You would need toclimb into Scott's head for that.

I find the long tail base to be problematic also. They stick out further than my larger 2 ways. I'm also finding that I need to put stabilizer bars at the bottom as they tip over sideways easily with the long base, and don't ask how I know.

yes, they can be tippy - outrigger bars or flat plate approx 14" wide works well

The depth and shape of the rear mouth are entirely functional, ans as I've said before if the footprint of the FH3 or XL is awkward, either the Pensil or Dave's compact floorstander are worth consideration.

A thought to give anyone nightmares. :D

Another question, what are the implications of reducing the depth of the base from 17 inches to 12. The reason i ask is that it give me more flexibility in their room placement
What Dave & Chris said. Major: it's functional, not decorative. If you want to do that, I'd suggest a different design, e.g. their compact floorstander, a pensil (depending on driver) or similar.

I thought that would get your attention. Let me say first that I am sure any shortcomings of these speakers is a direct result of something I have done wrong. That being said, I have to admit I expected a little more. A little history... a few years ago I picked up a pair of Solo 103's at goodwill for 3 bucks. One day I stumbled upon plans for Zigmahornets. I spent very little time and money to throw together a pair and when I fired them up for the first time, my jaw hit the floor. I was obsessed. I couldn't believe that such a natural full sound could be coming from this tiny radio shack speaker. Sure the bass is lacking and I run a sub but the mids and highs are nothing short of magial. Naturally I had to have more. Enter the MK3. I poured over the forums and set out to build a pair. I chose the chp-70 based on recommendations and it's low price. I realize the 7.3 is probably the driver of choice and i'll save my pennies for a pair, but I just gotta believe these can sound better. Where do I start? The highs are terrible and they just seem lifeless. Help me find that "magic" I know is lurking in there.

coopercustoms,

I am guessing that you have the CHP-70.2 - which would have a more "vintage" sound with rolled off highs...

Have you listened to the drivers in free air? How do they sound? How many hours do you have on the drivers?

Also how have you lined/stuffed your FH3?

Sorry, lot of questions - but more info will help folks to give suggestions.

Btw, your build looks very nice - hope forum members can help you find the sound you are looking for.

The CHP70.2 has a top end (top 2 octaves) shelved down 10 dB or so (and a peak just before that). We added a tweeter to it, but it really needs a better XO than i implemented. Scott in his Jennas does use an elaborate XO that is much lower then mine.

I got email from one fellow that removing the dustcaps freed up the HF. (he was looking for phase plugs, i didn't have any, but they are easy enuff to cobble together).I haven't tried it so i don't know.

thanks. Yeah, I made the brass plugs in my ziggys and they made a marked improvement on the highs. I figured I gotta try it on these. also a few coats of mod podge. Ill post results. hate to add a tweeter, kindda ruins it for me.

I'd suggest 1 coat thinned modpodge (do not thin too much)
