Upgrade your PC speaker setup to something more professional and versatile.
So…I have been using monitor speakers for years for my PC sound needs, they are self-powered so do not need an amp and tend to have minimal footprint. I have my PC connected to my lounge TV and my PC use is generally done via the couch with Bluetooth mouse/keyboard. I am not a sound engineer or video editor so am not overly fussed about "flat" sound on my speakers for accurate reproduction. I want my speakers to fill the room with sound, be of good build and provide a good soundscape for music, movies and the occasional gaming session. I have ASD so have been cursed with a keen ear for sound defects, crackles, hums and general distortion. I prefer high quality MP3 (high bitrate FLAC) as opposed to streaming as I can hear the sound difference and find it makes a difference when you crank it up. I have traditionally paired my monitor/active speakers with a sub to give the set up some lovely warmth and thump and have an external soundcard with phono outputs to eliminate any interference from inside the PC case. I use the FX-Sound app in place of any bundled soundcard apps as it enables me to switch EQ for optimal listening experience – anyone who watches movies on PC can tell you how voice can become faint with general settings.What I had previously:I bought my last set of monitor speakers in about 2010 – a second hand set of M-Audio AV30s. They did the job quite nicely but did need the sub as they lacked any thump. I kept this setup over the years as it met my needs perfectly, I used the best cables I could and tweaked everything as well as I was able.However, after 16 years of use and no previous problems, the speakers decided to give up the ghost. Maybe was just age or a connection finally melting (they were on almost every day for hours) but they started to buzz and my admittedly shoddy knowledge of speaker repair failed me.What I wanted:I therefore decided to look for suitable replacements. To find something at least as good or better on my limited budget (under £100). The speakers had to meet my needs (as listed above) and hopefully last another 16 years.As am sure you have seen (you are reading this review after all) the choice of speakers is huge. I briefly considered bluetooth options but as my PC has this and I am a bit of an audiophile I decided it was unnecessary and added an extra potential for wear down the road. I felt comfortable with M-Audio as the previous pair lasted so long. I looked at other, well-known brands and weighed them against these ones in terms of specs, price and personal experience. I looked at some of the more unknown brands, which seemed to offer good value but instinctively I felt might not have the build quality.So why these ones?Ultimately these speakers seemed to off the best deal for me, I liked the fact that they featured built in high/low adjustment and seemed to be well insulated from interference. They had the right wattage to fill my large lounge and enough inputs to be versatile. I liked the look and the fact that they were a brand I trusted. Lastly, the price was right.So, any good?Well off the bat I was pleased by the good packaging, they included all the cables one might need – I did have to buy a longer 1/8 inch audio cable as my speakers need to be 4 meters apart (4M, 3.5mm to 3.5mm Stereo Aux Cord). Luckily the speaker to speaker cable was standard and only cost £3.After setting up and attaching the (included) foam pads to the bottom of the speakers I wired up my system to the PC and sub. I kept the sub off and tested the speakers with movies, streaming and music (*note, turn these speakers on by turning the volume knob). I adjusted the low and high slightly to suit my taste and found that even with the sub off they had a nice warm sound with a nice bit of thump. I am sure this will improve as the speakers wear in a bit (turns out this is a thing). After turning the sub on I was treated to the full potential of my setup and found that with some small adjustments was able to produce a well-rounded, room filling sound with the speakers only quarter full. They are certainly loud enough! The highs and lows seem accurate and with the right EQ settings (thanks FX Sound) I was able to hear good detail on everything I tried.The build quality seems good, and I did not notice any hum or unwanted noises when no audio is being fed to the speakers. I was able to turn them way up without hearing any distortion save the rattling of objects on my table…In conclusion, I would recommend these speakers as good value for money and quite suitable for anyone wanting to upgrade their PC sound from “PC Speakers” to something a little more professional. I would imagine that you would have to spend a lot more money before you had any noticeable difference in sound quality. Only time will tell how long they will last but so far so good.

Read this before you buy
First of all (as pointed out in other reviews) these speakers DO NOT output 120 watts (as stated on the box). On the very last page of the user guide it quite clearly states that these are 2 x 25 watt (RMS) speakers with a total peak of 120 watts. This means that the speakers will take short bursts of up to 120 watts without blowing the cones out! This depends on what is put through them. Also, only 1 speaker is powered (has an amp inside with controls and input sockets), the other is just a speaker in a cab.The sound quality is very good for the size of the actual speakers, although this may change if operated at full volume. I was impressed with the bass response and the built quality is also very good.Inputs include standard 'guitar lead' type sockets (left and right), RCA sockets (left and right), a 3.5mm AUX input socket and a headphone output socket. Also there are low and high frequency EQ cut/boost knobs.A selection of speaker connection leads and a mains lead are included and also some felt pads that can be attached to the bottom of each speaker.Finally, I would like to thank Amazon for prompt delivery. I bought these 'Like New' (at a discount) from the Amazon warehouse and when unboxed I could not tell them apart from a brand new pair.I happy with my purchase although these speakers are not as loud as I expected.

M-Audio BX 4 worth every penny.
For the money these sound great and look the part, resembling their bigger/older sibling the BX 5. Bass response exceeded my expectations, both high and low eq can be adjusted around the back.I've had these for 2 weeks now and can say I am really pleased and would recommend. My only gripe is (and this could be a deal breaker for some) the sound quality from the headphone socket is awful, with a significant amount of bottom end missing when compared to my audio interface headphone out. I also replaced the cheap speaker connecting cable as it is really thin and longer than I need.UPDATE: I tried the headphone socket again and it seems fine now, maybe I hadn't plugged it in all the way before.

Great sound quality, in particular the bass! Very affordable and sleek
Amazing speakers, very good value. Had been looking for affordable speakers with good bass as well as good sound quality in general and these certainly tick all the boxes! Look sleek, can get very loud and the bass is perfect, great for techno which is what I was looking for, doesn't come with a cable to connect to my DJ decks but luckily they're quite cheap on amazon. 10/10 speakers definitely would recommend, especially if you want a speaker with good bass.

Woah!!
I got them because i had a lack of space around my current desktop gaming pc and was previously using a minisystem plus speakers. I though i'd give these a go simply for the fact that they are a lower footprint on my workspace. ..Oh my god..the sounds is SO much better and i hardly need to turn the volume knob up at all!! It starts low at 6 oclock.. I have only turned it to 7 maybe 8 oclock and the sound is what i would normally have on my minisystem but my minisystem would nearly be maxed out!! Lots of headroom if i wanted to annoy the neighbours.Nice and clean look and very easy to install.I am not into mixing music so i wouldnt know how they react, they do have a seperate low end dial and a high end dial on the back, so can be adjusted manually.I personally Would definately reccomend them to a non recording/Gaming studio setup.

Speak about Speakers
Honestly these totally exceeded my expectations, I’ve been around some noises in my time and lemme tell ya these have got some good noise to them! Really easy to set up but buy yourself 2 of the chonky mic style AUXs if you plan to hook these up to an audio interface as the small ended AUXs provided are mostly useless. But once hooked up to said interface with the proper AUX wires these things have some brilliant sound. If you’re on the fence defo come down off that fence and give these bad boys a whirl!

there's a "wake up" timer
The sound quality is ok. It's not outstanding but it's ok. Where this product fails in that it can take 3 to 5 minutes to go from output of zero volume (browsing the web with no sound for a few minutes), to wanting to watch a video clip. Then the sound doesn't come through the speakers until a few moments, or going back and forth between things with definite sound (mp3's/you tube) then it'll come through. This is a major product fail. I've only kept them as I couldn't be arsed with the hassle of sending them back. It's more annoying that you think you'd be ok with. Don't get these, get something that actually works instead. M-Audio were a go-to option for studio sound in the 2000's -2010's, now it's an Avoid. Sad times.

Would buy again !
Great ! Really good sound and more than enough power for a home studio. The cord connecting the two speakers could have been longer. Other than that, almost, perfect.

Value for Money Studio Monitors for Small-Scale Audio Production
The M-Audio BX4 studio monitors are an excellent budget-friendly option for beginners and home studios. They deliver clear mids, crisp highs, and controlled bass that works well in small rooms. The sound is balanced enough for music production, podcast editing, and casual mixing, though deep bass lovers may want a subwoofer. Their compact design fits easily on a desk, and the front bass port helps with placement near walls. Multiple input options and a front headphone output add convenience. Overall, BX4 monitors offer great performance, ease of use, and solid value for small-scale audio production.

M-Audio speakers. Great value
They sound really good and have the key features required for a desktop system: Front panel On/Off/Volume control and headphone outlets. The Microphone input is a convenience, but probably won't be used for serious work.On the rear is the stereo RCA and 6.25mm connectors, so the speakers can be used for other functions, eg plugging in a keyboard or guitar. Also present are small Bass & Treble tone controls. A convenient feature is a switch to set the box with the controls as the left speaker or the right speaker, which allows for better flexibility in setup.To get better sound than what one gets from the computer built-in sound, I spent a measly $30 on a SoundBlaster USB to analogue converter, into which the speakers are plugged.The speakers could do with some kind of grill covering the drivers and really benefit from foam pads to sit on, which help reduce resonance and angle the speakers better (all speakers should have this)

versatili e potenti,buona costruzione generale
Arrivate in anticipo,nessun danno,imballaggio a prova di deficente.Il prodotto e' ben realizzato e anche se non pesante nel complesso sembra resistente.Dopo aver letto tutti i commenti,anche quelli non in italiano mi ero convinto a prenderle ma......non mi aspettavo tale potenza,ne' da un'amplificatore integrato a questi prezzi ne' tantomeno da un woofer di neanche 12 cm,premetto che ho costruito casse acustiche HI-FI per molti anni e quindi parlo per esperienza diretta,il basso e' piuttosto profondo ,il reflex fa il suo dovere dando al piccolo woofer una precisione ed un suono potente ed indistorto anche a meta' volume....chi qui ha detto che alzando il volume distorcono probabilmente voleva sonorizzare il teatro Alla Scala di Milano perche' in una stanza di piu' di 25 mt. quadri a meta' volume sei alla massima potenza che per logica mettersti per "ascoltare" musica e anche se non si puo' parlare di high end se la cavano benissimo con diversi generi anche la classica sebben piu' inclini a pop rock o jazz,anche le voci sono belle,i controlli poi sono ben fatti,addirittura con gli "scattini",un vero lusso per il prezzo.Darei un paio di consigli al costruttore.....il mini jack per la cuffia frontale sarebbe meglio farlo a 6,3 mm,sarebbe piu' affidabile,il top ,anche per qualcosa di piu' da pagare sarebbe l'amplificazione con l'accensione automatica e la presa cuffia che invece che essere amplificata,fosse passiva e cioe' direttamente con l'audio del pc in questo modo e' vero che chi ha cuffie dure ne soffrirebbe ,ma in compenso non si sarebbe obbligati ad accendere l'amplificazione per sentire cio' che arriva dal pc.Ho dato 5 perche' se lo meritano.Una mascherina,giusto per bellezza penso sarebbe gradita ai piu' ma e' giusto un dettaglio anche perche' sono belle da vedere..consiglio per tutti......non mettete la cassa attiva vicino ad alcuna sorgente radio....soprattutto il telefono che sia di casa o altro ,ne soffrono,infatti stavo per segnalare un problema nella recensione,come difetto di ronzio costante piu' uno ogni tanto ,ma spostando l'attiva il problema si e' risolto.
