Engineered for extended low frequency response and flexibility, the 12SW-4HE 12” high excursion subwoofer from GRS is an ideal replacement driver for existing subwoofer systems or an excellent choice for new economical designs. Capable of producing powerful bass response in both sealed and vented designs, the 12SW-4HE is suitable as a drop-in replacement for most existing 12” subwoofers. The rigid paper cone is supported by a large diameter spider and rubber surround to keep excursion linear while providing reliable performance.

With a high temperature 2” voice coil wound on a thick aluminum former the 12SW-4HE can comfortably handle up to 250 watts RMS of power.

Capable of incredible low frequency extension, the GRS 12SW-4HE is the perfect driver for true bass on a budget.

Alles Super

Läuft sauber. Große Auslenkung.

By Johannes on 25 August 2026

it is AMZING for the price, reproduces deep bass with power, and its very loud and clear sounding! I would strongly reccomend

By Szilvia on 24 August 2026

Very good replacement driver for my Dali Concept sub. Solid rubber surround, though maby a little heavy (4 ohm) for the onboard amp (160W RMS). The original driver had foil surrounding. Delivery took only 3 days which is exelent.

Da die Lautsprecher nicht verfügbar waren, hat die Lieferung knapp 3 Monate gedauert. Nachdem die Lautsprecher verfügbar waren, waren sie sehr schnell bei mir. Nach ca. 2 Monaten hatte ich eine Emailanfrage nach Lieferdauer gestellt, die nicht beantwortet wurde. Deshalb nur 4 Sterne.

Uitermate tevreden , geeft volle ook 'rollende' echt lage tonen !!

By Dick on 29 December 2025

As always sound imports deliver fast. I have used the 8inch version of this subwoofer and is very good. Now I said to make use of the 12 inch power. It should play well in a 70 liter ported box or bigger, depending on the tuning frequency.

Estoy entusiasmado por la compra del subwoofer GRS 12SW-4HE, estoy terminando de fabricar el cajón donde va ubicado y espero que tenga tan buen resultado como sus características y especificaciones, es un poco bajo de SPL 84dB pero tiene otras condiciones muy buenas como Fs que tiene un rango de 24Hz y su Xmax de 12'5mm , su rango de respuesta de 4ohmios y su potencia lo hacen especial. Tengo ganas de oírlo. Muchas gracias . Decir que he encon...

Nice quality. Quick as expected

Die Treiber haben meine Erwartungen übertroffen. Habe daraus zwei Woofer mir Bassreflex gebaut. Abgrundtiefe saubere Lösung.

By Martin on 28 October 2025

excelent subwoofer I use in closed box 40x40x40cm with linkwitz transform circuit , or use DSP , otherwise falling from 60Hz down

By Ivan on 28 October 2025

Lautsprecher genau wie beschrieben Super teile

By Ingo on 13 October 2025

Habe meinen alten Subwoofer- Tieftöner ersetzt. und bin vom Ergebnis angenehm überrascht. Der Tieftöner ist impulsiiv und klingt ordentlicch. Er könnte vom Tiefgang etwas besser sein, jedoch liefert er für diesen Preis eine ordenliche Vorstellung.

This little toy shakes my house in a 105L enclosure with a port tuned to 19Hz, reaches down to 10Hz

By Benjamin on 4 August 2025

replaced a blown woofer, this sound imports woofer has a deeper bass than the one I removed.

By Terrance on 17 July 2025

I think it is good value for the money, but have not tried the speaker yet

By Jørn Lindquist on 24 June 2025

Built the sub in a 110L ported enclosure tuned to 22Hz, and it easily goes down to 20Hz with barely any loss in volume (especially when paired with a DSP or EQ). High excursion and volume with minimal distortion, for the price, it's a beast!

By Marijn van Beek on 9 April 2025

This subwoofer is the best you can get for the price. I build a custom vented box of 105L with a 220cm2 vent tuned to 25hz and it is amazing. The amout of bass this subwoofer can create (30hz@100db) is crazy, definitely seen the cheap price. I would recommend this to everyone

A good budget speaker that handles low frequensies well. In my flat and with my 4ft^3 20Hz vented box it goes rather easily under 20Hz. I don't listen to music at high volume so don't know how it handles loud sounds.

To be honest its a nice subwoofer. But.. As advertised it should go as low as mid 20s, not in real life. It doesn't play anything below 30. Also it has some distortion when pushed well! Easy to tune.

By R1 Rob on 1 June 2024

Degelijke subwoofer die heel laag gaat!
