I live in a large cement room...
I stand by my statements pertaining to the non-linearities of foam. This even applies to "professional grade acoustic foam". If you don't believe me, read what one of the foremost experts in the acoustic industry has to say: RPG.http://www.audioad... 
Has anyone listened to Legacy speakers?
Muller, as i told you when i briefly listened to your system, your speakers sounded FAR better to me than the Legacy 1's or Classic's. I was being completely honest and sincere in those statements. I hope that you took them as so.Other than that, ... 
I am Not hurting anything right ??
Try reading Jon Risch's website regarding the "technicalese" on bi-wiring. As to bi-wiring feeding the same signal to both sets of terminals, that is not necessarily so. On a speaker that is TRULY designed to be bi-wired, the two sections are comp... 
DIY Subwoofer
Here is a comparison of several different drivers in different alignments. http://www.zebra.net/~mvance/projects/bass/Twelves/index.htmlWhen looking at any woofer spec's, ALWAYS take a look at the impedance at resonance. The higher the impedance, ... 
How many dedicated lines?
You can do a dedicated "ground" for your audio system so long as EVERYTHING connected to it is on the same ground. In other words, using a dedicated ground for just the amps and then having your sources, preamp, etc... tied into the common house g... 
John Dunlavy On "Cable Nonsense"
Grungle, do a simple test. Simply compare some standard 12 gauge "monster" type speaker wire to some Kimber 4PR in YOUR system. There should be no major difference as they are both reasonable gauge, low resistance conductors. You can do this regar... 
Has anyone listened to Legacy speakers?
Trelja, could you tell us how you REALLY feel ??? : )No, i have never worked on any Focus'. I have been told that they use some very low grade wiring internally though. I do know that some of the wiring that they used to use had REAL problems with... 
Going Topless
Bob & Plato bring up some interesting points. On top of what they stated about the weight of a steel chassis, one also has to think about rigidity and overall strength. When one looks at the amount of posts on the web about goods damaged in sh... 
System sounds different, depending...
You might want to invest in a small meter that can monitor your line voltage. If you are experiencing differences in line voltage, your system CAN change performance levels. Depending on how your amp / preamp is designed (unregulated, loosely regu... 
Has anyone listened to Legacy speakers?
Lak has probably got the two best models that they build ( in my opinion ). The Studio uses the same "mid-woofer" that the highly reviewed ( and excellent sounding ) $4000+ two way Legend mini-monitors use. As to the Signature III's, they use a co... 
Going Topless
Removing the lids on components can have a DRASTIC effect sometimes. Besides tubes receiving more direct stimuli via vibration transmitted through the air with the covers removed, circuit stability may also be effected. While most of my experience... 
John Dunlavy On "Cable Nonsense"
The problem with blind tests is that they are typically conducted in less than familiar surroundings. As such, one may not be comfortable in test setting. They are also not allowed to familiarize themselves with the subtle timing, tonal or spatial... 
John Dunlavy On "Cable Nonsense"
THAT is the VERY reason that he got his ass "bbq'ed" over on the Asylum. Saying one thing and doing another is what made him the "poster boy" for hypocrisy on this subject. Sean> 
Advice- wiring for dedicated sound room
Glen, thanks for sharing your info. It's always good to hear from a professional. I would like to share some of my findings in regards to some of your statements though.As to your comments about #12 being fine for runs up to 150', i would disagree... 
Best 2 ch. speaker placement algorithm.
Jdwek's directions are right in the ballpark. I would simply add that using a solo singer with your preamp set to mono ( if possible ) is a GREAT way to determine the width of the speakers. When you no longer have a central image and are hearing i...
