Boston Acoustics S45

Amazing

These were the best sounding 4" speakers I've ever heard. I've tried out all sorts of 4" speakers in my car and hands down, the best. I could no longer keep them installed due to the depth being over 2".

Great product from a true Audiophile brand

Unlike many of the brands producing car speakers these days (i.e. "Boss" and others), Boston Acoustics is a trusted and excellent manufacturer of all types of audio products; their name and quality will be familiar with anyone in the professional audio or production industry. These speakers, despite their small size, produce faithful sound across the full range. They are excellent rear or tower speakers for SUVs and vans (4" speakers are rare in smaller cars) and compliment fill-range front speakers (3- or 4-ways, or component systems with tweeter/woofer combos. They also have remarkably high attenuation (called sensitivity), meaning that they produce more volume than usual at any given power level; this results in better low-volume performance as well as higher volume potential. Although their rated wattage is fairly low (they are small speakers), this sensitivity makes up for it, and then some. Physically, they have a fairly shallow (for 4-inchers) basket size, meaning they should fit in any vehicle with 4" stocks...these are maybe 5mm longer than my stocks, and fit easily in their positions. Highly recommended, especially for 40 bucks.

Good Quality

I installed these in a 1983 Mercedes 380SL. The speakers have a low enough profile that the OEM grills for the car will fit over them after install. This an issue on the 70-80's Mercedes SL series. Using only these 2 speakers (as the car has to be modified to add more) the sound is good considering. All in all they are good speakers for the price and the form factor is a big plus...

Great Sound

These speakers are great for anyone who needs to put a lot of sound with a little room. The tweeters on these speakers is awesome, and it is a great set of speakers for their price, boston company for speakers, and at this price, how can you go wrong?

the best

i love theses Speakers. i bought 6 of them for my 1990 jag xj6. these speakers are tight and punchy, and very clear . the bass is nice too.

good product

I have these in my dash and would recommend putting them in enclosures to get the full effect of these. great speakers though, they handle the head unit's 20 watts RMS no problem. I will be adding an amp for these soon, as well as an additional set of 6x8 speakers run by the same amp to fill out the sound.
I recommend these speakers..

Impressive Sound!

These little 4" speakers surprised me with how loud they are. I originally had an old pair of Kenwood eXcelon 4 inchers installed in the dash of my '92 Mercedes 190E but after filling the rest of the car with Boston Acoustics (SX50s, SL60s, SX55s, and 2 8" Rally Series Subs) I figured I might as well finish off with these. They dropped right in to the factory holes, and the tweeters were low enough that the factory covers easily fit over them. They were so much louder than the Kenwoods that I had to readjust the balance on my head unit to get the sound centered again. Great quality, for a great price!! Highly recommended!

Great Speakers

I purchased these speakers to replace the OEM speakers. I am very pleased with the quality and sound from the Boston Acoustics 45 speakers. They were easy to install.

Great Small Speakers

If you don't have much room for speakers these are the ones to choose. They complete my 7 speaker system quite nicely (Components, 6X9s, 10 inch sub, and these 4s). Good quality, look nice, and inexpensive.

Good speaker for the price.

I would have to say Boston Acoustics is up there in the audio community. They have been around for a good amount of time, and any true audiophile knows BA. These little 4" speakers from boston produce some GREAT sound. For $60.00 you cannot go wrong. The quality of the speakers and design is grade A top notch. Buyers, if you buy this product I guarantee you will be happy with it.
