Boston Acoustics RX87 5x7 iCar Speaker

Price Paid:  $600.00 from Tweeter

Year / Model Reviewed:
2003 SL 80 (5x7)

Strengths:
Crystal clear highs and lows that make perfect harmony with one another. This makes an impressive system, even without any subs.

Weaknesses:
They were expensive, but I've learned the hard way that your system sounds as good as the money you spend on it.

Summary:
These are the new, high-end coaxials for Boston. They sound so loud and clear that I don't think any sub could ever drown them out. I have 4 of them running off of an eclipse 8443 head unit, and a 300/4 JL amp. The fact that I am running the speakers with some of the best equipment helps but I have never heard any coaxial sound so good. These speakers have dual stage aluminum heat sinks, massive neodymium motor structure, kortec tweeters, integrated system specific multi-element crossovers (Gives you the benefits of component systems in a coaxial), copolymer cone, contoured tweeter plane, ferrofluid cooled voice coil, AMD woofer management system, and a nasty warranty. It doesn't get any better than that. If any one else has these speakers please write a review, no websites have this model listed yet.

I have heard many products from Kenwood , Eclipse, Alpine, JL Audio... Yet nothing comes close to the SL 80's

Strengths:
None

Weaknesses:
None

Summary:
Very nice sounding speakers. With Boston Acoustic's vauge power ratings its hard to know just how much RMS you can send to their speakers, but i was using 65 RMS without a problem. I'm pretty sure you can go higher and be fine. Boston Acoustics makes a fine speaker, I would reccomend it.

Price Paid:  $150.00

Strengths:
Perfect balance, very clear, great across the sound spectrum

Weaknesses:
None

Summary:
The very best 5x7's I've ever heard. The price is amazing for the quality, and they sound much better than other brands trying to bite them off. While others complain about sound quality, they really should check into an amp... at high volumes, a cheap amp will distort way before these speakers. I heard these on an Alpine amplifier and haven't heard clearer speakers anywhere. My friend is running these at 50 watts RMS off of his Eclpise head unit and can't be touched. I'm powering them with the Alpine F-307 with the same power and blow him out of the water.
These speakers are a great value, and I recomend them to anyone, whether they are upgrading from factory or want to compete. Boston Acoustics has perfected the art of building speakers.
The balance is perfect, and the clarity is beyond any speaker I've heard in my lifetime

Similar Products Used:
Infinity--not enough bass, cones cracked under high bass usage (but little power)
Pioneer--since the bostons have a higher Signal to noise ratio, there isnt any static like there is on the Pioneer

Year / Model Reviewed:
 not sure

Strengths:
Great highs
great mids
loud
do not distort very easily
handle power quite well

Weaknesses:
nothing really

Summary:
Overall I highly recomend these. I have them in my truck and they are loud. I cannot get a sub to drown them out and I do not have an amp for them. Just the deck. I love these speakers. I paid 140 for them and they sound excellent. They are all a average car audio person needs for good mids and highs without buying components.

Infinity kappa 5x7. These are cleaner and have better bass for speakers

better than polk and infinity in it's 5x7/6x8 competition.
