Do we really need anything more than 8" woofer and 1" tweeter for medium size room?

Get yourself a pair of these... and... you'll end your search and your questions.  

Very few speakers sound better at less than 10+ times more money.  Truly phenomenal sound, which rivals the best there is.  Not my opinion - the opinion of many, many others who've sold their "high-end" speakers and replaced them with these.

Though, I agree with them.

Would I rather have the top of the line Nola's, or GamuT's - sure... but... not at their lofty prices.  

Only experiencing them will convince you... but, you will be convinced.

Well... you'd have to experience it to understand it.  

Yes - they do sound as good as virtually any of the full-range speakers out there.  I've compared them.  

Read the reviews - people are replacing their Wilsons, Avantgardes, etc. with these.  

Amazing actually.

I guess this is more of a designers thread than listeners thread.

All I know is - I’m sitting here listening to some of the biggest, best sound I’ve ever heard coming from the diminutive Wavetouch Audio GT’s with a 5+ in. bass driver... and... the bass is superb - big, bold, fast, tight, textured - that you can feel.

The wife says it sounds as good, or better than all my other high-end speakers - her comments precisely were - "how do those little speakers create such a huge sound?" "They sound as good as any of your others."

And that’s in a room about 22’ x 15’ - though it’s lively.

This is my "Giant Killer" system: Cost about $3500 - the GT’s, the Class D Audio amp, Creek OBH-21 passive pre, Sony SA5400es SACD. Just unbelievably, phenomenal sound - as good as my multi-thousand dollar setups.

No - it’s not "earthquake, house-shaking bass"... just the sound of a live upright bass, which is all I want - as a listener... not a designer.

Yes - I not talking about HT movie watching bass or heavy rock bass - just jazz, blues, country, classical, r&b, acoustic bass.

I really don't want my floors and walls to shake - just the sound of a live upright bass, or bass guitar, or live drum kit, etc. - which is what I've got.
