Do you think you need a subwoofer?

Dear @mke246  : Good. The other parameter that we have to know with your Genelec's is at what frequency crossover those 8" woofers to the mid-range....

Now that I read the mijos  post I can see that the frequency is at 350hz ( I can't find it ). So, if it's at 350hz then the HP is desired to has down there but in the other side you are really listening at near field, even that the IMD is there and you can clean up. Maybe Genelec can help you to choose Genelec subs at your specific needs.

Dear @mke246  : I think that you are living a great first hand experiences listening to those very old recordings as that of Fats Waller. Congratulations.

Most collectors playing 78s are not going to hear the full potential of the records because their equipment is the equivalent of playing an LP on a Crosley. Bad stylus fit, bad EQ, suboptimal processing capabilities, or simply not playing an archival-quality copy. 78s will never sound like an LP-era recording, but you can make them sound like the best reissue CDs out there or better with the right equpment.

My 8351Bs are on stands on my large standing desk--sort of by necessity. They measure well in GLM software, and my room is treated with GIK panels. I mostly remaster on Sennheiser 800S headphones because I have a young child who’s usually sleeping when I have my ’free time’. I admit I haven’t put much thought into the concept of crossover frequency. The tuba and string bass on old jazz records sounds nice and tight, but I listen mostly to 78s probably limits my scope of reference when I listen to anything more modern. I’ll be researching subs and will probably pick up a pair when the time is right.

Genelec recommends 7370A subwoofers (around $4k each) for the 8351B but also has said in the past that 7360As (around $2.5k each) are fine if your room is on the smaller side and you listen at lower-to-moderate SPLs, which would fit my situation. Most people who implement subs with 8351Bs seem to leave the crossover frequency in the neighborhood of the default 85Hz. Still a bit on the fence--most of my music is pretty light on the sub-bass and that's a hefty investment for something I'll only get big benefits from on infrequent occasion. The 8351Bs are pretty strong at reproducing the bass on 98% of what I listen to.
