Waveform Research Mach 17 loudspeaker

Waveform Research Mach 17 loudspeaker

I first heard the Canadian-made Waveform Research Mach 17 loudspeaker system in New York City at HI-FI '96, <I>Stereophile</I>'s Home Theater & Specialty Audio Show. Another Ontario native, <A HREF="http://www.stereophile.com/interviews/996russell">Chris Russell</A> of Bryston Ltd., had raved to me about their sound. His recommendation sent me outside my assigned reporting area and down to the sixth floor of the Waldorf=Astoria, to dimly lit room 602&mdash;full of <A HREF="http://www.stereophile.com/roomtreatments/215">ASC Tube Traps</A>, amplifiers, cables, and the twin truncated pyramids of the Mach 17s.

subwoofer room management

I have a Paradigm Servo 15 sub which had a muddy integration with my Dynaudio Contour 1.8 floorstanders. I elevated the sub onto 8 number 3 Vibrapods, each with a racket ball resting between the base of the sub and each Vibrapod. My flexible suspended wooden floor was also allowing feedback from the sub to the Rega 25 turntable. The racket ball/Vibrapod suspension cleaned up the sound and eliminated the feedback.

Tuning a port reflex cabinet

Outside of the universal calculations to determine the port length is there any way to measure what Hz the box is actually tuned? For example, if the calculations determine that the box should be tuned at 34Hz is there anyway to measure that other than just sticking the required length port tube in the cabinet? Is Figure 31 pointing me in the right direction?

"21st Century Vinyl" - Two Thumbs Up

Just devoted a couple of hours to Michael Fremer's DVD, and I nearly posted these comment in the Raves section rather than here. If you've enjoyed reading interviews with industry pros in the magazine, you've got to buy this DVD just for the interview with George Marino - a really charming guy and a terrific exchange. I'll play it again some time.

Heat

Drenched in sweat thanks to the charming weather here in New York&#151Oh wait, I forgot, I promised only to bitch about one season which would be winter so let me say I love summer and begin again.
