: 70.79 hz
Re: 3.8 ohms
Qms: 3.57
Qes: 0.43
SPL: 91.00 dB
BL: 8.12
Dia: 5.71 inches
Sd: 0.0013 m^2
I talked with image dynamics to get the tuning frequency for these and I came up with 58hz and the enclosure size I came up with is 0.3 ft^3 I would appreciate it if you guys could give me some tips on this. Does it look ok or could it be better? Maybe these would sound better sealed?These will be powered by my Onkyo tx-840 receiver at around 120 watts.
