Polk Monitor 11's - Local pick-up only

BlueMDPicker

$175 - Peerless tweeters - walnut finish. No boxes.

I picked these up here in the forum about 6 years ago from Terpsfan and have enjoyed them completely (especially with tube gear.) However, we are moving and I have entirely too many speakers.

They are in 8+ condition, all corners and edges straight, grilles and badges intact, drivers/tweeters/radiators in excellent condition. With original manual.

Color is slightly darker than the flash photo indicates.

I can't ship them or hold them. Local pickup in Ellicott City, MD between now and mid-June required.

Thanks for looking.

Are these the one's that say L and R on the back ?
I have some, and may want more...I really like them...

Ugh...I got all excited when your location said Florida....I would've been all over these. Oh well, GL with sale.

If I can't find a good home for them in the Baltimore/Washington area, they'll be in Sarasota by the end of June. Stay tuned--these are some great sounding floor-standing monitors.

I'll second the "Great Sounding Speakers"!!!
I've got a pair in Rosewood I just rebuilt the crossovers on monday.
Great price also. Best of luck

Dang, I wish I had room for them. I have enough trouble hanging on to my RTA11TL's. I'm in Ellicott City also.

Okay, they are marked for each channel on the back and I tried to give a better view of the color.

Anyone interested before they go to the Bay? (south of Tampa Bay, that is )

very nice speakers and a good price. would be nice to be close to snatch them up. good luck with your sale

Are they going to be in FL anytime soon?

Excuse me for being dense but why would a non-SDA speaker need Right/Left labels....and they're not a mirrored pair--either?

The classic Polk sound....these are like Monitor 10's on steroids. They are also quite rare in that they were only made for a very short time. My father bought a new pair (still in mint condition) after attending a party at Matt Polk's house way back when.

I have seen and heard this pair at Mike's house numerous times over the years. They are exactly as described and Mike is top notch, so buy with confidence and own a true piece of Polk history.

Someone correct me if I am wrong, but I believe these are essentially RTA-12s with all the drivers in the box instead of the tweeter being in the HF module on top. They are marked left & right because the two MW drivers do not crossover at the same frequencies. In order for the RTA to function properly, they are supposed to be oriented as indicated by the stickers on back, though there is some deabte as to which way actually sounds better.

If I hadn't pickup up a pair of RTA-12c's a few weeks back, I'd be all over these. The cabinets look to be primo compared to the cabinets on my 12c's.

There have been several discussions over the years as to whether this monitor was a true "RTA". I think the information you offered might explain why Polk named them as such.

Without really taking this FS thread off on a tangent. Real Time Alignment is explained here in this link

http://www.lenardaudio.com/education/06_x-over_4.html

This is why there are called Monitor's and the only true time aligned speaker was the RTA-12. Polk did name the subsequent series RTA11T and RTA8T but they weren't real time aligned. Those were very good examples of what is called a D'Appolito array which is name after Dr. Jospeh D'Appolito a famous speaker designer

D'Appolito
A loudspeaker configuration developed by and named for Joe D'Appolito, in which a high frequency driver, or tweeter, is positioned between two midrange or low frequency drivers that each cover the same frequency range. Depending on the exact implementation the speakers can be positioned with a vertical and/or horizontal orientation. In either case the two midrange drivers serve a couple of purposes: they combine to create a larger effective woofer or midrange driver size, and they also serve to control the dispersion of the tweeter. The tweeter's output is somewhat corralled or contained by the sound coming from the midrange drivers in a similar way to how two parallel surfaces control dispersion.

There are some variations on the design where two same sized woofer/midrange drivers may cover slightly different frequency ranges, however those aren't considered true D'Appolito designs. The D'Appolito design specifies a third order crossover network. �The tweeter is coordinated with the woofer so that at the selected crossover frequency, the drivers all have similar horizontal dispersion. �(This is not easily accomplished because many drivers behave badly at the extremes of their range.) The advantage of doing it all correctly is one of the most seamless blending of drivers possible. �The result is an absence of any sudden change in directivity with frequency. �This may not mean much for monitors where there is a limited listening area, but in a typical room where a large percentage of the sound is reflected by the room, the effect is dramatic

The Monitor 11 is a very nice speaker but is NOT truly time aligned.

Hope this helps and good luck with the sale Mike, nice to see you posting again. I miss your "What are you listening to" selections

Time Alignment
In a multiple driver loudspeaker system, it is important that the time delay inherent in each driver and its associated crossover network be the same to preserve accurate transient (see WFTD archive transient) response. In other words, the high frequencies and low frequencies much reach the listener's ear at the same time. A system which meets this criterion is said to be "time aligned." One way to accomplish this is to place the tweeter further away from the listener than the woofer, and this is done in many speaker systems. Another way is to design the crossover network to add a suitable delay to the high frequency signal before it gets to the driver.

The phrase "time alignment" is also sometimes used in reference to adding delay to one or more microphones in a situation where more than one mic is being used on an instrument, and the mics are at different distances from the instrument. A good example of this is orchestral recording where several mics are employed at various distances to accurately capture the sound of the orchestra in the hall. The microphones closer to the orchestra are sometimes delayed to be more in "time" with microphones placed out in the hall.

I'm local and very interested! Sending PM.

Sold to the man with the (soon to be) big smile on his face

Thanks Ed.

contratulations. You'll love the M11 RTAs. Huge sounding speaker with detail and loads of high quality music.

mdaudioguy

Yeah, baby! This time next week I'll be jammin'!

See you Monday evening, I think. Thank you Mike!

AudioGenics

you will have a blast when you meet BlueMd...

...congratulations on the 11's !
