Need a CR-1?
Simple answer is “No”. A crossover is not needed and many here do not use them in top, top line systems. Generally, when they do not, they are setting their crossovers below 50Hz even below 40Hz such that the sub only enters the picture at the lowest frequencies. They are also lucky to not have to deal with bass issues in their well sorted out rooms.
In cases such as mine where my main speakers develop a big ‘suck-out’ around 90Hz. No amount of available movement of their positions or of my listening position was able to eliminate it.
My solution was to buy a CR-1 and cross my JL Audio Fathom F113v2 at 95 Hz for high and low pass. Locate the Fathom using REW’s room simulator, fine tune its location with my ears and then adjust the phase of my Fathom, Run DARO and smile like crazy.
I achieved flat bass from 18 Hz to 300Hz, removed the low end load on my Amplifiers and created the best staging and frequency integration I have ever had.
