Very true on all accounts! I proposed to EMP a business model like Build a Bear where you can customize your speaker by choosing a series of upgrade options in drivers, crossovers, etc. You then get a speaker with a birth certificate with measurements and a statement they were custom built...

I meant dull in the context of comparing a tonally neutral speaker to a bright one. I have heard many speakers over the years that have an elevated top end that at first listen appear to sound more revealing but overtime very fatiguing and unnatural sounding.

The bottom line is you have to spend a good amount of time with a speaker to ultimately determine if you like how it sounds. A bright/bassy speaker will initially sound better than a neutral speaker in short sighted or blind tests. Try living with a bright speaker over a course of a few...

Power response is typically done anechoic in 10-15deg increments spherically around the speaker. The averaged results are then weighted according to the proportional area of the sphere represented by each measurement. There is a really good article on this I’d love to attach but I haven’t...

I agree. Also just how much sidewall reflection do you really want? It is definitely a balancing act. It's funny. Years ago when I was setting up my theater system in my family room, (long before Toole's book came out), I decided to put absorption on the sidewalls b/c classically that was...

Emotiva takes its time to design quality crossovers that don't display any nasty low impedance dips and they employ good parts and layout. Vance Dickinson does their crossover work and he is considered a legend in the field.

Sidewall reflections are beneficial NOT detrimental. I agree most people stick their couches against the backwall which is bad for smooth bass response and a realistic surround field.

Early reflections dominate in small rooms as per Dr. Floyd Toole's extensive research. Of course a speaker exhibiting a smooth and even power response will also likely produce good early reflections since its off axis response is consistent.

DS-21; I had Floyd Toole look over this thread personally and here is what he had to say: As you can see, you are not properly presenting and interpreting his research. SFM is a tool to help open up more placement flexibility but it doesn't negate proper positioning of the subs in the room...

I installed this EMP sub for a friend in his bedroom system using a pair of EMP e55Ti towers. The combo produced excellent results with plenty of deep and tight bass for music. It's a great deal. Merry XMAS to you!

DS-21; If you have Dr. Floyd Toole's book "Sound Reproduction", I suggest you read Chapter 13. This chapter is very clear about optimal positioning of subs in a room to smooth out bass response. As far as my understanding of ARCOS & SFM, the system will actually measure the room and suggest...

That is very true and hence reaffirms my point about averaging multiple measurements. I do agree that we typically want to correct only low Q bass problems but you still need high resolution data to accurately do this. I make a series of closely spaced measurements and use LMS which can apply...

1. Don't trust Audyssey. Try getting the bass to sound right without it first. 2. Marantz has bass level settings per surround mode (ie. 2CH, 7CH, PLIIX, etc). I found this out the hard way myself. Make sure the sub level is set where you want it for each of those modes. 3. Experiment with...

You like to quote Dr. Floyd Toole's book but did you actually read it? I doubt you did else you wouldn't be making the argument that measuring with 1/3rd octave resolution is "enough". I need not reinvent the wheel when masters like Floyd Toole have already done so. If you really want to know...

Velodyne has always been very vague about this. They claim they purposely smooth the measurements to 1/3rd octave to make it easier for the average consumer to understand. Personally I believe their measurement system is simply limited in resolution to take anything better than 1/3rd octave...

The Audyssey measurement displays from their system is equally if not more useless than the measurement display of the SMS-1. The Audyssey displayed measurements are theoretical so actually they are worse. The reality is consumers like to see smooth graphs. As Colonel Jessup used to say "You...

Wow there is a lot if misinformation in this post but I will try to address the main issues here. 1/3 octave is NOT sufficient for doing any sort of room correction or analysis. The SMS-1 system is more like 1 octave than it is 1/3rd, but lets assume its 1/3rd for the moment. Taking a high...

The SMS-1 has never been an accurate measuring device. It's a crude approximated measurement system which I've noted in our SMS-1 review and my DD15+ review. I've even written about this in an article: Audio Measurements: The Useful vs. the Bogus in Consumer Audio — Reviews and News...

The Paradigm sub2 review will not be completed or published till 2012. Thus it will be a candidate for the 2012 award. I'm quite certain if it wins, some keyboard commando will point out for the same price one could purchase 8 Epik subwoofers though ;)

Axiom does have a history of changing products based on our review criticism. With the on-walls, I found leakage issues at low F and they changed the gasket to fix it. I found many issues with the A1400-8 and they....discontinued it :( They are developing a new center channel with a WTMW...
