Smooth action

Speakers are great no problem one had a small imperfection but didn’t affect the sound. So far so good.

I had a blown mid-range speaker in my Infinity home speakers. Not only does it sound good but it was a perfect fit. Even the screw holes lined up. Great speaker and price.

TCP115-8 is a "drop in" replacement for the Altic Lansing 5100 5.1 Speaker System. In fact, these seem to produce better sound than the original OEM 4" drivers. The OEM drivers had foam surround, which decompose over time. The new drivers have a rubber surround which seemly will have a longer life. Screw holes align exactly, only need to solder speaker leads. Speakers also include a foam sealing gasket. If you have an AL 5100 system, these new drivers will make your setup sound better than new.

Good sounding speakers. Arrived on time and well packaged. Not much of a flange for the screws so the hole has to be PERFECT, or the speaker will fall through!

We hated the idea of getting rid of our sound system. Although not bluetooth, the sound has always been spot on. These replacement speakers arrived quickly and are perfect.

Great quality, and affordable for my mid range in my bookshelf speakers

This subwoofer is made from very high quality material. The bass is tight and very accurate. I'm very satisfied with this.

Using the sub in a 0.75 cf sealed box to add foundation to my French stand mounted speakers. Love my speakers, but they need help in the low bass, and this sub seems ideal. Had been using the cheaper dayton 8" in a slightly smaller box, and it is an excellent woofer, but this sub extends lower in freq. and has more output down there. Matching a sub to quality speakers can be frustrating, and this is the 5th or 6th sub have used with the Triangle Comete speakers. Problem has been finding a sub quick enought to blend with the Triangles, which are Very fast. Both this driver and the cheaper dual v.c. 8" are able to match the speed of the speakers, but this HF4 provides more solid foundation under the Cometes......very satisfied with this high quality product.
