Scott S. - HiVi 3.1 upgrade

This is what DIY Audio is all about. Scott S, talks briefly about how he transformed an already good HiVi speaker kit into a really great system.
If you can still find these kits, they are well worth the investment, and with a few crossover modifications, they are excellent speakers - rivaling some audiophile offerings.

I did it. I used his perfectionist crossover build. These are the best speakers I’ve ever heard! End game speakers for me

[@fototechnologies]

Scott, Thank you for your help. I built these using the perfectionist approach and they are spot on to my ears. I'm really tempted to build a set with 10" passive radiators on the sides but I need to work on my measuring skills. I rotored out the box for the Mid to fit flush. I used a grinder to make on the mid driver to make it fit flush. They outshine speakers in the $1000 range.

[@chefbink61]

These are some really great DIY speakers and they are well worth the money and time. I would highly recommend Scotts perfectionist mod if you plan on building a set. Thanks Scott!!

wow, they are big

[@TheChuckster402]

Scott, the mid range / tweeter sounds tinny sometimes with recorded spoken voices, they sound like they're on a telephone. Singing voices sound perfectly fine though. Is this a limitation of the drivers, is it the BBC curve, is it the phases / time alignment, is it the recording, or is it the acoustics of my room? Have you noticed this with your modded 3.1?

[@TheChuckster402]

Update: I noticed that this effect went away in a different room with a better amp.

[@purplerider2362]

I have these connected to a 1200 watt amp they sound spectacular

[@kennethkennelty7652]

Link to Scott's channel?

[@int_pro]

Would it be possible to make them self contained with built in amp and Bluetooth? Would be awesome!

[@KL-tn1xc]

that's certainly possible, you can even leave the crossover out and use a dsp crossover insead if you use a icepower or hypex plate amp, it'd be more expensive though.

[@lapalomatv1474]

The speakers sound bad with the original crossover. Does Scott's modification really bring the loudspeaker to a high end level?

[@zacharyybarra7676]

I made these a few months ago. I agree with the original crossover -- they are extremely fatiguing. After I did the crossover mod mentioned above (roughly $30 in parts) I do not find them overly bright anymore, just detailed and with great clarity. I have noticed however that on certain hip-hop tracks with really low bass -- the bass driver will chuff out of the space between the cone and phase plug. Only at high volumes and only on extremely low bass frequecies. I plan on buying a minidsp HD 2x4 to cut off such low frequecies to the 3.1a's and send them only to the Subwoofer. I imagine after that I wont find any complaint with these speakers. They image great, far away from the wall they sound spacious and open.
