I need help from GMA Europa owners
Thanks- let me know if particular cones under the Europas do any good. Always curious.The Europa marble is quite thick at the bottom, and it would be easy enough to put in four (three?) dimples with a drill bit (1/8" diameter probably) to locate t... 
I need help from GMA Europa owners
Hi Rich- glad to hear you like the Europas.Mdf stands, even with sand filling, have a "fuzzy" resonance in the particles of the wood themselves. A stethoscope would reveal this as stimulated by tones in the AM radio/nasal voice range.If you are go... 
Current Trends in multi thousand dollar speakers
In my experience, virtually all the points made above are pretty right on. However, I would like note two reasons for the skewed (measurable and/or audible) tone balances.I believe most tone-balance/cabinet-tuning decisions are made to offset the ... 
Tube amp and speaker impedence matching
Europas are 4 to 5 Ohms for most of the audible band- no lower than 4 Ohms. Very resistive load, and very little back-emf from them makes your power just fine, in my experience- loud enough to have to turn it down to converse in any room smaller t... 
Subwoofer Blending
The very best subwoofer blending (for a mono sub or for stereo subs) comes from using a combination of crossover slopes that were developed from theory (not by me) and first proven in the early eighties in pro-sound installs. The THX company has t... 
Woofer on Top Speakers
Tweeter placed under the woofer often puts it farther from the ear than when it's in the "on top" placement, to make up for the fact that the woofer's acoustic center lies farther away- down near the voice coil-cone junction. Placing the woofer on... 
Do most manu. buy or build their x-overs?
I do not know of a "high-end" speaker manufacturer who does not design their own crossovers- this would include Enregy, B&W, etc. They may contract to have each particular model's boards built, say in China, out of certain brands and certain t... 
A few questions for Green Mountain Europa owners
Thanks for the comments guys!M2500tvr- contact me about your layout, or request a new copy via e-mail of the Europa manual. The speakers are too far apart, unless there is something about your room we should discuss (I know we've spoken). Try the ... 
A few questions for Green Mountain Europa owners
Thanks for the comments and compliments guys!Lou- the parts we use are stated on our miniscule website, and as Tennis Junky said- an Aurasound woofer (not fancy looking- resembles an old ADS woofer), a Morel dome, a SonicCap capacitor for the twee... 
A few questions for Green Mountain Europa owners
Thanks Phasecorrect-I must point that we hear the Europas reveal poor cables (interconnects), which too often make a sound (a grunge if you will) all of us interpret as poor recordings or poor CD players. With the finer interconnects, you would he... 
Green Mountain Sub??
Rhl Jazz-The sub you have is the Continuum 12SW. The box is not MDF but an industrial-grade particle board that most cabinetmakers don't like to work with, because it is much harder to cut and shape than MDF. MDF is a weak wood, and to make it str... 
Revel Studios for half price?
For a 10" three-way, we've made the Continuum 1.5 since 2000. It has several times the parts cost of the C-1, with better cast marble visually and acoustically, and an even stronger and quieter (more difficult to make) woofer cabinet. $4995/pair i... 
Revel Studios for half price?
Thanks for your comments, Ritteri.From what you said about the image shifting with power levels, I believe an employee (no longer with us) must have wired the L-pad resistors to mid and tweeter "backwards", which would produce some strange results... 
Revel Studios for half price?
Ritteri-You say,"We put a few of the older Continuum's up on an RTA. We could never match the response curve between ANY single unit under identical circumstances or even get em close."We do indeed match to tight tolerances as stated above- always...
