I've used both pro and home drivers in the same and separate setups
with some very expensive scan speak and eton drivers amongst them

I now only use pro drivers
and the assumption that they don't do well at low volumes is rubbish you just have to choose the right drivers same as any build .they are not all large xmax/motor designs

look to altec ,phl, ae etc.

I always enjoyed utterly baffling individuals who take a listen to a pair of high efficiency loudspeakers I've built.....the pair all alone in the middle of the room. I'd hear the "What's hooked up to it?" yelling over the music....I'd pick up the FM "Walkman" half the size of a pack of cigarettes running some milliwatts into the enclosures. I'd get the weirdest looks!

Basically there are a lot of disadvantages to low effeciency speakers. I've heard some that sounded fine, but I have never associated the sound quality with low effeciency. High Efficiecy speakers have a lot of advantages and the only downside being that poor quality electronics are shown for what they are. So if you're using Lousy (but powerful) amplifiers, etc., be sure to use Low Efficiency speakers...Your ears will thank you!

I'm using 2 Crate 2 x 15 guitar bass cabs as my speaker system. The bass cabs have 2 15" Eminence Delta each cabinet. I added an Eminence horn twitter for high frequency. The twitters are connected through Eminence 3-way cross over, but the woofers are not. They are running without passive cross overs.
But, I'm using a Bose 901 Series IV active cross over between the pre-amp and power amp. Sounds freakin great. Not harsh for for home use and can be played at low volume levels and still have good bass and treble. The mid bass and mid frequencies are excellent. The sound doesn't sound thin at all like the Infinity SM-150 and other DJ speaker systems.
Yes, I have Bose 901 speakers. And as far as the active equalizer, they are set a bit below their mid settings. My pre-amp bass and treble control settings are also set below mids. I'm using Yamaha C80 and m80.

I'm not sure I should give relationship advice, but you need a new GF.
This is just the tip of the iceberg. She's not even your wife and she's telling you what speaker to build. Not a good sign. She's going to have a problem with everything. And if you marry her it will be worse.
I give up lol

She just looks at it from a girls point of view.
You can be glad she listens to your plans at all..

Btw., subs don't have to be huge, today good speakers and poweramps come cheap, so you can build small and tune low and then boost at Fb.
sounds good and is much less to carry.
