I'll put my asbestos-lined suit on in a minute...
My original Advent Large loudspeakers, from the early 70's, would be re-coned twice over the decades, but were never as good as the originals, although they needed every available Watt of power from my 68-vintage AR Amplifier to fill my den. Both are long gone now. Enter a pair of NHT SuperOne 2.1's 12/14 - and shades of my feelings of the original Advents... I know, the NHT's 6.5" acoustic suspension isn't as large as the 10" in the Advent - but the 'thud' was just as memorable. My Onkyo TX-8020 50 Wpc stereo receiver was doing it's best to fill my 12' x 11' office... until I tried a pair of smallish Klipsch PRC-made bookshelf speakers (KB-15). Sorry, I couldn't afford Heresys... at now a kilobuck per. I was on the track - and 11/15 found me ordering a pair of RB-81ii's - their largest, albeit canceled, bookshelf speaker with it's front-ported 8" bass reflex lf driver and 1" Ti horn hf driver. Amazon still has a few - $280/ea shipped. They are very efficient - and can deafen me in my office now (I bought a 50 Wpc Emotiva a-100 mini-X amp and feed it only from an Onkyo C-7030 CDP.). This is the best stereo system I've owned. They are not as 'harsh' sounding as others would lead you to think... but I leave the grilles on my speakers! Great bass, mid-bass, and high frequencies - quite decent midrange, too, and very efficient. VG dynamic range, too, although I haven't watched any disaster or war movies lately on it with NETFLIX - mainly music, ranging from early CD's of Paul Simon's 'Graceland' to several versions of Ravel's 'Bolero' - and even the ultimate - Tchaikovsky's '1812 Overture' sounds great (Just ignore the temptation to 'crank it up' during the beginning funeral dirge, lest you later get blown away by the cannon fire!). Dynamic! Okay... flame retarding suit is on...
