Title: Just bought used RL 1.5...sound muffled. Post by Nirav on 02/28/22 at 15:04:52 I asked the owner, and he said that they weren't used for a few months, and when he did use them it was seldom. Currently, they sound a bit muffled in highs and lows, almost like they aren't truly broken in. I've been running them for a few days about 3 hours per day. My question is, is it because they need to be broken in, in case they haven't been used often, or something else? Thank you in advance. |
Title: Re: Just bought used RL 1.5...sound muffled. Post by HockessinKid on 02/28/22 at 15:22:14 Check the speaker cones and make sure the foam or rubber surrounds are still intact and glued to the cones. If separated, this can cause a muffled sound. HK |

Post by Nirav on 03/01/22 at 16:09:00 @Hockessinkid, The speaker cones and the rubber surrounds are intact. @Lon, The tweeters are operational, sound does come out but waiting for the clarity to kick in which is why i thought i may need another break-in period. It is on wood floors, added the spikes which helped a bit but not as much on the highs. Do you mean the resistors in the inside of the speakers? |
Title: Re: Just bought used RL 1.5...sound muffled. Post by Lon on 03/01/22 at 16:14:54 I meant the resistors at the binding posts at the back. If you are getting sound out of the tweeters some are in place. Though they could be high enough a value to attenuate the tweeter too much for the balance you want to achieve. . . . They may have not broken in originally --IIRC these take a long time to fully break in--and if they sat a few months they could use some time to loosen up again. I think you may be hearing better sound as you put more hours on them. |
Title: Re: Just bought used RL 1.5...sound muffled. Post by Nirav on 03/02/22 at 16:45:21 I looked up the resistors that would be on the binding posts, I didn't receive those with the purchase, I'm using the main bottom binding posts for connection. I do feel a slight difference in sound each day. Read that it sometimes takes about 200 hours to fully break-in, I'm hoping that's it. Thanks for your input. I'll report back in a few weeks. |
Title: Re: Just bought used RL 1.5...sound muffled. Post by Lon on 03/02/22 at 17:05:34 I do believe you will want to add resistors to bridge the upper and lower binding posts and bring the tweeter fully into operation. I used quite high values as I find treble energy irritating--that's me, most others used 5 watt or 10 watt or so 10 ohm resistors. Highly recommend you try that out as it will bring much more to the sound. Or for no attenuation just a wire connection between posts as Archie recommends. |

You are at least using jumpers between the upper and lower binding posts? |

Yes, I owned these for years, and now my best friend in Texas is still using them--he's had them for nine years now. They did take quite a long time to break in, more than 200 hours, more like 500 iirc. But I think the "muffled" sound you are hearing is the ribbon tweeters not having sufficient if any output. |
Title: Re: Just bought used RL 1.5...sound muffled. Post by Nirav on 03/03/22 at 13:45:28 Yes, Jumpers are connected. I didn't receive the resisters from the previous owner, maybe he lost them? Does anyone know the type of resisters it originally came with so i can purchase them. |
Title: Re: Just bought used RL 1.5...sound muffled. Post by Lon on 03/03/22 at 14:10:54 They came with cement 10 ohm resistors I believe, originally I received 5 watt if I remember correctly. They are available on amazon. |
Title: Re: Just bought used RL 1.5...sound muffled. Post by Archie on 03/03/22 at 16:31:41 I used 2.7ohm for my HR1s. I think I may have eventually taken them out completely and ran just with jumpers. I think the HR1s run on a similar principle, that's why I mention them here. |
