Allied Nova 7 (1972)
At 70 pounds, these bookshelf speakers were never meant for shelves. They are big, and they sound warm.
Overview
The Allied Nova 7 isn't subtle. It was introduced in 1972 under the Allied Radio Shack banner, as a speaker for the serious hobbyist building a first high-fidelity system. Radio Shack had just acquired Allied Radio, and the Nova 7 was part of a new wave of house-branded audio gear aimed at delivering performance without the boutique price tag. The 1972 Stereo Directory calls it a "bookshelf" model, but it stands 30 5/8" high and weighs 70 pounds. That makes the label more hopeful than practical. These are floor-standing speakers in all but name. The enclosure is sealed and built like a tank, designed for tight bass response from the 10" woofer.
Owners report a warm sound, with one noting the speakers "have a little warmer sound." The sealed cabinet and the oiled walnut finish on the substantial cabinet likely add to that. The design is a 2-way configuration, though the reports conflict. The 1972 Stereo Directory and WorldRadioHistory list it as a 2-way system, while another source describes it as a "3-way 10” design." The manufacturer catalog carries the most authority, so 2-way is the most reliable answer. The front is dominated by a distinctive lattice grille, confirmed across multiple user accounts.
The Nova 7 presents a 4-ohm nominal load, reportedly shared with the Realistic NOVA-7 variant (model 40-5021). That makes it less forgiving with amplifiers not designed for lower impedance loads. It's rated for 60 watts RMS maximum input power, a modest figure by today's standards but in line with mid-tier receivers of the early 1970s. The community adds one caution. It isn't explicitly documented for the Allied model, but the Nova 7B's tweeter is noted to have very low power handling. That suggests care with amplifier matching and volume spikes.

Historical Context
The Allied Nova 7 emerged in 1972 as part of Radio Shack's strategy to rebrand and expand Allied Radio's product line following the acquisition. It was sold through Radio Shack stores and positioned as a premium speaker in a growing family that included the Nova 8 and the larger Nova 9, which featured a 15" woofer. The Nova series was an effort to offer performance-oriented audio equipment to a broader market, bridging the gap between mass-market consoles and high-end audiophile gear. The Nova-7 was also sold under the Realistic brand, with the model number 40-5021, and is reported to be identical to the Optimus-1 except for the lattice grille.
