Hi,
I'm still learning about sound, and am hopefully a decent builder.
I'd like to try a modification to the Parts Express "Blast box". It would use the same amp (Class D 2.1 Amplifier 2x50W+100W, PE #320-635) and Subwoofer (DCS165-4 6-1/2" #295-198). I'd use a 10" passive radiator instead of an 8". The main enclosure would be ~0.5 cu-ft (14.1 cu-liters).
Rather than two midranges and two tweeters, I'm planning to use four full-range drivers "magnet to magnet" as with the "b8r".
I have been really impressed with the Tang Band W3-881SJF 3" drivers (#264-911). I was planning to use two ~200 cu-in (3.28 cu-liter) sub-enclosures, each with a center support having four holes and the magnets within 1/8" (3.5mm) of them.
Here are the TS numbers for the Tang Bands:
-Resonant Frequency (Fs) 100Hz
-DC Resistance (Re) 6.6Ω
-Voice Coil Inductance (Le) 0.8mH
-Mechanical Q (Qms) 6.44
-Electromagnetic Q (Qes) 0.41
-Total Q (Qts) 0.39
-Compliance Equivalent Volume (Vas) 0.07ft³
-Mechanical Compliance of Suspension (Cms) 1.32mm/N
-BL Product (BL) 4.47T·m
-Maximum Linear Excursion (Xmax) 0.5mm
-Surface Area of Cone (Sd) 32cm²
What would be the best way to port the sub-enclosures? Any other recommendations?
Thanks, feedback will be appreciated.
