Limiting a full range driver

My speakers, Reference 3A NEFES, have 2 full range 8" drivers. My question; is it better to limit the frequencies to 100 Hz and higher. My thinking is that the lower, sub 100 Hz signals interfere with the midrange too much with their larger cone movements. Or, is there no benefit to cutting out these frequencies?


I have been running full range for many years.  Don't limit the lower crossover at all.  You will get a much better blend and it will be more seamless running full range.  That is the idea of a single driver???

The sub can compliment the system and you will only have to play with the upper cross on the sub and how hard the cut off is.

Finally, if you are finding that your single driver is distorting because you like lots of bass or lots of volume then that is another story.  Most single drivers will fill a room but not rock it.

Dear @koestner  : Yes, doi t and your home system reorduction will shines as even before because what you will doing is to lower the IMD of those 8" drivers. You will have with out any doubt a higher quality performance levels and yes the  high-pass filter must be at 100hz.


Regards and enjoy the MUSIC NOT DISTORTIONS,


Funny..I`ve been running my Revel F52`s full range with subs from the start.

I`ve just recently put the Revels closer to the front wall and put the switch in back to the 'Contour' setting and I`m liking what I hear.

The three 'bass' drivers are only 6.5" so this position is sounding cleaner to me.

I would just keep the low pass setting of the sub at it's lowest setting (many are 40 or 50hz) to keep it well out of the lower male vocal range, which typically starts around 80hz, but some basement dwellers can get near 60hz.    I would only attempt to limit the LF of the main speakers if this doesn't give a satisfactory blend. 



This is one of those it-may-or-may-not things. Even if you crossover the drivers at 100hz, they are still 8-inch drivers. The midrange performance should not change since the relationship between the radiating area and wavelength (frequency) is still the same. The bass performance is probably not at the expense of midrange and instead attributed to the driver's excursion remaining linear throughout the frequency range at realistic volume levels.
