IMF RSPM Mk. IV Speakers

Item Description

One pair of IMF Reference Standard Professional Monitors (RSPM) MK IV. How do they sound? Incredible! I have never heard such incredible low frequency bass; not the rubbery, bloated the kind. The RSPMs give you the sensation of feeling the presence of the bass. According to published specs, the RSPM MK IVs' will go down to 17Hz. Imaging is pinpoint with crystal clear highs without that annoying metallic brightness. They sound best with jazz or classical music, and anything acoustic. They are extremely revealing. If you have a vinyl collection, these speakers will reveal all the strengths and weaknesses in the recordings. These Specs are borrowed from the IMF Electronics site:

Why am I selling them? We recently moved and the speakers are simply too large for the space we have.  The fortunate buyer will have to bring someone to help collect them. I don't have the manuals but plenty of information can be found online. The stands, perhaps more rare than the Loudspeakers, are included.

THIS IS A LOCAL PICK-UP ONLY! Shipping these would be a nightmare to contend with. Buyer must pick-up in Waynesville, NC. Disregard Shipping info. Audiogon requires something in these fields. And again, bring some help. Cash or PayPal Upon Pick-up.
