I received an email from a senior media representative I have known for many years, telling me that he represents a new speaker company. The company has launched a series of products, including floor stands, stands, wall hangings, surrounds, central channels, and a series of subwoofers.

From the pictures, these products do look more elegant, well crafted, and ambitious than those of ordinary high fidelity start-ups, but I think I've heard a lot of smart and ambitious things before, such as a comprehensive catalog of home theater-friendly wireless speakers and now common products made in China.

Like other companies, high fidelity always offers poetic compliments and focuses on some physical enhancements that are considered marketable. Of course, prelisten also made marketing claims, but the company also provided data: frequency response diagrams (on-axis and off-axis), impedance, phase, and distortion, as well as spectrum diagrams showing off-axis responses along the vertical and horizontal axes. The work of Floyd Toole provides strong evidence for such measurements. These measurements are usually obtained through the fly peak near-field scanner or similar proprietary systems, but few companies publish such detailed information about their products. I hope persistent's transparency will encourage other companies to provide this information.

Although such transparency could not guarantee the success of the dunk, it grabbed my collar and shouted, "we are serious!" So I asked for a large landing bracket, s7t.

When wireless bluetooth speakers come, I'm glad to have someone help them build a job that is definitely not for one person. Three masked men from fidelity imports, Steve Jain, his son Ethan, and a friend quickly assembled and positioned the s7t, whose surface showed spectacular gloss ebony. Five drives are installed on the solid rectangular cabinet, which at first glance seems to be installed on a carefully carved thick front panel. At the back is a charming polished brass panel with two pairs of huge multi-channel terminals and jumper boards. Below is a perforated rectangular metal grille, which echoes on the side plate; When the s7t is used in its standard bass reflex mode, they act as vents. The 27.5lb steel plate connected to the base supports four adjustable outriggers. Spikes are optional.

Secondly, more importantly for me, prelisten provides detailed technical, test, and measurement data, which is far beyond the common data in the industry.
