CBM-170SE's + Rythmik L12 = Oooh-la-la

Mazeppa, yes, I am using the bass management of my Emotiva Fusion 8100 and set both the sub and the 340s at 80Hz.

The 340s are in a shelf (not just "on" a shelf), so to avoid undesirable interaction of the rear port with the enclosed space of the shelf I am not using them full range. Crossing them at 80Hz is well above the tuning frequency of the port and therefore it makes them behave virtually as a sealed speaker.

Plus, it gives significant relief to my AVR, as reproducing bass is notoriously taxing for amps. The Fusion 8100 has very robust output stages and solid power for being an AVR, but still it is not as capable as a system with separate (110Wx2, 80Wx5 or 65Wx7, all channels driven).

The high sensitivity of the CMT-340SE and the added power and dynamic provided by the L12 makes for a very well rounded combo. It sounds way better and powerful than the little money I spent would make you think.

I have almost all of the bits and parts to put together an analog, 24db L/R crossover and I'm still considering giving it a go @ 80Hz.

My amp is 2x125W into 8ohms so I am listening for any undesirable overlap between between the L12 and the 340's. So far, it seems good at the 2 clicks below 80 on the L12 and I remain undecided on adding the crossover. I'll probably wind up trying it eventually just to see (hear) if it helps.

Agreed that the 340/L12 combo is very effective at a reasonable cost. No buyer's regret at all for me.
Good dynamics, well balanced & nuanced sound from low to high such as they produce are to be envied at any price point.

I had an Emotiva 2 channel amp (excellent build quality and performance) for a while that I was very happy it with until I tried the MOSFET sound and fell for it big time.

My system is also very tolerant of recordings that are less than optimal, as much music from the late 60's, early 70's (my main jams) are.
However, I tried some MP3 material for the 1rst time yesterday through the 340/L12 combo and, well, let's just say that the MP3 format remains relegated to a low volume, background role for me and will not do if I want to listen to the music.

Interesting that your 340's do well IN a shelf. Less than ideal placement, but they shine for you anyway.
Speakers that sound this good and are so versatile in placement and usage have got to be a rarity.
The reviews & testimonials of MOST speakers contain a caveat (or caveats) about something, but it seems almost all 340 users say hook 'em up where you can put them with the electronics you've got, play what you like and you will be pleased with the sound.

Count me in that number.
