Infinity REF1000S Reference 10 Inch Low Profile Subwoofer with SSI (Selectable Smart Impedance)

I had one of these for three years and recently got a new truck with Bose system. I like the sound but no bottom end for the bass notes so I began searching for a new box to go under the back seat. The one I bought was for two shallow tens in a down firing configuration.Knowing how good this sub performed I decided to get another one but didn’t want “new “ as that would mean one already broken in and one stiff one that needed TLC until it loosened up.I fired them both up today with my old Infinity amp and “Boom”!!!This next part is not about this sub but this line of subs. The connection on these is old school. It’s literally just two blades like on 80s speakers. I would think that this being 2024 , that Harman would get with it and use better hardware for their outstanding speakers. I mean I solder speaker connections but not everyone has the skill set or the patience and just prefer simple solutions.This is a wonderful sub for a shallow speaker and puts oomph into everything from hip hop to C&W to heavy metal… i guess I’m saying if you’re looking for a shallow SVC with selectable ohm load don’t hesitate. This is a good’un and definitely not a budget woofer.

I put a set in a down firing position in my suv and they sound great.for the money these are the best value out there. Do not distort at any level.

Amazing subwoofer!! I bought this sub to swap out my Kicker CompC I got that came with a subwoofer box for my Ford F-150. The Kicker had similar specifications being a Single voice coil low profile sub. It actually has a higher RMS rating over the Infinity but can’t even compare. Kicker would start to distort at high volume, where as the Infinity isn’t even phased by it. This Inifinty has a selector switch for use as a 2ohm or 4ohm which is awesome and helps with your Amp hookup. I have all new Infinity Speakers throughout my F-150 ( 6x9 Kappa’s in front and 6.5 Reference series in rear) so I wanted to match the subwoofer. Boy I sure am glad I did! This sub is definitely under rated at 200RMS watts, because I’m able to turn it up higher then I was with the Kicker (which is rated @ 300RMS) and there’s absolutely NO distortion!! Having 800watt Max allows for hard hitting bass. The sound quality is just unparallel just like my Infinity speakers. The slim design also allows for installing in very tight slim boxes like the one I have which is great when needing to be used in a truck cabin application or to save space. I haven’t even broken in the subwoofer and it sounds amazing so I can’t wait to see what it will sound like in a week or so. Infinity makes amazing, true quality products and I’ve always purchased with confidence. Infinity and JBL are a Harmon Kardon company. They make some of the best audio products on the market. JBL has an identical slim design subwoofer that’s basically the same woofer, so either of the two would be a good choice. Don’t hesitate just purchase this subwoofer!! You won’t regret it!

Put this in a low profile box for a Jeep Wrangler, but it would not fit without some adjustments to the box. There is a shrouding around the speaker that will make you modify most boxes (make the hole bigger) to make it fit. Also, the placement of the leads for the + and - are in a terrible spot, meaning that you will have to modify the box even more to make it fit.TL;DR: Good sound, good price, but had to dremmel the box to make it fit.

Great sub. Sounds good in my tundra.

Great option if you want to upgrade the factory set, recently installed on my 2023 Kia Forte and let me tell you, what a difference! Powered with a 100W rms micro kicker amplifier it’s perfect for what I need, awesome performance. Highly recommended

Compré este subwoofer y lo tuve guardado alrededor de casi 1 año porque el vehículo que tenía se daño y ya no tenía donde instalarlo, cuando al fin compré otro vehículo y lo instalo, no les miento solo escuché un par de canciones cuando emperezo a salirme jumó y se daño, pésimo subwoofer me duró menos de 1 hora

This speaker gives my Jeep TJ the additional sound punch it needed. The speaker is low profile so I was a bit skeptical. I could not find an appropriate box for the speaker but the spec sheet included details for three boxes. I chose a sealed box because it takes up less space. I built it according to the specs provided and gave it more power as suggested. It work really well. It has both the low base I was looking for and a dynamic range that also boosts the mid-range sounds that the 4" speakers just didn't have. I ran dedicated power from the battery using 8 gauge wire with a 60 amp fuse to a Kicker 500 watt smart amp. At 2/3 volume it puts out amazing sound. I can give it more volume but it's not necessary even at highway speeds and with a soft top.
