Our take on the Boston Acoustics S35

Boston Acoustic's S series speakers let you enjoy clear, natural sound, even with a low-powered system. And with a wide variety of sizes, you'll find a set for most commonly-sized speaker openings.

The Boston S35 3-1/2" speaker features a 3/4" tweeter with a built-in cooling system for long term reliability and excellent power handling. A contoured tweeter plane guides high-frequency output to create a larger listening "sweet spot," while Boston's Amplitude Modification Device (AMD™) reduces harshness in the upper mids for clear, detailed sound.

The sturdy woofer cone teams up with a durable butyl rubber surround to produce tight, clean upper bass with minimal distortion. And you'll hear a smooth blend between the woofer and tweeter, thanks to the built-in crossover.

Highlights:

  • 2-way 3-1/2" speakers (pair)
  • copolymer woofer cone with rubber surround
  • 3/4" Type-S3 soft dome tweeter
  • power range: 2-30 watts RMS (60 watts peak power)
  • frequency response: 100-20,000 Hz
  • sensitivity: 92 dB
  • top-mount depth: 1-11/16"
  • warranty: 2 years
  • Our 60-day money-back guarantee

Tweeter: The type-S3 3⁄4-inch tweeter's soft dome is Ferro fluid cooled for excellent power handling and reliability. The AMD (Amplitude Modification Device) located on the tweeter plane provides acoustical tuning for the midrange response while the shape of the tweeter plane improves off-axis response.

Woofer: The copolymer woofer cone with durable butyl rubber surround stands up to the harsh automotive environment.

Crossover: Each speaker in Boston's S line features a specifically tuned crossover to deliver the best transition between the woofer and tweeter.

I have a 2008 Dodge Ram 1500 with the 7 speaker Infinity system. I bought these for the dash. It took me 15 minutes to install both front speakers. The Crutchfield installation master sheet made the install very easy and quick. As far as sound goes, they made my highs sound crisp and clear. I can hear sounds in soungs I didn't know were there. All this with the stock head unit and system. I highly reccomend these speakers for the price and performance. My advisor Paul reccomended these and they didn't dissapoint. Thanks Crutchfield!!

They Fit in Saabs!

Written By Keith, New York on Monday, September 01, 2008
Crutchfield Customer Review (What's this?)
Crutchfield Customer Review

I installed these in my Saab 900SE dashboard about a week ago and I love them. They fit under the speaker grilles and don't touch.

These are my second Boston Acoustics. I put 4" ones in the dashboard of my old Saab and they sounded so good that when I bought a newer Saab I bought 3.5" ones for this dash . Just like the 4" ones they sound great. Nice and clear sound to fill in the mids that the larger speakers leave out. Highs are nice and not piercing. I put in bass blockers for the 3.5's. I did not have them on the 4's. I don't think they're 100% necessary, but they are a nice $10 insurance policy. They keep the speaker from trying to pound out bass and the sound seems to be a little more clear because of it. I did a side by side comparison with and without the bass blockers and they don't make a huge difference; but for loud volumes (i.e. driving windows down on the highway) they are worth it to protect your speakers I think.

Overall, great speakers by Boston Acoustics. I'm glad I purchased my second pair and I'd go back for a third pair if I needed to. 10 out of 10.

The speakers I chose

The reviewer purchased this item from us, verified by the email address on the order.

 
I gave these speakers 5 stars simply because they sound amazingly. They're in my '81 Chevy Pickup, and they're used as In-Dash speakers. They're powered by the Audiobahn A4004V amp (4x50). The Boston Accoustics' RMS is 30 watts, so I had to turn the gain of the amp down a bit, just to be safe. After reading these reviews, before making my purchase, I decided to buy the bass blockers, and I did. I haven't tested the sound with the bass blockers connected and then not connected, but I have heard them with the bass blockers connected. The vocals are crystal clear at full volume, which is something I wasn't used to. Before hooking these up, I had a pair of JBL 3.5" dash speakers ran from my head unit, and they didn't give off a very clear sound.

The only problem I had with these speakers is that they don't fit under my dashboard very well. I installed them, and I put my dashboard back on, but now there are bulges in the dashboard, above where the 3.5" speakers are. It's a sad story, but I'm going to keep them there, and I hope they don't break because they sound perfectly fine, even with the weight of my dashboard slamming on them.

These are the ticket.

For anyone who's drawn to replace his or her dash speakers with the comparably priced Infinity Reference offering, let it be be known that I just put a month-old pair of them out to the curb. Don't let anything you read about the other sizes in that model sway your opinion on the 3.5s: if you want a good pair of voice speakers, that won't slash through every 's' and pierce your brain with every high hat, get the Bostons. The Ref 3.5s have a harsh little tweeters that open the floodgates on high-pitched sounds; the Bostons, I've just discovered, manage them much more agreeably and clearly.
Pair them with 600hz bass blockers, and you'll be able to crank them nice and loud.

Great replacement for Saab 9-3

Crutchfield Customer Review

Although the fit guide says the BA S35 will not fit, it does! A call to a sales advisor showed that it is supposedly 1/100th of an inch too big. I and many other find this to be incorrect - fits just fine!
And it is a huge upgrade over the stock dash speakers in a 9-3 Saab - even the mid-tweeter Pioneer separates in the upgraded system. Much more clarity and "presence".
Too bad Crutchfield hasn't done any research on the installation for Saab's - you get very generic instructions. I might replace the hatch speakers as well if I can find out how to remove the panel without causing damage!

Purchased to put in the dash of my PT Cruiser. Very pleased with the sound quality and the overall quality of the speakers. Have everything under 100Hz filtered out and these perform beautifully. Excellent, clear highs, and good mid-range. They are a great value for the dollar and worth more. This is a very nice, high quality prodcut.

I bought these speakers for the dash of my 1983 Chevy truck. They fit, but modification to the supplied brackets will be required if you are using a new replacement dash pad. The speakers are thicker than the factory units, which causes interference with the dash pad making it not fit properly. I modified the brackets to make the speakers fit under them instead of on top. Problem solved. My dash pad fit like it was supposed to. The sound out of these little speakers is incredible, much better than I expected. Great buy.
