Winter Projects

[Bob in St. Louis]

I've got a couple things rolling around in my head.

First and foremost, I need to finish the speaker build I started with my nine year old daughter. That's the best one yet.

Second, I've got money in hand for some new drivers ($29) that Danny at GR is going to start selling in January. I'll drive them with one of those 3116 amps that Shadow is talking about. I've been eyeing those for about a year now. They're just too cheap for a DIY guy not to try.

To go with my new PC speakers and amp, I'll have to find some kind of DIY DAC to assemble.

I still need to finish my workshop.

Once the workshop is finished, I'll be whoring myself out to the lowest bidder to build something much more substantial than the above listed cheapo stuff. Don't really care what it is, as long as it requires sawdust to fly.

I also need to put an intake manifold gasket on my truck.
Every winter when it turns cold, the check engine light comes on for several weeks until it can adapt.
Until then, my fuel economy goes in the toilet.   

Many more changes in mind, but those are the only ones that remotely have a chance of coming to fruition.

I'm going to build separate enclosures for the woofer and tweeter drivers of the 4pi speakers. I want to experiment with an Omega 4.5" single driver speaker as the tweeter as well, it's performance as a tweeter surpasses all but the most expensive tweeters and I can cross it over wherever I want, which means what works best to blend it with the JBL woofer. Any suggestions are welcome, but the iteration with the B&C horn will be built pretty much as suggested by Wayne on the pispeaker website:

I ordered up some Sonicaps to replace the remaining old Spragues in my speaker crossover.

So they arrived yesterday and I installed them. Now what? Too much winter to go and my project is completed (except for the burn in). I guess I'll just have to sit back and enjoy!

   Ya think so eh ? Solens ? You can do better. The Audience Aura T teflon are quite the accurate and transparent cap. Just saying

not Solens. yuck. Sonicap and Auricaps. I need a total of 100 uF of capacitance so I cant go expensive or.it would add up to $1000.
