hi dennis,

i guess it just shows what an incredible value the phil 3's were, when a kit will cost more than the original completed speakers. my thoughts were that it would be relatively easy to at least put the kits out there, since all the design work has already been completed. even if $4k for a kit, i think these are great speakers, and should still be available, one way or another. of course, less expensive is always better!

best,

I would add my gratitude to this, too! (Sorry, Dennis... Just can't stop appreciating!)

OK--I finally got (almost) enough information to model this, and although I'm not sure about the value of the tweeter parallel coil, as long as it's not higher than about .5 mH, you should be able to get acceptable results by removing and throwing away the old tweet, splicing in a 2 ohm resistor and a 3.9 uF cap to the wire leading to the positive terminal of the tweeter, and then attaching the end of that wire and the negative wire to the appropriate terminals of the new Vifa tweeter. The order of the resistor and cap doesn't matter, just so they're connected n line with each other. The highs won't be perfectly flat--they'll trend down about 4 dB before rising again, but the response should be good enough for the superior Vifa tweeter to improve the clarity of vocals. If you hate it, it's easy enough to undo unless you really did throw away the old tweeter.

Thanks Dennis!

I got email notifications with both replies, so I'll give this a shot and see how it goes. I think I have about $65 in this speaker, so if I can get a reasonable improvement for $20 and 30 minutes of work, I'll take that over spending a lot more for something else.

With Neil Peart passing away this week, and my wife and daughter out, I decided to crank YYZ from Exit Stage Left on my BMR's.


Holy mother of god. Definitely a worthy tribute to one of rock's all time great drummers. Thank you again for these amazing speakers Dennis. I first listened to Rush over 30 years ago, but other than seeing them in concert back in the 90's, I've never heard them like this.

Success!

I swapped out the tweeter and added the cap and resistor in series on the + lead. Also pulled out the factory batting and installed some 1/2" acoustic foam while I had the speaker apart. Before, the highs sounded passable at lower volumes, but were muddy/hollow at reference. I haven't redone the calibration - I only pushed up the level on the center channel a bit - but already it's a big difference.

Thanks Dennis!

Always happy to hear from happy BMR owners. The owner of the shop that will be making cabinets and flat packs for the BMR kit just wrote saying he'll have pricing and details by the last week of this month. I sure hope it's good news.

The stock center is just another of many examples of what can go wrong with a tweeter wave guide. I tried redoing AJ's crossover using the original tweeter, and it still sounded muddy. I'm glad you were able to replace it fairly easily.

This is the tweeter: https://www.parts-express.com/peerle...eter--264-1040 Don't forget to add the 2 ohm resistor and 3.9 uf capacitor in line with the tweeter positive terminal.

Took a step away from the forums for a while and now jumping back in. Just when I was looking to get the AA center and went to the site I found out about Dennis being ill. Hopefully he's well on his way to a full recovery.

What would be a good recommendation for a center, either DIY or off the shelf, that would be close to what Dennis offered?

I believe Dennis said the DCM speakers measured well enough. Its neutrality would be a good fit with the AA's: https://www.ebay.com/itm/6-5-2-Way-C...H/174020666999

Looking forward to info on the BMR flatpacks! As I've never actually heard them, are there any BMR owners in the Atlanta area who would be willing to let me come over for a listen? Would like to do a sanity check to see if it is worth building them. My main concern is about sufficient bass for a largish room. I've never heard a sub integration I really liked (for music at least), I feel the audio waveform should all come from the same plane.
