Pioneer HPM-100's or 900's. Gazillions of Bart Locanthi fans can't be wrong.
Well you can get the 508, and 510 with 2 X 10 inch carbon fiber woofer since March 1. Altec has reissued them see the Legacy section of thier website. The 508 and 510, I have a pair of both are clean, clear great speakers. The "dead" sound of the carbon fiber gives wonderful bass without distortion.
I am a quite a bit late posting but I just came across this discussion while researching the Altec Lansing Legacy series speakers. My inquiery is about the 510S & 508S models: How do they compare to speakers of today, regarding engineering design, parts & quality, sound, etc. My questions, obviously, are for you, msullivan. Beings it is not possible to audition these speakers prior to purchase I'd like get as many opinions as possible. If you know of any site I can go to and find more info please let me know. Thanks. Mike
