DIY SEOS for HT upgrade - Page 7

Actually resumed my delta-light project this weekend.

Got the stands duratexed and assembled


Mounted the speakers to the stands, pre-drilled holes for drivers, and duratexed


Tinkered around with crossover layout (which I hope to solder up tonight)

Thanks Sibuna!
They were mounted flush (screwed and glued)

Thanks - good point!
I'm also going to increase the distance between them

First XO finished, not the prettiest, however....
(2nd one should be prettier)

Thanks!
That graphic is most helpful! Will be moving that center coil to the bottom edge of the board tomorrow night

drewmc,

Thanks - good suggestion!
If I can't find the room on the "bottom", your suggestion will be employed

OK reconfigured the board by moving that coil to the lower righthand corner (bottom left on this photo)
drewmc/mrkazador - Thanks for the suggestions!


Next two shots are self-explanatory, used Velcro to mount the XO boards (and a connector for easy removal)




Ready to mount drivers and a listening test

Sorry about the disoriented photos - the image rotate function went bezerk on my photo-bucket account

With the exception of the custom logos; the Deltalights are finished. Moving them into the theater now.

Photos and listening first-impressions tomorrow!

OK with the exception of logo emblems in the lower corners, and some REW comparison measurements; I am done !!!


Over the last 2 days; watched one movie, and 2 hours of listening to some hi-rez 5.1 music;
I am very happy - Thank You to all the SEOS gang, especially Erich, Bwaslo, drewmc, and numerous others!

Listening comparison is against my Klipsch RF35s (one is resting in the front right corner, for future measurement comparisons). The most obvious difference (verified by my 18year old with better ears), is that the sweet spot now spans across all 4 seats, previous "sweet spot" with the Klipsch 35s was the middle two seats. I currently have them toed-in by 40 degrees. Also when listening to instrumentals and percussion; I am pretty sure I am hearing much more detail. Mid range seems punchier. Other observations; the stands are a love it hate it proposition. My wife dislikes them - but hey it's a man-cave

Drewmc,
Good point, I think those bases are what my wife likes the least!
Hmm - may have to look into some kind of "stone-looking" finish

I hope to make some REW measurements soon. However; I believe they will start rolling-off at 70hz

As promised I finally got reacquainted with REW, after an 18mo hiatus. I say this; to ask for your REW forgiveness in advance
Also; does anyone know of a slick way to post REW graphs; instead of my "screen-shot/cut/paste" technique? The following graphs were made indoors. Unfortunately; most of the nulls and peaks between 175 Hz and 1.7Khz are known room issues (the exact source and remedies is an on-going project). All measurements were made with my AVR bypassed, my sound card output was driving the test speaker directly thru my MM900 amplifier. In other words: no Audysey controls, no crossover, no sub-woofers, no processing. Measurements also made with the mic. about 30" directly in front and at the midpoint of the baffle face. Also used 1/6 smoothing.


The first comparison is Big Mal (in blue) under the screen against the front wall.
As compared to a Klipsch RC7 that is buried in mineral wool in an overhead soffit.



The 2nd comparison is a Deltalight 2512/SEOS12-360 (in red)
As compared to a Klipsch RF35.
Both of these were made with the speakers about 2' forward of the front corners of my theater.
