Geez.

I hope you're getting something for this. (Apart from aggravation, I mean)

Nope. I offered to do this at no labor charge, just for the opportunity to be the "trailblazer".
I guess I got what I asked for.

p.s. Although, if the project fails entirely, I'll have one helluva real nice end table for my troubles.

Would attempting the prototype described on this page help any ? http://www.diyaudio.com/forums/multi-way/195734-nelson-pass-slot-loaded-open-baffle-project-28.html

So Bob - what happened??

Bob in St. Louis · « **Reply #88 on:** 19 Sep 2011, 01:02 pm »

I have read the original article on ETM with great interest.

I found out yesterday morning that the problem with this project wasn't the alignment, nor was it the drivers.
Seems it's my amp. Sometimes it works, sometimes it doesn't.

Yesterday I caught it in the act "as it happened".

I've already sent my apologies to Darrel Hawthorne for "making" him buy those two Eminence KILO drivers.

He's a very forgiving man.

more later.....(when I recover from the humility)

Oh. Well that sucks but on the bright side you don't have to rework the baffles..... or did you already do that.....

Bob in St. Louis · « **Reply #90 on:** 19 Sep 2011, 03:36 pm »

John, I had taken the layers of the RiPole apart (a simple process) and set the two layers that contained the drivers upright, much like you'd have a OB bass driver sitting in your room.
This morning I reassembled the RiPole back to it's "normal" state. Fortunatley, I had not cut the piece up, or modified it in any way.

I got to hear the ripole today - i want one!

It would be an amazing foundation to a full ob system, to provide the bottom octaves. Didn't sound boxy to me. Even though it wasn't optimized today, i have high hopes for the design & hope the owner has fun with this monster.

Bob's cave is so cool, with a click of his mouse we can hear the IB system alone, IB + a pair of auggies on his duet baffles, or the auggies + ripole, or probably any combo therein.

Bob will have to be the judge, but to me, the ripole's had proper tone & were accurate to low, low depths. In comparison, bob's IB system has more output for sure but isn't as musical.

thanks again for a good day today bob!!

2.5 kilowatts

Yea, we had a change of plans regarding the boy getting the amp. The storm we had the other day took out his receiver. I was going to give him the one I use in the workshop, but that one is smoked as well. Don't have much need for an amp to power his subs without a receiver. So basically he's got nothing right now. That's why the Crown is running the RiPole.

In all, I've got five bad amps right now.

JohnR · « **Reply #97 on:** 20 Sep 2011, 12:33 pm »

Bad amps need to be put into the naughty corner.

But seriously... any chance of some measurements? I'm DYING to know...

Bob in St. Louis · « **Reply #98 on:** 20 Sep 2011, 12:59 pm »

That's a pretty nice "naughty corner".

I'll do some measurements pretty soon. What kind would you like? Any requests?

Bob

......EDIT: Nothing fancy, all I have is a Rat Shack Digital meter.
I can't do the fancy graph stuff.
