Schwinn, while you still have the Avatar crossover out, would you mind measuring the dimensions of the cutout in the cabinet and posting it here?
Enlarging the cutout to fit an Eminence crossover wouldn't be a problem, but if the cutout is too large in either direction, then this idea would not work. Let's see if this really is an option.
I think the Eminence would hold up better, and the crossover design is a real two-way instead of routing full-range to the 12's and highs to the Peerless. Plus you get lamp protection and current limiting at high volume for the Peerless.
I would send the cutout question to Dave Noss, but he's going on vacation this week!
Well, my humble opinion of course, but I tend to not put any frequencies through a tweeter that don't absolutely have to go there. I put as much frequency range as possible through regular cones, because they tend to sound the most natural. If a speaker's got good response up to 3K, I'm not inclined to cross it over at 1.6K, sending those frequencies instead to a tweeter. Even the best tweeters get kind of "honky" sounding in the lower part of their range, so it's usually best to let your woofer or mid handle as much high end as possible.
And in this particular situation, these two components complement each other really well. The 12's go high enough, and the tweeter goes low enough, so that a simple, cheap 1st order high pass filter is all it needs. You could certainly wire in a bulb for protection if you want, but since the tweeter handles 100 watts, I really don't think it's necessary. If it were a PA cab, maybe. But the most high end you're going to get out of a bass is going to be transients while slapping, not sustained wattage like you get from vocals or synth.
I dunno, I guess it's also 'cause I'm a cheap b*stard. Nothing wrong with Eminence crossovers, they are nice, but kinda overkill for this situation. Kinda hard to justify putting a $100 crossover into a $325 cab. Parts Express has their house brand (Dayton) for about half the price, so if I were to consider doing this, that'd be my choice. All the specs on them look good. Since the high pass is a 3rd order design, the crossover point is OK for this tweeter as far as protection from excessive low frequencies. 1.6K would be too low if it were a 1st order, marginal if it were a 2nd order. Also note that the Eminence crossovers only handle 400 watts, the Daytons 600.......that's due to the limitations of the coils used in low pass filters. You can build a low pass circuit that'll handle 1000 watts, but it ain't cheap. If you put either of these crossovers in an Avatar cab, you will be lowering your wattage capacity a good bit. If you let the woofers roll off high frequency response naturally, you don't place the additional limit on your wattage, and you save a few bucks, too.
Now, it could very well be that a different crossover scheme might sound better; if I had the time and resources, I'd play around with various crossover points and see what sounded best for each and every cabinet. But, time and resources being limited, the first thing I try is what looks good on paper. If it sounds really good, I don't put a lot of time and energy going for "great". You end up wasting way too much looking for that holy grail.
Again, all just my opinion, your mileage may vary......
