I suppose, when I went through my router was fine, I didn't go real fast, but it didn't really slow down or bog down at all, and it is a cheap router.

It is hard on them, we've burnt out the brushes on them in 2 or 3 days of hard use on commercial jobs. They would actually come apart. It does damage to the bearings as well. Then there is play in the bearings, that increases run out which makes the bit chatter which makes more heat.....it's a vicious cycle.

That's cool. I'm kind of a weekend warrior when it comes to building stuff. My router gets used about 3 times a year, I'm not not concerned about a little wear on it. If I had a good router or used it a lot I would be though.

This is simplified to save time.............
1. You'll get far better results taking router cuts a 1/3 at a time. Your tooling (bits) and your router will last much longer.

2. More importantly-deep one pass routing yields far poorer cuts than multiple passes.

3. Much more importantly-multipass routing is safer than single pass.

I need more clamps

Do you guys find it necessary to silicone the seams?

BIG thanks to Danny for sending those Sonicaps right out - got them today.

Joe, if your saw cuts are accurate and square, the resulting tight-fitting joints will be maximum strength and of course won't contain any gaps, so caulking seams is unnecessary.

Good, that was my feeling, too. Thanks.

Work continues. Got the first xover network soldered up. What do you guys do to connect the wires to the speakers and speaker cup? Do you solder them in place? I notice there were no connectors in the kit. I want to wire it up temporarily to test it.

Thanks!

Oh, and if you don't have one of these hinge center markers, you need one. It's one of those goofy things I thought I'd never use, but it's awesome for marking the center of the holes for the speaker screws.

Yes, solder them directly to the speaker terminals and put some heat shrink over the joint if you can.

We have sound! Hooked it up and everything sounded perfect. The side panel was a good tight friction fit and is in the clamps now!

I'm so excited

D'oh! I just realized I forgot to put the foam on the inside of the last panel

Ah, well, shouldn't make much of a difference. I did remember to put the fiberglass insulation in before buttoning it up, at least.

You can still put that in through the woofer holes.................

Thanks, don't know why that didn't seem like a good idea. Worked fine.

One's done, the other's in the clamps. I still need more clamps

Now I've just got to decide on a veneer. (I figured out how to do the thumbnails, so click if you want to see full-size)

Here's a question: One of the tweeters has red paint on both terminals. I can make a fair guess which is which, but is there a polarity mark somewhere else? I didn't look too hard, but I didn't find anything last night.

Thanks,

-Joe

Now there's one I haven't seen.

I'd take a guess. You'll know right away if it is not right. If not right the 2kHz region will have a big sucked out area in the response. If right it will be smooth like the other one.

Sorry about that.

Sorry about that.

No worries. One looks like it may have been splashed on. I'm assuming that's the negaitive. We'll see when I plug 'em in. This weekend should be the first listen in the house. Going to run them naked for a bit until the wife decides on a veneer

Ain't this fun! I built the Av-2's several years ago now and I still have them in my HT. I've enjoyed reading this thread because it brings back some fond memories of some of the challenges I went through on my first kit. Originally I made them when they were called the AV-1+. So you have upgraded parts and insulation not available at the time. But let me tell you that is one sweet sounding speak. You'll love acoustic guitars on it.

I also bought them with the baffles as part of the kit but I later did a center channel and rears where I did the entire enclosure baffle included. I ran into the same problem on the first set with the tweeter magnet not centered as well. Raw gave you the correct answer. That's what I did.

Looks like you're doing a great job. Thanks for the pics. Make sure you post a pic of the final product when you're done. I'd love to see them.

Is one terminal wider than the other one? I was thinking it was, but maybe that is on the woofer...?

The + is on the woofer. The tweeter ones are identical.

I'm fairly sure which is which, and if not I'm sure I'll hear it, like Danny says.

Thanks,

Could you guys make some comments regarding using fiberglass insulation with ported speakers? How much of a concern is it, actually? Thanks.

Nostalgia · « **Reply #38 on:** 15 Dec 2006, 10:17 pm »

Yay! Almost ready for testing...

First listen, left channel is muffled. What? Took it out to the garage, removed the drivers, double-checked the crossovers. Everything's fine. Huh? Put it back together, bring it in, hook it up, and it's perfect. Huh?

I've been playing them for the last 1/2 hour, and they sound so much better than my old speakers it's ridiculous! I played a few reference CDs, and the imaging and detail blew me away. I'm very excited to hear them as they break in.

Thanks!
