skippy124 Posted February 1, 2018 Posted February 1, 2018 Item: JBL 4406 COMPACT STUDIO MONITOR SPEAKERS Location: SYDNEY Price: $150 OBO Item Condition: Fully operational, average cosmetic condition - see photos Reason for selling: Surplus to needs Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: Up for sale are a pair of JBL Compact Studio Monitors. They are fully operational, and sound great!! They have been well used, and have some cosmetic blemishes - see photos. There are some grill pegs broken, a tear in one grill (they look pretty good with the grills removed), hanging brackets have been added to the rear, and there are scratches, marks etc on the cabinets. Some information on the drivers and crossover network employed in these speakers - They feature Pure Titanium Dome Tweeters - Pure Titanium was first used by JBL in the design of diaphragms for high frequency compression drivers. These feature a 25 mm titanium dome radiator which is capable of 30 watts power handling and can reproduce the frequency range from 3 kHz to 27 kHz. The unique “diamond surround” and ribbed dome structure of the model 035Ti HF unit provide control over secondary resonances, yielding absolutely flat axial response to the normal upper limits of today’s recording media. With a basic sensitivity of 92 dB, one watt at one meter, the 035Ti transducer exhibits virtually no dynamic compression. The 162 mm (6.5 in) diameter Low Frequency driver has a filled polypropylene cone which combines the smooth response associated with polypropylene with the resistance to breakup associated with pulp or laminated materials. Linearity of the LF driver is the result of careful attention to mechanical suspensions as well as Symmetrical Field Geometry (SFG). SFG reduces harmonic distortion by producing identical magnetic flux fields on each side of the magnetic gap. This ensures that the voice coil will intersect equal flux lines for both positive and negative excursions of the cone. A flux stabilizing ring placed around the pole piece reduces the effects of magnetic flux field modulation. Overall, SFG reduces distortion to about one-tenth the value found in conventional magnetic structures. A cast aluminum frame ensures mechanical integrity under the most demanding operating conditions. The complex crossover network design produces a seamless system frequency response through the critical crossover region around 3 kHz. The roll off slopes are precisely determined to result in smooth axial and power response. High quality polypropylene and polystyrene capacitors are utilized as “bypass capacitors” in parallel with the larger network mylar capacitors. This design procedure linearizes energy storage in the larger capacitors, and the result is greater accuracy in the reproduction of transient signals. A front baffle control allows precise adjustment of the HF transducer level, enabling the system to be adjusted to taste, or to match a given acoustical environment. Pick up only at this stage.

Sam Z Posted February 2, 2018 Posted February 2, 2018 I could do with 1 or 2 of these tweeters if anyone needs the woofers/crossovers/cabs. But they’re probably too good to part out.
Tasebass Posted February 3, 2018 Posted February 3, 2018 Had a pair of 18Ti's..( commercial version of these) back in the day. IMO these have one of the best tweeters ever made.... Bargain these..GLWTS Tase
kelossus Posted February 4, 2018 Posted February 4, 2018 The tweeter in the 18TI's is not the same as the 4406's. The L20T are the domestic version of the 4406. The 18TI tweeters are worth around $500 for a pair. At the time they were the most expensive Tweeter JBL had manufactured.
