How accurate? How clean? How fast? Tight? Impact Bass? Can it go loud & low? How many Levels of bass it can play? Is it good for Music?
This Amp and Subwoofer combo generate the fundamental Bass Shrill and Clear on HT and Music use. Flat and natural Sub harmonics plays well. Technically the Price vs. Performance is similar to a EU$2k well-known subwoofer brands. To hear & feel is to believe.
Audition as many brands as you can & trust your ears & your ears alone.
Bring your branded Subs/DB meters to compare output, osci, spec a's etc..
- there's no secret to a great sounding Subwoofer it's simple physics. ;)
As always, AUDITION IS THE KEY!
PM/SMS me for audition.
