Lodging only a solitary eight-inch driver secured by a steel grille, the sub is genuinely minimized and simple to lift with one hand by means of its indispensable convey handle. A spine at the base stretches out forward of the bureau to build steadiness, and once amassed the sections have a sense of safety. In any case, similarly as with any such ‘opening together’ line exhibit, I dread what may occur if a plastered individual from the group of spectators were to fall onto it, as I question the couplers could endure much misuse given the measure of influence coming about because of such a long, limited structure. sub zero speaker box diagram

As is ending up progressively regular with dynamic PA speakers, essential blending offices are worked in to take into account remain solitary use when just a few data sources and maybe an extra support track feed are required. Sited on a calculated board at the highest point of the sub, a couple of combi XLR/jack information sources can be exchanged for mic-or line-level sign, and every ha its very own volume control. There’s no apparition control so it is an instance of dynamic mics or battery-controlled electret mics as it were. A third information, additionally with a volume control, is gotten to by means of stereo RCA phonos or a TRS smaller than usual jack and works at line level as it were. This would ordinarily be utilized for playback gadgets however could likewise be utilized to enter a console or other line-level instrument utilizing the fitting connector. A two-band EQ can be utilized to tailor the general PA sound, and there’s a XLR yield that conveys the blended sign for connecting to a subsequent framework. There’s no ace volume control, however with just three information sources that is no incredible misfortune.

So far then we have a minimal and famously reasonable framework with a medium power rating that is light and extremely fast to collect. In any case, the main thing is the manner by which well it performs in its given applications. An arrangement of this size and power is probably not going to be capable when working with a full band that incorporates acoustic drums. A more probable situation is that the framework will discover support with solo specialists, pairs or predominantly acoustic gatherings not expecting to intensify a great deal of low end, where the SZPA-L68’s cited most extreme SPL of 114dB will get the job done.

Testing

In the wake of checking recorded music playback, which the framework dealt with well at moderate levels, I took the SZPA-L68 to a bar gig where the trio in which I play was performing. We utilize one electric guitar, one acoustic guitar, a cajon and two vocal mics, with the vocals, the cajon and a DI feed from the acoustic guitar amp all experiencing the PA. It was one of those fairly confined gigs where the vocal mic wound up nearer to the speaker than we’d like, however straight away the SZPA-L68 intrigued with its protection from criticism.

To accomplish a fresh vocal sound I moved off only a tad bit of the low end and included a trace of top the two-band EQ, nourishing the line contribution from our own little blender with the EQ set near level. Acoustic guitar came through with respectable definition while a valuable measure of weight from the cajon got through the woofer. It is likewise worth remarking on the wide flat inclusion, which served us well in what was a fairly strangely molded bar. sub zero speaker box diagram

Tuning in from a group of people point of view, the sound came over as clear and all around offset with a lot of level for our needs. We can get entirely uproarious on events (given our no-drums position) however the speaker kept up. From an entertainer’s point of view behind the section, the speaker sounded to some degree sloppy as next to no in the method for mid/high data discovers its direction rearwards — which is as it ought to be. That implies some sort of screen is fitting; we utilized our ordinary Mackie SRM150 to give us some sort of lucidity. Setting up and pulling down was truly simple, however the mounting shoes were somewhat solid (being fresh out of the plastic new), yet exhibited no genuine issues.

In such a little setting it was additionally of advantage having such a thin speaker as it doesn’t hinder the group of spectators sight lines about to such an extent as a regular box speaker. Any reasonable person would agree that all the more exorbitant line exhibits will more often than not convey progressively level and more noteworthy tonal exactness — I found that material with a ton of HF substance could begin to sound a touch scratchy on the off chance that you truly pushed the levels — however given its extremely minimal effort, there’s very little to grumble about here. It absolutely merits a more critical look in the event that you need something compact for a performance demonstration or team playing littler scenes.

Greater Is Better?

In the event that more power or more noteworthy bass expansion is required, at that point the bigger SZPA-L812 framework may possess all the necessary qualities, as it includes a 12-inch ported sub cooperated with eight drivers in the upper segment and packs an absolute intensity of 550 Watts RMS, delivering a greatest SPL of 120dB. It has a low-recurrence farthest point of 45Hz and an upper reach of 20kHz, with the hybrid recurrence set at around 160Hz. Feeling weightier and unmistakably progressively considerable (the general framework weight is 28kg), the sub is worked from compressed wood and, being taller than the SZPA-L68 sub, the two sections have been made shorter to keep up a comparative in general framework tallness when collected. The way the segment, which is somewhat more extensive than for the SZPA-L68, fixes to the bass bureau is through a marginally bigger shoe fitted with a hook that must be squeezed to discharge the cupboards. There’s a top handle coordinated into the woodwork making the sub a genuinely simple one-hand lift — however you might not have any desire to convey it to the extent you’d be upbeat conveying the SZPA-L68 sub.

Its control segment really offers less offices than the SZPA-L68. There’s no blender, simply left and right adjusted XLR/jack line inputs (added to mono inside), stereo out/thrus on XLRs for affixing to different frameworks, an ace volume control and a different volume control for the sub. There’s additionally an extremity reverse switch for the sub. Obviously at that point, the SZPA-L812 is intended to be utilized with a different blender.

On vocals the sound ended up being fundamentally the same as that of the SZPA-L68, but a couple of dB stronger, however when playing back tracks from my iPod, the sub put in a substantially more confident presentation. Truth be told the general nature of music playback is vastly improved than from most two-way dynamic boxes, absolutely at this finish of the value scale, where the sub figures out how to sound both punchy and all around controlled. Having various little mid/high drivers helps keep the mid-go clear, which is significant for both music playback and normal sounding vocals.

Given that the framework is fit for an extra 6dB in the SPL division and that it has a sub all the more meriting the name, it comes as some unexpected that it just expenses around 50 percent more than the SZPA-L68. So if its all the same to you giving up a little transportability, the SZPA-L812 might be the more fitting decision, particularly on the off chance that you need a framework with somewhat more heave and weight at the base end.sub zero speaker box diagram
