Forte IV Overview

High Performance Is Our Forte

First introduced in 1985, the Forte quickly established itself as the most popular Klipsch model. The elegant design and outstanding performance made Forte a standout among its competitors. In 2017, Klipsch re-introduced the Forte as part of the Heritage speaker series. The new Forte IV features updated cosmetics and the latest advancements in acoustic engineering while maintaining the original charisma that made Forte so popular.

DESIGNED AND MADE IN THE USA
Don’t mess with perfection. We’ve made some important upgrades to the Forte IV,
but it remains relatively unchanged since its inception. Remember great sound?
We do, too. The Forte IV enclosure is still made in the USA, by proud craftsmen in Hope, Arkansas. Just like Paul W. Klipsch (PWK) intended.

HIGH-EFFICIENCY, HIGH-PERFORMANCE LOUDSPEAKER
The Forte IV hosts a three-way design utilizing a 12” woofer and horn-loaded midrange and tweeter. The Forte IV incorporates an all new K-702 midrange compression driver, featuring a polyimide diaphragm for exceptional detail and dynamics. The K-702 midrange is mated to a modified Tractrix® horn — featuring our patented Mumps technology for even polar response of mid frequencies, giving you more consistent sound throughout the listening area. The titanium diaphragm high-frequency driver has an all-new wide dispersion phase plug for providing exceptionally even high-frequency dispersion for a wider, more accurate sweet spot.

PASSIVE RADIATOR YIELDS FULL RANGE PERFORMANCE
The Forte IV’s well-extended bass is found in the use of a rear-mounted passive radiator. A mammoth 15” (38 cm) in size, this sub-bass radiator operates on acoustic pressure generated by the active woofer for greater bass output and extension.

NETWORK
The Forte IV has been completely revoiced from its predecessor, utilizing premium
componentry in an all-new high-fidelity network — minimizing electrical degradation throughout the circuitry — for truer-to-life sound with best-in-class efficiency and power handling. The new network draws from the classic three-way steep slope design of the legendary Klipschorn and La Scala speakers.

BI-AMP INPUT PANEL AND BINDING POSTS
Forte’s premium, aluminum input panel accommodates large, high-quality speaker cables. Strong, versatile and quality binding posts provide the capability for bi-wiring or bi-amping.

BOOK-MATCHED WOOD VENEER
Klipsch only uses book-matched wood veneers for the Heritage series. The veneer
leaves are kept in order as they are delicately sliced from the timber and precisely arranged to provide a mirror image at the splice joint — like turning the pages of a book. This gives each speaker an aesthetically appealing and consistent appearance that is treasured more than any other cut of wood veneer.

MATCHED PAIRS
Every pair of Heritage series loudspeakers are grain-matched using wood veneer
panels that come from the same timber. Each cabinet is carefully matched so that each speaker in the pair is practically indistinguishable from the other. The speakers move seamlessly together through the factory, and each finished product is inspected and labeled with sequential serial numbers, ensuring that your Heritage series speakers leave the factory as a meticulously crafted set.

BUILT TO LAST
While each and every component of the Forte IV is built to last, Klipsch has always recognized the unique and critical role of a loudspeaker’s cabinet in the sound reproduction process. From the craftsmen in Hope, AR to the engineers in Indianapolis, IN, Klipsch has always put an extraordinary emphasis on cabinet design. The Forte enclosure is assembled using only the highest-grade adhesives and fasteners. This is a speaker you will hand down from generation to generation.

I/50 Intergrated Amplifier Overview

The I/50 Integrated Amplifier is the first product in an all-new series from Audio Research. Functionally simple, visually engaging, and musically sublime – the I/50 takes music listening to a whole new experience. Hand-crafted in Minnesota, the I/50 is built with the same attention to detail as all other Audio Research products – each one even gets its own listening test with sonic designer, Warren Gehl. Available in six colors, the I/50 features Cerakote finishes for a beautiful and long-lasting look. The modular design allows for the installation of two audio modules – a Phono Stage, and a D/A Converter (to come in 2022). The high current, 50 watt per channel amplifier is capable of driving a wide variety of speakers. A headphone jack allows for personal listening time.

The I/50 is designed to be easy to use, and has three controls on its top panel – Power, Input, and Volume. Two LexieTubes® provide display information for input selection and volume. Two matched pairs of 6550WE vacuum tubes, along with three 6922 tubes, stand in front of the perforated transformer cover. Three single-ended inputs and one XLR input provide connectivity for most systems, along with 4- and 8- Ohm speaker taps to accommodate your speaker of choice. One input can be assigned for pass-through function. A full-function metal remote control provides further functionality and operation. An optional tube cage will be available.

As with all Audio Research products, the I/50 is built entirely in our Minnesota facility by a team of skilled technicians and expert craftspeople. Offered in six colors, the I/50 is the first product completely finished in-house. The Audio Research finishing lab encompasses a purpose-built painting facility and laser imaging and marking machines to produce a luxurious finish normally found only on much more expensive products. The Cerakote finish is not only beautiful, but designed to be enduring and easy to maintain.

The performance of the I/50 belies its compact design. 50 watts of all-vacuum tube power energize your speakers with beautiful and lifelike music. Designed by the Audio Research engineering team and fine-tuned by Warren Gehl, the I/50 has been given the same level of care and attention as our Reference Series products. The ability of the I/50 to reconstruct a musical experience will thrill and excite all who hear it. Thanks to the substantial power supply and high current design, the I/50 provides controlled and dynamic playback – even on challenging speakers. The Phono module provides 42 dB of gain, allowing a wide choice of moving magnet and high-output moving coil cartridges. The D/A Converter will have multiple connection options and an array of decoding formats to accommodate the wide spectrum of music formats and resolutions. The I/50 is a truly integrated product while providing renowned Audio Research performance and sound quality.

RS250A Complete HiFi Network Streamer Overview

The new RS250A features an upgraded DAC, opamps and word clock. The chassis gets an upgrade too, as it is now available in silver or black. With a large touchsreen display, terrific user interface, and the ability to operate the RS250A with a remote one can fully configure and operate this network music streamer without a tablet or phone.

Last there is the option to use the RS250 as as a streamer only, keeping one's existing preamp and DAC in the system.

The Streamer
The streamer can connect via Ethernet or Wi-fi. It has a powerful Hexa Core CPU with an Android based operating system. This also means you have compatibility with Android AND iOS devices. One can add up to 4tb of internal storage, connect an external drive via USB, or access your music library on your home network's NAS.

The DAC
The RS250A uses a new DAC and clock with proprietary processing that offers a low-noise, low-distortion, ultra-high-resolution sound with rich analog density. Sampling rates go up to PCM 32bit/768KHz and native DSD512 (22.5792Mhz). In addition, there are 5 filters one can choose from for tailoring the sound to one's individual preference if using the Ethernet input. The USB input is limited to just one filter however. Additionally, oversampling can be implemented as well if desired.

Linear Power Supply
The RS250A is designed with a low-noise toroidal linear power supply. Something that is difficult to find at this price point.

Flexibility
One thing we found very interesting about the HiFi Rose products is the ability to set the analog output voltage. There is of course the variable setting if one wishes to use as a volume control. But there are several fixed settings one can use to optimize the gain for ones preamplifier or amp.
