Um, "easy" is not the word that comes to mind...

The main hang up I think most everyone has is Firewire to the sub amp and having to have some sort of powered DAC at each sub. I have three subs, two in each front corner and one in the rear of the room.

I don't really have that big of a problem with Firewire from the computer to the unit itself, although I'll have to buy some sort of Firewire adapter for my laptop.

The interface appears simplistic enough. The unit itself needs to have simple and current connectivity, not something we have to jump through 10 hoops to make work.

I like much about your approach of digital to the speaker as well as the ability to drive each speaker/driver locally.
While this may be a bit out of the topic - are you considering a unit that would do full range DRC and Speaker/driver correction?
Basically I am thinking of a systems that would use digital in and drive potentially each driver with a seperate amp and would function as the crossover in the digital realm doing phase/amplitude correction. This would be similar to Audyssey system but operate in digital to the speaker/driver.

I keep wondering why anyone would want to reinvent the wheel and give it a fragile Firewire axle?

brucek said it all. The AV/HT world is now aching for a BFD without the trimmings and tidied up in detail. This is a real worldwide AV/HT need that nobody is listening to. Nobody!

Rightly or wrongly we sell the idea of electronic subwoofer equalisation to everybody who will listen on the AV forums worldwide.

We simply want a BFD that can filter right down to 10Hz, has silent on off, doesn't hum and doesn't look like a cheap 70s scifi spaceship prop.

Behringer's shortsightedness in removing the 1124P from the market without offering a real replacement is so stupid they should crash and burn!

They were given a heads up by Sonnie but chose to ignore it because it probably wasn't in their "normal" pro-gear marketplace. They obviously haven't a clue about their customer base! Or couldn't care less about the hundreds of thousands of potential customers now looking at SMS1 and turning their noses up at the dumb price tag.

Thousands and thousands of 1124Ps were purchased by sub owners worldwide from any music store that had them. Sub owners loved them or hated them but they still learned to use them to make their subs listenable in perfectly ordinary domestic rooms. John M is a saint for producing REW! brucek and Sonnie should be honourably knighted for their work in making REW work for idiots like me.

Most sub owners don't want a computer in their AV room/HT except to set the sub up with REW + BFD and then forget it.

Most sub owners don't want to spend more than a couple of hundred dollars making their sub's work as nature intended. That probably includes the SPL meter too!

They want to use cables they recognise as cables. Balanced XLR and USB.

Offer us a tidied up BFD1124P and you will have to fight us off. Provided you make a 230 Volt 50Hz version for Europe etc.

I wouldn't buy your Firewire box with all the dangly bits if it cost pocket change and fitted in a matchbox. It doesn't interest me. It has no relevance in my AV world. A BFDi (improved) does interest me and I would pay twice what my trusty 1124P cost me without batting an eyelid.

I'd love to see someone develop this to handle up to 5-6 subs and independently measure and control them.

I will end up at some point with a projection system and CIH and have room to do

3 x Definitive BP7006 for the front L/C/R and each tower has a 300w RMS 8in sub, plus room for two more LFE subs

EDIT:I hope and plan on doing Denon AVR3808 + Emotiva BPA-1 (3 for the 7006s) and would love to set the towers to small and use the "X" device to be a go between for LFE to the amps then to the towers LFE RCA input. Along with this two subs in rear or two small IB...

It sounds like you're talking about custom full range speakers. I think I can see how this sort of device would add value.

Would that market require DACs or would they want to receive a standard IIS digital stream and build their own DACs?

Is $150-$250 per 3 way speaker too much for a digital filtering and distribution system for the DIY speaker market?

Seems a bit pricey for a mono unit. Not to mention, not sure how many DIYers will find the extra AD/DA processing attractive (sure wish some manufacturer would make a receiver or pre-pro with volume-controlled digital outputs). And once again, you’re competing with Behringer’s cheap stereo crossovers... They’re pretty popular on the home front.

I like Barry's ideas .
I like Digital to the sub, specially over a 20ft run.
I myself will be willing to pay $250, I am about to pay $250 for a Behringer FBQ2496 and it is not even supported in Canada anymore.
BTW will this be available here in Canada at this cost? are you all talking USD or CDN $$$.

[rcarlton]

Anything new on the idea front bvwj?

[muzz]

My belief is that MOST HT folks like/Prefer HDMI for 1 reason, and really only one reason..
Ease of use/hookup because of less cabling
Other than that, I don't see the benefit myself.

I was reading this thread, and was going to make a comment....but this quote above did it way better then I could have. The BFD is a good product....remove all the button and lights, give it a USB port that I can use to dump filters that I create in REW, and a few memory banks for storage, and NO external adjustment ( so once it is set people don't fool with it ). If you are using a BFD....you are already using REW...so why does the unit have to have a mic and preamp built in. In my opion..less is more.
