    IS "Bass Obsession" deeply influenced by the type of music one listens to?

    Real bass note Hi everyone Just for us to remember... The very last low note on a concert grand piano is an A (la) wich produces a 26 hz wave. Very few home speaker or subwoofer can handle that low wave with sufficient efficiency to produce a realistic sound. And moreover that wave...

    Modern 6'' and deep bass : cone excursion?

    Hi The laws of physic have not changed : a 15'' cone moves a lot bigger amount of air than a 6'' one. But many modern quality speakers with only one or two 6'' whoofers seem to qive as much bass as a vintage bass reflex with a 15'' . Am i wrong in thinking that cone excursion is one...

    Suggestions for Kenwood L-09 replacement

    Whithin the budget limit u fixed, i think the only amps that could match the L-09 are the Kenwood L-O7M, or even better, the L-07MII. On fleabay I've got mine on fleabay for 400$ a few years ago. Of course, as u probably know, those amps will need a serious check up ... I had mine completly...

    How about Kef? Among 3way vintage speaker systems i would vote for Kef B110 as a fantastic mid range driver.

    What about L-07CII preamp?
