There have been four in the last few months, and they are as different as night and day, ranging from an under-$150 standmount to a high end WMTMW, with a single driver thrown in just for fun.

The best, and not coincidentally the most expensive, is the Selah Audio Texas Revelator Tower, a $1,500 2.5-way kit featuring all Scan Speak Revelator drivers. I can still be contented with speakers whose drivers cost less than $220/ea, but there is a correlation between driver cost and sound quality. I've learned this through my membership in the Houston Audio Society, where the typical member's system cost upward of $20K, and the systems with the better speakers offer a clearly audible improvement is soundstage, resolution and detail. I wanted that, but without a $5K+ price tag, and I got it in the TRT's. They aren't as impressive as the XT8 line arrays in the downstairs system, but overall they offer the best sound of any speaker I have owned.

The most unusual is the Jim Griffin designed full range single driver mass loaded transmission line bipoles. This is my second build of these unusual speakers, which have a unique and pleasing sound of their own. My only criticism of these speakers is the lack of that sparkle you hear with a good two-way, and I'll probably add a supertweeter with a single cap crossover.

My sons are members of an alternative rock band, and few high end home audio speakers are capable of playing at the levels I hear when Low Rent (that's the band's name) is playing to a crowd of 60 to 80 people at Hanover's bar in Pflugerville Texas.

Enter the Khanspires, a three way WMTMW using all Dayton reference series drivers, and suddenly you have a wonderful combination of high end clarity, sensiitivity and ability to play loud. Cool!

And finally, something I've been doing for my musician friends who typically have really bad home audio systems (plastic speakers) and not a lot of money for upgrading. It's a slightly modified version of the Parts Express BR-1, with some added bracing to control the resonances of the 5/8" enclosure walls. This speaker kit sells for about $150. It excels at nothing, but you can still get some very nice sound, even when it's used with a $100 Best Buy Insignia two channel receiver and a $60 DVD player.
