Rated 4 out of 5 by from Wow, now that's value!Got these to try a lower sensitivity tweet... glad I did, thay are better than expected. These 2-way RCA 40-5022 are close to fullrange with supertweeter, and now sound even better!

Rated 4 out of 5 by from Did the job!I needed replacement tweeters for my M-audio DX-4 powered monitors. Since they were going into my teenage daughters bedroom I wasn't too concerned about replicating the tweeters exactly. These tweeters were a perfect fit into the existing cutout and were remarkably close in performance. 99 cents well spent!

Rated 5 out of 5 by from Sounded goodBought 2 of these and used 4.7 mf capacitors and 2 292-405 woofers for an old set of Jensen bookshelf speakers that were my Dad's. Although the cabinets were twice the size of the sealed box recommended size for the woofers they still sounded pretty good.

Rated 4 out of 5 by from Great for old PSB AlphasDropped these into some old PSB Alphas for the garage. Sound great.

Rated 4 out of 5 by from Replaced tweeters in Bose 201 Series IIIThese Speakers definitely did the job at less than $2 each. Just note.... the small lead is the negative, I used the far positive across the magnet and not the close one bypassing the use of the resistor. Be careful and use minimal time in soldering the connections as they will QUICKLY melt at the speaker connection point. If this happens, you may have to reset the mount with your solder iron quickly heating it up and melting the plastic and having the speaker powered up to make sure a new position connection is made. It happened to both my speaker. I also had to re-drill three new holes. Other than that, the speakers sound perfect in my Bose and look great too. Great replacements that made my Bose come alive again!

I am looking to use this tweeter with the Tectonic driver P/N 297-2156. Is there a stock crossover available from parts express? If not do you have suggestions?

Asked by: Big Micky
Unfortunately we do not have a dedicated two way crossover that is high enough to work safely with this tweeter. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

Is there anyway I can get the range of this tweeter down to 5500 hz?

Asked by: Realquizzz
Unfortunately no, with an Fs that high the safest crossover point for this tweeter would be about 8,500 Hz assuming second order.

Hi....I need to replace tweeters and woofers in my old Royal Sound S6060 sealed boxes. As you know they use the same tweeter (SD-13) and woofer (1218) that the old Realistic 7's used. Would you have these or replacements which would work? Many thanks!

Asked by: Quahog47
Unfortunately we do not have a cross reference available for this type of thing. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

hi will this fit a Yamaha N 6490 bookshelf speaker?

Asked by: SMF63
Unfortunately we do not have a cross reference guide for speaker sizes. You will have to verify the dimensions with the cutout the enclosure has to see if it will fit. As long as the impedance matches the original is will work without any crossover mods.

Is this 8 ohm with the resistor in series?

Asked by: j_doggggggggggg
The DCR is 8.27 with the resistor in series, this can still be classified as an 8 ohm load.
