Product Details

Dayton Audio RS621 Speaker Kit w/o Cabinet

The compact RS621 speaker fits Dayton Audio sound quality into tight spots. It excels in home theater surround systems, or as a main speaker placed in smaller listening rooms. The Dayton Reference Series RS150-8 6" woofer provides robust, high-impact bass in any application. A Reference Series RS28A-4 1-1/8" aluminum dome tweeter is exquisitely matched to the woofer, thanks to the well thought-out dedicated crossover network. The net result is a small, high-resolution package that will deliver faithful, detailed sound reproduction. A user-supplied 0.25 cu. ft. cabinet is required to complete this kit – all other components are included. The perfect speaker project for anyone who enjoys designing and constructing their own enclosures! The RS621 is also available with cabinet included, in a variety of styles and finishes.

Dayton Audio RS621 Speaker Kit w/o Cabinet
Dayton Audio RS621 Speaker Kit w/o Cabinet is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Will stick to the store bought speakers (can hear before purchase) instead of gambling on hopes.Not my best music investment.First off, I already own a descent set of Polk Audio 5.25” book shelves which sound great with any amplifier. A bit boomy perhaps around 100-150 hertz but lots of heart. With a goal of bright yet pure sound as budget and wife friendly size permits, a great set of bookshelves was my demographic. For $300 per set and having a wood shop set up, I thought these were my answer. Additionally, I live in Canada so these cost an extra $50 delivery; bring in parts and materials, these ran me a final tab just under $400 completed.Assuming the RS150’s were actually 6” mid woofers as …stated in description… I was very disappointed when pulling them out of the box, they are actually 5.25” (which as I stated above I already own; original goal was also to step up woofer size). These have less cone area than Dayton Audio’s own 5.25”s (Dayton Audio DC130BS-4 5-1/4"= 93.3cm sq {and more efficient} versus the RS150’s 84.9 cm sq). The false advertising doesn't make much sense, but if your preferred driver is a 6” mid woofer than you have to purchase Dayton’s apparent 7” driver. I should have noticed this before, but too excited to study every detail at time of checkout.I decided on the ported version to up the efficiency and low end response using these ports ( Placing the ports on the front was also the wrong choice, port noise is quite noticeable so if plan on creating the ported enclosure version, put port on back. Covering the port subtracts a mass amount of db’s at lower frequency’s and raises Fs, with high roll off below a 100hertz.Sound: perhaps my ears are too accustomed to the brighter Polks or my Onkyo 7.2 amp is better mated to more lively or rather colored speakers, but I am as disappointed of the sound as I was when first opening the smaller than expected drivers. They are extremely laid back with no depth of centre, all linear (like setting audessy feature on amp to full, no instrument impales the ears over any other) . Bass is transparent, midrange dull and highs about as bright as a nightlight, though 0 grain and no distortion; which was the slogan for these drivers. Having aluminum cones, I thought these would deliver a nice metallic tone, but quite the opposite. Only used these for a couple hours now and instructions recommend 30 hours break in, so here’s hoping for better results. To the readers silently blaming my craftsmanship resulting in my protests, I followed the instructions and crossovers ‘ARE’ hooked up correctly. I’ll post pictures in a couple days here and an update after break in period.Caution: Having a phase plug, there is no sealed dust cap and whilst installing the driver, a piece of wood grain fell off my arm, straight down the cone, past the phase plug and settled nicely somewhere in the voice coil, now randomly I get huge distortion (blown sounding) in that mid woofer; I have to push cone back to knock it back out... temporarily. So unlike the regular dust cap protecting VC cones, dust is now an issue.I welcome feedback for I’d like to make the most of my last speaker purchases for a long time. Had to roll up my Texas Mickey full of change to buy these!Simon

Is tweeter exchangeable with the fabric (soft) dome version?

Asked by: theatro
Unfortunately you will have to purchase the individual parts if you want the silk dome version of that tweeter, we cannot substitute components.

Is this for one speaker enclosure or two for stereo?

It looks like enough to build one side . Why not make it less confusing? I almost bought this thinking I would have two speakers.
Asked by: clod
Selling them individually allows the buyer to purchase however many they may want for their system (like 3 for their LCR or 5/7 for a full surround system) and not be limited to multiples of two.

Can someone give me advice on a cylindrical cabinet dimension?

I'm a product designer, and I'm just getting into speaker building (mostly as a hobby). My goal is to create a set of speaker boxes, using this kit, that are half-cylinders (when not in use the speaker faces could potentially face each other creating a full cylinder). If the inside diameter of the enclosure is 8", how deep do I need to go? I may house the crossovers in a compartment below the top enclosure. Any advice or alarms with the shape would be helpful.
Asked by: Alex R.
Design and engineering are strange bedfellows... Start with your vision, but engineer backwards. You have to have a flat baffle for the drivers to mount to. Behind that, you need to have the correct cubic volume, in this case, .25 cu ft. Using pi-r-squared, you can determine the size of the cabinet using a curved surface. Generally speaking, this project won't easily lend itself to the shape. Larger cabinets would. There was a speaker in the 80's that used a cardboard tube with a section cut out for the front baffle. It was a very good product both visually and inherently acoustically due to the properties of the cabinet and construction. Outside of your design concept - you are just dealing with simple math. Good luck.

Why does the Dayton Audio Loudspeaker Kit Components Manual show the kit as a 4 ohm ? Does the kit come in two versions ? If so display the 8 ohm !

Asked by: thor61
The manual we have posted on the website, which should be the same one you receive with the kit, clearly states that the impedance of this kit is 8 ohms. I apologize for any confusion. If you received the wrong manual with your kit, please contact us at 1-800-338-0531 and we'd be glad to send you the correct manual.
