Beskrivning
”Designed to excel in previously impossible spaces.” – JL Audio
12″ Baselement, byggd med JL Audios patenterade ”thin-line” teknologi leverar 12TW1 en kraftfull kombination av lågt monteringsdjup och lång slaglängd samtidigt som den är optimal för små utrymmen (18.4L). Tillsammans med en speciell korg i gjuten aluminium gör att den fungerar i extremt trånga utrymmen, t.ex installationer under säten i lastbilar, 2-sitsiga bilar, och en mängd andra kreativa byggen som kräver en kompakt design med låg profil.
TW1 – Optimerad för små lådor, TW1 levererar all den rika, djupa och kontrollerade basen som du förväntar dig av en bas från JL Audio.

| Enclosure Notes * The enclosure recommendations listed above are external dimensions which assume the use of 19 mm thick material. If you are using 16 mm thick material, subtract 6.5 mm from each dimension. Do not use any material with a thickness of less than 16 mm as this may compromise the rigidity of the enclosure. * All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account. * When using multiple subwoofers in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support. * We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance. * All specifications are subject to change without notice. |
