Hello everyone, I am considering an upgrade for my Energy esw-8. Now I am considering buying the R-112SW, however I have not been able to find many reviews on it. I have heard the Sub 12 in action which I liked a lot in terms of power, and they seem to be pretty similar to me (Keep in mind that I am not an expert in this field, so if I'm missing something please forgive me). Looking at the specs sheets (Sub 12) (R-112SW) it seems that the main differences between the two are: 650 watts vs 600 watts dynamic power in favor of the sub 12 24Hz-120Hz vs 24Hz-125Hz frequency response in favor of the R-112SW Bash vs All digital amplifier for the sub 12 and the R-112SW respectively Output: Max continuous output sub 12: 117 dB @30 Hz 1/8 space 1 meter Max acoustic output R-112SW: 118 dB (Down-fire vs Front-fire for the sub 12 and the R-112SW respectively) (Copper Cerametalic woofer for the R-112SW) My sub-questions are: How important is the dynamic power for the overall performance? Same for the frequency response (especially considering that the difference in frequency is in the higher end) What is the difference between Bash and All Digital and which performs better? Is the output information given on both spec sheets comparable? and if yes, which one has a higher significance (and thus gives the edge to the respective subwoofer)? Does the material of the woofer make a difference in sound/performance and then my main question is of course: In terms of performance, which of the two is better? The Receiver I am using is the Denon AVR-1912 (will probably upgrade in the future, but I don't know within what time-frame) I am aware of the fact that the Sub 12 has been discontinued, but in the case that the Sub 12 is significantly better buying second hand would be an option or saving up for the R-115SW and upgrading the Receiver proportionally(The latter not being preferred in terms of financial resource management but if the upgrade isn't worth it and the sub 12 not available it's better to save up and wait as to me this is a long-term investment). Thanks in advance! (Tldr; see main question )
I have a pair of sub 12's. The older of the two has a new problem. Blue light is on just fine, amp seems to go up and down power wise no problem however there's a constant tone in the sound from this sub. I've eliminated the LFE RCA cable as being the issue because the other sub works fine. General trouble shooting methods would indicate I should swap the amps to see if the problem follows the amp or stays with the driver but I'm hours away from selling the good one. Is this indicative of a blown amplifier stage or the drivers voice coil being fried? I see to remember about 10 years ago having a similar issue with a different brand of sub and it ended up just being the amp as the sub worked great afterwards as a passive driver when powered. Thanks!
