Yeah, the Audiocontrol Epicenter allows you to adjust frequency and width of bass, have bass restoration, display and hold peak SPL values, and the built in SPL meter goes to 180 db.
im not sure the epicenter has the meter in it i know that the epic-160 does and it goes to 160. you can get them on ebay for about 215. Thats going to be a must for my system
audio control did it but that would be pretty pointless for most people because the audiocontrol mic is dying and the termlab is taking its place. the ac mic in there probably isnt the most up to date mic anyway, it would just vary like the other ones always did. the new termlabs are within .1 of each other i believe.
do these new ones you speak of have the bass maximizing capabilities like audio control which use the harmonics to replace the lower frequencies removed or faded during recording? The epic 160 came out like 6 months ago so im sure there wont be any problems with it.
