The Ultimate Party Box - For Indoors & Outdoors!

The McGrey SL-12/3 is the perfect party speaker, whether it’s a lively summer bash, a roaring festival party or a prom night blowout, this speaker will make walls (and tents) shake!

Not For The Faint-Hearted

A 12" woofer with two bass reflex ports delivers serious punch. In the high frequencies, a 3/4" piezo produces razor-sharp, crisp sounds. The connections come as terminals and jack sockets to ensure maximum flexibility. This means the speakers can be connected to both a PA power amp and a hi-fi amplifier.

Tough Exterior

This party box is up for anything. The sturdy wooden cabinet is covered with felt, so it’s not afraid of a little dirt and dust. A metal grille also protects the woofer from enthusiastic party guests. With practical carrying handles on both sides, it’s easy and convenient to set up or reposition.

Big Or Small, The Party Box Is A Must

But that’s not all, party people! The McGrey SL-12/3 is a powerful full-range box with balanced sound characteristics. It’s also ideal for all kinds of events, such as sound reinforcement for party cellars, weddings, birthday celebrations, or music concerts.

Eat, Sleep, Party & Repeat!

Good value for money
Review from Anonymus on 13.05.2020

First order to Kirstein - living in RO / TM in 05/05/2020 -> arrived in 1 week, even the delivery time was originally planned to take 9-13 days, so 1 "+" for DPD in due lock-down conditions.

I ordered from Kirstein / DE due to the fact the same product was out of stock in RO with August delivery date... and the price was +~ the same, including transportation.

One of the packages was received damaged - photo available on demand - with the front grill dented - speaker not damaged behind it -> this is 1 "-" for DPD and for packaging process - @Kirstein: need to add extra protection inside the package to prevent this kind of unfortunate events.
Anyhow I got them for acoustic purposes not for "beauty show".

Connected them to a Phonic Powerpod 750rw mono Monitor&Main outputs - the sound quality depends on the input and the power amplifier - the lows are a little bit limited - need to work further on equalizer settings. Electronic drums work acceptable on them.

So far a good present for me :-)

I am super satisfied! My neighbors not so much! 😁 I'm still struggling whether there will be 2 / 15s next year! But I still have to think about that carefully! But the sound is already very impressive!

Ps. You did everything right!

The speakers fulfill their purpose, have decent bass and are absolutely satisfactory for the price. Of course, you can get a lot more out of them with an EQ if you need to.
The delivery was also very fast and neatly packaged. Thank you very much.
Beautiful party box with enough pressure

Quite good sound! Must only be operated with the right (powerful) amping. Small tone control is an advantage. Then they sound quite good and also have enough pressure. As an amp I use a peavy cs800. Always consider the price!

Question by Michael on 05.09.2024

Can I also use the speakers in the rehearsal room to play instruments?

Answer by Musikhaus Kirstein:

Theoretically yes, but you need a power amplifier for the speakers to work.

Question by Daniel Hanuschke on 22.07.2019

Can the box be placed higher on a tripod (standard size)?
Are there inlets (tripod holes) in the bottom of the box for this.
On the pictures of your website is unfortunately none which shows the box from below.
A short answer would be nice.
Thank you !

Answer by Musikhaus Kirstein:

Yes, the speakers have a 35 mm speaker flange for speaker stands. Suitable stands would be for example: https://www.kirstein.de/Boxenstative/Pronomic-SPS-1S-Boxenstativ-Stahl-2x-Set-mit-Tasche.html
