better than the Sp-23  Time owned: more than 12 months
i have been using this speaker for around 3yrs.I actually had this speaker before i bought the sp-23 and hence the 5 rating.This unit has the speaker that the sp-23 should have had,I use this speaker more than the sp-23 and the only thing missing is the filters like its more expensive brother.If i had my way again id have bought this speaker for my proiii and saved myself a couple of bucks.

quick fix makes it better  Time owned: more than 12 months
I got one to match my 756. It sounded bad. I opened it up and, like someone else mentioned, found a nice speaker in a very small enclosure, and a lot of open space. I drilled several holes in the inner plastic enclosure to vent the speaker into the metal box. What a difference! The speaker has much more bass, and sounds great in all applications.

Nice speaker  Time owned: 0 to 3 months
I like the sound. I have my radio mounted under a shelf so this works out great for me. All in all it sounds good and matches radio nice. Bought mine on an online auction. Don't think these are sold as new anymore replaced with the SP-23. I'm happy with mine.

No problems  Time owned: more than 12 months
I have two of these speakers, Sound Great. They have a hollow sound, but this seems to improve ledgabilty for me? Maybe not a good choice for "Audio" types. I just want to understand what I am hearing. A this speaker does that well.

Bad deal  Time owned: 0 to 3 months
I for the most part like Icom products. This however is poor quality. How this got past their Qualty Control department I will never know. I too looked inside . It is a $1.00 speaker in a $99.00 inclosure. Thank goodness I was able to return it and only had to eat the shipping charges.

Good for my R75  Time owned: more than 12 months
I use this speaker on my Icom R75 to monitor HF Aviation. It beats the hell out of the built in speaker. I have not noticed "tinny" my ears, it sounds pretty well balanced for SSB and CW.

Save your money  Time owned: more than 12 months
I originally purchased the SP-21 with my 756PROII and did not like the audio range but it matched the equipment well. I have since replaced the SP-21 with an RCA 40-5024 4" cube speaker. These were sold at Radio Shack for their RCA Surround Sound systems and I bought 3 when RS closed them out last year.
The enclosures are acousticly sealed. In fact I use 3 of them. (2 for my IC-910H and 1 for my IC-756PROII(look up my call on eham and you can see the speakers in use).

Little speaker, a lot of fresh air  Time owned: 6 to 12 months
Undo the speaker casing screws and you'll discover that the actual speaker enclosure only extends a couple of inches behind the speaker grill. The speaker is mounted in a sealed plastic enclosure (front face of which is visible) which is itself mounted in the metal case with glue and screws. The outer case is simply a cosmetic exercise to match depth of the Icom unit for which this speaker was designed. It works, but wouldn't it be nice to use the whole enclosure to better acoustic effect?

Very nice accessory  Time owned: 3 to 6 months
I purchased the Icom SP-21 external speaker for the IC-746PRO transceiver. It is a very nice accessory, looks great and sounds better than the built in speaker.
