Greetings all, I've been discussing speakers on a facebook group and I've been told that audophiles seek a linear reponse all the way down to 20Hz, and that since my RP-250F have a "db" (?) of only 35Hz I should consider adding a subwoofer to my setup. I looked up facts and the official specs say "FREQUENCY RESPONSE 35-25kHz +/- 3dB" and the freq curve of a larger model (RP-280F) seem to indicate that the response does drop off under ~35hz. Now I have a couple interrogations: Is it a real problem? I like bass, I slightly EQ for more bass on the amp and am generally happy with the thump the speakers give, but am I missing something in the 20-35Hz band? To me there is not much musical content in that range.. How can I fix it? I didn't try to software EQ that narrow band, but as my speakers are bass reflex I presume it would be useless, as the membrane doesn't actually produce the deeper frequency, but the resonnance does? I looked at a few subwoofer and the cheapest that goes this low I found is the Earthquake CP-8...355€ for a 15Hz band is it worth it? the whole system without a source cost me about 1200€... Feel free to move this thread even tho I'd prefer answers from the sound science crowd. Cheers!
