no- there's no reason why it wouldn't make sense NOT to give 'er a crack-- at worst, i wouldn't like the results!i guess the difficult part really is sorting out measurement vs. hearing- tricky at best! trying to assemble sense from possi...

romy- i have resisted using RTA for the very reasons you're citing-- learning to read the visual data, as well as methods of how to get it accurately, are as equally time consuming as any other pursuit in audio. anyone can be a reade...

thanks for the responses doc and romy-much food for thought- but what i'm thinking, or at least extrapolating from what you're saying is that the possibility exists that i AM measuring what i think im' measuring.i have a good friend who is very...

hey romy and all-i recently came across a strange phenomenon (to me.. maybe not to everyone else!).I just started using RTA as a method of evaluating my results with my own 2 way speaker system, and I'm finding that I'm ending up liking the sound of ...

Romy-In this thread, you previously said--12) If a
filter requires a phase inversion then it is preferable to flood
crossover point with amplitude and do not invert phase.What exactly do you mean by this and how's it work?thanks-d....

what a great idea-- i never really thought of a sort of 'low pass bypass' inductor of sorts?! i'd always assumed that inductance was similar to capacitance in that regard-- the more you add, the more you get-- but hadn't thought about the...
|
|
hm..lots of interesting information to chew on, and by and large, i've had similar experiences with first order crossovers on bass drivers .. this being my experience with a full range amp, and a two way system-- which is a far different critter than...

yep-- i always measure first to get as close as i can get to a matched set (within a % or 2 at least!). luckily, for this application, i got 4 extras.. so i should be able to get close, and for all the sub- 1uF caps i have around for all the ot...
|
|
it must've been my time-- i just tripped across a batch of 20 1uF vitamin q 100vdc caps for $4!it's a lot of soldering... but for $4? i bit...thanks all!d....
|
|
hmm..well.. duelunds.. they ARE mortgage lifters! i think i'd be more likely to hunt down old vitamin q's for a few months while settling though... i did try solens-- and while they were a revelation by comparison to absurdly overrated voltage...
|
|
yep-- i could tell from the minute i stuck them in they were a no go... the foil is WAY too thick.i've used what i've been able to track down via ebay, and other nefarious means-- so those came in a lot of other lower voltage caps-- all in the 1-200v...

mixing those two seems to bring out some of the best of both, so far!the capacitor (or two, as the case may be) is an 8uF combo- 2 4uF caps-- one VQ, one hovland musicap. i HAVE 8uF of vitamin q, but unfortunately, one 4uF is a 400VAC, th...

|
heres a question for the lot of you-due to general lack of many available capacitors in my shop-- i recently mixed both film AND oil caps to pull together a necessary value for a passive crossover. the GOOD of it, is that it takes away some of ...
|
|
hey jessie-I've wondered the same thing-- and the more i end up twiddling around with it, the more I think it really either comes down to good measurements, or good listening! And in fact.. probably both in conjunction!I have a small 2 wa...
|
|
now THAT is the kind of instruction in critical listening that gives you some real guideposts for making your system sound right! romy, i believe you have honestly set a new standard... i have a 2 way system, so i can't use the exact instr...
|
|
speaking what you really think is often percieved as arrogance.. so i wouldn't worry about that, and i wouldn't take offense at somebody who's worked on their system extensively (even with similar drivers) speaking their mind. kinda the point o...
|
|
fair enough- you're absolutely right, i didn't!it's difficult to get that perspective on sonics without legitimate guideposts-- even with a lifetime of playing and recording music, it's difficult to know what the parameters of recorded sound ar...
|
|
the sad truth was the space, the finite funds, and the available bms pucks! the sad truth also, i suppose,the lack of available, and sensitive horn users to bounce off of!i could probably see what your dislike of the bms stems from-- i tried to...
|
|
agh..well.. i can see that you'd never be over for a beer and listen session, romy! not that i wouldn't invite a curmudgeon such as yourself.. but my own system might not make the cut!i just finished off a little 2 way bms/altec system (and i d...
|
|
i definitely see what you're saying there.. but i do wonder if it has more to do with the economics and the powers that be than a full on case of negligence. most sound engineers-- or at least those i've known (and not the bastard species of fa...
|
|
i certainly know a lot of 'audiophiles' with a vast array of gear-- some good, some bad -- but i think there are a variety of reasons people are so confused about what constitutes good sound.one of the most heinous- outside public opinion- ...
