Sparky Mark

Pablo bought my lovely abm300 head. Very smooth deal with great communications. Thanks Pablo.

Bought Mike's diddly bow bass. Arrived via ups interparcel safe and sound exactly as agreed. Highly recommended seller.

I have only tried a 102H in a shop so wasn't able to compare with the 112H. All I know is that I like the sound of the mb 12 combos and cabs which are a narrower format than the 210. If I want louder I just add another 12 cab. Common sense tells me that a cmd102h combo with a 102 front ported extension cab would be louder still.

I don't have any experience with either of those but I have owned plenty of amplification over the last 35 years. The markbass combos all contain the LM2 or 3 head which I think is key to their ability to cut through the mix. It is a solid state analogue (not class D digital) amplifier which has quite a warm delivery for its type. In my experience it makes almost any cabinet sound good. The great thing about the combos is that you can pick them up on BC for a few pounds more than a used LM2/3. I don't think that there are too many light weight combos out there with such highly regarded power sections for approximately £500.

I would recommend a Markbass CMD121H which is the bigger brother to the 121P combo. It has a deeper more open delivery and partnered with a TRV121H cab will handle most situations. Of course if you are playing arenas or with 100w 4x12 full volume guitards you will struggle with any combo IME.

Quote "Bill is right though about the tweeter, There is virtually no energy at all above 5kHz where the horn you suggested using starts, so little or no point in adding it unless string noise is something you look for!" The Ht 30 response curve indicates usable output from around 2.5 / 3kHz. So if the MB crossover is at 3.5kHz for all their horns (and the same one is in this combo) then should be okay. It certainly sounds okay to my ears and I also have a CMD121H combo.

I disconnected the original one first of all but thought the sound a bit too dull hence buying the HT 30. I found the original harsh and too present. The ht is much more balanced/subtle/refined/not in your face IME.

I removed the front grill. I then unscrewed the 3 tweeter screws and lifted the tweeer enough to be able to remove the spade connectors. I then pushed the spade connectors onto the spades on the new tweeter and fed it back into the tweeter mounting hole in the combo. I used 4 matching black pan head screws to secure the HT30. This hole is slightly too small which means the ht doesn't sit perfectly flush but as this is a vented enclosure I am not concerned about having a perfect seal around the tweeter. The 4 fixing screws ensure that the tweeter is held securely. If you are bothered you can open the hole up slightly to allow flush mounting. Seemed like too much bother and mess to me.

I haven't actually looked at what crossover is used in my traveller 121H cab but others have said it is the same as the one in the CMD121H and CMD121P combos. If that is the case then this crossover works with 8ohm loads. The stock tweeter is so bad that I just don't understand why MB fit it. The small ht horn is much more refined and just adds a nice level of clarity to the top end. I haven't had the opportunity to use it at full volume yet to see if anything fails but I will report back when I have. I'm sure that if any of the other people who have fitted an ht30 had a problem they would've told us.

I have replaced the stock tweeter with an HT 30 and it's killed that annoying hiss and doesn't spit and ring like the original. Sounds much much better. The top end is now the same as my other horn fitted MB cabs. Best £11 upgrade you can make on a £600 combo IMO.
