The Anatomy of the Acapella Violon - shocking find
Amfibius- I believe you misunderstood the purpose of the DQLP-1. It's not an EQ, it's a high-pass/low-pass filter that will allow you to drive your woofers with a separate amp. This will free your main amp of the burden of reproducing bass freqs, ... 
Damping factor or watts?
Atmasphere- The URLs that I mentioned above contain sites and papers written by engineers in the fields of audio and electronics. Are we to believe that their understanding of damping factor as it relates to speaker control is wrong,and you are ri... 
Tube amps have a signature sound
Odd ordered harmonics have absolutely nothing to do with loudness or SPLs.( http://www.thewhippinpost.co.uk/glossary-H-M.htm) (http://www.hometheaterhifi.com/primers/the-primers/negative-feedback.html) They WILL give you a massive headache however... 
Tube amps have a signature sound
I've been listening to live music as a sound tech/engineer since the late 70's. My experience has paralleled that of the reviewers in Stereophile, The Absolute Sound, FI, and most other "high-end" rags. Tubed equipment just sounds more like live m... 
Damping factor or watts?
It's interesting how those three different URLs came out with the same "wikipedia" addy in the post! Hlgoh- The main point is: Don't be confused by peoples' opinions. Most only have those and not much in the way of truth. Do the research, and make... 
Damping factor or watts?
While Back EMF is not completely irrelevant in this discussion, I didn't feel it warranted inclusion in the definition. For a better understanding of "damping factor", see these: (http://en.wikipedia.org/wiki/Damping_factor) Particularly pg 1, par... 
Damping factor or watts?
Damping factor is is an amplifier's ability to control a woofer's motion after the drive signal has ceased. For example: if you drive a loudspeaker with a bass drum whack, the woofer's inertia and resonance in the enclosure will cause it to keep m... 
Accidental improvement in performance...cheap
Type in "acoustic foam" on eBay's search bar. There's a Canadian company making Auralex knock-offs(the original is also avaiable there). Their 2" X 24" X 24" squares, and Bass traps(just like the LENRDs) do wonders for room acoustics. They can be ... 
crackling noise at high volume
What destroys tweeters is almost invariably amplifier clipping. The tops of the waveforms are clipped off by a lack of voltage in the power supply, and the result is a squarewave or(almost)DC arriving at the tweeter that fries it. That happens whe... 
Bose 901...really
That's all that Bose ever had going for it: marketing hype. The whole concept is a lie. As a Sound tech: I'm familiar with a lot of music venues. Everyone that I've ever been to that sounded worth a nickel had sound treatment behind and along the ... 
Soundstage...How to determine what's right?
One more thing: Be certain to read the reviews on the VK-D5. Especially the comments on soundstage reproduction! Enjoy! 
Soundstage...How to determine what's right?
Hi Scoly1- Check out this URL(http://www.balanced.com/products/cd/Vk-D5/index.html) for an idea as far as a tubed CD player. It's what I've been using for a few years now. My previous one was a California Audio Labs Alpha/Delta CD player/DAC set-u... 
The Anatomy of the Acapella Violon - shocking find
Here's a bit more support for the solution I've recommended. Read this article:(http://www.sonoris.co.kr/review/reviews/tas/exoticagr-part1.html) There's a DQLP-1 at auction on this site right now. None on eBay. A nice thing about the piece: If fo... 
The Anatomy of the Acapella Violon - shocking find
Hello Amfibius: I didn't read any of the responses, so forgive me if any of this is redundant. Your first thought about connecting the woofers in series- You'd be doubling the impedence seen by the crossover and totally changing the filter frequen... 
Quad 988 how big of room do you need?
Hello Tdanalog- Whatever you may end up using: Type, "acoustic foam" into the searchbar on eBay. There are a number of products in there designed to tune your room against unwanted reflections and control resonances. Auralex panels and LENRD bass ...
