Summary: They are mounted in an unusual way; The shelf holding the components is above the TV, near the ceiling. A painted length of angle iron is mounted beneath the shelf - 'V' up. The front edge of the speakers balance on a soft strip on velcro in the 'V', angled about 30º downward. The back is stabilized with Snaptoggles in the wall, into which are short lengths of threaded rod with locknuts at each end. Very sturdy, and they look like they're floating!
Pros: Paired the Def Tec 450s with Integra 40.4 Stereo receiver (and, no, Onkyo and Integra are not the same; Integra is made with better quality components - notably upgraded capacitors). Back to the 450s: As noted almost ubiquitously, the 450s lean toward being bright - but it is slight. And they clearly need broken-in over a long period - as is normal. The response has flattened considerably in just two weeks and in a few months of daily use they should produce sound com...
Cons: The 450s sound vaguely muddy; mostly a break-in deficiency.
Summary: These are just amazing sounding speakers I have had these for a few days so I am still un the brake in stage these sound awsome the high and mids are clear and the bass from the radiator is powerful its to bad definitive quite making the studio monator series like these these are like the old power monator series speakers I would highly recommended these and the 350s the smaller model I have a pair of 450 and 350s both are incredable sounding speakers.
Summary: I replaced my Klipsch RF-82 II with these SM 450 and no regret. Wifey said these speakers sound even better than the giant RF-82's speakers :-) The best part is the price, under $250 a pair on the egg website and they matches with my PC2000 center; PM1000's back surrounds; SR-8040BP's side surrounds and SuperCube 2000. That completed my 7.1. The SM450 sounds amazing as front 2 channel when listen to music too.
Pros: really nice sound stage and coverage of the spectrum. took quite a while to open up though, so give them some time to break in (like several months with infrequent use) before you judge them. So it took some time, which you could speed up if you used them more than I do. But now they sound fantastic. I have a 100w per channel carver amp and these sound very good so I think they need some power to sound their best.
Cons: the woofer does not have the phase plug that the more expensive models do. but the sound is still very detailed and rich.
Summary: These speakers for under 400 dollars for the pair are the best value on the planet. They are even better than the KEF q300s and Klipsch Reference RB61 II! These also look fantastic, too. Dont think twice...these are discontinued...for the price of about 350, these are perfect for front speakers in a 10 x 12 room. Get these ...no questions asked. I hav e these beauties hooked up to an Onkyo A9050 integrated amp, Marantz cd 5004 and Music Hall mmf5-se turntable.
Summary: I have a small man cave with a vintage Kenwood KR6600 receiver. Was considering putting an ols pair of Bose 901 Serie IV speakers that I own down there, But just did not have the space and the walnut cabinets did not fit teh decor. I'm a big fan of Bose and considered getting a new pair of 301's. But after doing some shopping and reading some reviews I took a chance on these DT 450's, Very glad I did. They look great, and they sound as good as they look.
Summary: These are by far the best sounding speakers I have ever owned in the bookshelf realm. The sound stage and imaging that these speakers provide is just outstanding. The 20 LB weight of each speaker stunned me when I first picked one up! Match these up with the Definitive C/L/R 2002 or the new HD 8040 center for a great timber matched sound. I bought two pairs of these back when they were on sale for only $280 a pair!
Pros: Well built MDF cabinets that are sealed and not ported! Very well built 6 1/2" mid-bass driver with real rubber surround. A 10" passive radiator that really helps with the overall bass response. A high end 1" aluminum dome tweeter that's been annealed for a less bright sound. Fantastic soundstage and imaging! Some of the best looking speakers I have ever owned with the main sock speaker grill and the two 1 14" piano black end caps. Customer service that's second to no...
Cons: This is really not a con since it can be corrected but these speakers are a little bit on the bright side. People with really good hearing will notice this. Older people with some high end sound loss will not!
