It should be pointed out that smaller speakers that are also higher efficiency will tend to have more limited bass extension. That’s just physics and the way it works, including Tekton. So a separate sub will likely be needed to get full or near full range bass. You need larger speakers in general to get full extended bass AND high efficiency.
So just pointing out that high efficiency speakers are not a panacea and like most things have a down side. One can choose to live with or work with that or not......its all good.
Also integrated amp technology has come a long way in recent years. Much more can be accomplished in tight quarters there than in years past. Good modern integrated amps can deliver a lot of power and current and a lot of features with a very very low noise floor, unlike much vintage gear of the past. The Vanatoo products are a good example.
