[QUOTE="Jroo, post: 6211064, member: 574112"] I have the same question. I want to know what to look for to say if a bandpass will work. I was told to look at fs/qts and if below 50, sealed and bandpass work. I got these clearance woofers from a speaker builder and they said 0.5 sealed but could go band pass. Here are the specs they sent me, what do you think? Power Rating RMS Cont. 250 Watts Max Power Rating-Unclipped Amp 350 Watts Freq Response 25-150 Hz Nominal Imp 8 Ohms Voice Coil 2" 4 Layer FS 25.18 Hz Qms 8.8040 Qes 0.3579 Qts 0.3439 Vas 67.30 Liters Cms 0.3994E-03 M/N Re 6.93Ohms BL 17.505 Newtons/Amp Sd 0.034636 Sq. m. Mms 0.100017 Kg Hvc 0.980" Hag 0.375" Xmax 0.303" Xlin 0.605" Ref Eff 0.2885% Predicted Output 86.802 DB/1W/1M I have 2 tens and was thinking 4th order wired to 4 ohm load. [/QUOTE]
