evilfrito Posted April 20, 2004 Share Posted April 20, 2004 Good afternoon everyone. I recently picked up an rsw-12 from my local dealer, and they seem to be working nicely with my stereo setup (two '77 heresy's). The weird thing is, I have my sub set to about 44 hz. It sounds great- it almost seems like my heresy's go a little past what the specs say online. they seem to be going down to about 40-45 hz , is this possible? Using tone generators, the response seems to be the smoothest blend when I set around 44 hz. I have heard from some that the heresy's are too quiet under 65 hz however.. maybe my ears are deceiving me. Anyways- that rsw-12 is pretty good at hitting that deep bass:) Quote Link to comment Share on other sites More sharing options...
garymd Posted April 20, 2004 Share Posted April 20, 2004 I use an RSW12 with my cornwalls for certain recordings that really go deep. It does a nice job, doesn't it? Quote Link to comment Share on other sites More sharing options...

CAS Posted April 20, 2004 Share Posted April 20, 2004 It really depends on what the purpose of you system is. For modern DVD home theater this probably isn't optimal, but for music it may work well. I think the response probably isn't what it should be crossed over that low (since the RSW-12 would only need to take care of the 20-44 Hz range) and your Heresy's are much more effective in at least the 60+ range. I don't doubt their abilities, however the ability to do something well/efficiently is a different story. I would try a slightly higher crossover frequency around the 70-80 Hz range for better balance and let each individual driver do what it was designed to do. Less strain, better/truer output, and longer life will probably result. My simple mains have the ability to go nicely down to 30, however I never let them. That's the job of my little earthquake maker Quote Link to comment Share on other sites More sharing options...
formica Posted April 20, 2004 Share Posted April 20, 2004 You have to remember that the Heresy's are -3db at 65Hz... and their lower end roll-off isn't a brickwall. Although I don't have the frequency response with me... they are probably down ± 6db at 45Hz which would blend in pretty well with your sub's x-over... as it rolls off inversely. That is why it is often recommended to use one x-over (either the reciever's or the sub's) to define the point as it is usually designed so that the their additive response is pretty flat. As mentioned, increasing the x-over point would reduce the Heresies load and probably reduce distortion a little. Glad those Heresys are rocking...
