The Double impact are a great deal for $3k, the bass and cabinet is a weak link
It us not tight Bass like with a $$ speaker thst us a fact.i compared with new ML powered Bass ,as well as Vandersteen speaker. All more money.
Bass will do cleanly around 30hz Cleanly a Striway concert grand only goes to 28hz and thst is low frequrncy vibration at that frequency . These cabinrts are not
That thick or ridged 30hz clean is very respectable not even 2% of music goes this low . There is no standards in Audio. Test yo be sweeps at 90hz is whst one of the guys did. If you bought the new SE model much better drivers ,and a little better crossover thst too us a weakness,, i have modded crossovrrs gif years
The crossover us the heart .use good Jsntzen copper inductors old Mills resistors US made 5.00 each sonicraft sells them. No Solen garbage caps and cheapest clarity caps at minimum use the New Clarity Copper S.A. caps very good caps for the money .I gave done tins of experimenting .There are many better still butt Erik
Is very frugal.
