Speakers to hang on to for LIFE

After a thought I second Joeyboynj... :). Rel B2 is an outstanding sub. Integrates extremely with mains, very versatile, not to mention the bass itself and spatial info it adds to the soundstage.

If you know how to set them up, Altec Lansing Voice of The Theatre A-7's deliver the real thing.For subwoofer action, try JBL Professional Installed Sound ASH Series Maximum Impact cabinets with old JBL 2245-H 18" drivers installed. They are around 32 cubic feet each.The undistorted bass will hurt you, but you will enjoy it because you are an audiophile.

Revel M20s.

If your switching speakers every 6 months your either very wealthy which is cool, Maybe something is wrong with your equipment that your not aware of yet. There maybe something wrong with your acoustics. After you see past the illusions that go along with installing new speakers, the "honeymoon phase" I call it, you see the flaws that where glossed over. But then ask yourself are you listening to music or just to the equipment? Maybe the problem is elsewhere.

But to answer your question, I have owned KLH Model-Nines for 42 yrs.

If everyone hand on the same speaker for life. We would listening music just like the Flintstone on TV.
Speaker is technology and they sound better everyday. Speaker to hand on to for life for me is none.
