Behringer have updated their Truth monitor range to offer two models, the BA reviewed here and the larger BA. Both are ported, active two-way nearfield systems, the main difference being that the BA has an 8. Like the earlier Truths, both drivers are set into a moulded baffle trim that incorporates a tweeter waveguide to control directivity, and both drivers are magnetically shielded for use near TV monitors or the few antiquated glass CRT computer screens not currently awaiting disposal at a car-boot sale. You might not get natural cherry-wood veneer, but the overall impression is smart. The port exits comprise separate slot-shaped moulded inserts set into the baffle on either side of the tweeter. They wake up almost instantly on receipt of an audio signal.

The scandalous amount of knockoffs they produce range from guitar pedals to mixers, and yes even studio monitors. The German part is mostly gone from Behringer, who were early adopters of outsourcing to China. In they completed their own factory in Guangdong tastefully called Behringer City. Knowing them they probably ripped off the floor plans from Foxconn City. Components: Waveguide Tweeter Tweeter is a 1 inch titanium dome with a built in grill and a waveguide that surrounds it.
The waveguide is supposed to direct the sound forward and match the dispersion pattern of the woofer. A bit different from a horn which has the dual function of pattern control and making sounds louder.
Stickers claim 50 watts RMS power handling and 8 ohm impedance. Woofer The Behringer Truths got a little dusty waiting to be reviewed. The woofer cone is made of some polypropylene type plastic, and the tiny dust cap is very soft and prone to denting. The surround is a stiff butyl rubber. The specs say bass rolls off at 50Hz, and this driver should have no problem hitting that mark. This sticker that has some specs on it is pretty fancy given that the BA speakers are not meant to be taken apart.
Note the vented pole piece for lower heat buildup, which makes for less distortion and improved power handling. Amplifier Behringer includes a large manual along with the Truth BA speakers, but everything you need to know is painted right on the back of them. Note that the -6db for Room Compensation, even though indicated by the markings is not available in the movement of the switch.
Everything else worked as advertised and is probably easier for you to read from the image than for me to retype. I know I was awe struck by this sight for at least a good 5 minutes. Cabinet Prepare for more insanity. MDF quality is very nice dense stuff, not the usual chinesium crap.
This is a better box than the Infinity Primus, which was over built massively for the price point. Port The two ports flank the tweeter in an arrangement I have not seen in anything else except the Genelec.
The ports themselves seem like thick enough plastic to stay put and not break. I have no idea how these are tuned given bizarre shape and 7 inch depth. Running balanced cables to the monitors gives a clean signal and enough gain to drive a train. The wide baffle means that more of the sound that the speaker is producing is being projected forward.
This gives the effect of more music at lower volumes when you are sitting right on top of the speaker in the near field. The speakers are doing the waveguide thing and not projecting any image outside of the width of the speakers. I give up all hope of coupling with the room and toe the speaker a little to try and hit more of the direct sound on the side of my face. Putting on a familiar test track I hear the midbass is a little thick in the flat setting.
Reading the thourogh documentation on the back of the speaker I adjust the bass -4db for the close slammed to rear wall placement and noticed the -6db, even though indicated by the markings on the back of the box is not available in the movement of the switch.
There is a bump around Hz that gives a tactile sensation for kick drum material. The bass is very tight, and extremely defined. There is no mistaking the bass guitar for a bass drum. The highs are too much, just a little too live, and maybe slightly on the harsh side.
I think the metal dome and waveguide are the culprits, but it could be cone break up from the large woofer. I will need to wait for close mic measurements before I can find out. Separation of music elements is great, and acoustic guitar clarity is a little overdone.
I would like some more bass gain from the wall to compensate, either that or a little less treble. On the plus side there is a shit ton of clarity. Extremely clean amplification, zero cabinet issues that I can hear, and the whole package is all very impressive for such a relatively unassuming pair of speakers. The Truth monitors are living up to the hype. While listening through a few other tracks the treble starts to bother me.
Not just the quality, but the quantity. Turning again to the literature on the back of the speaker it suggests for a live room, which I definitely have, to knock down the treble 4dB. I give that a shot, but it sounds too muffled.
I flip the switch to -2dB, and the clicks and pops of Kraftwerk are now mostly enjoyable instead of anoying. These speakers are sounding acceptable now. The Behringer Truth monitors are providing a viseral emotionally ready connection. Just bring your tunes and strap in. Measurements: This is the on-axis frequency response of the speaker measured outdoors. Looks like I was either a little off axis, or wind noise rejection cut the response above 12kHz.
There are some chunky peaks around 6kHz and 11kHz, as well as some serious nasty bits in the Hz range, and a hump at hZ. Here is the off-axis response of the speaker from degrees in 15 degree increments. Drop off looks pretty uniform, which is a credit to the waveguide doing its job.
This is close mic measurements of the drivers. This speaker has switch on the back to cut off either the woofer or tweeter, so there is no interference between drivers in this measurement. The woofer has a null at Hz and peak at Hz. This anomaly is visible in all of the measurements so far. This could be from sound leaking through the pole piece venting and dust cap to cancel out the sound, or it could be diffraction effect from the surround of the woofer, or something else all together.
Ports are putting out a good bit of content in the 30Hz range even though there is not much happening with the speaker at this range, and leaking sound between Hz. Retarded, and 2. Getting in the way of the speaker doing its best. Instead I had to disassemble the tweeter driver itself. What I found was surprising. There was not just a metal grill, but also a little circular piece of cellophane tape in the middle of the grill that acts as a diffuser.
I hate diffusers too, so this is modification double plus good in my book. Just make sure you line up the holes with the posts on the motor when putting everything back together. World class bad ass, letting that titanium get some air. Not only do the speakers look good now, they measure better as well. This is 2 sets of measurements, far and close micing of the tweeter with before and after removing the grill.
Removing the grill smoothed out the tweeters response considerably. Modified Listening Impressions: The sound better to me, especially near field. They seem to have gotten a little louder, but also smoother sounding. I think this modification is well worth it if you are sitting close to the Truth Monitors.
Yes I am pushing 16dB of bass boost below the port tuning of the speaker. This does mean that the speaker is more likely to over extend the woofer, but the -3dB point is 28Hz now and that is something very interesting. How did I get away with this, well there are a couple of things. The speaker is very sensitive to gain, especially when using balanced connections, and has a nice low noise floor. The next reason is that these speaker are proper fucking loud.
They are speced by Behringer to play dB at 1 meter without distortion. That means that with this bass boost you will be limited to only dB, which is still really fucking loud.
The rest of the corrections are minor tweaks getting rid of harshness here and there that either showed up in measurements or in listening. Corrected Listening Impressions: With the grillless tweeter and 29Hz bass extension this speaker is surprisingly not that different than it was for most music.
Bass is a little less punchy and instead deeper. Music is a little more clear, and a little more smooth, and a little more refined. Not only that, midbass clarity is not compromised by the added extension. Even in movies the bass is smooth and understated, not a rumble clusterfuck that you get from floppy bass cannons.
If you are planning for desktop use keep in mind that the Behringer Truth BA speakers are huge, and were too big for my tiny desk to get the best imaging. Placement is going to be a balancing act of compromise, but if you want loud, well built, clean speakers, these fit the bill.
Behringer Truth B2030A
Paras vain olikin se, joka oli ennakkoasenteiden mukaan joukon huonoin. Suosio alkoi kalottidiskantillisesta mallista BA, joka on jo aikaisemmin testattukin. Kokoero, onko se oleellinen? Behringer on studiopuolelle panostava merkki. Kotiteatteri on helpompi paikka. Varta vasten musiikkia varten pyhitetyt tilat ovat nekin helpompia kuin olohuoneet.
