Maybe the root of the problem is not the bass frequencies. The speaker measurements shown in the stereofile link posted by Samhar show that the speakers have sensitivity of 85db coupled with 4 ohm and -41 deg phase angle at around 2k Hz.
This would suggest that your amp may have difficulties with this frequency. Since you suggest that you like mid-range, you maybe increasing the volume to make-up for the amp's shortcoming and in the process increasing the sound level of the low frequencies.
Cables won't help, speaker placement will to some extent but it may not be enough.
