DAS Audio Action-512A B-Stock

I tested the FBT Vertus CLA 604A as a compact column solution for small-to-medium events where clarity and controlled coverage matter more than chest-thumping bass. I used it for spoken-word events, acoustic sets, and as front fills on a few small club nights - that perspective guided how I judged its strengths and limits.

First Impressions

The CLA 604A immediately communicates a design focused on intelligibility and modularity - the column is narrow, light, and feels engineered for installations where discreet aesthetics matter. My first setup was quick - the column is noticeably lighter than typical powered speakers of comparable claimed power, and the rear control panel is straightforward with volume, presets, high-pass filter, and mic/line switching that made quick on-site adjustments easy. I appreciated the built-in DSP presets when I switched between live acoustic material and PA-micled speech, and the physical build - extruded aluminium with a powder coat and a sturdy grille - felt robust for repeated handling.

Design & Features

The 604A is a bi-amplified 2-way column with six 4-inch neodymium woofers and four 1-inch neodymium tweeters arranged for a 100° x 20° dispersion pattern - that translates to wide horizontal coverage and tight vertical control. It uses Class-D amplification with roughly 400W RMS for LF and 100W RMS for HF, a built-in switching PSU, and an onboard DSP offering four EQ presets plus a high-pass option and mic/line sensitivity switch. Physically the unit is 130 x 841 x 130 mm and ships with a 5-meter IEC power cable and XLR signal input with link, plus Powercon loop outs for chaining units - all handy for modular array setups or quick multi-speaker rigs.

Build Quality & Protection

Handling showed FBT prioritized lightweight construction without feeling cheap - the extruded aluminium cabinet is rigid and the powder coat resists scratches better than typical painted plastics. The grille is solid metal, and the connections - XLR in/loop and Powercon - are recessed and positioned to minimize visible cabling. The only small gripe was that the latching hardware for stacking modules feels functional rather than elegant - it works well, but you can tell it was designed for workshop installation rather than frequent on-the-road assembly.

Comfort & Portability

At about 9 kg the 604A is easy for one person to carry and maneuver; it feels markedly more portable than traditional two-box monitors while still offering substantial SPL for its size. I transported it to multiple venues without needing a flight case for single-unit use - a padded bag is fine for short runs - and the slim footprint makes it easy to place on stands, wall mount, or combine into longer arrays when required.

Sound Quality

In practice the CLA 604A excels at midrange clarity and vocal intelligibility - speech and singer-present acoustic performances cut through room reflections cleanly. The high end is crisp without being brittle, and the DSP presets let you tailor presence and low-end roll-off effectively for live voice or music. Expect limited deep bass - the lower -6 dB point is around 130 Hz - so the speaker works best paired with a subwoofer if you need full-range impact for bass-heavy material or dance music.

Real-World Experience

I used the 604A across spoken word nights, acoustic duo gigs, and as front fills for a small DJ night; its strengths were most obvious on speech and acoustic instruments where clarity and even horizontal coverage matter. On a pair of units flown or on stands the audience field was well covered without the harsh vertical lobing that column speakers sometimes create, and chaining multiple CLA 604As with the power/data loop made it simple to scale coverage. For a DJ set without a sub the lack of low bass was obvious - the unit kept transients tight but didn’t provide the body needed for electronic basslines.

The Trade-Offs

The main compromise is low-end extension - 130 Hz means you will need a sub for full-range music that relies on bass. The speaker is also optimized for projection and voice - if you need a warm, chesty tone up front you may find it lean without complementary low-frequency reinforcement. Lastly, while it is modular and expandable, the latching system and close-packed drivers mean alignment matters - improper angling in multi-module rigs can introduce uneven vertical coverage.

Final Verdict

The Vertus CLA 604A is a thoughtfully executed column PA that I’d recommend to houses of worship, corporate AV, acoustic performers, and mobile rigs that need clear coverage with minimal visual impact. It combines intelligible mids, flexible DSP presets, and convenient connectivity into a lightweight package - just be prepared to add a subwoofer when you need real low-end impact. Overall, if your priority is speech clarity and controlled audience coverage in a compact footprint, this is a strong contender.

I spent several weeks running the FBT X-Pro 112A through rehearsals, small gigs and a few quick installs, and came away impressed by how much headroom and clarity FBT packed into a compact 12-inch enclosure. I approached it as a working gig speaker - something I could use as FOH for a duo, a monitor for a trio, or a flown cabinet for installs - and that practical viewpoint shaped everything I listened for.

First Impressions

Out of the box the X-Pro 112A feels solid and purpose-built - the plywood cabinet has a restrained, professional finish, and the rigging points and recessed handle tell you this is meant to be used, moved, and mounted. Powering it up for the first time I immediately noticed the tight low-mid response and a surprisingly clean top end for a 12-inch two-way at this price and size.

Design & Features

The X-Pro 112A is a two-way, bi-amplified design built around a 12-inch LF driver with a 2.5-inch voice coil and a 1-inch compression driver on a rotatable 80 x 50-degree horn. FBT equips it with a Class-D power section specified at 1200 W for LF and 300 W for HF, on-board DSP with four presets and a three-channel mixer that covers two mic/line inputs plus Bluetooth for a third channel. Physical touches include a 35-degree monitor bevel on one side, a 35 mm pole flange, M10 rigging points and an IEC mains inlet - details that make it useful for both portable and installed applications.

Build Quality & Protection

FBT uses a plywood enclosure with an anti-scratch coating and internal reinforcement, and that shows in real use - the cabinet resists dents and the grille stayed true after a few hurried load-ins. The recessed aluminum handle is comfortable for carrying short distances, and the M10 points and beefy pole mount give me confidence when I need to fly or pole-mount the box.

Comfort & Portability

At roughly 18 kg (about 39.7 lbs) and with a single recessed handle, the X-Pro 112A is not featherlight but is very manageable for one person for short moves and two people for longer hauls. Its compact footprint and pole-mountability make it easy to place on stands or on stage as a wedge, and the bevel option means it behaves acceptably as a monitor in a pinch.

Controls, DSP & Connectivity

The on-board mixer is straightforward - two mic/line channels with XLR/TRS options and a Bluetooth channel for streaming - and the four DSP presets give quick voicing options like Live, Vocal and Club. I found the presets useful as starting points, and the limiter/LED indications are practical for protecting the drivers during loud passages. For linking I used the XLR mix out to feed a sub and the speaker kept phase and timing coherent through the crossover region.

Real-World Experience

I used the X-Pro 112A as FOH for an acoustic duo and then as a monitor for a three-piece band; in both roles it delivered surprising low-end presence without sounding woolly, and vocals sat in the mix clearly when I selected the Vocal preset. It reaches comfortable club levels for small to medium rooms - the quoted peak SPL is a solid number in practice - and the Bluetooth pairing was reliable for quick background tracks between sets. The speaker responds well to EQ tweaks, and I appreciated the rotatable horn when switching from main-mono to monitor duties.

The Trade-Offs

There are a few compromises - the built-in mixer is functional but not as flexible as a dedicated desk, and if you need extended sub-bass you will want a supplemental subwoofer because the low limit is around 50 Hz, which is fine for most live music but not for low electronic sub tones. Also, while the speaker is rugged, the single handle placement makes long carries less comfortable than cabinets with multiple grips.

Final Verdict

The FBT X-Pro 112A is a thoughtfully engineered active full-range box that balances power, clarity and practical features in a package that works for gigging musicians, small venues, and installers. If you want a single-speaker solution that can act as FOH, a monitor and an install-friendly cabinet with modern connectivity, the X-Pro 112A is a compelling option - just plan to add a sub if you need deep club-level low end.

I spent several weeks running the DSP 110 as mains tops for rehearsals, small pub gigs, and DJ sets so I could get a real feel for how these 10-inch active speakers behave in live situations. From where I sit - needing lightweight, affordable, and flexible PA - the DSP 110 delivers a lot of useful features in a compact cabinet, though it also shows a few trade-offs when pushed very hard.

First Impressions

The first thing I noticed was how solid the cabinet and connectors felt for the price - the housing is a sturdy plastic with integrated handles and a pole flange that makes quick setup easy. Power-on reveals a bright, clear top end and a surprisingly full low-mid from the 10" woofer, but you can also hear a faint system hiss at idle and the rear cooling fan becomes noticeable in quiet venues or on low-volume monitor use. Setting up the built-in DSP presets (Music, Live, Voice, DJ) is straightforward via the push-rotate master control - I appreciated being able to dial in low-cut and three-band EQ quickly without an external processor.

Design & Features

Physically the DSP 110 is compact (298 x 523 x 307 mm) and reasonably light at about 13 kg, which makes it manageable for one person to carry and set on a stand or wedge on stage. The rear panel gives you two balanced XLR/¼" combo inputs plus a 3.5 mm auxiliary and an XLR mix output - everything I needed for a singer plus keyboard or laptop, and the DSP functions are controlled by the single rotary/master push button with a small display. Internally it uses a Class-D amplifier, the transducer layout is a 10" woofer plus a 1" compression driver (1.4" voice coil), and the spec sheet quotes 250 W RMS (1,000 W peak) with a quoted max SPL around 132 dB - plenty on paper for small-to-medium rooms.

Sound Quality & Tone

In practice the DSP 110 has good presence and is very usable for vocals and backing tracks - the high frequencies are clear and vocals cut through when you choose the right preset or tweak the mid/high EQ. Low end is stronger than you'd expect from a 10" box and works fine for acoustic and electronic music when paired with a sub, but without subs the bottom end can feel a bit rounded rather than tight and punchy compared to higher-end models. At club levels I heard the DSP limiting behavior - when driven very hard the speaker's DSP/matching limits dynamic headroom, which can make the sound seem compressed at absolute maximum SPL.

Comfort & Portability

Carrying these around is easy - the handles are well positioned and the weight is far less than comparable 12"/15" boxes. The pole flange is solid and the cabinet sits well on a stand without wobble; as a mobile operator I liked that two people can move a pair in the back of a small car without drama. If you need battery operation, note this model requires mains power - there is a battery variant in the DSP family, but the standard DSP 110 runs on mains only, so plan for cables and power access at venues.

Real-World Experience

I used the DSP 110 for singer-with-keyboard setups and for DJ parties up to roughly 120-150 people when augmented with a subwoofer, and the speakers held their own with clean mids and a detailed top end - I rarely felt like I was short on level. On purely vocal-fronted gigs I found the Voice preset and a moderate low-cut to be the quickest route to intelligible speech, while the Music or DJ presets gave a thicker, more club-friendly balance. Two practical annoyances I ran into were the audible rear fan in very quiet monitoring scenarios and a subtle hiss when the inputs were at high gain and music was stopped - neither problem was deal-breaking for gig work, but they are worth knowing about for intimate acoustic settings.

The Trade-Offs

There are compromises - you pay a lot less than top-tier brands, but the DSP handling and limiting can make the last few decibels feel compressed and slightly masked compared with higher-end boxes. The fan noise and idle hiss I mentioned are audible in quiet venues or when used as a stage monitor, so if you need pristine silence at low levels these aren’t the ideal choice. Also, the mains-only design (230 V nominal supply in the spec) means international voltage considerations matter - check power compatibility for your region before assuming plug-and-play.

Final Verdict

Overall I came away impressed for the price - the DSP 110 is a practical, punchy small PA speaker with helpful onboard DSP and enough output for many small-venue and mobile-sound situations when paired with a sub. I recommend it to working musicians, small DJ rigs, and mobile operators who want a lightweight, affordable active top and who accept the minor quirks (fan noise at low levels, DSP limiting at absolute max). If you need the last word in clarity at stadium SPLs or ultra-quiet monitoring for acoustic duo work, look higher up the ladder - but for value-per-pound the DSP 110 is hard to beat.
