Just wondering if there is a "small" folded woofer that can give me 30-800Hz, or a direct (ported or sealed) box. :D

 

If you can tolerate 60 Hz instead of 30 Hz, and maybe add a dedicated sub, then any of these will deliver 95+ dB from 2.83V in a sealed box:

 

Woofer | F3 | Box Vol ft³ (without stuffing) | Sensitivity dB@2.83V (from WinISDv07)

 

Crites CW1526 | 56 | 5.20 | 98 (4 Ohm)
GPA 3154 | 58 | 3.67 | 98
GPA 416-8B | 59 | 4.80 | 98
Eminence Impero 18A | 57 | 6.68 | 96
Eminence Kilomax Pro 18A | 50 | 9.55 | 96
Eminence Omega Pro-18A | 60 | 4.62 | 97
Eminence Omego Pro-18C | 60 | 4.46 | 100 (4 Ohm)
JBL 18SWS800 | 58 | 4.09 | 95
JBL 18SWS1000 | 53 | 7.42 | 96
JBL 18SWS1100 | 50 | 9.21 | 95
RCF LF21X451 | 56 | 5.19 | 96

Hate these CraigsList people :(  3 different sellers; 20 messages, even put "money down." NO RESPONSE :( (Was for a Crown amp, dual 18" subwoofer and dual 15" yamaha Pro speaker.)  Oh well ... really did not need those items anyway :)  

 

OK; maybe I'll try some Yamaha 18" single subs.  Model SW118V.  Specs say 30-2000Hz, so that will give me a nice range.  Anyone ever heard these? Trying to communicate with seller ... yeah; CL :(  We'll see :D
