Hey Kevin,

Sorry to revive a dead horse here (well this thread has been dead for a few years but hopefully the speakers are alive and kickin.) I was going to pm you a few questions but I figured people would maybe find this info useful, but I have a few questions for ya about these amazing speakers you made.

First question is what was the purpose you made these for? Stereo music, movie theater etc, and are you currently still running them?

If you haven't heard back from Kevin I can help with some answers.

4/1- April Fools. They're gorgeous, wonderful work.

I feel like the fool for not getting that now. Was thinking 4/1 ratio and was totally confused. Thank you for the kind words.

The 4/1 question is going right over my head?? But I believe you are saying you like em, thanks.

I used the pink foam board to ship the Silverbacks to Kerry. Lined the box with a 1" thick wall of it all the way around. It worked well and they arrived with no damage which is saying something when you consider how rough UPS or FedEx can be on boxes, especially heavy ones.

And they definintely are super heavy. I think almost 40 pounds each IIRC.

Jim G always used to sleeve the cabs with pink foam-board.

KK: Re: protecting the babies during a move.
I like the idea of using bubble wrap or carpet padding, as you already discussed.

My "bright" idea is to then cover the sides with cheap 1/4 inch paneling.
I don't think you would need a complete box, just covering the sides should do the job.
I think that would really protect them, and be fairly cheap and easy.

Wow! That's a nice looking graph. Hope you get to feeling better by the way.

4thtry Thanks Bill, I appreciate you providing pics and info on the "DollyHoppers". I'm sure there will be a few ideas borrowed if you don't mind.

Started feeling a little better late this afternoon and decided to play around with the DSP some more. Just have to say it, might be growled off the forum for it, but I think all newcomers, newbies, what ever you want to call us could learn a great deal faster if they picked up a DSP and Mic to play around with first. Not only seeing but hearing your adjustments "Real Time" is amazing and educational at the same time. To be able to flatten a peak or raise a valley and hear the difference after the adjustment is just too cool. I cant think of a way to train an ear any faster than this. If any of you are on the fence about trying the DSP, once you take the leap, you'll be kicking yourself for not doing it sooner. Tons of fun would be an understatement.

bcodemz (Brian) spent a little bit of time on the phone with me Friday afternoon and walked me through a quick session on the DSP. I made a few more adjustments this evening and here is the result: I haven't spoke with Rick about how to adjust or how much to adjust the bass region on the arrays yet. I have some issues with room boundaries also.

I haven't seen what Bill did but I did see his "Line hoppers" at the show. Any pics of the cradles he built anywhere?



I can and I may build some kind of case or cradle after seeing your comments and John's, you guys are making me nervous about transporting these things now.

Kevin,

Here are a few pics and dimensional data for my custom cradle. Please note that I only built one of these and it was only used to transport the linehoppers, one at a time, from my car to the resting place inside the venue.

Your speakers have a continuous slope and curve, so a cradle may not work. Your speakers might slip loose from the dolly when you attempt to push it forward. My Linehoppers have a 13 7/8 x 8 1/8 x 5" upper back side protrusion that is cradled securely between my custom 1x3" cross member supports. This protrusion fits like a glove and keeps the Linehoppers firmly in position as I push the dolly in any direction.

Parts List:

Qty Item

2 42.5" long 2x4's (cut from hand selected 8 foot long 2x4 at lumber yard)
2 15.75" long 1x3's (for cross members)
1 17.5 x 30" dolly with four 3 inch swivel casters (local hardware store)
2 4" swivel casters (to replace the original two 3" swivel casters)
2 4" fixed casters (to replace the other two original 3" swivel casters)


I bolted two 42.5" long 2x4's to the dolly with eight carrage bolts/nuts/washers. I also bolted and screwed two 1x3 cross members to form a cradle for the upper Linehopper protrusions. To protect the finish, I stapled some old discarded carpet remnants to the 2x4's and 1x3's. And I replaced all 4 casters so I could increase ground clearance and have the ability to push the dolly in a straight line, just like a grocery store cart.

Hope this information is useful, should you attempt to develop something along these lines.
Whatever you do, good luck and get well!

I like using fleece blankets for transport as the drawer liner will stick and peel onto the cabs in the heat. Been there done that.

Something to think about...

Thanks for the insight on transporting them Tom, I'll keep that in mind. And I guess I should thank you for the reminder of how far away MWAF is! Man I've got a lot to get done in between now and then.

I wish. Spent a little time Friday afternoon programming a preliminary setting for the MiniDSP and played that for a couple of hours on the one enclosure that's complete. That was fun! The output from just the one enclosure is darn impressive, can't wait to hear both of them playing together. By late Friday night, knew I was sick. The flu has been going around at work. Spent all of Saturday in bed or on the couch. Was feeling a little better last night and thought the worst was behind me but then the fever came back with a vengeance. Seems like most of the people at work had it for at least a few days.

If I can muster up some energy today, will try to finish loading the drivers into the other enclosure. Also need to work with Rick and get his input on the programming.

Yikes! Hope you feel better soon. Get some rest.

Soooo Are they broken-in yet
