To answer your question, you will need a higher crossover with the M105's., even 100 might not be high enough. There are comments by our host about how the 106 can handle much more power. It might not seem like it when looking at the price and comparing specs, but going to the larger Low/mid driver makes a big difference in dynamic range. There are people using a 130 Hz crossover with small stand mounts. I'm at a seemingly crazy 170 Hz with LS50's and L12 subs. Yeah, the L12's aren't supposed to go that high, but I can cheat because of room acoustics.
Thank you for all the info ! Maybe I should look into some floor standers. These Arendal 1723 are very tempting and looks like not overpriced (maybe, depend on the performance).
It means that the larger speakers can take more power. You seem to have concerns about how loud things will play. There are spl calculators you can use.
What is your amp rated/measured for power?
What is the sensitivity of the speakers? How big is the room (and distance to main listening position)?
How loud do you want it to be ( this is where the spl reading comes in)?
If you fill in some of the variables, you can figure out how loud it will play. Especially with powered subs, power demands needn’t be excessive in most living room setups.
I have Purifi amps from Audiophonics and they are rated something about 200W in 8 ohms if I remember correctly but around 130W in 8 ohms of the cleanest power, more than that and the distortions are getting higher and higher.
Sensitivity of my current speakers are 97.2db.
Room is 8m x 5m and around 3,5m to speakers from my listening position (my ears).
Yes. Compare the review of the m105 to the f228be I posted above.

In Amir’s same test the f228be peaks at 90db and slopes down to 85. The m105 peaks at 85db and slopes down to 80. So it tells you the floorstander puts out 5 more db across its response range given the same test signals.
and you should still keep and use your subwoofers with them whatever you get.
Thanks man, I will look into these reviews carefully.
I can understand this. IMV it's difficult to find speakers which can play as loud as your current ones (97 dB is a lot) and be better in sound quality. My best guess would be a large passive JBL studio monitor like the
JBL 4367 (94 dB).
Thank you for the suggestion !
It is not easy to keep constant directivity down below a few hundred hertz in a closed box. The Dutch and Dutch 8c and a few others pull off that trick, but mostly box speakers transition to omnidirectional below the baffle step frequency. Dipoles, on the other hand, can have narrower dispersion in the low hundreds of hertz (or lower) to have controlled nearly constant directivity across a wide range.
Another thing that open baffle speakers are able to do is sidestep them problem of cavity resonances, port resonances, and port noise. Obviously it puts a much greater demand on the drivers to produce satisfactory bass in this manner. Although the LX521 can play to well below 30hz they would be helped in maximum output by highpassing them and adding subs.
The last thing that comes to mind right now is the open baffle dipole’s ability to aim the dipole null at first reflection points. If they are positioned and aimed correctly this can reduce the magnitude of the first reflections fairly significantly. I’ve experimented with it and measured the results using the ETC graph in REW- it really does work, and it primarily influences imaging.
Thank you for all the info, it is good to know all of these. My main idea was to keep my open baffle speakers anyway so most probably this will be the time where I will be have two options and will compare them by listening and measure with umik microphone to see what is better for me in the end.
Thank you !
