JBL 2241H 18" Woofers

Posted by thetubeguy1954 (A) on September 16, 2015 at 06:39:57

Hi guys!

I'm considering building a subwoofer using two JBL 2241H drivers in one of these type enclosures:

-- Nelson Pass' slotted subwoofer
-- Linkwitz H dipole subwoofer
-- ripole subwoofer

Here's the info I could find about the 2241H drivers:

Product Specifications

Nominal Diameter 18"

Power Handling (RMS)600 Watts (max)1200 Watts

Impedance 8 ohms

Frequency Response 30 to 3,000 Hz

Sensitivity 98 dB 1W/1m (this matches my fullrange very closely)

Voice Coil Diameter 4"

Thiele-Small Parameters

Resonant Frequency (Fs)35 Hz

DC Resistance (Re)2.5 ohms

Voice Coil Inductance (Le)0.86 mH

Mechanical Q (Qms)5.7

Electromagnetic Q (Qes)0.43

Total Q (Qts)0.4

Compliance Equivalent Volume (Vas)11 ft.³

Maximum Linear Excursion (Xmax)7.6 mm

Surface Area of Cone (Sd)1241.29 cm²


As most know here I'm very naïve about driver specs and how they're used to help decide what type enclosure it's best suited for. So I really need your help here. Plus I have these two 18" 2241H drivers sitting around and really want to put them to use, rather than purchasing another set of drivers. I look forward to the input I receive from those who choose to help me...
