Maybe my perspective on the blown tweeter situation is a little upside down…but here goes. Tekton loudspeakers are not the same as the Cerwin Vegas of the 80’s and 90’s…speakers that would take abuse and where the sole objective was volume. Tektons are audiophile loudspeakers that were designed to be extremely musical and highly efficient. The will take a lot of clean power and will play very loud. I’m sure that Eric would say that his objective was sound quality and not sound pressure level. They do not have built in protection and as such, the rules we all know about apply; tweeters can be destroyed by too much power, overheating by playing too loud, too long, and clipped power.
Here is the problem. Many loudspeakers start to protest when they get close to the breaking point…you get a warning with strain and harshness and you can back off before damage occurs. MLores, Lores, Enzos, and Pendragons can play so loud so cleanly that it is very difficult to know when they are at the edge. In this respect, I think it speaks well to the overall design that they can play so loud and sound so good and yet so few tweeters have been blown…on the other hand, maybe not too many of us listen for long periods of time at over 110db?
One final note, I own a pair of Lores. They are rated to be able to take 200 Watts, which would put them somewhere over 110db at a 12’ listening distance (http://tektondesign.com/lore.html
). I’m driving them with a Crown XLS Drivecore 2000 which puts out 375 RMS/channel into 8 ohms. I’d much rather have a lot of extra headroom than risk clipping…and if you are going to be playing discs like Terarc’s “Chiller”, you better have a lot of clean power to spare.
First off, I gave you a thumbs up for your very factual, logical, sincere, and passionate post.
However, the height of your logic does not outshine the depth of my conviction that there exixts some deficiency in the Lores.
I cannot prove to you that my amps were not clipping, or faulty in some other way. I certainly don't believe I ever heard 110 DB, or even anything over 98, if that.
I will only re-state that, 50 years ago, I first mounted a pair of raw full-range drivers in the corners of my kid's room sliding door closet and hooked them up to to a heathkit tube amp. Little did I know I had inadvertently created an infinite baffle system
. Later in life, I moved on to AR-2A's, Baby Advents, Bose 901's, 1970's 3-way Mitsubishis-bi-amping with dual-mono Mitsu amps. Then on to small Magneplanars, larger Maggies--coupled with Dahlquist passive x-overs and subs--Snell monitors on stands filled with lead shot---VMPS Supertowers--and a half dozen other speakers I cannot even remember right now. A lot of that gear was bi-amped with Carver 1.5 Magnetic Field Amps. As mentioned before, the only driver I ever blew was one woofer in that pair of Snell monitors. Ever, mind you, please.
For over 5 years of my pre-Lore Life, I had a pair of Fried Q-5's, 8 in 2-ways (coupled with a pair of low-end 12 in C.V. servo subs) Drove this combo as loud as I liked--never a single problem. Still, possibly the best thing I have ever heard. Sound good on almost everything, while Lore's only like some perfect recordings... Center image like nothing else on the planet---floats a voice in the center in midair...
Now--it gets interesting. ----Given the Lore tweeter controversy (I replaced 3 of them to-date) I decided to try something. I pulled out a pair or RS-1000'S out of the closet.
(size of a loaf of bread---Infi polycell tweets with 4 in woofers) Unused, un-needed--unwanted--cannot even get 50 bucks for them on ebay.
Hooked them up instead of the Lore's. Same Integra ADM 2.1 Power Amp. Same twin subs. Mercilessly cranked up the volume (Gee-those tiny Infis sounded good with a sub!!)
It took a good 90 minutes of Tribe 5 and some other mix of very dynamic accoustic guitar with disco electronic beat--to finally fuse the woofer voice coils into oblivion--as anticipated.
Guess what: Those little 30 year old polycell infi tweeters are still working just fine. The woofers took the brunt of the power-zero tweeter damage.
Got an explanation for that?
So, allow me now to take off the audio hat and put on my consumer hat.
You pay a grand for a pair of speakers that are highly touted on severeal websites. As a consumer, I would expect that they play loud, and sound great, right? And keep on ticking ??
Or, are these some delicate, over-sensitive thing. Like one of those breeds of dogs, that always gets sick---or, like a 1960's Frerrari----nice, but don't go more than 10 miles out of town?
I did own a 1956 Austin Healey, with Lucas ignition (Prince of Darkness). Kind of remids me of the Lore problem. Finally converted it to a 283 Chevy--no more problems...
I just took delivery of a pair of Definive Techology Mythos STS.
Lores are going on Ebay soon.Lore experience for me, after blowing tweets : Like a lover that you caught cheating on you--still nice--but never the same...
DefTech Mythos STS: The perfect lover. Play loud. No problem with my (ill-accused amps). Bass down to the bottom of the planet.
I will get rid of my subs. There is no sub I could afford that could match or improve on the palpable bass the STS's can put out. It is prolific, at times, more a feeling at the seat of your pants, rather than a sound. Have not heard anything near to this since I sold my VMPS Supertowers back in 1996.
Again, thanks for your post--hope to get a reply
