In this review, we will be comparing Sandwich 150 and The Sevens, two Bookshelf speakers from Leak and Klipsch. The main difference between these two speakers is that the Klipsch The Sevens is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the Leak Sandwich 150 is a Passive speaker so has to be matched with an amplifier to get any sound from it. Let's have a brief look at the main features
of Leak Sandwich 150 and Klipsch The Sevens first before getting into our more
detailed comparison.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both Sandwich 150 and The Sevens have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
