Howdy... If you didn't happen to read my little story in the intros section, I'll give ya the down low on me. I'm a car audio guy... so a lot of this home stuff is new, and kinda scary (to me at least)!
Now I've built a lot of enclosures, sealed, vented and beyond. (okay... so a dual-reflex bandpass is as far as beyond went, but who's counting?) But my real problem is I've got no crossover experience other than "Yep, you put these wires into this magical box here, and that one goes to the woofer and this one to the tweeter" and a couple of active XO's.
So, now on to my question... (sorry for the huge buildup for such a silly question) Is the Dayton BR-1 a good beginner project? I'm just looking for some clean sound, and to get my feet wet. (I'm quite sure this won't be my last pair of home speakers) And out of curiosity, would the 295-306 be an acceptable replacement for the included 295-306? (PartsExpress numbers.) I only ask because I'd like to use them as computer speakers to replace my currently unshielded Realistic Minimus 7's
Thanks in advance for the opinions and advice.

The BR-1s are a great beginner project IMO.
I'm not golden-eared enough to give an objective description of their sound, but I am very pleased with the pair I built a month or two ago. The depth of bass they put out is quite surprising for such a small box, and the highs are very crisp. Above all, they're great value. Some have said the midrange is a little recessed, though.
The shielded woofers have been used as drop-in replacements in other projects with success, so I would think they could be used here without problems. You might want to consider shielding the tweeter too -- PE sells 69cent bucking magnets that provide some shielding effect when glued in reverse polarity to the back of the tweeter.
This page suggests some tweaks. I considered bracing my cabinets, but they seemed solid enough out of the box to me, so I didn't bother.

Thanks for the link, that'll be quite helpful, but can you explain a little more about the magnet for shielding? You say I've just got to glue it in reverse polarity to the tweeter mag? And that won't mess anything up? 😕 It doesn't seem overly difficult... and maybe that's what gets me. Accursed simple things!😉
Thanks again... I think I'll get on the horn and order a set or BR-1's tomorrow.

It's a ring-shaped magnet that you glue to the outside of the back of the driver, so that it's repelling the main magnet. This (hopefully) has the effect of cancelling (or greatly reducing) the outside field.
Two-part epoxy cement works well (it needs to make a pretty strong bond) and you'll need to find something to clamp or weigh it down with while it dries.
It will change some of the driver's parameters slightly, but shouldn't be enough to make any great difference. The Loudspeaker Design Cookbook has more details, but I don't have my copy handy at the moment.
