Aww Jeez Not This Shit Again Meme

I know this is idiotic but I have honest questions near incremental gains. If I am to advance I need to understant these things - I appreciate your patience - really!

Let'southward dismiss the obvious - I know I'yard non measuring yet (I have SW but the Wallin jig is taking more fourth dimension to get to than I thought! )

In whatsoever case. Y'all know what I'yard up to just hither's my question. (those who don't can catch up on my previous posts about my project so I don't waste the peoples space and fourth dimension).

I chose my drivers based on an established blueprint - they're not exactly the aforementioned (the tweeters are different) but the manufacturers charts are virtually identical - the woofers (Extremis) are extremely flat regarding impedence - the mids (CSSwr-125) are the same - and the Dayton silky virtually the aforementioned equally the established blueprint requirement. The cab is to spec.

You already know I'm running them on a PE Dayton XO at 700/5600.

I already hear that the mids are as well hot considering the design calls for a 3/4000'ish XO point instead of my canned 5600 but I'll ready that later.

Those points are way in the middle of each drivers range, nowhere near the nasty curl-off and/or suspension-up (according to the manufacturers charts).

I have no Zobel still because (here'south the catch) the Extremis impedence curve is soooo apartment - why do I demand information technology?

Next - and here's the signal of this post -

When you choose XO points for whatever reason (peradventure measurement, mayhap charts, or your ain preference) Please tell me what else that XO will practice for you (aside from LPad and Zobel)....?

Believe it or not I've read piles of XO blueprint stuff - I use Win ISD and XOCalc, etc - I know it seems unlikely - but I fail to see the actress magic (aside from component choice - and all the benefits therein) that these straight-forward calculations yield. And yes I understand the impedence curve.

I am not discounting the fine art of voicing (something I am years away from) just as to matching commercial loudspeakers - is it actually relevant?

One time again, I beg your patience, I have equipment on order and am edifice my measurement gear but for now - I accept to say the following.

If y'all PAY Attending, choose drivers that match a given canned XO and you build the right-sized cab - why should the result suck?

I have spent hours at Tweeter (a Usa based HIFI joint) - and a number of esoteric HIFI dealers and have found that my canned, knock-off works okay - non perfect by any means - just worth every dime of the 2 or three grand the retailers want.

So, here's the meat of the consequence. If I go shut - just how close do I need to be? Where does the indicate of diminishing returns come? How much ameliorate can I get with a given design if the XO points lucifer the curves and the driver efficiencies are real close (given that cab specs are on the beam).

Am I just deluded?

I have to admit I have a hard time ownership that conclusion.

Who knows, maybe I'm partially deaf. Maybe dense too...

Tom
