Hi,
I really like the sound of full-range speakers and I'm going to build a pair for a friend. His living room is quite large so some bass augmentation is necessary. I've been trying to figure out how to build a FAST speaker using W8-1772 and MCM 55-2421 woofers. I plan to use 2 of these 4 ohm sub drivers in series. My dilemma is should I bi-amp the full range and sub drivers with an active crossover? If I do that the system becomes more complicated, needing two amplifiers, more cabling, etc. I also considered using separate plate amps to simplify things but the plate amps I find are either too powerful (ie PA) or don't have enough power. I'm building the speaker for a friend who isn't technically savvy and likes things really simple. So I want to let him stream from his phone via bluetooth or wifi and avoid burdening him with extra knobs and buttons to fiddle with. The last option in my mind was a passive low crossover and a 2 ch integrated amp to drive both speakers. But passive xo's are totally uncharted territory for me. Any suggestions?
Best,
Selim

Get a 2.1 amp board w/bluetooth. This will have an internal low-pass for the sub(s).
Two little boxes for the TBs, two medium to large for the subs.
Put the amp in one of the subs.
A cable to each TB, and one to the second sub(they will be in series.
A simple, two component high-pass for each TB, can be in the sub box.
You can do some EQ in the phone or other device that sends the bluetooth signal.
Power and primary controls at the amp, secondary volume on device.
The amp can cost less than a passive low-pass by itself, high-passes are relatively cheap.

Thank you for the recommendations. It looks like a good solution in terms of practicality. I've looked at the Dayton Audio 2.1 plate amp. It has bluetooth but it has only a line level sub out. Then there's the Lepai:
Lepai LP210PA 2x30W + 60W 2.1 Channel Mini Plate Amplifier TPA3118
This amp is rated at half the power rating of both the full-range speakers and half of one of the subs. So when there are two subs connected each sub can get a maximum of 30W. So it looks like the 2.1 amp is quite a bit under-powered and it has no bluetooth. 🙁
Do you know of any other brands, models that would be more powerful and has bluetooth?
