Personally the MBL 126 standmount speaker with a good sub,or two
like the SVS -SB 4000 sub are a exceptional match why not only do you get a omni directional loudspeaker where even off axis it sounds exceptionally good
but this is their entry level speaker but have the same tweeter and midrange driver
thstis in. Their $$ 100 k Loudspeaker if you heard them you would buy them no box
resonsnce and detail and speed Thst box speakers can rarely equal , with 2 opposing mid,bass drivers , a friend in our audio club owns them and a end game speaker they say 82 db efficiency but more like 86 db or better since music is coming out in 360 degrees equally ,Xover the sub around 55 hz you then have a full range monster total outlay around $20 k , but this setup speakers at $50 k
just look them out great reviews Everywhere and with their grill screens off they look very unique with Thst exceptional MBL build quality.
