Upgrade HF Driver Tweeter on Alto TS215

I decided to go big for the JBL D220Ti and *Upgrade the HF driver for TS-215* Wich will fit on a TS-210/212 because of the lack of a handle bar. On the TS-215 will not fit at all.So I decided to cut part of the handle bar to make it fit. Cut at least at inch of the bottom and the rest of the inner shell. Once that's done you are able to glue it back and add some silicone to avoid any air scape from the woofer and have a tight seal. The job looks a bit sloopy as I did not own a proper cutter rotary tool I post a picture of the final product later on. I decided to cut it off since warranty was expired and also to spend on a replacement that will last a year or less or buy a newer one why not. Try this at your own risk.

PS: I have two Altos and side to side the quality is amazing at the same settings and volume the new driver surpass the factory one!! Really Happy.

    The driver that Alto use will be of a budget variety, one probably costing £20, using a JBL compression driver will be a lot better same goes for the 15" bass driver, I helped a friend upgrade all 4 of his cabinets using an Eminence Kappa Pro 15, ok it was 3 times the price of the Alto original but definitely worth the cost, we converted 2 cabinets first and compared them with the 2 as standard and the difference was so much better, the only drawback being slightly heavier, all 4 cabinets were carefully internally lined with more acoustic lining to prevent standing waves giving a more natural sound, The internal space of a cabinet should be anechoic but most manufactures line the cabinet with the bare minimum of acoustic wadding to make it sound louder but by doing so will sacrifice a quality sound.
    The ultimate test whilst the bass driver is removed is to shout as loud as you can inside any cabinet and it should be sounding very dead, no reverb, once the new loudspeaker is fitted all you want to hear is the sound from the front of the loudspeaker not the reverb from the back, that is the reason for deadening the internal side of the cabinet, what you don't want hear is a sound that is a micro second delay from the rear of the driver mixing with front colouring the sound as they say.
    Alto make a nice looking cabinet but what do you expect for the money, if they fitted more expensive drivers you wouldn't buy them as the cost will be double. Good luck.

    • My view is these have 4 times the power handling capacity than the original drivers—so I figure it is worth a shot. As you mentioned, this is my “light rig” for wedding work so I bought these with the aim of something super light that looked clean/new-ish.

      If I were building a passive system and pairing an amp to it I would be shooting for 2xs the amp capacity as driver for headroom/pairing so I’m less concerned with overpowering the driver than it being a really poorly built component in the first place. I suspect the reasons these things blow are multiple—people not understanding the mic/line mark ion the gain, the component itself being light/having low handling capacity, the system being overdrive because a single 1” driver is limited in output, and overheating from a combination of everything.

      Good call out on whomever mentioned adding insulation to the cabinet in this forum, they basically just put one big chunk of foam behind the woofer and called it a day. I added some poly fill in the upper corners/walls with some glue and it seems less boomy than before. I’ll update if the Selenium 202 horns blow or give feedback after I’ve put some substantial wear on them.
    • Any updates on how it worked with the 202ti horns? Thinking of doing the same.

  • So far still going strong. I've done about 9 gigs with them, a couple outdoors with extended heat conditions. They add some weight to the cabinet--the original NEO drivers weigh next to nothing.

    Sound quality still good, durability still good for the limited use. I use these mostly for weddings etc so they don't see a lot of extreme use. I feel more confident having them in both cabinets than the stock ones--admittedly I've only had 1 horn blow before changing these out.

  • One caution--the Selenium/JBL horn has a metal screw in housing instead of the plastic one the stock horns use. These absolutely fit, but just barely and you need to make certain you line the horn up perfectly. I found it easiest to lay the speaker on its face and screw in from the top down. When I tried to do it standing up I realized I was cross threading it. Obviously--a metal housing being screwed into a plastic cabinet will win every time if you don't line it up correctly. Once you line it up correctly the driver will rub the foam along the cabinet as you screw it in, but there is a tiny bit of clearance once it is all the way down.

  • Andrew Bishop, The fear I have of using this driver is the rating being only 70 watts (140w program) albeit will be more efficient will need to be attenuated being the HF amplifier in the TS215 boasts 350 watts, as I say I have never heard of any HF driver capable of taking such input power especially having to be small enough to fit in the cabinet on the end of their horn, you will have to purchase a larger horn to take the bigger driver, the best way is to not over drive the top end and save money.

  • I’d be really reluctant to cut the top of the cabinet to make the larger 220 fit, even repaired it seems like a likely source of rattle/noise.

    • Sir I searched and made inquiries here in the Philippines but unfortunately,there's no available of that item. Is it okay or compatible if I'm gonna buy the Eminence PSD:2002S-8 as an alternative for JBL D202ti?
    • The body on that eminence unit is too large. I think they had one that measured close. You need to ensure the OD of the magnet housing is the same or less than the JBL or it won’t fit because it will hit the housing. I think there is an Eminence unit that will work
