DAS Audio Action-512A B-Stock

I spent several weeks running the Seeburg Acoustic Line GL24 dp as front-of-house and fill speakers for a mix of corporate gigs and small festival stages, and what struck me first was how predictably the system throws - focused vertical control with a surprisingly full midrange presence. I approached the GL24 dp looking for a reliable, deployable column solution that would keep vocals intelligible in acoustically difficult rooms while offering enough headroom for live music when supported by subs, and overall it delivered on that brief.

First Impressions

Getting the GL24 dp out of the truck is straightforward enough for a single person to handle the cabinet, but its tall, slim profile and 22 kg weight mean you notice it when you set it on a stand or carry it through tight doorways. The finish and Baltic birch construction feel industrial-grade and the connectors - XLR in/thru, PowerCon in/thru, Speakon out and Ethercon - are exactly the pro-level choices I wanted on a rig that I know will see repeated installs. Powering it up and cycling through presets showed a sensible DSP layout and clear presets for speech, music, and flown configurations, which made dialing in takes and rehearsals fast.

Design & Features

The GL24 dp is a two-way, digitally powered column system with six 6.5 inch neodymium woofers coupled with 24 1 inch neodymium high-frequency drivers arranged into a cylindric wave radiator - that driver complement is what gives the GL24 its narrow vertical and wide horizontal dispersion. Internally the cabinet contains a 2 x 800 W AES bi-amped power section and an FPGA-based DPLMx 32-bit floating point DSP with 24 bit/96 kHz AD/DA conversion and very low latency, which together mean the presets and voicing behave predictably across input types. Rigging-wise it includes nine M10 flying points and a 35 mm pole flange, so it is ready for flown arrays or stand use, and the polyurea-coated birch plywood cabinet survived the real-world knocks I put it through with minimal cosmetic wear.

Portability & Handling

At roughly 106 cm tall and about 22 kg, the GL24 dp is not featherlight but remains manageable for a single, confident tech; two people is ideal for safe rigging and stacking onto subs or pole mounts. The built-in handles are placed so you can get a firm grip, but because the cabinet is tall I found it easier to use a small two-person routine when moving between stages. The inclusion of power and signal thru connectors reduces cable clutter and makes multiple-box setups much faster to deploy.

Real-World Experience

I used the GL24 dp for spoken-word presentations in a 300-seat corporate hall and then as a left/right flown pair with subs for a 600-person outdoor evening slot, and the consistent takeaway was clarity - speech was intelligible at the rear seats with no harshness up front. For full-range music I quickly discovered what the specs hint at - the system has limited low-end extension below about 80 Hz, so pairing with good subs is essential if you want full-bandwidth music reproduction and impactful low end. On the positive side, SPL and headroom were impressive for a cabinet of this size - the system comfortably reached high levels without audible compression when I needed it to, and the narrow vertical dispersion kept reflections to a minimum in treated and untreated rooms alike.

The Trade-Offs

The main compromises are familiar: the GL24 dp excels at clarity and reach but is not a substitute for a sub-heavy PA in dance or bass-forward applications, so budget for subs if music is a core use case. It is also a premium product in build and capability, which means the purchase price and vendor availability can be a hurdle for smaller weekend-only operators, and the tall cabinets need planning for transport and rigging. Finally, while the onboard DSP presets are solid, serious fine-tuning for complex rooms benefits from an engineer who knows how to integrate line-array behavior with subs and delay stacks.

Final Verdict

After a month of mixed-use testing I came away impressed by how consistently the GL24 dp controlled vertical dispersion and delivered intelligible, clean sound across speech and band settings - it does exactly what a pro column system should do. I recommend it to houses of worship, corporate AV teams, touring acoustic acts, and rental companies that need a deployable, high-headroom column box that integrates into AES67 networks and modern digital workflows; just plan on adding subs for full-range music and a suitable rigging workflow for repeat installs.
