the model 7 setup with disto, laser jig, Vandertones, etc is a couple of hour job with an assistant and no Margarita.
The model 1 manual also includes an excellent explanation of power dissipation, spl and duty rating...
It is hard enough buying new speakers, let alone older speakers to use as an upgrade
The above subject title about the potential difficult in purchasing an older speaker, that is, a speaker that is at least 10-15 years old (and now discontinued) but garnered very good to excellent reviews when it came to market. I have often seen good reviews and personal recommendations for Linn's Magik 140 speaker and the Joseph Audio RM-25si Signature II. speaker, both approximately in the same or close to the same retail price, but no longer available.
It would be an audiophile's dream to have a small warehouse to store several of these overachievers so as to audition them. Another speaker, I have come across for sale on AG and elsewhere (and is far more expensive) is the Vandersteen Treo, a beautiful looking speaker that reviewed well, but was discontinued in favor of the Treo CT , and now I think the "Vandy" 5a Its main caveat like several of Vandersteen's models is difficulty getting the room placement dialed in as a consequence of the use of first order crossovers. The original Treo (used) would be at the outer limits of my budget,.... but how might the Linn and Joseph Audio speakers mentioned above, measure up in overall value.
