Sounds real audio...scan Speak has been around since 1970 and spends just as much on their research and development. They’re under an umbrella that also owns audio technology (skanning) and dynaudio. Their drivers are used in commercial designs costing several times over $100,000 and get the "I want to mortgage my house for these" type of reviews. Their D3004 tweeter (fabric and especially their berrylium) is usually used when someone wants the best tweeter on earth. Skanning woofers are used in the most expensive Sonus Faber speakers. Many people consider Scan Speak’s 4.5" midrange as the best on earth. In a few years once I feel comfortable to drop about $12,500 on speakers I’m building an 11 speaker atmos setup with DBX Venu loudspeaker management components (digital crossover, equalization, etc all in one device) which far exceeds even the best most expensive passive crossover technology in fideltiy by a lot and costs a fraction the price. I will laugh and get off from the fact that people pay hundreds of thousands of dollars for performance less than that I’ll have. I’d build the subwoofer too but SVS actually did something very special with the PB16 ultra at a reasonable price. Dual of them makes Wilson Thor’s Hammer and subwoofers of the likes seem like ginger beer for 90% less. I’ll just have to pay an expert to setup the DBXs and make me some designs for cabinets. Far far easier than designing a crossover. Far easier. Worth it!
I forgot to mention that in the title...designing a fantastic cabinet isn’t all that complex. You could pay one of the few DIY experts that are on the Internet such as HTGUIDE some money to design cabinets for you and then just use an active crossover. That’s one of the advantages about DIY is using loudspeaker management devices like DBX Venu 360s. No passive crossover on earth can touch them and having an expert set them up in an afternoon and it’s easy peasy japanesey. You’d have complete control over your loudspealer with 31 band or parametric equalizers and crossovers and set delays...basically a true flat response way better than passive and without the passive components degrading the sound quality which they do not matter how good they are. Build speakers not only comparable to 6 figure speakers but better and it's not....that.....hard. But by all means sheep waste your money on $20,000 or $50,000 speakers and feel super cool instead of having something better for a few thousand dollars that requires a few hours of fun work.
