which speaker to buy

Cerwyn Vega 215 get some KTM/redbull stickers to plaster all over them and call it a job well done!

I know Klipsh might handle the power.  However, you better like the high frequencies  I would imagine they might have to large in size.  A pair of REL S2 SHO's would be able to handle the low end because they are amplified.

I will be curious to find out what this group comes up with.  However, I think you should find out if they are dealers because they will want to sell you something.  I would not purchase any speaker without auditioning them that's for sure.  

You also did not mention room size and price range.  I am sure the knowledge in this group can be a big help.

actually, my son doe's have a pair of klipsh speakers. i don't know what model it is. only reason he want's to bridge is because he has no funds to buy an amplifier to suit his needs. he want's to bridge to see how much louder his klipsh speakers will go. when i went to see led zeppilin at the forum in l.a. ca. back in the 70's, it was loud! i think he want's to hear his music that loud!!!

Tekton.  Eric makes his speakers to capture the dynamics of a live performance.  Theres a video on you tube where he explains how he’d listen to live performances and then try to build his speakers to reproduce that style of dynamics.  Most, if not all of his speakers use large paper drivers that look like pro audio drivers for the midbass and bass frequencies. 

First, I am a Tekton owner. I have a set of towers that I like very much. At one time I pushed many others towards Eric's products. I no longer do that. I no longer recommend Tekton. Not for a purchase new anyway. 
Though the Tekton speakers are quite good for the money I no longer feel that they are a good company to do business with. It does not matter how good your product is if you can not complete orders. Many have waited months (or more) for just the grills that were purchased with the original order. Some orders for speakers without grills are taking 6 months or more to be delivered. Emails are not responded to and phone calls go unreturned. It seems between his IRL project, racing interest and life in general Eric is no longer able to keep up.
It doesn't matter how good a product is if your company is not there to support it. 
Here's where the "not for a new purchase anyway" part comes in. 
On the used market a 1 to 2 year old Tekton brings roughly 60% to 70% of original purchase price. I have seen them for less. I regularly watch the market because I WILL purchase used. You just have to decide exactly which one you want and watch for it.
