The Anthology Speaker Kit by Curt Campbell and Jim Holtz
The design goal
I established for this project was to come as close as possible to the full-sized Statements II in overall performance but lower costs and offer a different driver configuration that would allow a less
imposing cabinet for better WAF. I had no interest in designing yet another Statements variation but rather establishing a new design that offers top-notch performance through careful driver selection with low distortion,
excellent midrange for all types of music, and exceptional dynamic range for home theater use.
Cymbals sound like cymbals and the sound of triangles floats in the air. The highs are open and airy with great off-axis dispersion. The 22TFF has excellent sound quality that realistically reproduces the original
performance. It greatly exceeded my expectations for an affordably priced tweeter.
Midrange purity is a top priority in the Anthology’s. Curt and I tested several drivers in the price range we were shooting for and settled on SB Acoustics SB15 coated paper drivers as the best candidate for the job.
They are ultra-low distortion and rival much more expensive 5” drivers for sound quality. This is the latest version of the Anthology’s that includes the updated mid ranges – SB15RRX2C-30-8. The crossover network was also tweaked for accuracy.
How Do They Sound?
If you are in love with detail, realism, and a big realistic soundstage like I am, the Anthology’s won’t disappoint you. They’re smooth, detailed, and dynamic with the right amount of bite to realistically recreate
the performance you’re listening to. The Anthology’s will be compared to the various Statements and the Finalists since they are all open-back designs. The Anthology’s are not designed to replace any of them but rather to offer an additional lower cost and smaller profile option with big dynamic performance and a stellar midrange. Their reduced height offers WAF benefits that make it easier to build just one more speaker! Take your pick and enjoy!
“I just wanted to tell you that I built the Anthologies from your drivers/crossover kit. The first time I heard them my jaw hit the floor, like WOW! And they keep getting better and better as they break in! They have really renewed my love affair with music.” Terry H.
