The Smaller Advent Loudspeaker

I am curious to see what happens with these as I have a pair of S.A.s I refoamed that are sitting around doing nuthin'. :)
 
O.K., I'll give them priority.

The woofs are refoamed, but the queue is huge.

[Maybe if I put up a poll...? :tongue: ]

Truthfully, that ain't too damn bad of a response curve. I've seen "high-end" speakers that measured worse! On axis, they're +-3.5dB from 90 Hz and up...

In fact, with a little notch-filter (or crossover tweak) at 1KHz, they'd be remarkably flat.

And they do really measure better with the grille on! I try to tell people...

Regards,
Gordon.
 
I, for one, really like the Small Advent the way it is, and better than the OLA.
I don't get the perception that a bright speaker is better.

Don't forget, the Advent speakers were "Cash Cows" to fund his R&D for the VideoBeam.

Not a criticism of the speakers, but an explanation for their production.

The 2k "suckout" is a measurement artifact. It is caused by the crossover between the drivers and the directional pick up of the measuring microphone.

Maybe a dumb question...but do my Advent/1s count as "smaller Advents"?
Thanks

Well, they are a smaller Advent and they were meant to replace the original "Smaller Advent" but the lowest octave is hurting with them because the same drivers were used as in the New Advent Loudspeaker only in a smaller box.

The original Smaller Advents have customized woofers so the lowest octave is preserved.

We determined in earlier Large Advent studies that the "fried egg" tweeter interferes with itself and the cabinet recesses and edges producing a conspicuous notch in the response. The grille serves to mitigate the problem, in part, at least, acting as the actual "baffle" at a forward plane. In further substantiation of this thesis, here is the tweeter playing alone without any interference from the woofer:

Compare to Atkinson's measurements of the influence of the grille in the Stereophile review linked at #16, above.

[Measurement mics are omni-directional, BTW.... :yes: ]
