Reckhorn D-165 Subwoofer Chassis 175 mm (6.5 inch)

Not tested yet, but don't forsee any problems given the videos on YouTube and the quality of these thing's.These seem far better quality than speakers I've paid much more for.They even come with self tapping hex bolts which are black also.Only a minor annoyance, but one does have a small scratch on the cone.Currently finished my build enough to sound test, and wow.😮These thing's are absolutely insane! In a sealed enclosure, heavily stuffed and acoustic deadening in 38l for 2 of these, the sound is incredible.No need to go ported, with EQ to fix the roll off I can get all the way down to below 30Hz at 0dB to match the other drivers.Musically these are great, these don't just do bass, they really are great for a 3 way speaker. Admittedly you would want to crossover before 700Hz, which I had taken into account and so they match so well.For the money you will not find a better 6.5" for a custom build.As a subwoofer on it's own, I don't doubt it either, but these really are very versatile.These will definitely feature in more of my future builds, these are an overlooked diamond.

Imagine these speakers manufactured by worldwide know brand, they would gain HI END status, they would cost a fortune having multiple awards given. Lucky for me and others is still an HI END speaker at ultra low price, and its got an award from me now. Got them playing as a warmup session in my car just for 8 hours so far. It's a 3 way system where woofers are working in 8L door enclosures at 50Hz-400Hz range, comparing to other woofers I've had (morel,rainbow,vibe,steg,rf,intertechnik,diamond) this is absolutely number 1 (dynamics,quality,sound pressure). I know some may say hold on a minute this is subwoofer not a woofer, yes thats right and it's best choice for 3 way application. I will never go back to classic woofers. They can go very very low in just 8 liter box with plenty of freshness and dynamics, you can't go wrong with them for sure. 10/10 for quality/price and this amazing bass response where you don't really need subwoofer :)

Amazing subwoofer!!! Deep bass !!!
