Wherever a TRIO finds a new home, there is an appropriate bass solution available from Avantgarde Acoustic. Well understood: it is not always possible to go for the top level solution, means up to 6 BASSHORN modules. And it does not have to be! Even the SUB231 benefits from the same material pool of the larger horn loaded subwoofer variants. Because one thing should not be missed out, no matter how limited placement options may be: the power of palpable bass sound waves!
