Dynaudio is a high-end European Speaker and driver manufacturer. I know them best for their awe inspiring Studio monitors. These few links will show you their Monitor lines. Sweetwater, Dynaudio BM 5A Compact (similar to this home version),

Spec Sheet from Dynaudio. System review from The Perfect Vision, that includes the 42C center channel. Review of the LR matching speakers.

I bought these intending to build out a 5.1 system. Reality has raised its head and I realize I have neither time or money (or space) to build out a 5.1 system of Dynaudio speakers. But I still have a deep love of their sound and power. So these are now for sale, on craigslist. I have hooked them up only to ensure their are working properly.

As you can see in the photo above, the bottoms have been scratch by a previous owner, but from the couch, the front of the speakers is still visually appealing.

Nova-15 Bookshelf Speakers

Tweeter: 2.5 inch paper cone/dome
Woofer: 8 inch paper cone
Power rating: 5 - 60 Watts
Frequency: 60 - 20,000 Hz

These are classic Realistic speakers with real Walnut veneer. They will sound better than the average speaker, and loads better than the cheap $200 home-theater-in-a-box speaker systems so popular these days. These were my first set of "real" speakers.

If you are a Jimmy Buffet fan, I will confess that Jimmy sounds excellent on these speakers. I now have much pricier speakers, but for certain types of music these still beat them. Most recently my parents had been using them.

Polk Audio Monitor 4

Below is an image from a Polk Audio sales flier from the late 80's or early 90's (I honestly have forgotten where I got this picture, but I remember having the same flier many years ago.)

The other pictures are of the actual speakers. These are in pretty good condition. One of the grill pins is broken, but with 3 of the 4 functioning the grill stays in place with no problems.

Twenty years ago when these speakers were new they were the best bang for your buck from Polk Audio, using what was mostly the same woofer all across their line, these were about $200 a pair, and considered a bargain when that driver design was used in $1000 Polk Audio speakers.

Frequency Response 50Hz - 20kHz
Nominal Impedance 8 ohms
Recommended Amplifier Power 10 - 100 w/channel
Efficiency 91 dB

Boston Acoustics HD10

These are Boston Acoustics HD10 speakers from around 1992. They retailed for $449 at that time. They have the distinctive tight and controlled bass of Boston speakers from that time period. The clean controlled sound is why I preferred them other speakers from the period.

Dimensions: 24 1/4" X 12 5/8" 9 3/4"
Weigh: 25 lbs
Frequency Response: 40 - 20,000 Hz
Recommended Amplifier Power: 15 - 150 Watts per Ch.
Tweeter: 1" soft dome
Mid/Bass: 6.5" poly
Bass Radiator: 10" poly

These had a hard life with a previous owner, but the damage is purely cosmetic. It could have been repaired more cleanly, but such is life. The 10" surrounds have been repaired/treated with a special latex formula to extend their life past the point where foam rot would have ended it. The mid/bass surrounds were factory treated and are in great shape.

I have gone back to using cream and razors. This electric shaver is around 5 or 6 years old, but hasn't been used in over a year. It has a pop-up beard/mustache clipper on the back side. New blade packs are about $25 and I replaced them about once every 12 to 18 months. Comes with case, charging cord and electric razor.

Boston Acoustics CR65

Boston Acoustics pretty much invented the small moderately priced high quality speaker with the A40 back in the early 80's. They have remained masters at good quality at a moderate price ever since then. The CR65 could be called the 2002-2003 successor to the A40. Unlike the A40, the CR65 woofer have a rubber surround instead of foam, so they won't suffer from foam rot.

These are smooth sounding speakers that sound great with Jazz, pop, classical, etc. They will surprise you with the bass output for their size, and also blend very well with sub-woofers for a home theater set up. I am listening to them as I type this and they are detailed and alive. When I first bought a pair of CR65's I compared them to speakers ranging up to twice their price. The Boston's matched or beat the detail of more expensive speakers. Even when I expected the higher priced speakers to be better based on appearance and reputation.

These are great for Dorm room, office, bed room, or other small to moderately sized rooms. Paired with a T-Amp they worked very well for me as home office speakers.

Used with a sub-woofer they can easily fill a whole 2400+sqft house with sound. The CR65s also make a wonderful introduction to the world of high fidelity sound. I have seen area bars use 3 or 4 pair of these speakers to provide sound, so they can take demanding content and long hours of play.

As I have told may people given the choice of a cheap home-theater-in-a-box system, I'd much prefer a pair of good STEREO speakers. These fit the bill, nicely.

There is a small scratch in the side of one speaker, seen in the middle photo above.

Compact bookshelf speakers with outstanding audio performance
2-way system-specific crossover

Polk Audio RM3000 Satellites

These were one of the first sets of high quality 3 piece Sub Satellites systems made when the sub/sat idea became popular. The speakers had a damaged binding post when I got them, but I repaired that and they work and sound good.

They do NEED a sub-woofer to go with them. They are very well made an weight more that speakers two or three times their size. The dusk cap on one of them is dimpled, but this doesn't effect the sound at all.

Grills for Polk Monitor Model 4

These are not in perfect condition, but they are in fair condition, 8 out 10. There are minor scuffs and nicks and pulls in the grill cloth. They can't been seen from a distance of a few feet, but noticeable from 1 or 2 feet. Frames and Logo's are in great shape. Could apply new cloth if needed. And I might be able to dig some up, or point you to a cheap on-line source.

These are Polk Audio S6 Speakers (specs on Polk Audio site), they are a good pair of speakers from 1990's. Still in great working condition. Like most Polks these are very efficient speakers so they require very little power to get to decent listening levels.

I hate to see them go, but I have more speakers than rooms in my house and need to clean out some storage space. They would sound best on stands that raise them 6 to 12 inches off of the floor.

According to Polk Site, the specs for these are as follows:

 
Tweeter    1" Diameter (2.54cm)      dome tweeter
Midrange   6-1/2" Diameter (16.51cm) driver
Subwoofer  6-1/2" Diameter (16.51cm) sub bass radiator

Overall Frequency Response  30Hz - 25kHz
Lower -3dB Limit            45Hz
Upper -3dB Limit            23kHz
Nominal Impedance   8  ohms  
Efficiency          91 dB

This is a lovely Antique Oak Typewriter Desk. I have had it it for many years, but have moved to a smaller place and no longer have the room for it, or the desire to continue moving it (its heavy and Solid). I have no idea how old it is, but it is not a modern knockoff. It would be great for someone looking for a nice addition to an office furnished with similar antiques.
