Hello,
A couple of days ago I hooked my L20s up to an old Sansui 2000 that I just restored for fun (near mint $5.00 thrift store treasure). When checking out the sound with a Chet Atkins disc I experienced two problems that I have never had with these speakers, LOTS of port noise on the low guitar notes, and one cabinet even vibrated/rattled like something was loose (can actually feel it on the top of the box when it happens). I removed and inspected the drivers from the suspect cabinet, as well as checked all the glue blocks etc. inside. Everything seemed solid and as it should be. The drivers were not loose on the baffle. The sound of this little combination is very decent and a lot of fun, the old Sansui has a big, fat sound (pleasing distortion perhaps ) ? Does anyone have any suggestions, especilly for the port noise issue? This little amp plays LOUD and I'm not even going near "12:00" on the knob so I don't think I'm over driving them. DC at the speaker terminals is less than 5 millivolts, so I think this little amp is in good health.
Any insight would be appreciated.
Regards,
Analogman
