My pleasure.... I hope i can finally be of some use to someone here!
Firstly, acoustics is its own black art, with as much BS, opinions, experts and as many rabbit holes as a conspiracy site...lol
And secondly I am no expert, I just have a few insights that may help out, 50% of people will say BS, the other 50% will say savior, but the main
thing is that im not selling anything so have no motivation other than the help aspect.
1) In relation to the graph... The B&Ws appear a little 'flatter' in response overall, as the Grado has those two peaks at 7500hz and 10k, which
strangely enough I would have thought would have sounded brighter, although the b&ws are a bit higher around 3k and significantly higher above 15k,
but one persons 'brighter' may be anothers 'shimmer'. A bit of a concern is the grados peakiness around 75 hz, this could be a concern as power-line
frequency is at 50/60 hz and the last thing u would want to introduce or enhance is powerline hum.
Things to note here are... the diffuse field eq can introduce a bias, and the graph is limited to 20-20k. peaky response down low can affect the
overall sound as it 'drains' the driver and may introduce harmonics, and peaks above 20k can give you ultrasonic fatigue ( you cant actually hear it
as such, but there is still power being delivered)
Also dont forget that as we age, we lose sensitivity to both bass response and treble response (inverted U shape in relation to response graphs) and
we tend to become more sensitive to hi end fatigue.
Also dont forget about the impedence of the headphones, that will influence the dynamics and dampening, and also the sensitivity, that will affect the
overall 'loudness' when compared to another headphone. (i wont go into phase issues etc here)
Here is a link to a fairly good assessment of the grado.... (www.innerfidelity.com...
) more graphs that all interplay with
each other... but then trying to find some info like this on the b&Ws has been fruitless. Hard to compare oranges and lemons so to speak.
2) Definiately, in my opinion, cans are superior when it comes to 'mastering' as the dynamics of a room (and speakers) are negated. You can actually
'feel inside' the music like you say, and not be influenced too much by external noise. Also most headphones will give a much higher transient
response (i.e. how hard and fast that kick drum kicks) as there is less momentum in small drivers, think of those small little 40mm drivers in the
B&W's compared to a 8/10/12 inch loudspeaker driver (sorry for metric/imperial crossover but thats generally the terminology given the applications)
and the respective masses/coil size etc. And because those little drivers are less than 5cm from your ears, the need for huge drivers moving huge
amounts of air for bass is negated. ( still the bigger the driver the better the bass holds true) Another thing is that loudspeakers will generally be
a 2/3 way, that is woofer, mid and tweeter, and all the associated crossover and phase issues, whereas headphones are generally a full range driver.
(which can have its own issues of course) I have some in-ear headphones that are three way yet can fit in your ear.
3) Reviewing on different speakers is great, and i guess the better the mastering, the more universally good sounding across the types of speakers. I
have three (at least) sets of speakers set up in the studio control room , and can switch them independantly or together to get an idea of how a mix
would sound in the 'real world - whatever that may be..lol)
(yamaha msp3 and yam ns10s for the lower end, some fairly average Alesis M1 Mk2s for boom box kinda stuff, and my beautiful TDL studio 1 transmission
line speakers for the top end) i can also hook into the studio live area PA speakers if i need to go rave levels etc. (also some B&W 602's plus all
the live stuff...)
I believe NEVER worry about how your mix sounds in a car, too many influences... background noise, body size, engine noise, alternator noise both
physically and electronically, badly positioned speakers, crap speakers, really bad amplifiers, boom box mentality etc etc...etc too many
4) Dont get rid of your dads old rig, someday, sometime you will hook them up and maybe even find your musical nirvana, or at least have another piece
of kit to try your mixes thru. Dont get me wrong, some of the old cheap stuff sounded horrid, but i would always like the sound of a good solid well
made (and maintained) 60'sor 70's hi fi setup.
I guess what i was originally trying to say is that without lab/studio grade analog equipment and signal path, that at the end of the day... if it
sounds good to you, and you are enjoying what you are doing, well... thats all that really matters.
I hope I did not take over this thread so feel free to PM me if I may be of any further assistance.
