Default Bought myself a Christmas present....

I have be running rear ported Polk "monitor 30" speakers for my apartment multi media sys.
However I'm still having problems with the rear ports causing nasty peaks when placed in the only I spot can use them. Everytime I think I have everthing balanced, I discover this or that problem caused by the rear facing ports...... I now have now about given up on them.

So, I finally decided to look for new speakers.
I found and ordered a Dayton "RS621CBK" speaker (pair) kit.
They fit my criteria.........
It''s an acoustic suspension sys, the correct height, and its the right price. They have to be better than the cheap HT Polks designed for the ignorant masses. They wiil be used with my reworked sub

At least it's a kit so, it's sort of DIY.
It seems like a quality sys for the price... check out the video on PE
Dayton Audio RS621CBK Speaker Kit Pair Curved Gloss Black 302-961

Anyway, anyone got any opinions on them?

Some speakers come with plugs to block the ports. Why don't you try that?

They are excellent drivers. You can see some measurements and comparisons at zaphaudio.com.

I tried blocking the ports in the past even though they are not designed to block. However, I was ultimately not happy with it.

Keep in mind the "Polk montor 30" speakers are designed for the mass HT market and produce unnatural bass, etc. The pair only cost about $100.

Also, no mater how I try to EQ them, they are very fatiguing to listen to for any prolonged period. Their distortion level is relatively high even at moderate volume using a 50w RMS per channel amp
They are OK for their price point and purpose but, are not "audiophile quality" by any stretch.

I have hope for this higher qualty, acoustical suspension speaker.

BTW the sub I am using is a Dayton "Sub-80" with a Tang Band "W8-740P" driver.
I'm very happy with it for my purpose.

I bet they're a big step up for you. I haven't heard them, but I understand that the driver line for the 6" is a good value. I like to build the boxes, but that sometimes produces a ... rustic look. You'll be rockin out in no time. The sealed mains should integrate to the sub better as well.

I woul love to build my own boxes but, I no longer have access to any nessary wodworking tools as I presenly live in an apartment.

Anway, yes the seal boxes should be much better for my purpose and also give a tighter mid bass.

I am presently using the sub's high pass for the mains and the more I EQ the Polks to compensate for the ports, the more it effects the sub. I also have to set the sub's high pass too high to compensate for the ports.
I just want to use the sub for the lowest freq possible while mataining a relatively flat response from the mains, using as littlle low end EQ as possible.

With the closed box bookshelves I'd probably start out trying to not even use the sub's HP for them (though it could be worth trying, depending). One would hope that the closed box would take care of the lows in a nice, natural way. And having moved from a sub high-pass to a dedicated active cross box I can confirm that in my case at least the plate amp didn't do any favors for the high frequency signal. Ditching that influence alone would be a big plus.

You maybe knew all that already, I just thought I'd say it...

Merry Christmas, enjoy the new setup!

Actually, I was thinking about trying that eventually.
