I’m looking for two new subwoofers to replace my 20+ year-old Sunfire True Signature subs. While they’ve served their purpose, I’ve never been fully impressed with their performance for music, which makes up 60% of my listening (movies are the other 40%). Often, while listening to stereo channels, I’d turn them off and run my Polk R700s in full range since the Sunfires felt too boomy, even with ARC Genesis room correction.
I’m currently considering two sealed models: the Rythmik E15HP2 and the SVS SB17 Ultra. I prefer sealed subs, I don’t have the space for larger cabinets. I know either of these would be a massive upgrade. Still, I’m particularly intrigued by the Rythmik’s reputation for excelling with music—quick, tight, and detailed—while still delivering impressive performances for movies. Their measurements show they extend down to 14 Hz, and both models offer a very flat response curve with plenty of SPL.
I’ll say this: the SVS subs come with some impressive specs—dual 8” voice coils, dual mono amps (2800 watts), and a switch-mode power supply. That said, I’m not sure how much of that translates into real-world performance versus being more of an SVS marketing flex. The app, all the adjustable settings, and even the built-in auto room correction seem cool on paper, but I don’t think I’d use them since Anthem ARC Genesis will be handling the DSP in my setup.
My priority is something that integrates seamlessly with my system, providing the highest-quality playback for music (both 2-channel and 5.1 studio/live recordings) and enhancing the cinematic experience for movies. What are your thoughts on these two options? Does anyone have experience with either?
Accuracy is my top priority. I’ve tried everything to get the Sunfires to integrate seamlessly, but I’ve never been completely satisfied. I’ve adjusted placement, used REW with a MiniDSP, and relied on ARC Genesis. While these tweaks have helped somewhat, the subs still come across as boomy and lack the musicality I’m looking for, even with DSD playback. I’m hoping that upgrading to new subwoofers will be the solution. I’d love to hear about real-world experiences with both brands/models and see what others are using or recommending.
