Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

General:
The McIntosh XR5 is an interesting speaker that doesn't come up for sale very often. They have a rather unique design with a hinged front grill that swings out like a door.

During testing we really enjoyed the way these sounded with every genre of music we tried. 

This particular set of McIntosh XR5's recently had their bass and midrange woofers re-foamed by the legendary experts at Millersound to ensure they are performing as good as they can.

SkyFi Cosmetic Notes:
These speakers have a couple of cosmetic flaws. One of the midrange surrounds sustained a tear during reinstallation and was carefully spot repaired. There are also small blemishes to the top corners of the veneer and a chip on the bottom left of one of the speakers. Overall these issues are pretty minor, and the speakers still present well overall.

SkyFi Technical Notes:
The foam surrounds were professionaly replaced on both of the woofers and midrange drivers.

Testing Process:
Our speaker evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, dented tweeter domes, and cone damage. We also inspect the speaker connection points for loose or broken connectors.

After the initial visual inspection we connect the speakers to a reference amplifier with our preferred test tracks. With the speakers placed with proper distance we listen to each driver to make sure that they are producing the intended frequencies with no signs of distortion or rattle.

During listening tests with test tracks we check for proper stereo imaging and bass response at various listening levels. If there are any audible signs of issues, the speakers are taken to the bench where we perform a frequency sweep to isolate the issue so that it can be resolved by component repair or replacement.

Our subwoofer evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, cone damage, or rubbing voice coils. We also inspect the input connections for damage.

After the initial visual inspection we connect the sub at our bench and perform a sine wave sweep from about 200 Hz down to around 10 Hz. During this sweep we are listening for excessive rattle or other signs of improper function.

If the sweep passes we then increase the input level to evaluate how the woofer performs at high output levels. If the woofer has built-in crossover adjustments or multiple connection options these features are tested at this time.

We complete the subwoofer evaluation by feeding the unit with an audio signal in conjunction with our house music system to see how it responds to low frequency content in real world conditions while paired with a full range system.
