Having been pleased with the passive version of these speakers, I ordered 2x 104As to compare. I'm a little dissappointed at the comparison;
It seems that the volume control is acting as an attenuator before the amplifier rather than altering the gain. Therefore the speakers are very noisy! I have used the passive 104s as near field monitors before but struggle with these thanks to the loud hiss.
They evidently suffer from a low quality, internal amplifier as their tonal quality is inferior to that of the passive version (paired with t.amp TSA 4-300).
Cosmetically, the volume pot protrudes further than the rest of the cabinet which suggests vulnerability to damage and could foul otherwise tight fitting cases.

In an environment that would mask the noise and with appropriate EQ I'm sure that these would find their place. A relatively discreet, active loudspeaker with a "can't go wrong" setup. For the price, I can't complain too much but would still prefer their passive counterparts for many applications.


Top speaker

My work is providing sound for webcasting and with a zoom/ teams call you need a small speaker for the foldback so the host can hear the conversation.
What a surprise, the sound is not what you expect from a speaker this size. Oke it starts at 100 hz, so what! It can go very loud.
You can also use it for small p.a.. Fill in speaker, on front of the stage or mount it on a stand.
I like the size and the various ways you can mount the speaker.
Build to last, old fashion wood, no plastic.
Conclusion: value for money!
Other more expensive active speakers are less versatile In mounting and size.
A have now 4 104A speakers and I am sure that more will follow :-)

Used for extra fills for large rooms, outdoor fills for summer events with some people leaving the room, small PA for background music and home/personal use. Amazing sound quality, lacks low frequencies which is to be expected but does a pretty good job considering. The volume these can reach while maintaining the quality is amazing given the size and cost of the speakers. Brilliant speakers. Used as rear/side fills for discos with the main subs taking the lows. Used without a sub too and some bass there although not much and volume can't be pushed as high. Will be buying more over time and will end up with them all round the house and being used for most events. The standby feature is very useful too. The ones at home just go to sleep and wake back up when I play something through them. Included brackets are great too, allows me to hang from lighting bar at the rear of a room and even from the ceiling at home. Highly recommend.


Great sounding and useful little monitor

These monitors are a really useful box to have in the arsenal. Somebody needs a monitor in a room - perfect. Hot spot monitor - no problem. I use mine a lot for testing in my workshop too. Very useful and can get a surprisingly good level out of it too.
