First off i apologise to any one i must have hurt or p-i-s-s-e-d off with my late posts on this thread!.....i got the thing today my time exactly at 12;00 pm i unpacked it and everything was in perfect condition and top notch!..very good packaging by HSU RESEARCH!.....i have been experimenting different tunings all afternoon.The very first thing i noticed is that the satin black finish is really awesome i could say it kinda look like piano black but less reflection and shinyness!....''the thing is a lot more appealing in real then all the pics on the net that youv seen yet!''......oh and yes the driver is black and not grey!....i didnt get and had the time to get any measurment tools so yes i trusted my ears again but i know i can trust them enough to compare with other subwoofers i had before!.The subwoofer arrives with the 2 ports plugged so i listen to it sealed at first....so 2 ports plugged with EQ2 and Q 0.3 was the first i tried..since my receiver can manage the bass i desactivated the crossover on the sub...right out of the box it sounded already ''bigger '' then the paradigm sub12 and also the seismic12 that were my last 2 previous subs.
What i mean by bigger is that it was filling my room already better then those 2 others.I found that in sealded mode even not broken in it is as tight and clean then the sub12 but bigger sounding!....''surprisingly to me''...with the exeption that it already goes lower and deeper then the sub12...''already +1 for the HSU''...i must tell you that i tried changing the Q control but it would take a measuring tool to see the difference since you cannot hear the difference by ear!...so i decided to keep the Q contol to 0.3 for all and the same goes for changing the EQ you cannot make the difference by ear!...then i pulled out the 2 plugs and tried it ported so i wanted to see the two extremes...i listened to the same songs of course...this mode can only be used on EQ2 so i kept the EQ to 2.This mode was filling the room with greater pressure but i felt like missing that tighness compared to sealed and since i love tightness i decided to try it one port plugged and still on EQ2 and then BINGO!..i found it the best damn subwoofer i ever had owned and heard!!...no problem earing the mid bass...very punchy and clean and also tighter then ported! with a lot of deep extention.....since i was disturbed by some neighbours and some friends this afternoon i didnt had the chance to watch and listen to any movies yet....now is that an upgrade for me?..YES...do i regret this purchase?...NO!...in fact i am so happy!!...this is the best damn move i made since a long time!...does that subwoofer cost less then the paradigm sub12 i had YES!...is it better then the sub12..YES!....does it cost twice less then the sub12 YES!....NOW..is this HSU the best subwoofer in the shootout maybe and surely not according to the reviews and price gap between them...is this HSU the BEST BUY like Paul staded?..i think yes!...a subwoofer at this price range sounding that good!...well i want another and another!!....I know this isnt a professional review with any measuring tools and its worth nothing for some of you but i wanted to post it anyway....A HAPPY GUY IS A HAPPY GUY!

...OH AND YES I WILL GET MORE VTF-15H IN MY SYSTEM SOONER THEN LATER!!...thx.
