How To Make Cheap Speakers Sound Unbelievable.

[@marcopignone9386]

I like that you don't oversell the impact of the no-res. That's honest salesmanship. I tried your no res on Klipsch Forte IIs and I definitely noticed a difference and was glad I did it. Whether it's a good "value" is subjective, of course, but if you like your speakers already I think it makes sense in most cases depending on the build quality. It was also just fun to see what difference it made as I was skeptical that it would make any noticeable improvement.

[@NosEL34]

I think you make a good point about already liking your speakers. Awhile back I put $400 worth of Iso-Pucks under some speakers. The improvement was noticeable so I just couldn't return them. But I already liked the speakers..I wasn't trying to fix them in some sort of way. Was it a good value? I don't know..but I liked the results.

[@TuiCatNZ]

Can't wait for you to do a dissection of the Polk r700 tower!

[@NosEL34]

I bought a pair of these couple years ago for under $600 new. Not bad. They are worthy of upgrading/modding imo. I put oversized iso-pucks under them which helped a bit. I still have the larger R700..they have some similar issues. I took a look at the R700 cross overs...whole lot of parts involved. Expensive upgrade. If you can set the R700's up right (have the space) they are good for under $2k mainstream speakers. I enjoy them but already looking for something different. I like trying different speakers

I've always suspected that production drivers vary significantly from what manufacturers used to design the speaker.

[@Evolved_ue7]

[@MechAdv]

Quick question, I’ve noticed in a lot of your crossover designs that the horizontal off axis response loses more midrange energy than the original, causing a humped up response at 3khz at the widest dispersion. It’s odd to me because that area of the FR should be well past the crossover point, and I would expect the tweeter radiation pattern to narrow somewhat linearly from bottom to top of the treble region, and then fall off a cliff above 10khz at 45deg and beyond. Can the crossover components in the tweeter circuit affect radiation pattern, or is it more of woofer beaming issue. Thanks.

[@dannyrichie9743]

As the tweeter plays lower the output levels exceed the plane of the front baffle and begin to reflect off of the baffle. So they pick up some surface reflections from the baffle.

[@MechAdv]

@@dannyrichie9743 Understood, but I’m still not understanding so why is there less energy in the crossover region at your widest data point. I’d expect that vertically but not horizontally. Especially when the original has a more linear roll off at wider listening angles.

[@JohnSheerin]

@@MechAdvThe woofer's pattern is narrowing at the top end of its range in the new crossover. You can see the same narrowing (roughly) in the before horizontal response in the 1-2kHz range. The farthest off axis measurement is down maybe 4dB from on-axis in both cases. But in the original crossover the system more or less keeps a constant beam width from 1.5kHz up to ~7kHz. It's possible the original designer prioritized the evenness of the horizontal beam width over other factors and pushed the crossover up until the beam width of the tweeter more or less matched the woofer over that wider frequency range. The new crossover is going to emphasize the 2.5-4kHz range a bit more due to exciting the reverberant field of a room a bit more in that range. Personally I'm not sure I would make that decision as I like less output in that range.

[@MechAdv]

@@JohnSheerin I tend to be quite sensitive to the 3-4Khz region, and will typically EQ it down if a speaker does not have a downward sloping in room response. I also tend to do stuff around the house while I’m listening to music, and I’m not always seated in the sweet spot when we’re watching movies and shows. I was just trying to figure out is this behavior that I’ve seen in a few of these crossover designs by Danny was specifically a trade-off that he was making to accomplish a more flat on axis response.

The verticle off axisis is certainly an improvement, but the rest to me seems personal preference. The Polks are designed to have a certain sound that makes them a bit easier to listen to (I have these, and its true, they are quite pleasant and easy to listen to), and that appealing character will be reduced with these changes, unfortunately (IMO, as others make prefer that). Powered monitors are probably better for people who like a flatter sound signature or to control the speaker more.

[@dannyrichie9743]

Not really. A smoother response curve is just a small part of this upgrade. The major improvements in this case are in clarity, detail levels, a more natural vocal region, less smearing, better imaging, a deeper sound stage, a more layered sound stage, etc.

[@wolfblaide]

Hmm, really. Half of those things you mention are just the response curve. Sure, you'll get slightly better sound maybe with better quality parts, but how much is audible to most people is debateable. And like I said, you then lose the point of the speaker. People should really consider getting a much better (and probably cheaper) flat result by buying powered monitors if that is what they are seeking.

[@shipsahoy1793]

Polk should have stuck with their old passive radiator designs, and improved the development of those, instead of the backwards step to ported design. Polk has also historically been cheap about the design components ultimately used in volume manufacturing. I don't think that was their intention in the 70's, but it went that route after too many consumers were unwilling or unable to pay the high prices required for carefully crafted speaker designs.

In terms of notch filters, why are companies designing speakers that produce unwanted peaks? And releasing them with filters on to mask the problem? Seems ludicrous. Your services are different, customers are asking for you to increase the accuracy and balanced response, but the manufacturers?!

410-489$Upgrade for a new pair 599€ 🤔🤔🤔

[@pandstar]

But the end results will yield a speaker with sound quality worth quite a bit more than the $1000.00 spent. And even if one were to take that $1000.00 for the speakers and the upgrade kit, and buy a set of, lets say, $1500.00 - $2000.00 speakers, you will still get a speaker with crappy crossover parts, that will still lack the detail, better imaging and soundstage, that this upgrade will get you. So, there will still be more compromise with a more expensive speaker, that there will be with these speakers upgraded.

[@DodgyBrothersEngineering]

@@pandstarand this is what a lot of people don't get. They get sucked in by a slick salesman peddling a particular brand, or justifying the cost of these more expensive speakers that we have, but seldom does anyone look past the lipstick on the pig. I have owned several sets of speakers costing 5 figures, and inside them you expect to see something wonderful in terms of a crossover and box design, but it seems the majority of the money is spent on the outside of the box to justify the high price, while mediocre parts are used inside. That is why over a decade ago I went DIY to get real value for money. I will never produce anything that looks like 5 figure looks, but I can produce something that has 6 figure sound. In fact the drivers I am using are featured in several 6 figure speakers.

Great fix and clearly invested a lot of time on these, but speakers that low end are not really worth upgrading. Get rid and get something better.

[@gotchagoing4905]

I would also suggest after getting rid of those speakers buy one (a pair) of GR's speaker kits. When my small shop is finished, (if a shop is ever finished), that is what I plan to do. I won't even consider any others, be it kit or ready made. I decided that before building a shop at home. What was I thinking...

I wont be too harsh with you as after all you did menage to address part of the problem and lower THD but more on twitter side along with ringing at 1100 Hz to a expense of lower impedance which is not acceptable to me foliage to 3 Ohms. Why on earth you didn't add high pass just above Fb I will never understand. Simply put for less than upgrade cost you can buy Elac's DBR62's and Andi did box great for minimal budget and when crsssed at Fs 120 hz with pair of sub's those have waterfal to desire.

[@dannyrichie9743]

We have had a handful of the Elac's in house. Andrew did a great job with the design, but they were REALLY built to a price point and need an upgrade worse then the Polk's.

[@lazarprodanovic8373]

@@dannyrichie9743 yes but he had peanuts budget and most of it went to cabinet which is deacent. I play with digital crossovers which don't change impedance. What's the use of better caps and components if they will fail faster thanks to higher operating temperature thanks to increased amperage. Not complaining to you just saying. Another point is individually taking into account actual space when doing digital one's but it's not for everyone nor will ever be. Have a nice time and thanks for the answer.

Love your videos but in this case you’re wrong about the port.

Nope. This port is a gimmick. You can simply make the port a little bigger in diameter and equally bigger in length, to keep the tuning the same, and the air velocity would be reduced and there is less port noise.
