Thank you for the swift answers in the first round and . . .
AS I am slightly over enthused, I looked at the sketch and thought" Suppose the width internally was 23 7/8ths.. How much difference could it make? ( Could I save a nickel?)
But after just thinking of making lists of ideas and things ( cutsheet, sketchup, labeling parts, buying parts,) for procedural flow, it occurred to me that this (legacy)(?) project is the result a lot of great thinking, expertise , experience and community,
One thing this is not about and never mentioned, is ECONOMY. Its a build not as big and bad as some, but HOLY WOOFAGE, BATMAN . . .
(This site is full of BATMAN types: smart, creative and persistent, willing to fail, etc. like Edison)
So I want to create a document that can make me (or almost anyone) feel things are pretty well idiot-proofed so that proceeding is expertly and clearly detailed, like a BF plan. (my only DIY experience: a good one, its that ITCH thing)
I've only done 3 builds, a mere neophyte. . .
An estimate for building 2 is easily in the $2200-2500 range depending on primarily final finish,. Lets not cheap out on necessary quality.
One shopping list:: 2 UXL MAch 5 18"'s $1,100
This is a question: Which will get the most bang for the buck and or the best long term performance, flexibility, An Inuke4000DSP ($500)
OR a combo of a Beryy EXP4000 and a Minidsp 2x4 way advanced, probably about $550 total
Excuse my naiveté, but since the UXL is rated at 1200 watts, either of these amps is "supposed" to be able to mange that or more at 4 ohms., I just going by the numbers, I have absolutely no other frame of reference. about being "technical"
So far that total is $1700 or so, if you try to stay realistic.
I found really good deal on 6 prong 1/4x20 T-nuts, 7/16's shank, ONLY $223 for a box of 2,000. (needs more research)(ya think?)
Loew's has 3/4 ply, sanded fir for about $40/sheet. Once I work out actual sizes, the answer is keep buying until its all cut . . ., its not about economy but working smart is preferred
Of course BB is to also be considered
How about a section WRT: BREAK-IN: Rum the speaker at __?__volts for __?__ hours using a __?__tone.
I might think that's enough for now so its back to the drawing board.
This stuff is GREAT!
