8" (20cm) Type-R Subwoofers (4Ω + 4Ω) - SWR-8D4

Aceste subwoofere Type-R , generatia V , au noi caracteristici avansate pentru a obtine un bass mai curat , mai profund , mai rapid , mai precis si au chiar si o putere mai mare dacat inainte.

Speaker Rating:

  • Max RMS Power Capacity: 350W
  • Peak Power Capacity: 1000W
Informatii despre produs

Bass extrem care incape in mai multe locuri

Subwooferele Type-R au fost reconstruite in intregime pentru a oferii o flexibilitate mai mare la instalare. At 115 mm of mounting depth for the 8” (20 cm) this new design offers even greater output capability.

O excursie mai mare = Mai mult SPL

Noua structura " FEA-Optomized Motor " impreuna cu constructia revolutionara a suspensiei " High-Amplitude Multi Roll (HAMR) " ofera noilor subwoofere Type-R cel mai mare X-max si SPL din categoria lor. Cu un X-max de 12mm noile subwoofere Type-R ofera cel mai bun bass , distorsiuni foarte mici si sunet de o calitate fara concurenta in clasa lor.

Mai multa putere = Mai mult control

Starting with a new ten piece, segmented magnet structure, the new Type-R subwoofers deliver more accurate, louder and cleaner bass with even more control. This new magnet assembly is also an integral part of the next generation of Alpine’s Patented Radial Vented VC cooling system.

"Keep it Cool = Keep it Playing"

Radiatorul patentat Alpine "Radial Vented VC" si sistemul Airflow Management (US Patent #7,634,101) ajuta la minimizarea compresiei puterii si asigura un timp lung de redare prin eliminarea activa a calduri produse de bobina. Noul cadru din aluminiu este folosit ,in intregime, si ca radiator pentru a permite o redare sustinuta chiar si in cele mai extreme aplcatii.

Optimizat FEA = Liniaritate maxima

Geometria polilor " Compound Radius Curve " , patentata Alpine , asigura un camp magnetic ultra simetric , in timp ce optimizeaza densitatea fluxului pentru a reduce semnificativ distorsiunile , de asemenea ajuta la imbunatatirea puterii.

Putere mai mare

The oversized 38 mm voice coil allows for increased power handling of 350W RMS / 1000W Peak.

Pentru a obtine cele mai bune performante va recomandam sa folositi subwooferele Type-R impreuna cu noile amplificatoare digitale PDX.

4 Tehnologii unice Alpine

1. Cadrul HAMR optimizat FEA

Constructia cadrului "High-Amplitude Multi Roll" permite excursii extreme fara a reduce suprafata conului. Optimizat FEA pentru liniaritate si facut cu Santroprene™ , cadrul HAMR este o parte importanta in sistemul de suspensie care permite excursii extreme cu control precis si fara distorsiuni.

2. Spider optimizat FEA

Asigura controlul firului leonic pentru a elimina orice zgomot mecanic sau interferente tipice constructiei pentru excursii mari.

3. Redial Vented VC Heat Sink & Airflow Management System

Gestionarea activa a temperaturii bobinei prin fortarea aerului direct peste radiator.

4. FEA Optimized Machined CRC Motor Structure

Creaza un camp magnetic simetric in timp ce optimizeaza densitatea fluxului pentru a reduce distorsiunile si in acelasi timp pentru a creste puterea.
