Re: My new project (yet to be named)

craig, those are looking real nice. you have a lot of patience. will be nice to hear them at iowa if not before.
those clamps look familiar. im guessing you have a harbor frieght near too.

Yup, China Boat, I mean Harbor Freight. Can't beat them when they were only about $4 a piece :D

Just a few more pics:

I had to take one more inside picture before the front and back get glued on (some of the hardest work is inside and hidden forever :p)



Wow that Gorilla Glue is some weird stuff. Almost like expanding foam. Here is a picture of the T-nuts glued in place:



The 1.5" thick baffles are now permanently attached:

I took notice of the Overnight Sensations in the background in the last pic. Next time I see Paul Carmody, I'll need to congratulate him on being freakin' everywhere.

Re: My new project (yet to be named)

I like the attention to detail by rounding over the edges on the internal braces... The back baffle plate is nice too. I may steel that on my current build...

Keep the pics coming...

Don't squeeze those orange handled clamps very hard. I've ruined 3 of the eight I got when they were on sale last time working on my last project. And I wasn't really bearing down on them.

They are all metal except for the squeeze handle. An 1/8th inch pair of nubs on the inside is all they use to x-fer the force. Too bad.

Good looking build!

Re: My new project (yet to be named)

Just a few more pictures of my latest progress:

Both rear panels are now firmly glued on:



And here are the adjustable ports epoxied to the back side of the flanges:



This is how they will fit the on the back panel. They still need to be flush trimmed and rounded over:



This is the beginings of my crossover boards:

Flush trimmed and round-overred the ports/flanges:



Covered with a little rattle can black:

Re: My new project (yet to be named)

craig, what will you use these for? what will power them?

Re: My new project (yet to be named)

Here's what way too many late night hours of playing with PCD yielded:


That lift in the top octave shouldn't bother me much as I have lost a lot of that hearing range due to open headers and way too much car audio thump back in the day!!! My daughter and wife, however, might not like it.

A little top octave lift is fine off axis anyway. Gives more "air". Looks good and coherent. Good driver choice, They look great so far! I have no doubts about this one :D:D:D

Re: My new project (yet to be named)

Awesome looking build, coming along very nicely indeed. I do have a minor concern re: the impedance plot, namely the impedance phase angle around 1.5kHz looks to be around -75 degrees. My rough-and-ready calculation suggests that's equivalent to a 2 ohm load at that frequency, which sounds a little alarming. However, it's over a fairly narrow frequency range, and reasonably high up, so maybe not that much of an issue. Perhaps our crossover design gurus can comment on whether this is really a problem or not.

Cheers,

Karl.

Re: My new project (yet to be named)

Made a little more progress on the RUshers. The enclosures are not finished. Just sanded (220 grit) and 2 coats of poly varnish to seal the end grain. They are sitting way too high on top of my Tritrix's, but I will build some temp. stands for them when I get the test crossovers done. Then on to critical listening and crossover tweeks.





Rear shot of the ports and bi-amp terminal cups. These will make it easy to wire the external test crossovers, vs. having to run the wires through the ports.

Re: My new project (yet to be named)

Looking good! You considering Bi-Amping them?

Hehe, ya I'll second the harbor freight clamps...great for the price, but be gentle. I use the orange handled ones when I just need something held reasonably tight, I use my all metal clamps when I really really have to clamp hard.

Re: My new project (yet to be named)

No plans to bi-amp. They will most likely be powered with my old Yamaha 100 wpc receiver. It's built like a brick

Re: My new project (yet to be named)

A question:

What do you do after the poly varnish? Do you just veneer and/or paint right over it? No issues with adhesion?
