Atlantic Technology 4400 THX Home Theater Speaker System


Atlantic Technology has introduced the System 4400 THX Select home theater speaker series, replacing its critically acclaimed System 4200e system. The new series maintains the same driver complement and electronics as its predecessor, with improved aesthetics and ergonomics for custom installation.

“The System 4200e’s performance was so universally adored by critics, dealers, and consumers alike that we decided to do something radical for its replacement,” comments Atlantic Technology President Peter Tribeman, “we didn’t change a single acoustical component or parameter. There were, however, some changes and improvements that had been requested — including a simplified wall mount system, and a cosmetic update to match the larger THX floorstanding systems. We’re glad to be able to accommodate those requests while still maintaining the essential character that’s made this such a successful product line for Atlantic.” In response to requests from dealers, installers, and consumers the System 4400 LR and 4400 C speakers now feature inset speaker terminal cups, and the 4200 LR speakers include integrated keyhole mounting slots to allow for simple flush mounting on the wall. Additional changes to the series include an updated tweeter mounting baffle to match Atlantic’s other THX speaker lines, and a new satin black finish for the 4400 SR surround speakers.

The Atlantic Technology System 4400 provides the home theater enthusiast with premium THX Select certified performance in a moderately priced product that looks and sounds like a far more expensive system. The 4400 LR and 4400 C front speakers each use a pair of 5.25-inch GLH (Graphite Loaded Homopolymer) woofers mounted flanking a single 1-inch silk dome tweeter. The 4400 LR employs a vertical MTM configuration for wide, highly linear horizontal dispersion, while limiting vertical dispersion to reduce unwanted reflections from the floor or ceiling. The 4400 C includes the same drivers oriented horizontally, but with the woofers side-by-side and the tweeter above and between the woofers.

Both the 4400 LR and 4400 C include a pair of controls that can adapt sound quality for different speaker placements. A three-position High Frequency Energy switch adjusts for rooms that are acoustically too bright or too dull. A Boundary Compensation toggle can be used to adjust the lower-midrange output to compensate for the sound colorations caused by placing a speaker close to a TV screen, or building it into a cabinet or shelving unit.

The 4400 SR dipole/bipole surround speakers use two oppositional woofer and tweeter systems, angled to the left, and another identical system angled to the right. A front-panel switch allows the pair to operate either out of phase in a dipole mode typical of side surrounds, or in-phase as a bipole speaker for rear surround use.

The Atlantic Technology System 4400 speakers will be available in late May in attractive satin black finishes, with the 400 LR and 4400 C also available in gloss black. Suggested retail price for the 4400 LR is $1,050 per pair; suggested retail price for the 4400 C is $600 each; suggested retail price for the 4400 SR is $950 per pair. Ideally, the system would be combined with an Atlantic Technology 642e SB subwoofer for a 5.1-channel system price of $3,800.
