I have been searching the interwebz and I can't find an exact answer to this so I figured I would go to the experts.
I am a bedroom/hobbyist guitar player. I play my Kemper through studio headphones 99% of the time, for that last 1% I play through these:
[Blocked Image: http://kurzweil.com/content/image/product_detail/199/medium/ks-40a_2.jpg]
100% wood cabinet using 12mm non-resonant MDF
3/4 inch (19mm) dome type, magnetically shielded
4 inch (106mm) diameter, magnetically shielded
Bass Reflex Port:
10Wrms x2 (at 1KHz, 10% THD)
100-10,000Hz (at -5dB)
1x Volume, 1x Sub Bass
2 pairs of stereo RCA jacks, internally mixed
(Line A inputs feature treble boost of 9dB at 10KHz; Line B inputs are flat)
(9-1/16") (23.00 cm)
(5-7/8") (14.80 cm)
(7-1/16") (18.00 cm)
(11.00 lb.) (5 kg), both cabinets
I bought them because they were cheap and I didn't really know what I was doing when I got the Kemper a year ago. They need to be aimed like lasers into my earholes to get the sweet-spot. If I move my head at all while I am playing the sound completely changes.
I would like to get something a little better(Bigger sweet spot, louder, better freq response, etc). I have zero interest in recording or mixing so I don't need super accurate, spendy monitors. These are just to play through when my ears get too sweaty from my headphones I would prefer not to spend over $500.
