I don't see any weakness in this.

every thing

none

these are great really clean. not much mid bass but its not needed if you have a sub i have a phoenix gold amp running it i bought the 3 yr repair on it i thought they will blow by then because of my past speakers(nakamichi focal and etc) i mess alot of speakers up there is a lil wear after 3 yrs but still going strong. the focal had alot of mid bass but it was fragile

- crisp - clean - goes down smooth with no after taste :)

- None that I have found

I have never run good quality components before. I previously had two sets of Infinity Reference Components and the Boston RC620's make the Infinities sound like the speakers on my grandma's record player. Everything is so clean and crisp it is amazing. It truely does bring music to a whole other level. Nothing but comments from friends about how amazing they sound. A little story about the $200.00CDN - a guy bought them 3 months ago - bought a new vehicle and they didn't fit anymore. Talk about a lucky score on my part.

Superlative tweeter and astoundingly accurate mid-range. Adjustable tweeter levels in the crossover to tweak the tweeter's output to your own taste. Soft dome tweeter to reproduce clear, crisp highs without the shrill sound of most metallic tweeters.

There are none...I tried to find them, honest.

Before these speakers I had a pair of ADS AL-6 separates for about the last 6 years. Those speakers were as good as any speaker I have ever purchased but they have now been surpassed by the Boston Acoustics RC-620's. I have tried to find any weakness in these speakers and just can't do it. The tweeters are magnificent. Many car speakers have a tendency to be overly bright and shrill...not these babies. But don't be misled, these speakers reproduce crips, clear and clean high frequencies. They also shine in an area that is lacking in a majority of car speakers...the mid-range driver. These speakers re-create the mid-range frequencies in a way that will make you sit up and take notice. Human vocals are reproduced accurately without a hint of chestiness or coloration. Listening to Jackson Browne's "Saturate Before Using" which was recorded in the early 70's showed me just how true these speakers are to the male vocal range. Astounding is the only word that comes to mind. Again, don't be misled, these speakers can also headbang with the best as I discovered when listening to Linkin Park's latest release "Meteora". I have yet to listen to my entire genre of music but I have no doubt these speakers will shine no matter what the source may be. These speakers are probably the equal of most speakers selling for twice the price. At under 300.00/pair I doubt there is much on the market that can touch them. If you are looking for high end sound for a more than reasonable price, look no furthur than the Boston Acoustics RC-620.

- Fit in the stock speaker and tweeter spaces. - Excellent sound quality at a price I can live with over the life of the car.

Probably need a little more power than a head unit can provide and the reason I bought the amp.

Have these components installed in a new 2003 Miata powered by an Alpine's 7893 head unit (4 X 60W peak - 4 X 27W continuous). I read many reviews about low sound levels and lack of bass in the Miata stock system, but the rally components address both issues perfectly. The highs are crisp and the bass is just what I want... I'm not interested in the boom boom punkish bass you hear rattling your house late at night, but I still like the levels being put out. There's not too much space to fill in the Miata's cabin so there's really no need for additional speakers. I've just purchased an Alpine 50W X 2 amp and this should increase the RC620's sound quality just that little bit higher.

The midrange power of the speakers is great. I am able to play a large range of musical types at quite high volumes and still without distortion as my MTX 6000's did so easily. I love the tweeters on these speakers and finally am happy to find a tweeter that is not so razor sharp that i lose definition from my mids.

The loundess of the speakers could use a boost but that is most likely from starving them with my current amp

I was extremely impressed with the sound quality of these speakers. I decided to locate the speakers in the kick panels of my Subaru 2.5RS. The sound quality was wonderful and it enhanced the imaging to sound near center. I am extremely impressed with how much power these speakers can take and I know I am far from feeding them the true power that they do need. The tweeters are bright but not to the point where it will overpower the rest of the system. The midrange bass is absolutely incredible and nothing short of magnificent for the money. For the money i have chosen the rally series of the pro series. I was impressed with the rally series but am considering the upgrade to the Z series of Boston Acoustics!

great mids and highs.

Boston really needs to address the bass issue for such an expensive set of speakers.

I have these speakers hooked up to a two channel US Acoustics(80 watts x 2) USX 2080 amplifier. I have recently added a 10 inch Rockford Fosgate subwoofer which is being independently driven by another bridged two channel amp. i hate to run a bi-amp configuration but i felt it to be necessary to achieve the full sounding music that i had been promised when buying these speakers. As stand alones, i feel they lack quite considerably in the low end department(thus the sub). Now that they are complementing a good sub and not responsible for pounding out the lows, i find them to be a VERY high quality mid and high producing speaker set.

3 posititon adjustable crossover. Tweeter is sharp but not metal sounding (things sound exactly the way they are supposed to). Great midbass (if you power them you may want to look into sound dampening for the doors). Unbelivable front stage (I have tweeters in a pillars and drivers in door).

None

Got these almost 2 years ago (nothing has changed for 2002 same RC620s) and I'm amazed about the extreme clarity. Let me tell you I don't have my amp yet (I used to have them amped a while ago but amp got stolen)and they are running of the HE and can play extremeley loud without distorsion. I only have the components hooked up and the sound feels the car like you are at concert. Front stage and width plus instrument adjustment perfect you can really hear all the instruments and the highs are amazingly crisp, sharp and precise (I really like the speakers he he). Every time I ride in somebody else's car I like the way their car sounds but when I get back to my car I come to my sense because it feels like I'm at a live concert. People are amazed when they hear them that I only have components running and without an amp. Go to your local shop and listen to them, then listen to anything else they have there (MB Quart, JL, Boston Pros which cost a lot more) and find out how amazing they are for the money.
