SSL SX310 2/3-way Pre-Amp Electronic Crossover with Remote Subwoofer Control

Work perfectly with various amp

私の様にアンプ3台でMAX1500ｗ以下が条件での話ですクラッシック中心の方にはイコライザーを挟んでも音質的に調整が荒い部分が多いので向かないと思いました

Overall, I don't think you can get a better electronic crossover for less than twice what amazon charges for this. I am only using it to tune by auto subwoofers since my amps don't allow for enough control. I can't say if this is clean enough for the high-level channels of a hi-fi system, but it handles bass cleanly. I wanted variable frequency and amplitude low frequency boost combined with an adjustable 12db crossover. Add in stereo/mono switching, multiple source control, plus phase selection and you have an ideal recipe for tuning your subs. I disassembled the unit and am quite pleased with the circuit board quality. The unit's power draw is less than 2 amps, so I can run it off my remote power amp relay and don't need to run a separate power wire. However, there is much room for improvement in the build quality of the case and switches. I would like to see the next model feature a more rugged body, flush mounted dials (so they can't get broken by stuff in the trunk), and perhaps some flexible mounting options. Oh, and I wish this thing was about 1/3 smaller.Pros:-Clean power-Great features-Decent build quality for the $$$-Soft power control-Very inexpensiveCons:-It's pretty big-Dials are not flush mounted (unprotected)-Kinda flimsy shell-Flashing chrome logo on shellUpdate, 8 years later and still working as new firmly mounted in my BMW trunk (which is still on the road as a daily driver).

Great product easy to use and full functional I recommend thus affordable piece separated highs mids & low perfectly

Construction isn't top notch, made of plastic, but ease of installation and improvement to sound quality was easy and superb. Definitely recommend for anyone looking to improve sound quality
