This seems a logical response. Occupying a niche market comprising the most discerning audio enthusiasts and having committed itself to detail, regarding both the choice of components and materials as well as the design and manufacturing processes, very little had distinguished PHI from being a fully customised loudspeaker manufacturing establishment. The main existing lines of loudspeaker models such as the downPHI^® , the phISH and the Siderium would be continued, with minor modifications, and current production would be conceived around these broad concepts.

So what are these? Broadly, these are three kinds of loudspeakers: the Voigt pipe (TQWT), the intensated short horn (ISH) and the double taper tuned pipe (DTTP); all three employ single driver reproduction (in some cases enhanced by support drivers at the frequency extremes) and bi-pole or our new π-pole architecture.

The ISH is a Voigt pipe, but with substantial mass-loading, making the loudspeakers smaller in order to enable them to fit in the average modern home.

The DTTP consists two back to back Voigt pipes, joined at their bases, enabling very low frequency reproduction.

SO HOW DOES ONE GO ABOUT ORDERING?
 

The order process is simple:

• Contact PHI by email
• Specify your needs in terms of size/cost/application and/or which of our models seem appropriate
• Specify drivers you might be interested in (or already possess) and your materials of choice
• PHI shall respond with suggestions and a quotation
• When the quotation is accepted, a 50% deposit is made to cover immediate costs
• PHI shall indicate the time required for development and manufacture
• Production commences, with frequent updates sent to the client
• Delivery

PHI has, for the almost five years it has been in operation, continued to impress just about every person who has had the opportunity to audition our products, many claiming that these are the loudspeakers they have had to compare any loudspeakers they've since encountered with. We are confident of continuing, if not improving upon, this tradition.
