Campground Goldilocks

Ricky from Chesterfield, VA on 3/12/2024

Installed in a travel trailer RV ceiling, paired with the RF T152 coaxial speakers. Existing sub and speakers were subpar to say the least. Chose the RF M1D2-8 because of weight, price and lower power handling as I didn't want to go extreme inside the camper. I also wanted a sub that would perform without the need for an enclosure. I was planning to run a small external amp, but after connecting to the cheap HU with a built in sub channel with 24watts rms, this thing puts out what I was missing. It puts out enough that I need to add some deadening and tighten some stuff up to stop the rattling. Nothing crazy, I just don't want to hear anything rattling. It's amazing how good this sounds on so little wattage. And before some people think that I don't know what enough bass is, I have several car setups with the lowest one hitting 144dB sealed, on the dash, with a TermPro. I've also sat in a truck that hit 168dB on a 30 second average. This isn't close to any of that, but most people at a campground aren't going to want to hear me jam, but if you want to have a few beers and enjoy some good music, this should do it for you.

Pros: Price, weight, efficiency and infinite baffle capability

Squeeze a 10" in!

Stephen from Mcgregor, TX on 3/14/2023

Verified customer

Not a fan of 8" subs and I purchased due to space constraints. Very disappointed with the results and ended up replacing two 8" with a single 10". Not blaming the speaker but it just doesn't suit me.

Pros: Size

Cons: Not deep enough sound

Crutchfield response on 3/15/2023

Great compact subwoofer.

Crutchfield customer from Gig Harbor, WA on 8/13/2021

So far this sub has been perfect. My boat had very few places to mount a sub and this worked perfectly. I have not hooked up the LED lighting yet, so I cannot speak to that feature, although it looks pretty straight forward.

Pros: Great for tight spaces.

Cons: None

Got this for my 21 foot bow rider and it thumps like only a Rockford Fosgate does. Nice little 8 inch sub for the price.

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
