Anarchy 554 or 558 depending on whether his amp can handle 4 ohms.

Cheap but sounds good:

Or TCP series, but on backorder currently

You could also try a mark audio full range driver I guess , though coming from a Logitech, he may be used to a "warm" sound with lots of bass

Full measurements for the AlTi DIY 2-way Bookshelf Speaker Design Link to the AlTi Design Thread The following measurements were performed on my 10' tall outdoor turntable, measurements taken at 2.83v / 2M on the tweeter axis and scaled 6dB for approximate 1w/1m level. Measurements gated at 14ms

MTG Designs AlTi DIY uses a combination of a HiVi M5N 5.25 inch woofer and a Dayton DC25T-8 tweeter. Very economic and worth a look.

The Tang Band W4-1720 and W5-1685 are on the higher end of the price spectrum, but play very cleanly well into the midrange as well as very low into the bass range. They get a bit stressed below 80hz, but at moderate volumes can really rock the house deeper than you'd expect. Having such a broad range can really allow a variety of crossover arrangements, and the distortion is great above 100hz. I haven't heard the 5" version but I imagine it's less stressed at similar volumes, though it supposedly has less upper range. Having such a broad extension should also make crossovers easier, as it will behave linearly until 8-10khz. The magnets are no joke, either. It exerts a lot of electrical control over these small woofers, and generally plays at a low sensitivity. Mine cover most of the vocal range, crossing at 3.3khz, and I only notice IMD when the port chuffs. It's nice not having voices split between two drivers, and it feels a lot like I have a dedicated midrange that can play adequate bass in the nearfield at the same time. It's also informing my current preference to have the "telephony" range (300-3000khz) covered by a single driver without phase flipping or directivity interference.
