Jointly designed by the late industry legend, Saul Marantz (who sold his namesake to the Japanese, so that current product bearing his name bears little or no resemblance to Saul’s greatness) and a young engineer named Jon Dahlquist, the DQ-10 all but stood the industry on its ear (please pardon the pun). http://www.epinions.com/content_4300841092?sb=1

That’s a B&W DM-70, clearly confused by one of a pair of nattily dressed Dahlquist DM-10s that showed up the other day. Don’t laugh………………..

La storia –  John Dalquist era un socio di  Saul Marantz , che venduto il famoso marchio  e fabbrica , si era messo in societa’  con il primo.

Aveva visto  giusto , questo  Dalquist , aveva progettato dei diffusori veramente rivoluzionari , per l’epoca , e 5 vie  continuano ad essere quasi un record anche oggi. Gli altoparlanti  utilizzati , non erano prodotti hi-end ma normalissimi altoparlanti , che inseriti in questa configurazione , davano ottimi risultati.

Tanto per  farvi capire il supre tweeter piezo motorola , all’epoca  costava circa 1000 delle vecchie lire, ma in breve tempo  sparirono tutti dai negozi , acquistati da tutti gli appassionati autocostruttori e si trovarono dopo in commercio soltanto dopo , ad un prezzo maggiorato……

It’s operation is based on patented acoustical techniques which provide very accurate reproduction of source material.

In order to minimize undesirable effects from diffraction, each driver has been separately mounted on the smallest possible baffle, whose dimensions were determined by the frequency range of the passband.

This is directly opposed to the standard practice of mounting the drivers on one relatively large baffle.

The mounting method used in the Phased Array also makes it possible to incorporate time-delay correction through relative front-to-back positioning of each element.

 

Da qualche tempo sono sempre maggiori gli appassionati alla ricerca di diffusori quali Rogers LS3/5a 15ohm, Dahlquist Dq10, Grundig (in gran parte a causa di questo sito…) ed in misura minore di altre casse (B&W DM6, Gale gs401,Snell type A, etc) il cui …………………….

The bass speaker on a Dahlquist DQ10 is mounted in its own speaker cabinet. The driver used is the same one used in the famous “Large Advent” speaker, which really revolutionized high fidelity due to its new (at the time) “acoustic suspension” cabinet where
