Just upgraded my speakers - do I still need the subs

I will try and save you some pain from all the polarized post.  Listen to your system with and without the subs.  Make sure they are tuned for your speakers (Placement and cutoff).  If it sounds better with the subs, then keep them; otherwise remove them.  BTW, I would try another brand, such as REL and JL.  Depending on room size, you may want to run a stereo pair.

The above is exactly what l am saying ….

Read the original post. He is already running a stereo pair.

Suggesting a new expensive angle of buying new subs will just make the OPs final decision even more difficult. It was not what he was originally asking about, which was …”Do l need to keep the subs?”

You ABSOLUTELY need subs. Those with speakers costing 3 X the cost of your speakers have subs - most REL, BTW, understand that irrespective of the speakers one has, none can perform at such a deep level as a great sub and no subs are  as fast as REL- and the importance of subs relates to the entire spectrum. Bass is the very foundation of all octaves from the highest to the lowest, and without a proper sub, you will absolutely suffer degradation in both mid range and high range frequencies.

There is actually a terrific video you can find on YouTube you can search for with a title something like “is this the best hi-fi system of 2026?” It’s an interview of one of the most brilliant and  knowledgeable audiophile consumers in the world featuring 100k  TAD speakers and an array of a six pack of REL reference subs. He will explain to you why you need subs better than I can here

Trust YOUR ears

Whichever sounds convincing to YOU-with/without is "best."

@fritzenheimer  Listen to @tcutter -- Subs have two basic purposes;  (1) Extend low frequency response for speakers (not necessary in your case) and (2) smooth room modes for low frequencies.  The latter is more important and applies even where you have "full range" speakers that might actually go lower than the subs. With just two speakers your room will have bass nulls and spots that are boomy.  Adding subwoofers will smooth these out and make for more consistent bass in the room.  You'll hear the difference when you shut them off.
