KEF-LS50 with REL T-Zero? Anyone?
I am putting together a second system in our casita. My source is a Bluesound Node2 and my power amp is an older Audio Research 100,2. (100 wpc SS). I just bought a pair of KEF LS50s. They are not setup yet so my curiosity about the need for a sub is speculative. This is a small room with limited space so if I think I need a sub it will have to be very small. Hence the Rel T-zero. It is the perfect size to fit in the open cabinet I will place it in. I have owned larger Rel subs in the past so I am familar with the brand. The Zero is a tiny sub...so much so I wonder if it will be worth the expense or effort. I've heard the LS50 and I know it has good bass....for it's size but just wondering if that extra bit of low end the Zero will provide will compliment the LS50. Knowing the limitations of the Zero I am not setting my sights too high but just wondering if anyone has heard this combo and can share their experience. Thanks

randyhat I wouldn’t use a sub larger than 2 x 8" max or at a pinch a very fast servo controlled 10" sub. As your crossing over from a 5.25" driver. 12" or 15" subs will be too slow to mate properly. I would also try blocking the port on the LS50 and going for around 100hz xover. https://www.stereophile.com/images/1212KEF50fig3.jpg And best maybe use two "tall" (24") subs and use them as stands for the LS50’s, like these I use, magic old Yamaha’s with servo control with linear amps http://www.audioreview.com/product/speakers/subwoofers/yamaha/yst-sw305.html Cheers George |
I ended up with the REL-T7i. I also was confused with all the options regarding the settings. If you go to KEF they recommend running the sub at highest volume level and highest crossover setting and use the KEF DSP app to control the sub. I talked to REL and got just the opposite advice. They recommend minimal DSP activity on the KEF end and utilize the filters in the REL to control the sub. Both KEF and REL support also suggest experimentation. So there doesn't seem to be a consensus. Having used RELs in the past and being accustomed to their recommended method for subwoofer hookup, I am following their advice....which means I am letting the LS50W run full range and controlling the REL to bring in the bass below the KEF. I am not utilizing the high-pass option in the KEF app.I have the sub low-pass frequency set to it's highest value (250Hz) and sub gain set to 0. I use the controls on the REL to make all adjustments beyond that...and pretty much have done that by ear. I started with the level and crossover settings at about 15 clicks from minimum and then adjusted from there by ear. I tried virtually every combination of sub/kef settings and feel like the current setting offers the best integration. As usual, many other factors will play into your decision but I have found what works for me. |
