For people that do enjoy music at a normal/ high level, these speakers are excellent.They are one on each front door oh my Chevy Tahoe. Simply good quality sound and power!
MCM, in their suggestions on product reviews, said to be detailed. After this, I wouldn't be surprised if that was changed to brief. I could have written a lengthy dissertation of several thousand words but I took pity on the reader(s).Incredible little loudspeaker; I was impressed at first glance. Although an actual listening test has yet to be performed, I feel that my 40 plus years designing loudspeaker systems can honestly say these fellas will sound great. I plan to try them in an MTM (midrange-tweeter-midrange) vertical arrangement. A straight axis exponential horn design is also in the works.The speaker was tested on two computer simulation programs, both of which are used by professionals and manufacturers. For a closed box, 0.151 ft^3 will give a response with a 3 dB down point of 172 hz.;a 200 hz second order high pass filter is recommended. For a vented enclosure, 0.33 ft^3 is recommended. With a vent normalized for 0.75 inch cabinet wall thickness, an area of 5.9 in^2 will tune the cabinet (Fb) to 119 hz with a 3 db down point of 98 hz. With a 3 inch diameter vent, a tunnel length of 1.18 inch is needed. (1 and 3/16 inch) A similar high pass filter here is also recommended. Keep in mind, this is a midrange unit, NOT a woofer.Measurements of maximum diaphragm excursion showed the first sign of sine wave distortion occuring at 4mm, 27.1v at the speaker terminals, 29.7w. The amp clipped at 31w. At 4mm diaphragm excursion, the SPL was 108 dB at 1 meter. This equates to 96 dB, 1w/1m. That 4mm is in one direction from rest point to maximum out from the frame. Bidirectional excursion is 8mm.Near field (simulated anechoic gated response) and outdoor responses showed a deviation from perfectly flat of 7 dB, peak to trough, one third octave smoothed. This is consistent with most musical instrument speakers of similar design and application and even many 'high end boutique priced' units.Most of my work in speaker design has been with high end audio systems but over the years, it was discovered that a good musical instrument speaker is sometimes better suited as they have a way of placing the musicians in your listening room, especially if you like drums and percussion. A similar set of 7 inch mids, actually a coaxial was designed and much to the surprise of a few audio buff friends, these things really kicked butt. Sometimes one just has to get on that volume control if ya wanna hear some music the way it was heard at a live performance.I'm partial to horns but a well designed horn even for a midrange to get down to 150 hz is too large for the average room. Horns will deiver an extra 10 dB output as an identical driver in a bass reflex or closed box and 10 dB is a power ratio of 10:1. Also, due to their efficiency, horns have high transient response; tighter bass and very realistic drum rim shots. One has been designed for a guitar (lead) player friend and unloads at 185 hz. It's a little over 3 feet long and the mouth measures 29 by 29 inches. It's driven by a 12 inch speaker. A smaller speaker such as this would add another foot to the length but listening to something like Dave Brubeck's "Take Five" from a horn loaded system will give ya goosebumps.After seeing these little guys, I wished I had bought 4 instead of two. That wish is about to be fulfilled.A side note. Keep in mind that the above numbers are purely academic. Despite the high quality of the instrumentation at my disposal, those things don't have ears. The listener is the final critic and that is purely subjective. It has been said that one man's meat is another man's poison. (Lucretius, circa first century, BC)
Awesome folks, huge stock and it's actually in stock (WAC), fast shipping. One of my few favorites for electronics and parts. A+ Solid.
