    I have Monitor Audio Silver S8’s ( 32Hz-30kHz ) and a Velodyne HGS-15. Running them with a Denon 3803. I was instructed to set the speakers to “Large” and had the cross over at 80.

    Last night while listening to LOTR I experimented back and forth from “Small” to “Large”. Bass was noticeably better with fronts on “Small” .

    If I keep the fronts on this setting am I going to lose midrange while listening to music in 2 channels?

    Actually, I found that the mid-range can actually improve by letting the sub do the bass to mid-bass. This also gives the bass a stronger foundation.

    This is because IM distotion is generated by drivers trying to do both bass and mid-range at the same time.

    Relieve the drivers of the lower bass and they can do a better job with the mid-range.

    Obviously, this depends on the driver compliment (2-way, 3-way, or 4-way) and type of speakers you have.

    Great article. Thanks!

    I recently put my system together and articles like that would be incredibly beneficial.

    Is there a favorite/popular place where I can find more articles?

    What Bruce said - midrange should be BETTER if you set them to small.

    This post has a quote of the post that article sort of grew out of.

    There are a bunch more on Secrets of HiFi as well:

    Some of the primer isn't very good, but some of it is also very good.

    I have fairly good size mains...Klipsch KG5.2's w/ a frequency response of around 34Hz-20kHz. I recently got an Infinity IL120S sub and a new receiver which allowed the 'Large' and 'Small' settings. Before getting the sub properly positioned and calibrated I liked the sound of music using the 'Large' setting much better. However, after crawling around on all fours (per a speaker positioning article found here) to find the optimal spot for the sub, in addition to calibrating it with the RABOS kit I received last night, I must say that I now prefer the 'Small' setting for music. I'm assuming that a mis-placed and/or uncalibrated sub can make all the difference in the world.

    The problem with that isn't that you are losing LFE, the problem with that is you have two different lowpass filters interacting with each. Can be a good thing if designed for, but I don't think the manufacturer of your sub plate amp and your processor did the design work together. The safe bet is to defeat your plate amp crossover if possible, if not turn it as high as it will go to get it out of the way.

    I have a Rava and have always had the crossover on it as high as it will go in order to get it out of the way. I was kind of curious about messing with the plate amp crossover because I went back and looked at the Rava literature which indicates:
