Separation anxiety a factor?
Yamaha, mine have great separation, no anxiety here.
Played around a bit with stuffing the ports with a rolled up micro fiber wash cloth. Tight fit and substantial change in sound so it's doing something. Definitely a move in the "east coast" direction. Sounds better with some recordings given my less than stellar normal location for the Indignias (utility room cabinet top).
Holly Cole's Temptation (tube mikes and one of the best recordings I've heard) has cuts that sound better stuffed and others that sound best unstuffed.
Need some more time to play with them to get a handle on what I'm hearing. So little time, so many variables.

Damn, Zilch, I have been planning to cop a listen to the Indignia's when we deliver your Baronet clones.
Aw, Please????
Last day of special pricing on the drivers for now, folks.
Git 'er done.... :yes:

Got 'er done this mornin':yes:
I did not buy any cab parts... that's up to my 13-yr old son who will get the "dignity" of having them in his room when we're done. Hoping to find dimensions that will accommodate having both drivers and the port all in line with the duct at the bottom and still have clearance for 8" of duct front-to-back, and still have less than .4 cuFt volume. Don't even know yet if that's possible.
Just back from a 5 day mini vacation in the north woods of Wisconsin. Brought my Indignias with an Accurian. My Super T amp does not have enough power to make them sing.
Played them lots just in front of an open 2 car garage aimed out to the "out of doors." Surprisingly good sound and amazing bass. A pretty savvy audio crowd was impressed and 3 people want me to build them a pair.
Even more highly recommended than before. They truly are overachievers.
BTW, the wild hammered copper color of my pair was a hit with our hostess who has a good eye for design.

Karma Indignia V3.5 Crossover:
V3.5 crossover fits neatly on a 3" x 6" board.
I was able to make all connections except common (black) using just the component leads plus four solder terminals for the driver wires.
Layout prints slightly oversize on my printer. Resize to 6" x 3" for use as drill template.

You may want to think that baffle layout through a bit more.
While there is certainly nothing sacred about the "standard" layout we developed here having the tweeter offset 1/2" from the centerline, that does provide different distances from the tweeter to the cabinet edges, reducing reinforcement of edge diffraction.
Further, it "tilts" the plane of time alignment that small amount, allowing an optimum amount of toe-in to be found for varied listening heights, as described above.
If I were designing a vertical-in-line layout, I might be looking at a pair of smaller (1", say) ports in the front bottom or top corners, or a single rear or bottom port.... :yes:

Thanks, Z... that is good to know.
I was more-or-less taking a look at my Focal speakers which are about the same size, maybe a little bigger, but they have inverted domes & a little aluminum waveguide surrounding the tweeter. Perhaps the designers had cabinet diffraction in mind... I'll post pics later today.
My daughter announced she wants me to build a pair for her so she can paint one turquoise and the other purple for her dorm room. To entice me to build them, she even offered to split the cost with me. This means she's very serious.
I'm hoping someone (with appropriate tools) will step up to offer the flats so more will try them out. I will be trying to cut the next pair myself with a circular saw. While I had the MDF used in my first pair cut at Home Depot on a panel saw, I was surprised at how much the dimensions were off.
Cutting the baffle is the hardest part and while mine resemble each other, they certainly aren't mirror image identical. Regardless, they sound fantastic.
I hooked them up to my old Sherwood S8900A last night (solid 60W of power) and watched the Olympics with them. They love power and I think this is a great combo.
Prior to that, I reconfirmed my initial comparison of the Indignias with a pair of stock Insignias on my hybrid integrated McIntosh MA230. Still no contest, Indignias win the gold. Similar outcome with the Indignias versus a pair of bypass capped EPI 70Cs.
I've also been stuffing the port periodically to see if I like that better. I think Zilch is right, locating them near the walls they sound more natural stuffed but you lose some of the immediacy.
Just to see how good the Indignias are, I compared them to my bypass capped Genesis Model 10s via the 30W MA230. (http://www.humanspeakers.com/genesis/gen10.htm) Things got more interesting but I would summarize by saying the Indignias were better balanced and have more/better mids. While they go lower, it is not as controlled sounding unstuffed. On some material I would prefer Indignias, while on other cuts I preferred the Genesis and their startling clarity (1" inverted dome tweeter). Surprisingly, while the Indignias image like a SOB, I believe the much larger Genesis actually image better.
Thank goodness there was no clear winner. Now I have to keep them both.

We're gonna have to sweet-talk an AKer with the requisite equipment and skills into making up some.
I have a pair of the "Factory" baffles I can send for them to use as models.... :yes:
