The Infinity Reference X line of speakers have been around for many years, and for good reason. They've consistently performed very well, and continue to improve over time. The Infinity 9623ix was among the best performing speakers in our audio quality tests, and can be found on our list of best 6×9 speakers. Although the Reference the series doesn't feature component speakers, it has speakers that fit all the common installation sizes and even several uncommon sizes. They're affordability is what makes these speakers stand out though. When you're looking to balance cost with performance, the REF-6923IX (and the Reference X line in general) are a fantastic choice.
