Help Me Build Crites CS-1 Speakers - Page 3

hmm....i am thinking maybe put some gorilla glue on it to keep it flat?

is this the bondo type you're talking about nyt?

do i need to cut the ripped piece off first? and then fill it with the wood (bondo) filler?

right now, the ripped piece is sticking out too much.

thanks, i guess this is the one i want?

elmer's natural wood filler?

guys, i heard some folks using dampening material on their horns and woofers. is this necessary? if so, what materials/products?

thanks

thanks guys, i've decided to live with the defect.

it seems a bit of extra work just to fix it. i took it as a "lesson learned" for the next cab build.

almost ready. this is after a few rounds of amber shellac and sanding.

you can see some of the cracks/chips near the edges.

i kinda like the clear shellac more than this amber. i know it darkens the woods, but it just doesn't seem to bring out the grains as nicely as the clear shellac.

just need to add some bracing and damping materials, and it's ready for drivers to go in.

yes, i thought about filling up those chips but just too darn lazy. and it doesn't bother me that much. i am not a perfectionist at all.

now, i need to find where to get some polyester batting to line up the internal.

yeah, i got lazy this time. i usually have a piece of spare wood between the clamp and the cab.

and one speaker is done. sounds pretty darn good in mono.

and here it is in the room, on top of my diy mfw-15 sub.

a few more better shots......

yup, i have virtually no staining skills as you can see overlaps and varied light/dark areas.

i sanded 220, 320, and 400 grits after each coat of shellac. it's very smooth, but could use a few more coats/sandings.

they sounded really nice, the vocals/highs were very clear. i think i need to listen to the mid bass a bit more as it seems a bit lacking. maybe it needs to break in a little, or it got overpowered by the 15" sub. i have only listened to it for about an hour.

speaker #2 is being glued/clamped!

one can almost never have enough clamps.

i really don't know, since i have not heard either an ewave or a 4pi. i'll let the experts chime in.

but i do know that my next build will be 3 4pi for the front stage.

per parham's white paper.

"....meaning the cross-section of the horn is exponentially proportional to its length. These have long, narrow throats with ever expanding mouths. The advantage of this kind of horn is it tends to have large bandwidth, providing a good acoustic load at both high and low frequency. One can expect an exponential horn to provide adequate SPL, even response and low distortion over its passband.
The problem with an exponential horn is it tends to beam at high frequencies. As a result, only listeners that are directly in front of the speaker will hear high frequencies. ......"

both speakers are done!

while they sounded nice, i ran some tests and it's a bit surprising.

looks like i am falling off at around 10khz. i was expecting this not to fall off unitl around 18khz.

this is the d220ti 16 ohm. yes i did "toe in" the speakers.

i also try to push them against the corners, as well as bringing them forth about a feet from the walls.
