And then they were gone.
Philharmonic have removed this generation of the Affordable Accuracy Monitors from the website.
I just discovered this thread. I'm happy to hear that buyers of the kit have been satisfied with the results. As has been noted, the Dayton tweeter requires some help. That's why I switched to the Morel for the second iteration of the BR-1 mod. Unfortunately, Morel slapped me with a $40 increase per driver, and there went the Affordable part of the kit name. I ended up having to voice the Dayton tweeter down about 2 dB and cooking up an unorthodox crossover topology to flatten in out, but in the end I actually prefer the sound of the latest kit to the Morel.
Parts Express offers great prices and free shipping on orders of over $100, which allows me to get the cabinets and woofers to customers free. That's one of the reasons for the kit approach. The other is that PE refuses to provide the cabinets with sufficient packing protection to handle the weight of a pair of assembled speakers, or even to protect the grills on empty cabinets from damage to the grill guides. If I were to assemble the speakers here in my "factory" (which also functions as a kitchen), I would have to cut multiple blocks of 2" styro blocks and cram them around the speakers. I did that for the first AA back in the day, and I'm still cleaning up electrically charged styro particles.
I sold out of the factory-assembled Xover bords much faster than I expected and I haven't decided whether I'm going to order another batch (the minimum order is very large and expensive). That's why I took the kit down from my web page. I've had a pair of AA's out for a third-party review for several months, but the reviewer came down with a bad case of Covid Delta and is just now finishing up the review. That review might help me decide whether or not to continue. I don't make anything on these, but "loss leaders" are sometimes good business practice, and I really would like to offer a neutral, wide range speaker for people on a budget.
In complete candor, I have had the AA Klippel tested. It did very well in the areas I think are important (on-axis and listening window), and not so well in the area I think is much less important (far off-axis response). The Dayton woofer sinks like a rock after 1900 Hz and also requires a trap circuit to tame a sharp break-up mode (which the PE BR-1 doesn't include), and as a result there is a directivity mismatch at the crossover frequency. There's nothing I can do about that. There's no way to get more overlap between the woofer and tweeter without unleashing the breakup mode, and I can't fashion a tweeter wave guide even if I thought it was a good idea. The issue doesn't bother me when I compare the AA with 2-ways that perform better in this respect. But maybe that's one reason to buy a pair of BMR's instead.
