MTX Monitor 5i 5-1/4" 2-Way Bookshelf Speaker Pair
MTX Monitor 5i 5-1/4" 2-Way Bookshelf Speaker Pair is rated 4.0 out of 5 by 24.
Rated 5 out of 5 by from Nothing Sounds Better for the CostI have used these speakers daily for six years now, driver by a Pyle Mini amplifier. Everyone who hears them is always amazed at the incredible sound quality that can come from these little guys. This setup easily rocks the upper story of your home! I did open the box and change some of the caps like other customers have mentioned, honestly I don't think that improved the sound quality (which was already excellent out of the box). Maybe stuff some hollow fill sound-deading down the bass port if you are a stickler, but if you are really THAT concerned with the utmost quality in audio just spend $800 on your bookshelf speakers...

Rated 3 out of 5 by from Both wow and meh. Great for the price.I've had these speakers for quite a while now and go back and forth about them. On the one hand, the mids and lows are excellent, with the lows being extremely impressive coming from a speaker of this size. The grills are great quality and nice looking, and the main driver and internal wiring are very high quality (all soldered connections). On the other hand, I needed to use a EQ to get rid of the excessive highs, but the highs are still really harsh sounding. The other major downside is the boxes, which have pretty poor build quality. The vinyl veneer is peeling off at a few of the corners and the boxes must have been sanded before the application of the vinyl, because they're not actually flat. If the tweeter had been better I could look past the issues with the boxes, but overall I'm still very happy with these speakers.

Rated 5 out of 5 by from Great valueI bought these as an upgrade to an old pair of Realistic Minimus 7 speaker I use with a digital amp for "portable" hifi system. These sound very good for the money.

Rated 3 out of 5 by from Averge sound to me. Better with mods.I tried the 1.5uf cap and highs were way subdued (later found out it is not appropriate for the current shipping version). Changed to a 2.7uf cap. I stuffed the cab with polyfill and blocked the port to see if they're any better. A little better, but not great. I think they could use a better tweeter.

Rated 3 out of 5 by from Average and justI did a capacitor upgrade (027-326), a damping mat upgrade (268-036) and also glued two small cotton balls in the rear corners of each speaker to take up a bit of resonance and "tweak" the bass. The capacitor did take the midrange down but these are still pretty bright (with less midrange). I think a little more insulation (cotton or whatever) would be welcome to increase the bass a little, I don't think they will distort if you take it easy and the woofers can go a bit lower than with the stock cabinets. If I did this again I would skip the damping sheet and just go with adding a moderate amount of insulation. What you will end up with is a pretty cheap speaker that you might be able to get to sound a little better, but I was not looking for audiophile so that's OK with me. Think how music sounds in the dentist's office and that's about what you get. If you are really looking for a good speaker, you should spend a few bucks more.

Rated 5 out of 5 by from Good deal as part of a configurationThis seems to be a reasonable budget solution for surround speakers.I purchased this set for under $500 total:DAYTON AUDIO SUB-1200 12" 120 WATT POWERED SUBWOOFERMTX MONITOR 60I DUAL 6-1/2" 2-WAY BOOKSHELF SPEAKER PAIRMTX MONITOR 6C DUAL 6-1/2" 2-WAY CENTER CHANNEL SPEAKERMTX MONITOR 5I 5-1/4" 2-WAY BOOKSHELF SPEAKER PAIRI’m not an expert, but from my perspective, this (or similar) configuration is all you need for a good size family room. My family room is 20’ by 13’ and it fully opens to a kitchen of the same size (all speakers are set up in the room itself). I can now hear the music load and clear, even in the kitchen. In my experience, a more difficult challenge for speaker systems is to be able to hear a conversation from a TV program at a longer distance. With this set, I can also hear a conversation from a TV load and clear (!) even when doing something in the kitchen in a distance of about 40’ (and I have some hearing difficulty). BTW, a 100 Watt subwoofer might have been sufficient, but the price was the same at the time, so I bought 120 Watts.It seems that buying this type of configuration is a better deal than a Home Theater Speaker System.However, make sure you have enough space for the speakers (pretty large) and space on the floor for the subwoofer, which is large and heavy (you may need to explain to your spouse that it just needs to be like that :-)).

What is the size of the clip terminals on the back? Curious because I want to buy these but replace them with Banana plug terminals.

Asked by: NewAudioBuyer
It looks like these use a very similar press fit style terminal as the one below. After a rough measurement, the cutout appears to be 1-7/8" diameter.

Adding an inductor.

So if a capacitor helps out the tweeters, would applying an inductor help the woofer? And if not, how easy are these to work with in terms of swapping out speakers to achieve better sound?
Asked by: Hansuman
I looked at the documentation for this speaker and there is no schematic available to review what the manufacturer has done with it internally. Typically, there is an inductor rolling off the woofer at 6db/oct and another network rolling off and protecting the tweeter at 12db/oct. You should have no need to modify the crossover. If you do want to upgrade the drivers, the crossover would remain the same only if the new driver had the same efficiency as the other and had the same cabinet size requirements. It's usually better just to buy another speaker or build a new project...
